Vapor Intrusion Mitigation Plan – Rev. 1 West Morehead II Brownfields Property The Falcon 2131, 2211, and 2233 West Morehead Street Charlotte, North Carolina Brownfields Project No. 23031-19-060 H&H Job No. PHL-001
1.0 Introduction

On behalf of Panorama Holdings, LLC (Prospective Developer or PD), Hart & Hickman, PC
(H&H) has prepared this Vapor Intrusion Mitigation Plan (VIMP) for the West Morehead II
North Carolina Department of Environmental Quality (DEQ) Brownfields Property (Brownfields
Project No. 23031-19-060).

The West Morehead II Brownfields property (Site or subject Site) is located at 2131, 2211, and
2233 West Morehead Street in Charlotte, Mecklenburg County, North Carolina and is comprised
of two contiguous parcels of land (Parcel Identification Numbers 06702118 and 06702114) that
total approximately 4.68 acres. A Site location map is provided as Figure 1, and the Site and
surrounding area are shown on Figure 2.

The western Site parcel appears to have been developed with the current commercial buildings as
early as 1983, and the eastern Site parcel appears to have been developed with the current
warehouse building in 1997. Since the late 1990s, historical operations at the Site have included
several office tenants, a tile/stone showroom, and woodworking and stone cutting/finishing
operations. The western parcel is currently developed with an approximately 13,800-square foot
(sq ft) office building (2211 W. Morehead Street) and an approximately 3,200-sq ft warehouse
building (2233 W. Morehead Street). The eastern parcel is developed with an approximately
13,500-sq ft warehouse building (2131 W. Morehead Street). Currently, the office building and
eastern warehouse are utilized by The Marble and Stone Shop as offices, a showroom, and a
stone cutting and finishing facility. The western warehouse is utilized by Wood Design as a
custom furniture and cabinetry shop.

Previous assessment activities conducted at the Site indicated the presence of volatile organic
compounds (VOCs) in groundwater, exterior soil gas, and sub-slab vapor. To address potential
environmental concerns associated with the Site, the PD elected to enter the Site into the DEQ
Brownfields Redevelopment Section and received eligibility in a letter dated June 13, 2019. It is
H&H’s understanding that a Notice of Brownfields Property (Brownfields Agreement) is
currently in development between the PD and DEQ.

The PD plans to demolish the existing Site structures and redevelop the Site with one mixed-use
commercial and high-density residential apartment building (Building 1) on the western portion
of the Site, and one high-density residential apartment building (Building 2) on the eastern
portion of the Site. Both buildings include open-air parking decks. The proposed development
is referred to as The Falcon. Based on the Site information presented in Section 1.1, a vapor
intrusion mitigation system (VIMS) will be installed within the Site buildings as detailed in the
VIMS design drawings included as Attachment A.

1.1 Background

In March 2019 and April 2020, H&H performed Phase II Environmental Site Assessment (ESA)
and Brownfields Assessment activities at the Site. Assessment activities included the collection
of soil and groundwater samples for laboratory analysis to evaluate the potential for impacts to
the Site from historical on-Site and off-Site commercial and industrial operations. Results of the
assessment activities are documented in a Phase II ESA dated April 11, 2019 and a Brownfields
Assessment Report dated May 29, 2020.

To further evaluate the potential for vapor intrusion into the proposed Site buildings, H&H
performed supplemental Brownfields Assessment activities at the Site in September 2022.
Assessment activities included the collection of exterior soil gas and sub-slab vapor samples for
laboratory analysis. Results of the assessment activities are documented in a Brownfields
Assessment Report prepared by H&H and dated February 7, 2023. Tabular summaries of
previous assessment data and a figure depicting the locations of previous samples are provided in

Attachment B. A brief summary of the sampling activities and results pertinent to potential
vapor intrusion for the Site buildings is provided below.

Groundwater Sampling
In March 2019, groundwater sampling activities at the subject Site included installation and
sampling of three (3) temporary monitoring wells (TMW-1 through TMW-3). Laboratory
analytical results of the March 2019 groundwater samples indicated the presence of
tetrachloroethylene (PCE) in TMW-1 (4.4 microgram per liter [µg/L]) and TMW-2 (3.9 J µg/L)
above the DEQ 2L Groundwater Quality Standard (2L Standard) of 0.7 µg/L but below the DEQ
Residential Vapor Intrusion Groundwater Screening Level (GWSL) of 12 µg/L. Low levels of
the VOCs chloroform, cis-1,2-dichloroethylene, and trichloroethylene (TCE) were also detected
above laboratory method detection limits but below their respective 2L Standards and
Residential GWSLs for vapor intrusion.

In April 2020, groundwater sampling activities included the installation and sampling of four (4)
additional temporary monitoring wells (TMW-4 through TMW-7) at the Site. Laboratory
analytical results indicated the presence of PCE in groundwater samples TMW-4 (1.3 µg/L),
TMW-5 (2.9 µg/L), TMW-7 (3.3 µg/L), and TMW-DUP (3.0 µg/L) at concentrations above the
2L Standard of 0.7 µg/L but below the Residential GWSL of 12 µg/L. Additionally, TCE was
detected in samples TMW-5 (7.0 µg/L), TMW-7 (3.2 µg/L), and TMW-DUP (3.3 µg/L) at
concentrations above the 2L Standard of 3.0 µg/L. The TCE detections in samples
TMW-7/TMW-DUP exceed the Residential GWSL of 1.1 µg/L, and the TCE detection in
sample TMW-5 exceeds the Non-Residential GWSL of 4.4 µg/L. Several other VOCs were
detected in the April 2020 groundwater samples above laboratory method detection limits, but
below the 2L Standards and GWSLs.

Soil Sampling
In April 2020, soil samples were collected at the Site to evaluate the potential for impacts in
areas of the Brownfields property planned for redevelopment. A total of four (4) soil samples
were collected from four (4) boring locations. Laboratory analytical results did not indicate the
presence of VOCs in samples SB-1 (0-2 ft) through SB-4 (0-2 ft) at concentrations above the
4
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
Residential or Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs). No
chlorinated solvents were detected in the soil samples at concentrations above the laboratory
method detection limits.

Exterior Soil Gas/Sub-Slab Vapor Sampling
In September 2022, 12 exterior soil gas samples (SG-1 through SG-12) and five (5) sub-slab
vapor samples (SSV-1 through SSV-5) were collected at the Site. Laboratory analytical results
of the September 2022 exterior soil gas and sub-slab vapor sampling activities identified several
VOCs at concentrations above the DEQ Division of Waste Management (DWM) Residential
Soil Gas Screening Levels (SGSLs) including benzene, benzyl chloride, chloroform,
ethylbenzene, naphthalene, and vinyl chloride. In addition, TCE was detected at concentrations
exceeding both the Residential and Non-Residential SGSLs in several of the exterior soil gas and
sub-slab vapor samples collected at the Site. Several other VOCs were detected above the
laboratory reporting limits but below their respective DEQ DWM Residential and Non-
Residential SGSLs.

1.2 Vapor Intrusion Evaluation
To further evaluate the cumulative exposure risk associated with the soil gas concentrations
detected at the Site, H&H utilized the DEQ risk calculator to calculate the lifetime incremental
carcinogenic risk (LICR) and hazard index (HI) under hypothetical worst-case residential and
non-residential use scenarios for each building utilizing the highest concentration for each VOC
detected. Typically, vapor intrusion mitigation for a building is not warranted unless the LICR is
1 x 10-4 or greater for potential carcinogenic risks and/or the cumulative HI is 1.0 or greater for
potential non-carcinogenic risks. The DEQ risk calculator results for the soil gas to indoor air
pathway indicate a non-carcinogenic HI in Building 1 (3.3) and Building 2 (1.6) that are above
the acceptable risk level for residential use. Copies of the DEQ risk calculator output sheets are
provided in Attachment B.

Based on review of the laboratory analytical data and risk evaluation results, potential structural
vapor intrusion for Building 1 and Building 2 can be managed through installation of passive
5
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
vapor intrusion mitigation measures during construction of the proposed mixed-use commercial
and residential buildings. The PD plans to install a passive VIMS, with the ability to become
active with the installation of electric fans, during construction of the proposed buildings as
described herein. Installation of the VIMS is anticipated to satisfy the following Land Use
Restriction (LUR) which is anticipated to be standard language in the pending Brownfields
Agreement:

No enclosed building may be constructed on the Brownfields Property and no existing
building, defined as those depicted on the plat component of the Notice of Brownfields
Property referenced in paragraph 18 below, may be occupied until DEQ determines in
writing that:
i. the building is or would be protective of the building’s users and public health from the
risk of vapor intrusion based on site assessment data, or a site-specific risk assessment
approved in writing by DEQ; or
ii. a vapor intrusion mitigation system (VIMS) has been:
1. designed to mitigate vapors for subgrade building features in accordance with the
most recent and applicable DWM Vapor Intrusion Guidance, Interstate Technology
& Regulatory Council (ITRC) guidance, and American National Standards Institute
(ANSI)/American Association of Radon Scientists and Technologists (AARST)
standards, and that said design shall fully protect public health to the satisfaction of a
professional engineer licensed in North Carolina, as evidenced by said engineer’s
professional seal, and shall include a performance monitoring plan detailing
methodologies and schedule, both of which are subject to prior written DEQ
approval; and
2. installed and an installation report is submitted for written DEQ approval that
includes details on any deviations from the system design, as-built diagrams,
photographs, and a description of the installation with said engineer’s professional
seal confirming that the system was installed per the DEQ-approved design and will
be protective of public health.

Engineer’s Certification
According to the DWM Vapor Intrusion Guidance: “Risk-based screening is used to identify
sites or buildings likely to pose a health concern, to identify buildings that may warrant
immediate action, to help focus site-specific investigation activities or to provide support for
building mitigation and other risk management options including remediation.” In addition, this
VIMP was prepared to satisfy the standard vapor intrusion mitigation provisions anticipated to
be included in the pending Brownfields Agreement. Per the North Carolina Brownfields
Property Reuse Act 130A-310.32, a prospective developer, with the assistance of H&H for this
project, is to provide NCDEQ with “information necessary to demonstrate that as a result of the
implementation of the brownfields agreement, the brownfields property will be suitable for the
uses specified in the agreement while fully protecting public health and the environment instead
of being remediated to unrestricted use standards.” It is in the context of these risk-based
concepts that the H&H professional engineer makes the following statement:

The vapor intrusion mitigation system detailed herein is designed to mitigate intrusion of
subsurface vapors into the subject buildings from known Brownfields property contaminants in a
manner that is in accordance with the most recent and applicable guidelines including, but not
limited to, DWM Vapor Intrusion Guidance, Interstate Technology & Regulatory Council
(ITRC) guidance, and American National Standards Institute (ANSI)/American Association of
Radon Scientists and Technologists (AARST) standards. The sealing professional engineer
below is satisfied that the design is fully protective of public health from known Brownfields
property contaminants.

2.0 Design Basis
The VIMS design drawings for The Falcon development are included in Attachment A. The
following VIMS design sheets and will be used to guide construction of the VIMS:
• Sheets VM1-1, VM1-2, VM1-3, and VM1-4 show the VIMS layout in Building 1;
• Sheets VM2-1, VM2-2, and VM2-3 show the VIMS layout in Building 2; and
• Sheets VM-A, VM-B, and VM-C include section details and specifications for both
buildings.

To reduce the potential for structural vapor intrusion, the VIMS in Building 1 and Building 2
will operate as passive sub-slab venting systems that include a network of horizontal sub-slab
and vertical above-slab riser piping that will discharge collected vapors above the building
roofline.

The proposed development plan includes two residential apartment buildings, Building 1 and
Building 2. Building 1 is a seven-story apartment building that will be column-supported with a
concrete slab-on-grade and will not contain pour back spaces. The ground floor of Building 1
will contain a leasing office/amenity/lobby area in the northeastern portion of the building with
no residential living spaces proposed on the ground floor. The second floor will contain a co-
working / commercial space. The third and fourth floors will contain residential apartment units,
an area for future commercial tenants including a restaurant, and an open-air courtyard. There is
a vent shaft that runs from the third floor to the building roof. This vent shaft will installation of
ducts and air exhaust from the commercial areas to discharge above the building roofline. The
vent shaft does not contain openings that connect with the hallways or living spaces, and
therefore will not exchange air with living spaces. Floors five through seven of Building 1 will
contain residential apartment units and an open-air courtyard. Additionally, Building 1 will
contain a flat roof with mechanical equipment, and vertical retaining walls are proposed for the
northern, southern, and western walls as shown on VM1-1.

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
The ground floor and second floor of Building 1 will also contain an open-air parking deck
structure with residential units and the open-air courtyard located above the parking deck. There
are two stairwells and elevators located in the parking deck that connect to upper floors and thus
could exchange air with the upper floors through the doorways; however, the stairs and living
spaces on upper floors do not share the same heating, ventilation, and air conditioning (HVAC)
systems. Further, there is an elevator lobby adjacent to the elevator in the northern portion of the
building and several utility rooms located in the parking deck. The ground floor areas of
Building 1 proposed to contain VIMS measures are included in the following table:

Building 1 Area Approximate Ground Floor
Enclosed Area (sq ft)
Leasing office / Amenity Area 7,400
Utility Rooms 1,170
Parking Deck Stairs / Elevators 730

Building 2 is a six-story apartment building and will be split into two ground-floor levels,
Level 1 and Level 2, with an open-air parking deck and vertical retaining walls between the
building sections. The Building 2 parking deck includes two exhaust vent shafts that allow air to
exhaust from the parking deck to above the building roofline. These garage exhaust vent shafts
do not contain openings into the hallways or livings spaces and therefore will not exchange air
with living spaces. The building plans do not include proposed pour-back or retail spaces.
Please note, a previously proposed retail portion of Building 2 has been modified to be an
amenity space for the residential tenants as depicted in the design drawings (Attachment A).
Building 2 is proposed to contain a slab-on-grade with thickened slabs below load-bearing walls.
Building 2 will also contain a flat roof with mechanical equipment. The approximate enclosed
ground floor areas for Building 2 are listed in the table below.

Building 2 Area Approximate Ground Floor
Enclosed Area (sq ft)
Level 1 Residential Units 12,000
Level 2 Residential Units 19,100

2.1 Base Course Layer and Vapor Barrier

The VIMS includes placement of a minimum 4-inch base course stone (gravel) layer consisting
of high permeability stone (washed #57 stone, or similar high permeability stone approved by the
VIMS design engineer certifying the VIMP [design engineer]) below the concrete slab of the
building. A vapor barrier (vapor liner) will be installed above the base course stone layer and
directly beneath the slab. The vapor barrier will also be installed underneath of and along
vertical walls within elevator pits and on vertical sub-grade retaining walls backfilled with soil
that are located adjacent to enclosed or occupiable spaces. The specified vapor barrier and
waterproofing materials in these areas will be evaluated for compatibility. A horizontal
collection piping network will be installed within the base course stone layer below the ground
floor slabs prior to placement of the vapor barrier. The horizontal vapor collection piping is
discussed further in Section 2.2. below. The piping layouts are shown on the VIMS design
drawings (Attachment A).

The vapor barrier will consist of a VOC-tested and rated vapor barrier, such as Vaporblock®
Plus 20 (VBP20) manufactured by Raven Industries (Raven), or Drago® Wrap Vapor Intrusion
Barrier (Drago Wrap) manufactured by Stego® Industries (Stego). Vapor barriers will be
installed per manufacturer installation instructions. Technical specifications for each vapor
barrier product listed above are included in Attachment C.

The vapor barriers will be installed over the base course stone layer or applicable vertical sub-
grade walls and footers to cover the areas shown on the design sheets. Each vapor barrier
manufacturer recommends select sealing agents (mastics, tapes, etc.) for their vapor barrier
product. In accordance with manufacturer installation instructions, alternative vapor barrier
products that are not approved by the manufacturers for sealing shall not be used, unless
approved by the design engineer and specific manufacturer.

The exterior edges of the vapor barrier will be attached and sealed to building footings and
subsurface concrete features utilizing the tape specified in the manufacturer instructions. Seams
within the building envelope will have a minimum of 6 inches or 12 inches of overlap
10
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
(depending on the vapor barrier manufacturing specifications) and will be sealed with the tape
specified in the manufacturer instructions. If the vapor barrier is damaged, torn, or punctured
during installation, a patch will be installed by overlaying a piece of vapor barrier that is cut to
the approximate shape of the damaged area and sized such that a minimum of 6 inches of patch
surrounds the damaged area. The seams of the patch will then be sealed using the manufacturer
recommended tape.

In areas where utility penetrations (i.e., piping, ducts, etc.) are present and the use of the tape
recommended by the manufacturer is not practical or deemed as “ineffective” by the design
engineer certifying the VIMP, an alternative sealant product specified by the vapor barrier
manufacturer should be used, such as Raven Pour-N-Seal™, Drago Sealant™, or similar vapor
barrier manufacturer sealing products. If used, the location of these products will be noted in the
field logs. Following successful installation of the vapor barrier, the finished concrete slab will
be placed directly on top of the sealed vapor barrier to further seal the seams and penetrations.
2.2 Horizontal Collection Piping and Vertical Riser Piping

Passive sub-slab venting will be accomplished using horizontal slotted or perforated collection
piping which will collect vapor from beneath the occupiable and enclosed ground floor slab areas
and discharge the vapors above the building roofline. Both sub-slab and above-slab piping will
consist of 3-inch diameter Schedule 40 (SCH 40) PVC piping and fittings, unless otherwise
specified in the design drawings (Attachment B). Solid sections of VIMS piping shall maintain a
minimum 1% slope toward slotted sections to drain potential condensation water. Product
specifications for the sub-slab collection piping are provided in Attachment C.

The vertical riser pipes will terminate above the roofline. While a passive system can effectively
operate without rooftop ventilators, to further enhance the passive VIMS, Empire Model
TV04SS (stainless steel) wind-driven turbine ventilators (or design engineer approved
alternative) will be installed on the discharge end of the 3-inch SCH 40 PVC vertical riser piping
above the building roofline to further promote air exhaust from the risers. The ventilators will
generally be located on areas of the roof that receive effects from wind under normal weather
conditions. However, as the ventilators are intended to enhance the passive VIMS and aren’t
11
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
required for proper function of the system, some ventilators may be positioned in areas that
receive intermittent effects from wind based on the building layout and other building
components. The requirements for the discharge location based on distances to building
materials, operable openings, air intakes, etc. will be followed as indicated in the design
drawings and applicable building code.

To aid in identification of the vapor mitigation piping, the piping will be labeled by the Site
contractors with stickers adhered to a smooth surface or permanent labels which read, “Vapor
Mitigation – Contact Maintenance”, or similar language, on accessible piping at intervals of no
greater than 10 linear feet. Similar labels will also be affixed near the exhaust discharge on the
roof. VIMS labeling will be inspected by H&H prior to covering risers or building occupancy.

Exhaust discharge locations must be a minimum of 2 ft above the roofline and a minimum 10 ft
from an operable opening (e.g., door or window) or air intake into the building. Note that the
exhaust locations on the roof depicted in the VIMS design may be repositioned within the
requirements specified above and pending approval by the design engineer certifying the VIMP.
Product specifications for the proposed turbine ventilators are provided in Attachment C.
Electrical junction boxes (120VAC, min 15-amp required) will be installed on the roof in close
proximity to riser exhaust discharges should connection of an electrical (active) fan be warranted
in the future.

2.3 Monitoring Points

Monitoring points constructed with 2-inch diameter SCH 40 PVC will be installed as part of the
VIMS to conduct effectiveness testing (see Section 4.0), including vacuum influence
measurements, and for the collection of sub-slab soil gas samples for laboratory analysis. The
monitoring point locations are shown on the VIMS design drawings (Attachment B).

In general, monitoring points are placed at remotely distant locations from vertical riser piping
locations and in representative areas of the ground floor enclosed areas. To limit disturbance to
residents or occupants during future monitoring events, the majority of the monitoring point
12
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
access ports will be located in mechanical rooms, amenity spaces, or corridor hallways and
protected by either a floor clean-out style cover or wall access panel. Monitoring points located
in stairwells must be located beneath accessible stair landings or in areas away from the main
tenant walkways. In select areas, the monitoring point will contain an exterior mounted access
port protected by an outdoor enclosure or irrigation style box if installed flush with the exterior
ground surface. Several monitoring points will be connected to extended sub-slab horizontal
pipes which place the intakes of the monitoring points below occupied spaces. The extended
monitoring points are expected to have no more than approximately 6 ft of extension pipe.
Product specifications for the proposed monitoring point components are provided in
Attachment C.

One temporary monitoring point (TMP-1 is proposed for the northeast corner of the Building 1
lobby area. This area is proposed to have finished tiled flooring and thus a permanent
monitoring point is not recommended in this area. TMP-1 will be used to measure vacuum
during pilot testing (Section 4.0), then the point will be abandoned prior to finishing activities
per approval of the design engineer certifying the VIMP and DEQ. The temporary point will be
abandoned by removing the pipe to the extent possible, filling in the hole with an air-tight sealant
(such as Raven Pour N Seal), then patching the concrete to match the surrounding area.

In the event that a monitoring point cannot be installed due to building component conflict or is
damaged/destroyed during construction, a replacement monitoring point can be constructed,
pending approval by the design engineer certifying the VIMP. The replacement point(s) shall
consist of one of the specified designs in the design drawings. DEQ will be notified in advance
for approval if monitoring points are notably relocated in relation to the approved locations
specified in the VIMP (i.e., if moved to a location in a different mitigation area, section of slab,
or tenant area). The specific types and locations of monitoring points installed will be
documented in as-built drawings provided in a VIMS installation completion report.

2.4 General Installation Criteria
The VIMS installed components (e.g., vapor barrier, piping, monitoring points, etc.) shall be
protected by the installation contractor and sub-contractors throughout the project. Protective
measures (e.g., flagging, protective boards, etc.) shall be used as needed to prevent damage to the
VIMS components. For example, the monitoring points and riser duct piping should be capped
with a removable slip-cap or cover immediately following installation to prevent water and/or
debris from entering the VIMS, and vapor barrier shall be protected from punctures and tears
during site-work.

For each phase of construction (above and below slab), construction contractors and sub-
contractors will be instructed to use “low or no VOC” products and materials, when possible.
Furthermore, the construction contractors will be instructed to not use products containing the
compounds PCE or TCE. Prior to submittal of a VIMS installation completion report, the
construction contractor and sub-contractors shall be directed to provide safety data sheets (SDSs)
for products and materials used during construction. SDSs provided by the contractor and sub-
contractors will be included in the VIMS installation completion report.

Utility Trench Dams
Based on the location and presence of chlorinated solvents on the property, a utility trench dam
as detailed in the design drawings (Attachment A) will be installed along the utilities, including
sanitary sewer and potable water lines, that contain a transmissive backfill layer (e.g., sand,
stone, screenings) and extend underneath the building footprint. The utility trench dams will
serve as a dam for vapors from traveling along the utility trenches and below the footprint of the
building.

3.0 Quality Assurance / Quality Control
For quality assurance and quality control (QA/QC) purposes, inspections will be conducted
during each phase of VIMS installation. The components that require inspection are outlined
below:
(1) Inspection of vapor barrier along the sub-grade elevator pits and applicable vertical
retaining walls prior to backfilling;
(2) Inspection of the base course stone layer, sub-slab piping layout, and monitoring points
prior to installing the vapor barrier;
(3) Inspection of the vapor barrier below slab areas prior to pouring concrete;
(4) Inspection of above-grade vertical riser piping; and
(5) Inspection of riser pipe connections, pipe exhaust, and ventilators.

Additional inspections will be conducted if the system(s) are activated to verify electric fans (if
installed) are functioning properly. Each inspection will be performed by, or under direction of,
the design engineer certifying the VIMP. Inspections will be combined, when possible,
depending on construction sequencing and schedule. The inspections will include field logs and
photographs for each section of slab. To minimize potential preferential pathways through the
slab, contractors will not use hollow piping to support utilities in preparation for concrete pours.
Contractors will be instructed to remove hollow piping observed during the field inspections.
The contractor shall notify the engineer certifying the VIMP, or his/her designee, with a
minimum 48-hour notice prior to a planned inspection, and H&H will provide a subsequent 2-
business day notice to DEQ for the pending inspection.

4.0 VIMS Effectiveness Testing
4.1 Influence Testing

Post-installation (pre-occupancy) influence testing will be conducted on each VIMS treatment
area to evaluate vacuum communication across the slab and confirm sufficient depressurization
can be obtained should electric fans be needed in the future. Influence testing will be conducted
for each treatment area following installation of the horizontal collection piping, placement of
the vapor barrier, and completion of concrete slab pours. A 2-business day notice will be
provided to DEQ prior to each influence test.

For system influence testing, one or more vapor extraction fans will be attached directly to
vertical riser piping for the section of the slab being evaluated. Pressure differential will be
measured at extraction fan locations and sub-slab vacuum levels will be measured at each
monitoring point location. While any measurable sub-slab vacuum level can indicate there is
influence below the slab, a pressure differential below the slab of at least 4 pascals
(approximately 0.016 inches of water column [in-WC]) at remote distances from riser location in
each VIMS treatment area may be considered as sufficient evidence of adequate sub-slab VIMS
influence per evaluation by the design engineer certifying the VIMP. Vacuum influence testing
results will be included in the VIMS installation completion report. If the influence testing
results indicate that modifications to the VIMS are needed to achieve sufficient sub-slab
depressurization, H&H will notify DEQ of the modifications prior to submittal of a VIMS
installation completion report.

4.2 Pre-Occupancy Sub-Slab Soil Gas Sampling

Following VIMS installation, but prior to occupancy of the building(s), sub-slab soil gas samples
will be collected from select monitoring points to further evaluate the potential for structural
vapor intrusion. The sub-slab soil gas samples will be collected from locations generally
representative of the slab conditions. Sub-slab soil gas sample analytical results will be used to
evaluate potential risks to future occupants of the building. Six sub-slab soil gas samples are
16
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
proposed in Building 1 from monitoring points MP1-1, MP1-2, MP1-4, MP1-7, MP1-8, and
MP1-10. Eight sub-slab soil gas samples are proposed in Building 2 from monitoring points
MP-2-1, MP2-2, MP2-4, MP2-5, MP2-7, MP2-8, MP2-10, and MP2-12.

In addition, because of the detections of TCE in the previous groundwater, exterior soil gas, and
sub-slab vapor samples, indoor air sampling will be conducted as described below in Section 4.3.
A indicated below, the indoor air sampling event is anticipated to be conducted concurrently
with sub-slab sampling event. In this case, a duplicate sample for the indoor air sampling will be
collected for laboratory QA/QC during the sampling event. If the sub-slab vapor and indoor
sample events are not conducted concurrently, then separate duplicate samples will be collected
with a minimum of one duplicate per sampling event.

Prior to sample collection, leak tests will be performed at each sub-slab soil gas sample location.
A shroud will be constructed around the monitoring point and sub-slab soil gas sampling train
and sample canister. Air within the shroud will be flooded with helium gas, and helium
concentrations will be measured and maintained using a calibrated helium gas detector. With
helium concentrations within the shroud maintained, sub-slab soil gas will be purged from the
sampling point with an air pump and collected into a Tedlar bag. The calibrated helium gas
detector will be used to measure helium concentrations within Tedlar bag sample to confirm
concentrations are less than 10% of the concentration maintained within the shroud. A minimum
of three sample train volumes will be purged from each point prior to and during the leak testing
activities.

The sub-slab soil gas samples will be collected over an approximate 10-minute period using
laboratory-supplied, batch-certified 1-liter or 1.4-liter Summa canisters and laboratory-supplied
flow regulators calibrated with an approximate flow rate of 100 milliliters per minute. The
vacuum in the Summa canisters will be measured at the start and end of the sampling event and
will be recorded by sampling personnel. The vacuum in each canister at the conclusion of the
sampling event shall remain above 0 inches of mercury (inHg) with a target vacuum of
approximately 5 inHg. H&H understands that analytical results for a sample will not be accepted
by DEQ if internal vacuum for that sample reaches 0 inHg.
17
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
The samples will be submitted to a qualified laboratory under standard chain of custody
protocols for analysis of full-list VOCs by EPA Method TO-15, including naphthalene. The
analytical laboratory will be instructed to report vacuum measurements as received at the lab and
J-flag concentrations (concentrations measured between the laboratory method detection limit
and laboratory reporting limit) for each sample. In addition, H&H will request that the
laboratory report compound concentrations to the lower of the laboratory method detection limits
or to the extent possible, the DEQ DWM Residential SGSLs.

4.3 Pre-Occupancy Indoor Air Sampling

As summarized in Section 1.0, the VOC compounds PCE and TCE were detected in
groundwater, exterior soil gas, and sub-slab vapor samples at the Site. Therefore, in addition to
the sub-slab sampling, indoor air sampling will also be conducted within the proposed Site
buildings. The indoor air sampling will be conducted concurrently (within 48-hours) of the sub-
slab sampling for comparison for the data to evaluate the potential for vapor intrusion into the
buildings. To limit the potential for interference with the sampling results, the indoor air
samples will be collected prior to the corresponding sub-slab vapor sample. A total of three
indoor air samples (IAS1-1, IAS1-2, and IAS1-3) are proposed for Building 1, and five indoor
air samples (IAS2-1 through IAS2-5) are proposed for Building 2. The proposed locations for
the indoor air samples are depicted on Sheet VM1-1 (Building 1) and Sheets VM2-1 and VM2-2
(Building 2). Based on construction phasing, separate sampling events for Building 1 and
Building 2 may be conducted.

The buildings are intended to be occupied shortly following completion and initialization of the
HVAC system. Therefore, the indoor air sampling events will be conducted following
construction and installation of the VIMS and after the building or sample area is fully enclosed.
When possible, the indoor air sampling will be completed a minimum of two weeks following
completion of the risers and ventilators but may be conducted prior to initialization of the HVAC
system(s). The DEQ Vapor Intrusion Guidance, dated March 2018, indicates “higher indoor air
concentrations might be expected when a building is sealed up and the HVAC is not running”,
and “worse case conditions may also be considered when the building is closed up and the
18
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
HVAC system is not running.” Furthermore, HVAC equipment is typically not able to be
activated until approximately a few weeks prior to closing due to the timing of the Mecklenburg
County approval for installation of the gas and electric meters. Thus, conducting indoor air
sampling with the building enclosed, but prior to HVAC operation, may allow for a more
conservative indoor air sampling approach and will allow for time to conduct the pre-occupancy
sampling and reporting as required in this Plan prior to closing. In addition, HVAC equipment
isn’t operational until finishing activities including installation of flooring, cabinets, sealants,
paints, industrial cleaning, etc. are being conducted. Off-gassing of VOCs from these building
finishing materials and products can impact the indoor air concentrations and make it more
difficult to evaluate the potential for vapor intrusion. Thus, sampling ahead of HVAC operating
and finishing activities is proposed. However, if the sampling timing allows for HVAC to be
running at the time of the indoor air sampling, then the HVAC will be operational during
sampling. The status of the HVAC operation during the sampling event will be recorded in the
building survey form (see below).

The indoor air samples and background air sample will be collected using individually-certified
6-liter stainless steel Summa canisters connected to in-line flow controllers equipped with a
vacuum gauge. As a conservative measure, the flow controllers will be set by the laboratory to
allow the samples to be collected over an approximate 24-hour period in both the commercial
and residential areas of the Site buildings. Note, a 24-hour sampling period is based on a
residential use, and thus is a more conservative approach than performing an 8-hour sampling
period for the commercial spaces. Laboratory supplied 3-foot sampling cane, or similar
methods, will be connected to the flow controller so that the sample intake point is positioned
approximately 5 ft above grade (typical breathing zone height) when the sample canister is set on
its base. In addition, during each indoor air sampling event, one duplicate sample for laboratory
QA/QC and one background sample from an ambient air upwind locations will be collected.
Prior to and after the indoor and background air samples are collected, vacuum in the canisters
will be measured using a laboratory-supplied vacuum gauge and recorded by sampling
personnel. A vacuum above 0 inHg and ideally around 5 inHg will be maintained within the
canisters at the conclusion of the sampling event.

19
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
The starting and ending vacuum in each canister will be recorded on the sample chain of
custody. Periodic checks will be conducted by sampling personnel to monitor the pressure
within the Summa canisters during sampling to ensure adequate sample volume is collected. The
sample canisters will then be labeled and shipped under standard chain of custody protocols to a
qualified laboratory for analysis of select VOCs by EPA Method TO-15. The select compound
list will be based upon the VOC compounds that are part of the Method TO-15 list detected
above laboratory MDLs in any site media (groundwater, soil, and soil-gas) during previous
assessment activities. If additional compounds are detected in the sub-slab vapor samples that
weren’t detected previously on the Site, the laboratory will also be requested to report these
compounds in the indoor air sample results. Because the sub-slab vapor samples will be
collected concurrently with the indoor air samples and submitted together to the laboratory, the
laboratory will be requested to analyze the indoor air samples for the full TO-15 list, which is
normal laboratory procedure, but only report the select compounds requested. Note, in the event
that additional sub-slab vapor compounds are detected that weren’t previously detected in
historical samples, it’s likely the additional compounds would be associated with off-gassing of
sub-slab building materials and not associated with Site contaminants. Therefore, an evaluation
of the source of the additional compounds may be conducted based on review of the construction
material SDSs as indicated below. The analytical laboratory will be instructed to report vacuum
measurements at receipt and J-flag concentrations for each sample. H&H will request that the
laboratory report compound concentrations to the lower of the laboratory MDLs or to the extent
possible, the DEQ DWM Residential Vapor Intrusion Indoor Air Screening Levels (IASLs). In
addition, an Indoor Air Building Survey form (Appendix C of the DWM VI Guidance) will be
completed for each sampling event.

New construction materials such as treated lumber, paint, caulk, carpet, adhesives, sealants etc.,
which could be sources of VOCs in indoor air, may cause interference with Site-specific
compounds of concern during indoor air sampling. As previously noted, the construction
contractors will be instructed to provide SDSs for materials used during construction which will
be submitted to DEQ, if needed to further evaluate sub-slab soil vapor and indoor air data.

20

4.4 VIMS Effectiveness Results

Following receipt of analytical results, the laboratory report will be reviewed and DEQ will be
notified in the event that TCE concentrations in indoor air or sub-slab vapor indicate potential
vapor intrusion pathways may exist. In accordance with the DEQ DWM TCE Indoor Air
Inhalation Immediate Action Levels and Response guidance (dated July 2019), DEQ will be
notified within 24 hours if TCE is detected at a concentration exceeding 2.1 µg/m3 in indoor air
based on the residential use of the building. Note, that no residents will be living in the building
during the post-construction indoor air sampling and that some areas are proposed to contain
commercial spaces. DEQ will also be notified prior to report submittal if sub-slab and indoor air
samples indicate a completed vapor intrusion pathway exists to discuss whether additional
sampling or other measures are warranted. The results and analysis of the sub-slab vapor and
indoor air sampling will be submitted to DEQ with the VIMS Installation Completion Report
(discussed in Section 7.0). After receipt of the sub-slab vapor and indoor air sample analytical
results, H&H will use the most recent version of the DEQ Risk Calculator to evaluate cumulative
vapor intrusion risks under a residential use scenario. The data may also be compared to
commercial use scenarios for the samples collected in the commercial areas.

H&H will consider the VIMS effective if the calculated cumulative risks for the sub-slab vapor
and indoor air samples are within acceptable levels in accordance with DEQ’s Risk Calculator
results. The DEQ acceptable risk levels (see Section 1.2) include:

• cumulative carcinogenic risks less than 1x10-4; and
• non-carcinogenic risk levels below a HI of 1.0.

In the event that calculated cumulative risks are greater than the acceptable risks listed above,
then an evaluation of potential interference of compounds from building material off-gassing for
will be conducted and the data will be presented to DEQ. If it is determined that the sub-slab
vapor and/or indoor air concentrations are from Site contaminants and could lead to unacceptable
vapor intrusion risks to the occupants of the building, confirmation sub-slab soil vapor and
indoor air samples may be collected from the area(s) of concern per discussion with DEQ.
21
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
Further, in this case, an evaluation to potentially convert the system to an active VIMS or other
enhancements to the system will be conducted. If warranted, modifications to the VIMS will be
presented to DEQ for review and approval prior to implementation.

22
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
5.0 VIMS Effectiveness Monitoring
The VIMS is proposed as a passive system which will include vapor extraction through sub-slab
collection piping and solid risers that discharge sub-slab vapors above the roofline. The passive
system will be enhanced with wind-turbine ventilators to promote air exhaust from the sub-slab.
As such, differential pressure monitoring is not anticipated. If the VIMS is converted to an
active system based on pre-occupancy or post-occupancy sub-slab gas and/or indoor air
assessment results, proposed modifications to the VIMP including modifying the VIMS design,
testing and analytical sampling requirements, and details for long-term differential pressure
monitoring across the slab will be submitted to the DEQ Brownfields Redevelopment Section for
approval prior to implementation. The specific electric fans to be used will be selected by the
VIMS design engineer based on the results of the influence testing discussed in Section 4.0.

Post-occupancy sub-slab soil gas and indoor air sampling is proposed to be performed on a semi-
annual basis for a minimum of two years (four events) following initial occupancy of the Site
building. The frequency, amount, and locations of the sub-slab and indoor air sample for the
post-occupancy sampling events may be reduced or modified depending on the pre-occupancy
sampling results, pending DEQ review and approval. A recommendation regarding the post-
occupancy sub-slab soil gas and indoor air sampling will be provided in the VIMS installation
report based on the pre-occupancy sampling results and risk calculations.

The post-occupancy sampling will be conducted using the procedures described in this VIMP.
Further, after each post-occupancy semi-annual sampling event, if the sampling results indicate
consistent or decreasing concentrations within acceptable risk levels, a request to modify or
terminate sampling may be submitted for DEQ approval. No changes to the sampling frequency
or termination of sampling will be implemented until written approval is obtained from DEQ.
The first semi-annual post-occupancy sampling event is anticipated to take place approximately
six months after the start of occupancy of the building, or as otherwise approved by DEQ.

23

6.0 Future Tenants & Building Uses
The proposed redevelopment includes one mixed-use commercial and high-density apartment
building (Building 1) and one high-density apartment building (Building 2). After occupancy of
the Site buildings, VIMS maintenance and upkeep will be the responsibility of the building
owner or property management group. If vapor mitigation components are damaged or need to
be altered for building renovations, the building owners or management will be instructed to
contact appropriate parties to conduct appropriate maintenance. To aid in identification of the
VIMS piping, the piping will be labeled with “Vapor Mitigation – Contact Maintenance”, or
similar language on all accessible piping at intervals of no greater than 10 linear feet. A North
Carolina-licensed Professional Engineer (NC PE) will be contacted to oversee or inspect the
modifications or repair activities, and a report shall be submitted to DEQ detailing the repairs or
alterations.

As part of the standard annual Land Use Restriction Update submittal that will be required as
part of the pending Brownfields Agreement, the building owner or property management group
should complete a visual inspection of the exposed parts of the system including, but not limited
to, the vertical risers and ventilators on the roof and the monitoring points. H&H recommends
annual inspections be documented and kept on record to be provided to DEQ upon request.

24
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/vimp/rev 1/23031-19-060_panoramafalcon_vimp_rev1.doc
7.0 Reporting
A VIMS Installation Completion Report (sealed by a NC PE) documenting installation activities
associated with the VIMS will be submitted to DEQ following confirmation that the mitigation
systems are installed and effectively mitigating potential vapor intrusion risks to building
occupants. The report will include a summary of VIMS installation activities such as
representative photographs and as-built drawings, QA/QC measures, SDSs of materials used in
construction, VIMS effectiveness testing results, and inspection documents. The report will also
include an engineer’s statement as to whether the VIMS was installed in accordance with the
DEQ approved VIMP and is protective of public health as defined in Section 1.0, and as
evidenced by the VIMS inspections performed by the engineer or engineer’s designee, results of
the influence testing, results of the analytical testing, and QA/QC measures as described in this
VIMP. Deviations from the approved design will be provided in the report. Based on the
construction phasing, it is anticipated that a separate report will be submitted for each building.

The pending Notice of Brownfields Property agreement for the Site is anticipated to include
standard land use restrictions that indicate the building(s) shall not be occupied until DEQ
provides written compliance approval for the installation and performance of the VIMS as
documented in the installation report. However, we understand that DEQ may provide
conditional approval with submittal of a data summary package in lieu of the full VIMS
Installation Completion Report if warranted based on timing of the proposed building occupancy
date and report review times. No occupancy of the building can occur without prior written
approval of DEQ.

After each semi-annual post-occupancy sub-slab soil gas and indoor air sampling event, a report
will be submitted to DEQ to document the sampling activities and results with recommendations
for future post-occupancy sampling (Section 5.0). The first post-occupancy semi-annual
monitoring event is anticipated to be conducted approximately 6 months after the initial
occupancy of the building, or as otherwise approved by DEQ based on the data results and
timing of the occupancy of the Site buildings.

VAPORBLOCK® PLUS™VBP20
PRODUCT DESCRIPTION
VaporBlock® Plus™ is a seven-layer co-extruded barrier
made using high quality virgin-grade polyethylene and
EVOH resins to provide unmatched impact strength as well
as superior resistance to gas and moisture transmission.
VaporBlock® Plus™ 20 is more than 100 times less permeable
than typical high-performance polyethylene vapor retarders
against Methane, Radon, and other harmful VOCs. Tested and
verified for unsurpassed protection against BTEX, HS, TCE, PCE,
methane, radon, other toxic chemicals and odors.
VaporBlock® Plus™ 20 multi-layer gas barrier is manufactured
with the latest EVOH barrier technology to mitigate hazardous
vapor intrusion from damaging indoor air quality, and the safety
and health of building occupants. VBP20 is one of the most
effective underslab gas barriers in the building industry today
far exceeding ASTM E-1745 (Plastic Water Vapor Retarders
Used in Contact with Soil or Granular Fill Under Concrete Slabs)
Class A, B and C requirements. Available in a 20 (Class A) mil
thicknesses designed to meet the most stringent requirements.
VaporBlock® Plus™ 20 is produced within the strict guidelines
of our ISO 9001 Certified Management System.
PRODUCT USE
VaporBlock® Plus™ 20 resists gas and moisture migration
into the building envelop when properly installed to provide
protection from toxic/harmful chemicals. It can be installed as
part of a passive or active control system extending across the
entire building including floors, walls and crawl spaces. When
installed as a passive system it is recommended to also include
a ventilated system with sump(s) that could be converted to an
active control system with properly designed ventilation fans.
VaporBlock® Plus™ 20 works to protect your flooring and
other moisture-sensitive furnishings in the building’s interior
from moisture and water vapor migration, greatly reducing
condensation, mold and degradation.
SIZE & PACKAGING
VaporBlock® Plus™ 20 is available in 10’ x 150’ rolls to
maximize coverage. All rolls are folded on heavy-duty cores
for ease in handling and installation. Other custom sizes
with factory welded seams are available based on minimum
volume requirements. Installation instructions and ASTM E-1745
classifications accompany each roll.

1.4. Seal around all plumbing, conduit, support columns or other penetrations that come through the VaporBlock® Plus™ membrane.
1.4a. Method 1: Pipes four inches or smaller can be sealed with Raven VaporBoot Plus preformed pipe boots. VaporBoot Plus preformed pipe boots are formed in steps for 1”, 2”, 3” and 4” PVC pipe or IPS size and are sold in units of 12 per box (Fig. 3 & 5).
Pipe boots may also be fabricated from excess VaporBlock® Plus™ membrane (Fig. 4 & 6) and sealed with VaporBoot Tape or VaporSeal™ Tape (sold separately).
1.4b. Method 2: To fabricate pipe boots from VaporBlock® Plus™ excess material (see Fig. 4 & 6 for A-F):
A) Cut a square large enough to overlap 12” in all directions.
B) Mark where to cut opening on the center of the square and cut four to eight slices about 3/8” less than the diameter of the pipe.
C) Force the square over the pipe leaving the tightly stretched cut area around the bottom of the pipe with approximately a 1/2” of the boot material running vertically up the pipe. (no more than a 1/2” of stretched boot material is recommended)
D) Once boot is positioned, seal the perimeter to the membrane by applying 2-sided Raven Butyl Seal Tape in between the two layers. Secure boot down firmly over the membrane taking care not to have any large folds or creases.
E) Use VaporBoot Tape or VaporSeal™ Tape to secure the boot to the
pipe.
VaporBoot Tape (option) – fold tape in half lengthwise, remove half of the release liner and wrap around the pipe allowing 1” extra for overlap sealing. Peel off the second half of the release liner and work the tape outward gradually forming a complete seal.
VaporSeal™ Tape (option) - Tape completely around pipe overlapping the VaporBlock® Plus™ square to create a tight seal against the pipe.
F) Complete the process by taping over the boot perimeter edge with VaporSeal™ Tape to create a monolithic membrane between the surface of the slab and gas/moisture sources below and at the slab perimeter. (Fig. 4 & 6)

1.6. POUR-N-SEAL™ method of sealing side-by-side multiple penetrations (option 2);
A) Install the vapor barrier as closely as possible to pipe penetrations to minimize the amount of POUR-N-SEAL™ necessary to seal around all penetrations.
B) Once barrier is in place, remove soil or other particles with a dry cloth or a fine broom to allow for improved adhesion to the POUR-N-SEAL™ liquid.
C) Create a dam around the penetration area approximately 2” away from the pipe or other vertical penetrations by removing the release liner from the back of a 1” weather stripping foam and adhere to the vapor barrier. Form a complete circle to contain the POUR-N-SEAL™ materials (Fig. 11).
D) Once mixed, pour contents around the pipe penetrations. If needed, a brush or a flat wooden stick can be used to direct the sealant completely around penetrations creating a complete seal (Fig. 12-13).
E) DO NOT leave excess POUR-N-SEAL™ in plastic container for longer than the time it takes to pour sealant.

VAPORBLOCK® PLUS™ REPAIR INSTRUCTIONS
1.7. Proper installation requires all holes and openings are repaired prior
to placing concrete. When patching small holes, simply cut a 12” long
piece of 12” wide VaporSeal™ tape. Remove release liner and center
over the opening. Apply pressure to create a seal (Fig. 14-15).
1.8. When installing VaporBlock® Plus™ around pipe penetrations,
vertical columns, electrical ducts and other obstructions, you will
find it necessary to cut it to the nearest outside edge. This cut can
be easily sealed with 12” wide VaporSeal™ tape, by simply centering
it over the cut, 6” on either side. Once the tape is placed correctly,
apply pressure to assure a complete seal (Fig. 16).
Reminder Note: All holes or penetrations through the membrane will need
to be patched with 12” VaporSeal™ Tape.
Fig. 14
Page 4 of 5
Fig. 15
2.1. When installing reinforcing steel and utilities, in addition to the
placement of concrete, take precaution to protect VaporBlock®
Plus™. Carelessness during installation can damage the most
puncture–resistant membrane. Sheets of plywood cushioned with
geotextile fabric temporarily placed on VaporBlock® Plus™ provide
for additional protection in high traffic areas including concrete
buggies.
2.2. Use only brick-type or chair-type reinforcing bar supports to protect
VaporBlock® Plus™ from puncture.
2.3. Avoid driving stakes through VaporBlock® Plus™. If this cannot be
avoided, each individual hole must be repaired per section 1.7.
2.4. To avoid penetrating VaporBlock® Plus™ when installing screed
supports, utilize non-penetrating support, such as the Mako®
Screed Support System (Fig. 17). Avoid driving stakes through
VaporBlock® Plus™. If this cannot be avoided, each individual hole
must be repaired per figures 14-15.
2.5. If a cushion or blotter layer is required in the design between
VaporBlock® Plus™ and the slab, additional care should be given if
sharp crushed rock is used. Washed rock will provide less chance of
damage during placement. Care must be taken to protect blotter layer
from precipitation before concrete is placed.

INSTALLATIONINSTRUCTIONS
DRAGO® WRAP
VAPOR INTRUSION BARRIER
Engineered protection to create a healthy built environment.
2. Unroll Drago Wrap over the area where the slab is to be placed.
Drago Wrap should completely cover the concrete placement
area. All joints/seams should be overlapped a minimum of
12 inches and taped using Drago® Tape. (Fig. 1). If additional
protection is needed, install DragoTack™ Tape in between the
overlapped seam in combination with Drago Tape on top of the
seam.
NOTE: The area of adhesion should be free from dust, dirt, moisture,
and frost to allow maximum adhesion of the pressure-sensitive tape. Ensure that all seams are taped with applied pressure to allow for
maximum and continuous adhesion of the pressure-sensitive Drago Tape. Adhesives should be installed above 40°F. In temperatures
below 40°F, take extra care to remove moisture/frost from the area
of adhesion.
3. ASTM E1643 requires sealing the perimeter of the slab. Extend
vapor retarder over footings and seal to foundation wall or
grade beam at an elevation consistent with the top of the slab
or terminate at impediments such as waterstops or dowels.
Consult the structural and environmental engineer of record
before proceeding.
IMPORTANT: Please read these installation instructions completely, prior to beginning any Drago Wrap installation. The following installation
instructions are generally based on ASTM E1643 – Standard Practice for Selection, Design, Installation, and Inspection of Water Vapor Retarders
Used in Contact with Earth or Granular Fill Under Concrete Slabs. There are specific instructions in this document that go beyond what is stated in
ASTM E1643 to take into account vapor intrusion mitigation. If project specifications call for compliance with ASTM E1643, then be sure to review
the specific installation sections outlined in the standard along with the techniques referenced in these instructions.

MULTIPLE PIPE PENETRATION SEALING: (Fig. 5)
NOTE: Multiple pipe penetrations in close proximity may be most efficiently sealed using Drago Wrap, Drago
Sealant, and Drago Sealant Form for ease of installation.
a. Cut a hole in Drago Wrap such that the membrane fits over and around the base of the pipes as closely as
possible, ensuring that it is flush with the base of the penetrations.
b. Install Drago Sealant Form continuously around the entire perimeter of the group of penetrations and at least
1 inch beyond the terminating edge of Drago Wrap.
c. Pour Drago Sealant inside of Drago Sealant Form to create a seal around the penetrations.
d. If the void space between Drago Wrap and the penetrations is not minimized and/or the base course allows for
too much drainage of sealant, a second coat of Drago Sealant may need to be poured after the first application
has cured.
IMPORTANT: AN INSTALLATION COMPLETED PER THESE INSTRUCTIONS SHOULD CREATE A MONOLITHIC MEMBRANE
BETWEEN ALL INTERIOR INTRUSION PATHWAYS AND VAPOR SOURCES BELOW THE SLAB AS WELL AS AT THE SLAB
PERIMETER. THE UNDERLYING SUBBASE SHOULD NOT BE VISIBLE IN ANY AREA WHERE CONCRETE WILL BE PLACED. IF
REQUIRED BY THE DESIGN ENGINEER, ADDITIONAL INSTALLATION VALIDATION CAN BE DONE THROUGH SMOKE TESTING.

MADE IN THE USA
SOIL GAS COLLECTOR MAT FOR RADON READY NEW CONSTRUCTION
According to the US EPA’s model stan-dards for radon control systems in new building construction, a means for col-lecting soil gas should be installed be-neath the slab.
More and more mitigators and buildiers are using PDS’ soil gas collector mat because its installation does not entail any special coordination with plumb-ers or other site contractors. Low pro-file mat saves time as it removes the need for trenching. Just lay radon mat down around the inside perimeter of the foundation, secure it with spikes or landscaping staples, and pour the con-crete.
SGC mat is superior to other mat sys-tems because of its thickness and it has a geotextile fabric cloth surround-ing the entire mat material. This fea-ture eliminates the need to lay a plas-tic barrier or sheet on top of the mat to protect the matrix. Using plastic sheeting can cause concrete cracking due to differential dewatering. The full fabric design greatly enhances both the installation as well as the quality of the concrete slab. When SGC mat is in-stalled below the slab, you’re providing an airspace that intercepts radon--and other soil gases and vapors--before it seeps into the building through the slab. SGC mat also works well as a soil gas collector beneath crawlspace bar-rier due to its low-profile.
WHY & HOW IT WORKS
The matting is a one inch high by twelve inch wide matrix enveloped in a geotextile filter fabric. 90% of the geomatrix is airspace, which means soil gas has room to move to the col-lection point. This creates incredible pressure field extension for post con-struction system activation. The mat can support concrete without com-pressing, yet is extremely lightweight and easy to handle.
This system allows for radon to flow through the filter fabric and into the airspace. The airspace does not clog because the filter fabric retains the underlying gravel and soil. The natural airflow through the mat then channels the radon to the T riser to pipe connec-tion. From there, hazardous gas can be vented safely through the roof of the building.
Another key element of a soil gas col-lection system is attaching the 4” riser to the mat, such that airflow is not restricted at this critical juncture. The soil gas T riser is unique as it has three ports, two redundant mat entries and one PVC connection to outside air. This unique fitting connects all three sides without special connections or fittings. common duct tape and caulk does the trick. 2

INSTALLATION INSTRUCTIONS
1. Begin work on the sub grade (soil or gravel) after the final preparation and
before the concrete is poured. Start with T-Riser(s) and work out to ensure
smooth mat placement. Position the T-Riser(s) in appropriate location(s) and
nail down with a 12” steel nail (T Nail) through precut center hole.
2. Slide mat into flat openings on either end of T-riser with a portion of the fab-
ric around the outside. Tape the fabric to the outside of the T-Riser with duct
tape and staple mat to the ground with landscape staples to ensure soil contact
remains during pour stage.
3. Mat is typically laid out in a rectangular loop in the largest area with branch-
es or legs into smaller areas (FREE plan design at www.radonmat.com). There
is no need to trench the mat. Roll out the SGC mat, smooth it onto the ground.
To avoid wrinkles and buckling, work away from the risers, stapling to the
ground as you go. The mat should be stapled every three to four feet, in addi-
ton to corners, tee junctions & ends.
5. Corners are constructed by peeling back the filter fabric, cutting two ends
of the matrix at 45 degree angles and butting (or overlapping: no more than
1/2”) the matrix together. Pull the filter fabric back and tape into place. Staple
across the joint of the matrix and each leg of the corner. Use a minimum of
four staples at each corner-- two across the joint and one on each leg.
6. The tees for branches and legs are constructed by slitting the fabric of the
main loop at the location desired. Cut the fabric of the branch at the edges and
expose two inces of the matrix. Cut off the exposed matrix and but the ma-
trix of the branch (or overlap 1/2”)to the matrix of the main loop. Pull the flter
fabric of the branch back over the main loop and tape into place. Staple across
joint of the matrix with two staples and one each on the branch and main loop.
Use a minimum of four staples at each tee, two across the joint and one on
each loop and branch.

7. All openings in the fabric at joints, tee’s, and ends of branches should be
taped to keep out concrete.
8. Stub up a few feet of 4” schedule 40 PVC* from all T risers before pour (or
cover T riser with duct tape). Seal with polyurethene caulk and screws. This
ensures no concrete aggregate enters the riser during slab pour. Be sure to
label “CAUTION RADON REDUCTION SYSTEM” on all pipe. *(6” PVC may be
substituted--for large multifamily projects. Simply cut T riser 4” insert away to
reveal 6” insert).
9. When the building is ready for the vent pipe to be installed above the slab,
fit to pre-stubbed PVC with PVC straight connect. If PVC was not preset, cut
duct tape from riser and insert 4” PVC pipe now. Seal with polyurethene caulk
and secure with screws. Always label “CAUTION RADON REDUCTION SYSTEM”
to avoid confusion on site and for the building occupants.
NOTE: The openings in the riser are laid out at 180 degrees to accomodate
straight runs of mat. However, if the riser is to be placed in a corner, which is
not uncommon, the front of the T can be cut and the SGC mat inserted into
the new opening. The side of the T that is unused should be sealed with tape.
This creates a 90 degree T which will allow corner placement for the riser. Mat
should always enter the T riser from at least two directions and exhaust to pipe
vertically.

MAKING CORNERS AND SPLICES
The mat should be routed around the inside perimeter of the foundation. This
will require occasional corner junctions. Furthermore, splices will have to be
made to join two lengths of mat together. Corners and splices are very easy to
make, and do not require any special fittings. Cut back the filter fabric to reveal
the core material. In the case of a splice, merely overlap the core by at least
one corrugation, replace the cloth, and tape it. Use two landscape staples to
hold the splice in place. In the case of a corner, peel back geotextile fabric and
slice the core of the two adjoining legs at 45 degree angles which mirror each
other; overlap the edges by one corrugation; return grey geotextile fabric, tape
and staple the corner together.

CONNECTING THE MAT TO THE
T RISER
A convenient T-riser with dual entry al-
lows for either end of the loop of mat
to be secured to the riser. Slide the mat
into each end of the riser and tape the
edge to prevent wet concrete from en-
tering. Cap the riser to ensure no con-
crete enters. T Riser caps can be pur-
chased in lieu of duct tape. A prestub of
PVC pipe can also serve the same pur-
pose. See steps 8-9 above.
***Due to high product demand, several T riser de-signs have been tested and approved for sale. Your
riser may look different than the one pictured here,
however its function is the same. Ensure you stub
up the PVC pipe and seal all openings with tape so
that concrete does not enter during the pour. Se-cure mat to the ground with staples so riser does
not float.

POURING CONCRETE
The filter fabric that comes sewn around the soil gas collector prevents the wet
concrete from entering the mat and reducing its air collection capacity. The
only precaution that needs to be taken is that the fabric is duct taped closed at
seams of splices and corner to sufficiently keep the uncured concrete from en-
tering.
The mat also needs to be secured to the soil with landscape staples to prevent
the concrete from lifting off the soil while it is being applied. Re-enforcing bars
and wire can be laid on top of the mat.
Note: the mat is strong enough (4,300 psf) to withstand concrete workers and
their wheel barrows.
