Vapor Intrusion Mitigation Plan – Revision 1 Kaiser Fluids Tech II 530 East Sugar Creek Road Charlotte, North Carolina Brownfields Project No. 20026-16-060 H&H Job No. T&U-004 1.0 Introduction

On behalf of Trailhead 530 Owner, LLC (the Prospective Developer or PD), Hart & Hickman,
PC (H&H) has prepared this Vapor Intrusion Mitigation Plan (VIMP) for a portion of the former
Kaiser Fluids Tech II Brownfields property (Brownfields Project No. 20026-16-060) located at
530 E. Sugar Creek Road in Charlotte, Mecklenburg County, North Carolina. The Brownfields
Property is comprised of two contiguous parcels of land (Parcel ID Numbers 09107104 and
09107204) bisected by Raleigh Street, that total approximately 8.126 acres. The northern parcel
(530 E. Sugar Creek Road; former Kaiser Fluid Technologies) consists of vacant land with the
exception of a former building slab and paved parking lot. The southern parcel (4100 Raleigh
Street; former Henkel Chemical) is being redeveloped for various commercial purposes. This
VIMP outlines vapor intrusion mitigation system (VIMS) measures for the northern 4.5-acre
parcel (530 E. Sugar Creek Road) of the Brownfields Property only (Site). A Site location map
is provided as Figure 1, and the Site and surrounding area are shown in Figure 2.

The Site appears to have been developed for industrial purposes as early as 1956 with an
approximately 67,400 square foot (sq ft) industrial building. From the mid-1950s to early 2000s,
the Site was occupied by Ronson Hydraulics Unit Corporation and Kaiser Fluid Technologies
which manufactured hydraulic fluid control systems for the aerospace industry. Since the early
2000s, the Site building was primarily vacant or used for general storage purposes. The Site
building was razed in November and December 2017 and the concrete building slab was left in-
place. Remaining portions of the Site have consisted of asphalt paved parking areas and access
drives since that time. The Site is currently vacant and is periodically used for truck and trailer
parking.

To address potential environmental concerns associated with the Site, the previous property
owner elected to enter the Site into the DEQ Brownfields Program as documented in the Notice
of Brownfields Property (Brownfields Agreement) recorded on July 15, 2021. The PD will
acquire the property subject to the Brownfields Agreement. Preliminary Site redevelopment
plans indicate that the Site will be developed with one high-density residential apartment
building and a potential future office building. The VIMS design (Attachment A) documented
herein applies to the proposed residential apartment building only.

1.1 Background

In October 2018, H&H conducted Brownfields assessment activities at the Site to evaluate the
potential for impact attributable to historical industrial uses at the Brownfields property and on
nearby off-Site properties. The Brownfields assessment activities included collection of
groundwater, soil, soil gas, sub-slab vapor, and concrete slab samples and are summarized in the
Brownfields Assessment Report prepared by H&H and dated December 21, 2018 and in the
Environmental Management Plan (EMP) dated October 26, 2022. A brief summary of the
sampling activities and results pertinent to potential vapor intrusion at the residential
development are provided below.

Soil Sampling
In October 2018, H&H collected eleven (11) soil samples for laboratory analysis to evaluate the
potential for impacts in areas of the Brownfields property planned for redevelopment with a
residential building. Soil sampling results indicate that no volatile organic compounds (VOCs)
were detected in the soil samples collected from the Site at concentrations exceeding the DEQ
Residential Preliminary Soil Remediation Goals (PSRGs). Further, the metal compound
mercury was not detected above its Residential PSRG in any of the soil samples.

Groundwater Sampling
In October 2018, H&H installed and sampled four (4) temporary groundwater monitoring wells
(HHTMW-1 through HHTMW-4) at the Site to further evaluate Site impacts. Results of the
groundwater assessment activities identified a concentration of chromium (total) in HHTMW-2
3
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
(located on the western portion of the Site) in exceedance of the DEQ 2L Groundwater Quality
Standard (2L Standard). Laboratory analytical results also identified concentrations of 1,4-
dioxane and vinyl chloride above their respective 2L Standards in a groundwater sample
collected in the southeastern portion of the Site (HHTMW-4). Additionally, trichloroethylene
(TCE) was detected at an estimated concentration (laboratory J-flag value) of 1.4 J micrograms
per liter (µg/L) in HHTMW-4, which is above the Residential Groundwater Vapor Intrusion
Screening Level (GWSL) but below the 2L Standard. Several other VOCs were detected in the
groundwater samples at concentrations above laboratory reporting limits but below the 2L
Standards and GWSLs.

Soil Gas Sampling
In October 2018, H&H collected six (6) exterior soil gas samples (HHSG-1 though HHSG-6)
from the Site. Results of the sampling activities identified benzene, ethylbenzene, total xylenes,
and 1,3-butadiene in the soil gas samples collected from the Site at concentrations above the
DEQ Residential Soil Gas Screening Levels (SGSLs) but below the Non-Residential SGSLs.
1,2-Dibromoethane (EDB) was detected in soil gas sample HHSG-5 (collected from the western
portion of the Site) at a concentration above the Non-Residential SGSL. Additionally, TCE was
detected in soil gas sample HHSG-3 (collected from the northwestern portion of the Site) at a
concentration of 24 micrograms per cubic meter (µg/m3), which is above the Residential SGSL
of 14 µg/m3.

Sub-Slab Vapor Sampling
In October 2018, H&H collected four (4) sub-slab vapor samples (HHSS-1 through HHSS-4)
from the Site to further evaluate the potential for structural vapor intrusion into the proposed
residential apartment building. Sub-slab vapor sample laboratory analytical results indicate that
EDB was detected at concentrations of 15 µg/m3 and 2.9 µg/m3 in HHSS-1 and HHSS-3,
respectively. These concentrations exceed the Residential SGSL of 1.6 µg/m3. Additionally,
results indicate that TCE was detected in each of the four sub-slab samples collected from the
Site. TCE was detected at concentrations of 66.6 µg/m3 and 37 µg/m3 in sub-slab vapor samples
HHSS-1 and HHSS-2, respectively, which exceed the Residential SGSL of 14 µg/m3. The
laboratory analytical results indicate TCE was also detected at a concentration of 493 µg/m3 in
4
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
HHSS-4 (collected from the southern portion of the Site), which exceeds the Non-Residential
SGSL of 180 µg/m3. No other VOCs were detected in the sub-slab vapor samples at
concentrations above SGSLs.

1.2 Vapor Intrusion Evaluation
To further evaluate the detected VOCs, H&H input the concentrations of the compounds
detected in each exterior soil gas and sub-slab vapor sample in the DEQ Risk Calculator
(February 2018 Version). The DEQ DWM Vapor Intrusion SGSLs used for comparison to the
laboratory analytical results are conservative and based upon a Target Cancer Risk (TCR) of
1 x 10-6 for potential carcinogenic effects and a hazard quotient (HQ) of 0.2 for potential
noncarcinogenic effects. Typically, vapor intrusion mitigation for a building is not considered
unless the calculated cumulative lifetime incremental carcinogenic risk (LICR) is 1.0 x 10-4 or
greater for potential carcinogenic risks and/or the calculated cumulative hazard index (HI) is 1.0
or greater for potential non-carcinogenic risks. Copies of risk calculator summary sheets are
included in Attachment B.

As summarized in the Brownfields Assessment Report, DEQ risk calculators were analyzed for a
residential and non-residential use worker scenario for each exterior soil gas and sub-slab vapor
sample collected during the 2018 activities. The DEQ risk calculator results for the soil gas to
indoor air pathway indicate that the cumulative LICR and HI are above the DEQ acceptable
thresholds of 1.0 x 10-4 and 1.0, respectively, for sub-slab vapor samples HHSS-1 and exterior
soil gas sample HHSG-4 under a residential land use scenario. The risk calculations also
indicated the cumulative HI is above the DEQ acceptable threshold in sub-slab vapor sample
HHSS-4 and exterior soil gas sample HHSG-1, but the calculated carcinogenic risk is acceptable
for these samples. Risk calculator results for the soil gas to indoor air pathway for the sub-slab
and exterior soil gas samples did not indicate a carcinogenic and/or non-carcinogenic risk level
above the DEQ risk threshold under a non-residential land use scenario.

The soil gas to indoor air risk calculator results indicate that there is a potential vapor intrusion
risk at unacceptable levels for the planned residential apartment building. Therefore, the PD will

install a vapor mitigation system for occupiable ground-level components of the proposed
apartment building to mitigate the potential vapor intrusion risk in the Site building in
accordance with land use restriction (LUR) g(ii) of the Notice of Brownfields Property. Please
note, as summarized in the Brownfields Agreement, a Declaration of Perpetual Land Use
Restrictions (DPLUR) dated February 8, 2008 was previously recorded for this property which
includes a LUR regarding mechanical ventilation requirements. The PD is currently in
discussion with the DEQ Inactive Hazardous Sites Branch (IHSB) Program regarding the
requirement for mechanical ventilation as it relates to open-air spaces, like the parking garage
(see Section 2.0).

Engineer’s Certification
According to the DEQ 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 condition in the
Brownfields Agreement for the Site. 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
DEQ 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 (VIMS) detailed herein is designed to mitigate intrusion
of subsurface vapors into the subject building 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 previous assessment sampling results (Section 1) and risk calculations indicate that a VIMS
is warranted for the proposed residential multi-family building due to elevated soil-gas vapor
risks calculations. The VIMS design drawings are included in Attachment A as Sheets VM-1A,
VM-1B, VM-2, VM-2A, and VM-3 (dated February 20, 2023) and will be used to guide
construction of the VIMS. To reduce the potential for structural vapor intrusion, the VIMS will
operate as a passive sub-slab venting system that discharges vapors outside of the building and.
The VIMS includes a network of horizontal sub-slab vapor collection network and vertical
above-slab riser piping connected to wind-driven turbine ventilators installed above the building
roof to enhance the passive system along with a VOC-rated vapor barrier installed below the
building slab.

The proposed development will consist of one five-story high-density residential apartment
building. The building will consist of a total enclosed occupiable ground floor space of
approximately 67,800 sq ft. The ground floor (Level 1) of the proposed building will be
constructed on grade and will consist of residences, lobbies, amenity spaces, and
mechanical/utility rooms. Levels 2 through 5 will consists of residences, amenity spaces, and
mechanical rooms. The building will contain a flat roof with mechanical equipment that is not
accessible to tenants. No pour back retail areas are proposed for the residential building. The
ground floor of the building will be constructed with thickened slab below load bearing walls.
Each interior thickened slab is proposed to contain a stone layer beneath that connects with the
sub-slab stone layer (Section 2.1).

The attached parking garage will also be five stories and is designed as a naturally ventilated
garage; thus it is considered to be an open-air space. There are no living spaces within or above
the parking garage. There are several utility/amenity rooms on the ground floor of the garage
including electrical, trash, and pump rooms. While these areas aren’t occupiable spaces, vapor
barrier (Section 2.1) will also be installed below these spaces as a conservative measure. The
garage also contains a bike storage room and an elevator and stairwell. These areas will be
frequented by residential tenants and are adjacent to the living spaces. Therefore, these areas
8
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
will be incorporated into the VIMS as depicted on the design drawings. Further, there is a
maintenance room located within the garage that will only be used by commercial workers. The
maintenance room will contain mechanical exhaust ventilation with an outside air intake. The
previous assessment data (Section 1.0) indicated there was acceptable commercial vapor
intrusion risk in the proposed footprint of the parking garage. However, as an additional
precaution, vapor barrier will also be installed below the maintenance room.
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
design engineer certifying the VIMP) below the concrete slab of the building and below the
interior thickened slabs. A vapor barrier (vapor liner) with spray-applied seams will be installed
by a manufacturer-certified installer above the base course stone layer and directly beneath the
slab. The vapor liner 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 network will be installed
within the base course stone layer below the ground floor slabs prior to placement of the vapor
liner. The horizontal vapor collection network is discussed further in Section 2.2. below. The
piping layouts are shown on the VIMS design drawings (Attachment A).

The vapor liner will consist of VI-20™ vapor intrusion barrier manufactured by CETCO. VI-
20™ is a 20-mil polyethylene-EVOH geomembrane designed to prevent migration of volatile
organic compounds (VOCs). The exterior edges of the VI-20™ will be sealed to concrete
surfaces utilizing spray-applied Liquid Boot® barrier at a thickness of 60-mil, or as otherwise
directed by CETCO. Seams within the building footprint will have a minimum 6-inch overlap
and will also be sealed with a 60-mil thickness of Liquid Boot™. Small puncture holes will be
sealed with Liquid Boot™, and larger holes, tears, or damage will be repaired using a patch that
overlaps the damaged area and then will be sprayed along the seams with Liquid Boot™. In
areas where utility penetrations (i.e., piping, ducts, etc.) are present, a minimum of 60-mil of
9
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
Liquid Boot™ will be used to form an airtight seal around the penetrations. Locations where
Liquid Boot™ is applied at penetration banks will be documented during the field inspections
and noted on the as-built drawings.

To evaluate the vapor barrier installation and Liquid Boot™ thickness, the installation process
will include measuring the Liquid Boot™ thickness during application and smoke testing,
completed by the manufacturer-certified installer, to confirm the VI-20™ system is free of leaks.
If leaks are identified during smoke testing, the identified areas will be repaired with a patch
and/or additional spray-applied sealant. After installation, a layer of UltraShield™ G-Series will
be placed above the vapor barrier for protective cover prior to the concrete pour. Technical
specifications and installation instructions obtained from CETCO for the VI-20™ vapor barrier
and associated accessories are provided in Attachment C.

Please note that an equivalent vapor barrier approved by the design engineer which meets the
criteria specified on Sheet VM-3 may also be used by the installation contractor, such as Geo-
Seal® EV20 manufactured by EPRO or VaporBlock® Plus 20 (VBP20) manufactured by Raven
Industries. Note, for enclosed areas within the parking garage footprint the use of VBP20 is
permitted. If an alternate equivalent vapor barrier is selected and approved by the design
engineer, DEQ will be notified of the alternate vapor barrier prior to installation.

The vapor liners 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 liner
manufacturer recommends select sealing agents (spray-applied, mastics, tapes, etc.) for their
vapor barrier product. In accordance with manufacturer installation instructions, alternative
vapor liner products that are not approved by the manufacturers for sealing will not be used,
unless approved by the design engineer and specific manufacturer.

2.2 Horizontal Collection Piping and Vertical Riser Piping
Passive sub-slab venting will be accomplished using a GeoVent™ sub-slab gas venting system
connected at footings with 3-inch diameter Schedule 40 (SCH 40) poly-vinyl chloride (PVC)
10
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
horizontal collection piping, 3-inch diameter SCH 40 PVC riser piping, and syphon ventilators
which will collect vapor from beneath the floor slab and discharge above the building roofline.
GeoVent™ is an approximately 1-inch-thick collection system designed to reduce gas
concentrations below the slab and provide venting efficiency for the vertical risers. The sub-slab
layout is shown in Sheets VM-1A and VM-1B and cross-section details and system
specifications are shown in Sheets VM-2, VM-2A, and VM-3 (Attachment A). Note that a
minimum 4-inch layer of base course gravel must be installed in areas around GeoVent™ with a
minimum one inch above and below the GeoVent™ and a minimum of 4 inches of gravel in the
areas without GeoVent™. Also note that a minimum 4-inch uniform layer of base course gravel
(#57 stone) is to proposed to be installed below all thickened slabs within the building footprint,
per the structural plans. Product specifications for the GeoVent™ sub-slab venting system are
provided in Attachment C.

If an alternative vapor barrier is installed, slotted or perforated 3-inch diameter SCH 40 PVC
horizontal piping may be used for sub-slab vapor collection piping with solid sections of PVC
pipe installed in locations of footings and thickened slab crossings. Product specifications for the
slotted SCH 40 PVC 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 approved alternative by design
engineer certifying the VIMP) 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 are not 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.

11
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
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 electric (active) fan be warranted
in the future.

2.3 Monitoring Points

Monitoring points constructed with 2-inch diameter SCH 40 PVC and a PVC termination screen
(see Attachment C) or an open-ended pipe 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 vapor samples for laboratory analysis. The monitoring point locations are
shown on the VIMS design drawings (Attachment A).

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, including monitoring
points within stairwells. To limit disturbance to residents during future monitoring events, the
majority of the monitoring point access ports will be located in stairwells, hallways, mechanical
rooms, or amenity spaces and protected by a floor clean-out or wall panel style cover. The
monitoring points in the stairwells will generally be placed below stair landings to avoid being
placed in the main walkway/access routes for the building tenants. Several monitoring points
will be connected to extended sub-slab horizontal pipes which place the intakes of the
12
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
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 floor
cleanout covers are provided in Attachment C.

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
if monitoring points are notably relocated in relation to 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.

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 must 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. To minimize potential preferential pathways through the slab, contractors
shall not use hollow piping to support utilities in preparation for concrete pours.

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 shall 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
13

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 the VIMS installation. The components that require inspection are outlined
below:
(1) Inspection of the base course stone layer, sub-slab piping layout, and monitoring points
prior to installing the vapor barrier;
(2) Inspection of the vapor barrier prior to pouring concrete or backfilling applicable sub-
grade vertical walls and elevator pits;
(3) Inspection of above-grade vertical riser piping; and
(4) Inspection of riser pipe connections 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 be instructed to avoid the use of hollow conduits to support utilities in
preparation for the concrete pours. Contractors will be required to remove or adequately cap
hollow conduits observed during field inspections. The contractor shall notify the engineer
certifying the VIMP, or designee, with a minimum notice of two (2) business days prior to a
planned inspection, and H&H will provide a subsequent notice of two (2) business days 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 liner, and completion of concrete slab pours.

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. A pressure differential resulting in depressurization below the slab of
at least 4 pascals (approximately 0.016 inches of water column) at remote distances from riser
location in each VIMS treatment area may be considered sufficient evidence of 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. H&H will notify DEQ with
a minimum notice of two (2) business days prior to a planned influence testing event. 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 Analytical Sampling

As described in Section 1.0, TCE, a primary contaminant of concern, was detected in exterior
soil gas and sub-slab vapor samples collected at the Site in exceedance of Residential and/or
Industrial/Commercial SGSLs. Following VIMS installation, but prior to occupancy of the
building, analytical vapor sampling (which will include the collection of concurrent sub-slab soil
gas samples and indoor air samples) will be conducted across the proposed Site building
footprint to evaluate the potential for structural vapor intrusion.
16
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
Sub-Slab Soil Gas
The sub-slab soil gas samples will be collected from select monitoring points in locations
generally separated by slab footings and at the furthest extents of the VIMS treatment areas.
Sub-slab soil gas sample analytical results will be used to evaluate potential risks to future
occupants of the building. A total of nine sub-slab vapor samples are proposed across the
building footprint at representative monitoring point locations MP-1, MP-4, MP-7, MP-10, MP-
12, MP-16, MP-18, MP-21, MP-23. As 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 purposes 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
17
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
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.

The samples will be submitted to a qualified laboratory under standard chain of custody
protocols for analysis of full-list VOCs, including naphthalene, by EPA Method TO-15. The
analytical laboratory will be instructed to report vacuum measurements as received at the lab and
J-flag concentrations 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.

Indoor Air Sampling
To further evaluate the effectiveness of the VIMS, eight indoor air samples (IAS-1 through IAS-
8) will be collected concurrently with the sub-slab vapor samples (within an approximate 48-hr
period) as a conservative measure within select ground floor areas. Indoor air sampling activities
will be conducted concurrently with sub-slab soil gas sampling and in accordance with the DWM
VI Guidance. To prevent interference of soil gas vapors with the indoor air samples, the indoor
air samples will be collected prior to the sub-slab soil gas samples. Proposed indoor air sampling
locations are depicted on sheets VM-1A and VM-1B of Attachment A.

The building is 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 fully enclosed building including a minimum of
two weeks following completion of the risers and ventilators (if warranted), 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 HVAC system is not running.” Furthermore,
HVAC equipment is typically not able to be activated until approximately a few weeks prior to
occupancy 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
18
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
allow for time to conduct the pre-occupancy sampling and reporting as required in this Plan prior
to occupancy. 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 HVAC is
operational prior to finishing activities, the pre-occupancy indoor air samples may be collected
with the HVAC operating. The type and operation of the HVAC system will be recorded during
the sampling event and reported to DEQ in the Installation Completion Report.

The indoor air sample and background air samples will be collected using individually-certified
6-liter stainless steel Summa canisters connected to in-line flow controllers equipped with a
vacuum gauge. The flow controllers will be set by the laboratory to allow the samples to be
collected over an approximately 24-hour period for a residential use scenario. A laboratory-
supplied 3-foot long 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.

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 a
qualified laboratory for analysis of select list VOCs by EPA Method TO-15, including
naphthalene. The select list will include all VOC compounds detected in Site media (soil-gas,
sub-slab vapor, soil, and groundwater) that are part of the EPA Method TO-15 list. If additional
compounds are detected in the sub-slab vapor samples that weren’t detected previously on the
19
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
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 method detection limits 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 paint, caulk, carpet, mastics, 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 requested to
provide SDSs for materials used during construction which will be submitted to DEQ, if needed
to further evaluate sub-slab and indoor air data. Contractors will be instructed not to use
materials which contain PCE or TCE. They will also be instructed to not use products with the
daughter products of PCE/TCE, including 1,2-cis-dichloroethene, 1,2-trans-dichloroethene, and
vinyl chloride, where possible. Note, polyvinyl chloride (PVC) is allowable as it is a low-
volatile polymer of vinyl chloride and a component in widespread building materials that are
required for building construction, such as PVC piping and electrical components. Further, there
is still potential for construction materials to contain some amount of these compounds from
residual use of products which contain chlorinated solvents during the manufacture process of
various building materials (i.e., form release) that may not be documented on SDSs or in product
descriptions.

4.3 VIMS Effectiveness Results

The results and analysis of the sub-slab soil 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 soil 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.

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.
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.

Sub-Slab Gas and Indoor Air Sampling Reporting
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 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
one business day of receiving the validated laboratory data if TCE is detected at a concentration
exceeding 2.1 µg/m3 in indoor air based on the residential use of the building. However, during
21
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
the pre-occupancy sampling event no residents will be living in the building, so in the event of a
TCE concentration above this concentration without residents present, there would likely not be
a short-term exposure risk associated with residential use of the building. DEQ will also be
notified prior to report submittal if sub-slab and indoor air samples indicate a completed pathway
exists to discuss whether additional sampling or other measures are warranted. A report of the
sub-slab gas and indoor air sampling will be submitted to DEQ with the VIMS Installation
Completion Report.

22
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.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 with electric fans based on VIMS efficacy testing results, mitigation system
modifications and plans for additional VIMS efficacy testing 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 design engineer certifying the VIMP based on the results
of the influence testing discussed in Section 4.0.

Post-occupancy VIMS effectiveness monitoring will include proposed semi-annual sub-slab soil
gas sampling and indoor air sampling for two-years following initial occupancy of the Site
building. The post-occupancy sample locations will be selected based on the pre-occupancy
sampling data upon discussion and approval by DEQ. The sampling will be conducted using the
procedures described in this VIMP. If the post-occupancy sampling results indicate acceptable
risk levels, a request to modify or terminate sampling will 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 annual post-occupancy sampling event will take place
approximately six months after the start of occupancy of the building, or as otherwise approved
by DEQ.

23
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.doc
6.0 Future Tenants & Building Uses
The future use of the proposed Site building includes multi-family residential use. After
occupancy of the Site building, 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’s owners or management will be
instructed to contact appropriate parties to conduct the appropriate maintenance.

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. To aid in identification of the vapor mitigation piping, the construction contractor
will label the pipe (see Section 2.2) on accessible piping at intervals of no greater than 10-linear
feet.

As part of the annual Land Use Restriction Update submittal that is required under the filed
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/third & urban/t&u-004 530 sugar creek (kaiser fluids tech)/vimp/rev 1/20026-16-060 _vimp_530 e sugar creek_rev 1.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
system is 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 a statement provided by the design engineer 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 designee of
the design engineer, results of the influence testing, results of the analytical testing, and QA/QC
measures as described in this VIMP. Notable deviations from the approved design will be
provided in the report.

LUR 15.g. of the filed Brownfields Agreement generally states that building(s) on the Site 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 sampling event, a report
will be submitted to DEQ to document the sampling activities, results, and recommendations.

TECHNICAL DATA
REMEDIATION TECHNOLOGIES
EVOH technology provided in VI-20™ geomembrane
has been shown to have VOC di usion coe cients 20
times lower than an 80 mil HDPE geomembrane.
DESCRIPTION
VI-20™ is a 7-layer co-extruded EVOH geomembrane made using high quality virgin-grade polyethylene
and barrier resins that provide unmatched impact strength as well as superior resistance to VOC
vapor transmission. EVOH technology serves as a highly resilient underslab and vertical wall barrier
designed to restrict methane, radon and other harmful chemicals. Applications for EVOH originated
in the manufacturing of automotive fuel systems to control emissions of hydrocarbons, whose use
was mandated by the US EPA and the CA Air Resources Board (CARB) to reduce VOC emissions.
APPLICATION
VI-20™ is a 20-mil, high performance poly-ethylene-EVOH copolymer geomembrane, specially
designed for use as a VOC barrier when used in conjunction with Liquid Boot® spray-applied gas
vapor membrane to minimize gas vapor and nuisance water (non-hydrostatic conditions) migration
into buildings. VI-20™ is ideal for applications with chlorinated solvents, BTEX and other PAHs.
BENEFITS
Polyethylene layers provide excellent chemical resistance and physical properties
EVOH barrier technology provides superior protection against diffusion of chemicals
when compared to typical HDPE geomembranes

PACKAGING
VI-20™ Geomembrane is available in the
following packaging option:
10 ft. x 150 ft. Rolls
INSTALLATION
For use as a component of the Liquid Boot® Plus system, VI-20™ geomembrane is rolled out on prepared sub-grade, overlapping seams a minimum of
six inches (6”). The geomembrane is cut around penetrations so that it lays fl at on the sub-grade and tight at all inside corners. A thin (20 mil) tack coat of
Liquid Boot® (“A” side without catalyst) is sprayed within the seam overlap. Once the VI-20™ geomembrane is installed, penetrations are then treated with
VI-20™ Detailing Fabric prior to installation of the Liquid Boot® spray-applied gas vapor membrane and UltraShield™ G-1000 protection course.

TECHNICAL DATA
REMEDIATION TECHNOLOGIES
In addition to superior chemical resistance performance,
Liquid Boot® spray-application e ectively seals penetra-
tions, footings, grade beams and other irregular surfaces
that are considered critical vapor intrusion pathways.
DESCRIPTION
Liquid Boot® is a seamless, spray-applied, water-based membrane containing no VOCs, which
provides a barrier against vapor intrusion into structures. Liquid Boot® is installed under slab and
on below grade vertical walls as a gas vapor barrier to minimize vapor and nuisance water migration
into buildings. Liquid Boot® spray-application directly to penetrations, footings, grade beams, pile
caps and other irregular surfaces, provides for a fully-adhered gas vapor barrier system.
APPLICATIONS
Liquid Boot® is used as an underslab and below-grade vertical wall gas vapor barrier, used
to minimize vapor and nuisance water (non-hydrostatic conditions) migration into buildings.
Liquid Boot® is ideal for methane migration control. Liquid Boot® is also NSF® certifi ed for use
as a potable water liner in concrete water reservoirs and tanks greater than 300,000 gallons
to protect the concrete from water seepage.
BENEFITS
Spray-application provides excellent sealing of penetrations, eliminating the need for
mechanical fastening
Seamless, monolithic membrane eliminates seaming-related membrane failures
Unique formulation provides superior protection from methane gases and water vapor
Fully adhered system reduces risk of gas migration
Protection from methane gas, VOCs, chlorinated solvents and other contaminates
INSTALLATION
Protect all adjacent areas not to receive gas vapor barrier. Ambient temperature shall be

11. Toxicological Information
Local effects Contact with eyes may cause irritation.
Chronic effects Prolonged exposure may cause chronic effects. Repeated or prolonged skin contact may cause
skin irritation and/or dermatitis and sensitization of susceptible persons.
Carcinogenicity This material contains petroleum asphalt. IARC has determined that there is inadequate evidence
that undiluted, air-refined asphalt is carcinogenic to animals. There is only limited evidence that
undiluted, steam-refined and cracking-residue asphalt are carcinogenic to animals. Additionally,
IARC has concluded that there is inadequate evidence that asphalts alone are carcinogenic to
humans.
Condensed asphalt fumes, which are generated under laboratory conditions and are chemically
different from those found during typical asphalt operations, have been reported to cause
bacterial mutations. However, inhalation of asphalt fumes by laboratory animals, during controlled
studies, did not produce lung cancer. Additionally, human studies have not established a link
between lung cancer and asphalt fume exposure to date. This product may contain trace amounts
of polynuclear aromatic hydrocarbons (PAHs) as naturally occurring constituents of crude oils
from which asphalt is derived. Some PAHs have been shown to be carcinogenic after prolonged
or repeated skin contact in laboratory animals.

TESTING DATA
DESCRIPTION
UltraShield™ G-800 is a polypropylene, staple fi ber, non-woven geotextile. The fi bers are needled-
punched, forming a stable network that retains dimensional stability relative to each other. The
geotextile is resistant to ultraviolet degradation and biological and chemical environments found
in soils. Manufacturing Quality Control tests have been performed and are accredited by the
Geosynthetic Accreditation Institute’s Laboratory Accreditation Program (GAI-LAP).
APPLICATION
UltraShield™ G-800 is designed for use as a underslab adhesion protection course specially
designed and required for underslab Liquid Boot® applications where the membrane
must remain attached to the underslab of the building. This is to ensure the membrane
remains in place despite soil settlement, which is common when building on a landfi ll.
BENEFITS
UltraShield™ G-800 is installed directly over the fi nished Liquid Boot® gas vapor barrier,
providing superior protection from other trades.
PACKAGING
UltraShieldTM G-800 is available in the following packaging option:
15 ft. x 180 ft. Rolls
UltraShield™ G-800 is a needle-punched, non-
woven geotextile with superior tensile strength and
puncture resistance.
GEOVENT Venting System
Improved Efficiency for Reduced Installation Costs
Venting systems are typically installed in conjunction with a vapor barrier when volatile or
explosive gases are present. GEOVENT is a low-profile pressure relief, trenchless
collection and venting system designed to improve venting efficiency and reduce
installation costs. GEOVENT has several advantages over trenched installations and can
be used as an “active” or “passive” venting system depending on the specific project. Used
in conjunction with LIQUID BOOT® vapor barrier, GEOVENT can alleviate the
accumulation of gas vapors under the slab.

Advantages of GEOVENT
Installed directly on subgrade eliminating costly trenching and potential interference or
damage to existing underground utilities
Placed in closer proximity to the vapor barrier allowing for more effective venting of
any accumulated vapor
Greater opening area per lineal foot of pipe and integral filter fabric allowing for higher
ventilation efficiency
Installed at a higher elevation reducing susceptibility to inundation from perched
groundwater that may accumulate beneath the building foundation
Flow characteristics meet or exceed that of a typical trenched installation. the overall
capacity of the system is far in excess of typical gas flux rates

How it works
Design Considerations
GEOVENT is a 3-dimensional vent core that is wrapped in a non-woven, needlepunched
filter fabric and is used with GEOVENT end outlets, GEOVENT reducers, and pipework
components to form part of a passive and active sub-slab venting system.

GEOVENT can be installed directly onto the subgrade to eliminate trenching and potential
interference or damage to existing underground utilities.

Components Description
GEOVENT 1 ft x 165 ft roll
GEOVENT End Outlet GEOVENT - 100 mm pipe conversion
GEOVENT Reducer 100 mm pipe - 50 mm pipe conversion
Fabric Tape Hard cast fiber reinforced tape
Venting systems should be properly designed to adequately relieve pressure and reduce
gas concentrations from beneath the structure. CETCO can provide assistance with
GEOVENT layouts and design grids as well as detail drawings for these types of systems.

Geo-Seal® EV20 Product Specification Sheets & Installation Instructions

Geo-Seal® EV20
Product Data Sheet
EPRO Services, Inc. [phone] eproinc.com
Product Description
Basic Use: Geo-Seal EV20 is a standalone EVOH passive barrier
to mitigate vapor intrusion for sites deemed to be low risk. Users
can also use Geo-Seal EV20 in conjunction with an active sub-
slab depressurization (SSD) system to increase system efficiency
and add redundancy to the SSD system. Geo-Seal CORE is
applied within the Geo-Seal EV20 seam overlap, around pipe
penetrations, and at termination points to eliminate the need for
challenging tape. Combining a sheet membrane with detailing
spray helps increase installation efficiency while ensuring a
robust seal in critical areas.
Composition: Geo-Seal EV20 is a 20-mil composite EVOH
geomembrane. Geo-Seal EV20 also exceeds all Class A, B, and
C vapor barrier requirements.
Benefits
• 20 mil EVOH membranes have the same chemical diffusive
properties as 60 and 80 mil HDPE liners.
• Spray applied seams enhance seam integrity and increase
the rate of production. Taped seams’ integrity can be
compromised in cold or wet conditions.
• Geo-Seal EV20 is smoke tested to ensure proper installation.
• Meets class A, B, and C vapor barrier standards
Limitations
• Thinner mil vapor intrusion barriers are less durable than
thicker composite systems.
• Additional cushion geotextile may be required to protect
Geo-Seal EV20 from additional aggregate layers.
• Additional weight should be used during application in
windy conditions to secure the system in place.
• A more robust composite system should be utilized for sites
with elevated risk or more complex applications.

VAPORBLOCK® PLUS™ PLACEMENT
1.1. Level and tamp or roll granular base as specified. A base for a gas-reduction system may require a 4” to 6” gas permeable layer of clean coarse aggregate as specified by your architectural or structural drawings after installation of the recommended gas collection system. In this situation, a cushion layer consisting of a non-woven geotextile fabric placed directly under VaporBlock® Plus™ will help protect the barrier from damage due to possible sharp coarse aggregate.
1.2. Unroll VaporBlock® Plus™ running the longest dimension parallel with the direction of the pour and pull open all folds to full width. (Fig. 1)
1.3. Lap VaporBlock® Plus™ over the footings and seal with Raven Butyl Seal tape at the footing-wall connection. Prime concrete surfaces, when necessary, and assure they are dry and clean prior to applying Raven Butyl Seal Tape. Apply even and firm pressure with a rubber roller. Overlap joints a minimum of 6” and seal overlap with 4” VaporSeal™ Tape. When used as a gas barrier, overlap joints a minimum of 12” and seal in-between overlap with an optional 2-sided Raven Butyl Seal Tape. Then seal with 4” VaporSeal™ Tape centered on the overlap seam.

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)

1.5. Sealing side-by-side multiple penetrations (option 1);
A) Cut a patch large enough to overlap 12” in all directions (Fig. 7)
of penetrations.
B) Mark where to cut openings and cut four to eight slices about
3/8” less than the diameter of the penetration for each.
C) Force patch material over penetration to achieve a tight fit and
form a lip.
D) Once patch is positioned, seal the perimeter to the membrane
by applying 2-sided Raven Butyl Seal Tape in-between the two
layers. (Fig. 8)
E) After applying Raven Butyl Seal Tape between the patch and
membrane, tape around each of the penetrations and the patch
with VaporSeal™ 4” tape. (Fig. 9) For additional protection apply
POUR-N-SEAL™ or an acceptable polyurethane elastomeric
sealant around the penetrations. (Fig. 10)

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.

Option 2
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.
