Vapor Intrusion Mitigation Plan – Rev. 1 Clanton Road Property
505, 515, 521, & 525 Clanton Road Charlotte, North Carolina H&H Job No. KAI-003
1.0 Introduction

On behalf of Kairoi Properties, LLC (Prospective Developer or PD), Hart & Hickman, PC
(H&H) has prepared this Vapor Intrusion Mitigation Plan (VIMP) for the proposed residential
apartment development at the Clanton Road Brownfields property (Brownfields Project No.
25098-21-060). The Brownfields Property is located at 505, 515, 521, and 525 Clanton Road in
Charlotte, Mecklenburg County, North Carolina (Site). The Site consists of two contiguous
parcels (Mecklenburg County Parcel Nos. 14513304 and 14513305) that total approximately 6.8
acres of land located in the lower South End area of Charlotte. A Site location map is provided
as Figure 1, and the Site and surrounding area are shown in Figure 2.

Proposed redevelopment plans include construction of five townhome buildings in the western
portion of the Brownfields property, and construction of a five-story multi-family residential
apartment building with an associated parking deck and paved vehicle access roads in the eastern
portion of the Brownfields property. The eastern portion of the proposed redevelopment is
known as Clanton Road Apartments. Note this VIMP has been prepared for the eastern portion
of the Brownfields property that will be developed with the five-story multi-family apartment
building. VIMPs for future phases of development will be submitted to the North Carolina
Department of Environmental Quality (DEQ) under separate cover. An overlay of the Clanton
Road Property redevelopment plan is provided as Figure 3.

Brief summaries of the history and previous assessments completed at the Brownfields property
are provided in the following sections.

1.1 Site Background Information

The western and central portions of the Site were developed with two commercial buildings that
were constructed in the early 1970s and 1980s. The former western and central Site buildings
were most recently occupied by McLeod Addictive Disease Center. The eastern portion of the
Site was developed with a motel that was constructed in 1983. The Site buildings were
demolished in 2022 and 2023 during initial redevelopment activities. Remaining portions of the
Site consist of paved parking and vehicle access drives and vegetated areas. The Site and
surrounding area are shown in Figure 2.

1.2 Previous Assessment Activities

2021 Assessment Activities
In July and August 2021, Phase I Environmental Site Assessments (ESAs) were completed at the
Site by ECS Carolinas, LLP (ECS). Based on findings from the Phase I ESAs, groundwater and
soil gas sampling activities were completed by ECS in September 2021. The September 2021
assessment included installation and sample collection from four temporary monitoring wells
(TW-1 through TW-4) and three temporary exterior soil gas sampling points (SG-1 through SG-
3).

Laboratory results identified chloroform at a concentration above the DEQ Residential Vapor
Intrusion Groundwater Screening Level (GWSL) in one groundwater sample (TW-3) collected in
an upgradient location along the northern Site boundary. No other organic compounds were
detected at concentrations above the DEQ Residential GWSLs in the groundwater samples
collected in 2021.

Laboratory analytical results identified several VOCs at concentrations above the laboratory
reporting limits in the exterior soil gas samples. Vinyl chloride (6.1 micrograms per cubic meter
[µg/m3]) was detected at a concentration above the DEQ Residential Vapor Intrusion Soil Gas
Screening Level (SGSL) in one exterior soil gas sample located in the northern portion of the
Brownfields property. No other VOCs were detected at concentrations above the DEQ

Residential Vapor Intrusion SGSLs during the September 2021 assessment activities. Details of
the assessment are documented in the Environmental Assessment Services Report dated October
1, 2021, and copies of the data tables and sample location maps prepared for the September 2021
assessment activities are provided in Appendix A.

1.3 Brownfields Assessment Activities

To address environmental concerns associated with the Site, the PD entered the Site into the
DEQ Brownfields Redevelopment Section and received eligibility in a letter dated February 18,
2022. To further evaluate the potential for impact to the Site from on-Site and nearby off-Site
operations, Brownfields assessment activities were completed at the Site in November 2022 and
March 2023. Brownfields assessment activities included installation and sample collection from
five permanent monitoring wells, collection of 14 soil samples, installation and sample collection
from 34 temporary exterior soil gas monitoring points, and installation and sample collection
from 14 temporary sub-slab soil gas monitoring points. The sampling activities and results are
documented in a Brownfields Assessment Report & Receptor Survey Revision 3.0 dated
December 15, 2022 and revised May 25, 2023. Copies of the data summary tables and sample
location maps are included in Appendix A, and a brief summary of the sampling results is
provided below.

Soil Assessment Activities
During Brownfields assessment activities, a total of 14 soil samples were collected from ten
borings advanced in areas of potential concern or in areas of planned disturbance during future
Site development. No organic compounds were detected at concentrations above the DEQ
Residential or Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs) with the
exception of methylene chloride which was designated as a laboratory contaminant in the
laboratory analytical report. Mercury was not detected at concentrations above the DEQ PSRGs
at the Site.

Groundwater Assessment Activities
In November 2022, ECS collected groundwater samples from five permanent monitoring wells
(MW-1 through MW-5). Tetrachloroethene or PCE (up to 4.1 micrograms per liter [µg/L]) was
detected at concentrations exceeding the DEQ 15A North Carolina Administrative Code
(NCAC) Groundwater Quality 2L Standard (2L Standard) of 0.7 µg/L but below the DEQ
Residential Vapor Intrusion GWSL in MW-1 and its duplicate sample. Based on information
provided in the environmental documents prepared for the Site, the sample identification labels
for the groundwater samples were inadvertently mislabeled as temporary wells (i.e., TW-1, TW-
2, etc.) during sampling activities. The compound chloroform (up to 1.5 µg/L) was detected at
concentrations above the DEQ Residential Vapor Intrusion GWSLs, but below the 2L Standard
in samples TW-1, TW-2, and TW-5. No other VOCs including trichloroethene (TCE) were
detected at concentrations above the DEQ Residential GWSLs or 2L Standards. No semi-
volatile organic compounds (SVOCs) were detected at concentrations above the laboratory
method detection limits in the groundwater samples. No metals including mercury were detected
at concentrations above the 2L Standards or DEQ Residential Vapor Intrusion GWSLs in the
groundwater samples.

Exterior and Sub-Slab Soil Gas Sampling
In November 2022 ECS sampled 34 exterior soil gas points and 14 sub-slab soil gas points
installed within the footprint of proposed Site buildings. Soil gas samples SG-1 through SG-11,
and sub-slab soil gas samples SS-1 through SS-8 were collected within the footprint of the
proposed multi-family building. In March 2023, ECS collected additional samples with an “R”
designation that were collected from the same parent location as the November 2022 sampling
event.

Benzene (up to 107 µg/m3), chloroform (up to 954 µg/m3), ethylbenzene (up to 347 µg/m3),
naphthalene (up to 126 µg/m3), PCE (up to 6,600 µg/m3), and m&p-xylenes (up to 1,410 µg/m3)
were detected in soil gas samples above the DEQ Residential Vapor Intrusion SGSLs at the Site.
Trichloroethene (TCE) was detected in several soil gas samples at concentrations above the
laboratory method detection limits, but below the DEQ Vapor Intrusion SGSLs. For the soil gas
and sub-slab soil gas samples collected within the proposed multi-family apartment building

footprint, TCE was only detected in samples SG-4/SG-4-R (up to 10.1 µg/m3), SS-5/SS-5R (up
to 3.45 µg/m3), and SS-7 (13.4 µg/m3) collected from the northeastern and east-central portions
of the Site.

1.4 Vapor Intrusion Assessment Activities

The DEQ Vapor Intrusion Screening Levels (VISLs) are conservative and based upon a Target
Cancer Risk (TCR) of 1 x 10-6 for potential carcinogenic effects and a Target Hazard Quotient
(THQ) of 0.2 for potential non-carcinogenic effects. The DEQ and Environmental Protection
Agency (EPA) acceptable risk levels for potential carcinogenic risks is a cumulative lifetime
incremental cancer risk (LICR) of 1 x 10-4 or less and the acceptable risk level for non-
carcinogenic risks is a cumulative calculated hazard index (HI) of 1.0 or less.

H&H utilized the DEQ Risk Calculators (July 2023) assuming a residential land use scenario to
evaluate potential cumulative risks for the soil gas to indoor air vapor intrusion pathway. To
model the potential for structural vapor intrusion under a hypothetical “worst-case” scenario,
H&H conservatively calculated the cumulative risks using the highest concentration of any
compound detected in any sub-slab or exterior soil gas sample collected at the Site.

Risk calculator results for a residential scenario for the 2022 and 2023 Brownfields assessment
activities indicate a cumulative LICR of 3.2 x 10-4 and a HI of 7.8. Based on results of the 2021,
2022, and 2023 sampling events, the cumulative carcinogenic and non-carcinogenic risks exceed
unacceptable threshold levels. Based on review of the laboratory analytical data and risk
evaluation results, potential structural vapor intrusion for the proposed apartment building will
be managed through installation of passive vapor intrusion mitigation system (VIMS) during
construction of the proposed building. The PD plans to install a passive VIMS, with the ability
to become active with the installation of electric fans if needed, during construction of the
proposed building as described herein.

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 Clanton Road Apartments multi-family building are included
in Appendix B. The following VIMS design drawings will be used to guide construction of the
VIMS:
• Sheets VM-0 and VM-1 show the VIMS layout on the ground floor levels (Basement
Level and Level 1);
o Sheets VM-1-1, VM-1-2, VM-1-3, and VM-1-4 show detailed views of Level 1.
• Sheet VM-2 shows the VIMS layout on Levels 2 through 5;
• Sheet VM-3 shows the VIMS layout on the roof; and
• Sheets VM-A, VM-B, and VM-C include section details and specifications.

To reduce the potential for structural vapor intrusion, the VIMS on the Basement Level and
Level 1 will operate as a passive sub-slab venting system that includes a network of horizontal
sub-slab collection piping and vertical above-slab riser piping that will discharge collected
vapors above the roof of the building. The VIMS will also include the installation of a vapor
barrier below the ground floor slabs of the occupiable spaces. The VIMS for the building will be
divided into several VIMS mitigation areas that are generally separated by features including
slab-steps, the parking deck, interior corridors, or large footers.

The proposed five-story high-density apartment building will consist of approximately enclosed
occupiable ground floor space of 73,500 square feet (sq ft) which will be split into two levels
(Basement Level and Level 1). The building is proposed to have a slab-on-grade construction
with thickened slabs below load-bearing walls. A retaining wall will be constructed between the
Basement Level and Level 1 as depicted in the VIMS design drawings (Appendix B). The
ground floor spaces are proposed to include residential units, amenity areas, and a leasing office.

The building contains four elevators and four stairwells that extend from the ground floor
through the building. The Basement Level of the parking garage contains a maintenance room
and bike storage in the northern portion of the parking garage, and a trash room and elevator

lobby in the eastern portion of the garage. There are no proposed retail areas or pour-back areas
proposed for the apartment building.

Redevelopment plans include the construction of two open-air courtyards and an open-air
parking garage within the footprint of the building. The courtyards and the parking garage will
extend from the ground level through the top of the building. The enclosed upper levels of the
building will primarily consist of residential units. An outdoor pool and resident amenity area is
proposed for the northwestern portion of the building roof. The remaining portions of the roof
will be a flat roof with a parapet around the perimeter to house mechanical equipment and will
be inaccessible to residential occupants.

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 (e.g., washed/clean #57 stone or similar high permeability stone
approved by the Engineer certifying the VIMP) below the concrete slab of the building. A vapor
intrusion barrier (vapor barrier) will be installed above the base course stone layer and directly
beneath the slab. Please note that the horizontal collection piping network will be installed
within the base course stone layer prior to placement of the vapor barrier beneath enclosed and
occupiable spaces of the proposed building. The horizontal vapor collection piping is discussed
further in Section 2.2.

The vapor barrier will consist of Vaporblock® Plus 20 (VBP20) manufactured by Viaflex, Inc.
(Viaflex), formerly known as Raven Industries. As an alternative, Drago® Wrap Vapor Intrusion
Barrier (Drago Wrap) manufactured by Stego® Industries (Stego) may be used. The selected
vapor barrier will be installed per manufacturer installation instructions. An equivalent vapor
barrier may also be used pending review and approval by the VIMS design engineer and DEQ.
Copies of the vapor barrier manufacturer installation instructions are provided in Appendix C.

The vapor barrier will be installed over the sub-slab stone layer on the ground floors (Basement
Level and Level 1) in the areas shown on Sheets VM-0 and VM-1. Vapor barrier will also be
9
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/kairoi (kai)/kai.003 - clanton road/vims/report/rev 1/25098 - vimp_clanton road_rev 1.doc
installed along applicable vertical retaining walls adjacent to living spaces, and vapor barrier will
be installed below and on the sides of the elevator pits.

Each vapor barrier manufacturer recommends specific sealing agents (mastics, tapes, etc.) for
their product. Therefore, and in accordance with the manufacturer installation instructions, the
use of alternative vapor barrier products not approved by the manufacturers for sealing shall not
be used. The exterior edges of the vapor barrier will be attached and sealed to building footings,
or placed below the footers, and subsurface concrete features utilizing the tape and sealants
specified in the manufacturer instructions. Seams within the building footprint will have a
minimum of 12 inches of overlap and will be sealed with the tape specified in the manufacturer
instructions.

In areas where the vapor barrier is sealed directly to concrete or concrete masonry units (CMU),
double-sided tapes (e.g. Viaflex Butyl-Seal or Drago-Tack Tape) or other sealants approved by
the manufacturer must be used. 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 12 inches of patch
extends beyond the damaged area. The seams of the patch will then be sealed using the
manufacturer recommended tapes or other sealants.

In areas where multiple utility penetrations are present, such as utility banks, and the use of the
tape recommended by the manufacturer is not practical or deemed as “ineffective” by the
Engineer certifying the VIMP, an alternative sealant product specified by the vapor barrier
manufacturer will be used, such as Viaflex Pour-N-Seal™ or Drago® Sealant, or manufacturer
approved mastics. 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 below the ground floor occupiable spaces will be accomplished using
horizontal slotted or perforated collection piping installed in the gravel layer which will collect
vapor from beneath the ground floor slabs and discharge the vapors at the roof through vertical
riser piping. Sub-slab piping will consist of 3-inch diameter Schedule 40 (SCH 40) PVC piping
and above-slab piping will consist of either 3-inch diameter SCH 40 PVC piping and fittings
unless otherwise specified in the design drawings (Appendix 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 Appendix C.

Sub-slab venting below the ground floor occupiable spaces will be accomplished using
horizontal slotted or perforated collection piping installed in the gravel layer which will collect
vapor from beneath the ground floor slabs and discharge the vapors at the roof through vertical
riser piping. Sub-slab piping will consist of 3-inch diameter Schedule 40 (SCH 40) PVC piping
and fittings, unless otherwise specified in the VIMP. Above-slab piping will consist of 3-inch
SCH 40 PVC piping and fittings. Note that solid sections of VIMS piping, both below and
above grade, shall maintain a minimum 1% slope toward slotted sections or open ends to drain
potential condensation water.

As an alternative to 3-inch diameter SCH 40 PVC horizontal piping, soil gas collector mat
manufactured by Radon Professional Discount Supply (Radon PDS) may be used for sub-slab
vapor collection piping. The Radon PDS soil gas collector mat is a polystyrene, plastic,
rectangular conduit with a geotextile fabric covering. The mat is 1 inch thick and 12 inches wide
and is specifically designed for collecting soil gas from below a building. If used, the soil gas
collector mat will be connected to the proposed 3-inch diameter vertical risers and footing
crossings using Radon PDS-manufactured riser connection fittings. In lieu of the soil gas
collector mat extending unprotected through concrete, solid PVC pipe must be used as a soil gas
collector mat conduit in locations of footings and thickened slab crossings. Product
specifications for the soil gas collector mat are provided in Appendix 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 an alternative ventilator approved in
advance by the 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 evacuation
of potential vapors below the slab and 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
the 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 codes.

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 must be inspected by the Engineer certifying the VIMP or its designee
before covering risers.

An electrical junction box or outlet (120 VAC, 15 amp minimum) will be installed on the roof of
the building in locations that can be reached from exhaust discharge locations. The electrical
junction box or outlet will only be used should the connection of an electrical 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
12
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/kairoi (kai)/kai.003 - clanton road/vims/report/rev 1/25098 - vimp_clanton road_rev 1.doc
measurements and for the collection of sub-slab soil gas samples for laboratory analysis. The
monitoring point locations are shown on Sheets VM-0 and VM-1 (Appendix B).

In general, monitoring points are placed at remotely distant locations from vertical riser piping
locations and in representative areas of the ground floor occupiable areas. Product specifications
for the proposed floor cleanout and wall-mounted monitoring points are provided in Appendix C.
To reduce VOCs from construction materials in future sub-slab soil gas samples submitted for
laboratory analysis, the monitoring point components will be connected using threaded
connections or approved low VOC-containing products (see Section 2.4).

To provide more vacuum influence locations during construction, in addition to the permanent
monitoring points, three temporary monitoring points (TMP-1, TMP-2, and TMP-3) will be
installed on Level 1 of the building for use during influence testing. The temporary monitoring
points will be abandoned following successful influence testing and/or sampling as discussed in
Section 4.0. The temporary points will be abandoned by removing the pipe to the extent
possible, filling in the hole with an air-tight sealant (such as Viaflex Pour-N-Seal or Viaflex-
approved Con-Dri Mastic), 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 will be constructed,
pending approval by the Engineer certifying the VIMP. The replacement point(s) shall consist of
one of the specified designs in the design drawings or a Cox Colvin Vapor Pin® installation if
necessary. DEQ will be notified in advance if monitoring points are relocated significantly in
relation to 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 piping, vapor barrier, and monitoring points shall be protected by the installation
contractor and subcontractors throughout the project. Protective measures (e.g., flagging,
protective boards, etc.) shall be used as needed to prevent damage to the monitoring points. The
monitoring points and riser duct piping must be capped with a removable slip-cap or expandable
plugs immediately following installation to prevent water and/or debris from entering the VIMS.

For each phase of construction (above and below slab), construction contractors and
subcontractors shall use “low or no VOC” products, when possible. Furthermore, the
construction contractors shall not use products containing the compounds PCE or TCE. Before
the submittal of a VIMS Installation Completion Report, the construction contractor and
subcontractors shall be directed to provide safety data sheets (SDSs) for products and materials
used during construction. SDSs provided by the contractor and subcontractors, including but not
limited to building products, will be included in the VIMS Installation Completion Report.

Utility Trench Dams
Sub-grade utilities proposed for the multi-family apartment building include sanitary sewer,
potable water, and electrical utilities. All of the sub-grade utilities are proposed to extend from
Blairhill Road located on the southern side of the property. There are no sub-grade utilities
proposed to be installed along the northern or northeastern portion of the property where the
TCE concentrations were detected during prior assessment activities (see Section 1.0). The
assessment samples collected on the southern side of the property did not indicate the presence
of PCE or TCE in groundwater, soil gas, or sub-slab soil gas samples, and the samples in this
area generally only contained low-level concentrations of other VOC compounds. Therefore, the
installation of utility trench dams that sometimes can be used to prevent vapor migration along
utility trenches is not warranted for the multi-family apartment building. Note, if utility conduit
plans change and sub-grade utility mains are installed in the northeastern portion of the property,
then utility trench dams may be warranted upon review by the VIMS design engineer.

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.

Each component of the VIMS shall be inspected and approved by the Engineer certifying the
VIMP, or the Engineer’s designee, prior to being covered. Notable deviations from the VIMS
design shall be communicated to DEQ with DEQ approval and PE seal/certification potentially
warranted for the deviation(s).

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.
Locations where multiple penetrations are present and where products such as Viaflex Pour-N-
Seal™ are used will be photographed and noted on the field logs. In addition, areas along
exterior footings where vapor barrier does not extend to the ground surface due to building
conflicts will be documented on the field logs.

The contractor shall notify the Engineer certifying the VIMP, or his/her designee, with a two-
business day notice prior to a planned inspection, and H&H will provide a subsequent two-
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 sub-slab vacuum communication across the slab and to demonstrate that
sufficient sub-slab depressurization can be obtained should electric fans be needed in the future.
Influence testing will be conducted following installation of the horizontal collection piping,
placement of the vapor barrier, and 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 vacuum measurements will be collected at each
monitoring point within the treatment area. 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 locations in each VIMS treatment area is considered sufficient to provide
sub-slab depressurization. Vacuum influence testing results will be submitted to DEQ as part of
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 the VIMS Installation Completion Report.

4.2 Pre-Occupancy Sub-Slab Soil Gas Sampling

Following VIMS installation, but prior to occupancy of the building, three sub-slab soil gas
samples will be collected from select monitoring points on the Basement Level and eight sub-
slab soil gas samples will be collected from the slab-on-grade area of Level 1 (11 samples total)
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. The sub-slab soil gas samples are proposed to be collected from the multi-family
16
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/kairoi (kai)/kai.003 - clanton road/vims/report/rev 1/25098 - vimp_clanton road_rev 1.doc
apartment building at the following monitoring point locations listed below and depicted on
Figure 4A and Figure 4B:

• Basement Level: MP-B-2, MP-B-4, and MP-B-5
• Level 1: MP-1, MP-4, MP-6, MP-8, MP-10, MP-13, MP-15, and MP-18

One duplicate sub-slab soil gas sample using a laboratory-supplied “T” fitting for laboratory
QA/QC purposes will be collected during each 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 the 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 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.

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
17
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/kairoi (kai)/kai.003 - clanton road/vims/report/rev 1/25098 - vimp_clanton road_rev 1.doc
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 DEQ
Residential Vapor Intrusion SGSLs to the extent possible.

4.3 Indoor Air Sampling

As summarized in Section 2.0, the VOC compounds PCE and TCE were detected in groundwater
and soil gas samples collected in the northeastern portion of the property. As a precaution, in
addition to the sub-slab sampling, indoor air sampling will also be conducted within the
northeastern portion of the multi-family apartment building. The building is intended to be
occupied shortly following completion and initialization of the HVAC system. Therefore, the
indoor air sampling event will be conducted following complete installation of the VIMS and
after the building and/or sample area has been fully enclosed. When possible, the indoor air
sampling will be completed a minimum of two weeks after the installation of the ventilators but
may be conducted prior to initialization of the HVAC system(s).

Five indoor air samples are proposed to be collected from the ground floor level (Level 1) in the
northeastern portion of the building closest to the locations of historical detections of TCE at the
following locations:
• Indoor air sample IAS-1 will be co-located with the sub-slab soil gas sample collected
from monitoring point MP-8;
• Indoor air sample IAS-2 will be co-located with the sub-slab soil gas sample collected
from monitoring point MP-10;
• Indoor air sample IAS-3 will be co-located with the sub-slab soil gas sample collected
from monitoring point MP-1;
• Indoor air sample IAS-4 will be co-located with the sub-slab soil gas sample collected
from monitoring point MP-13;
• Indoor air sample IAS-5 will be co-located with the sub-slab soil gas sample collected
from monitoring point MP-B-2;

18
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/kairoi (kai)/kai.003 - clanton road/vims/report/rev 1/25098 - vimp_clanton road_rev 1.doc
The indoor 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 as a conservative measure. The
canisters will be set up so that the sample intake point is positioned approximately 5 ft above
grade (typical breathing zone height). In addition, during each indoor air sampling event, one
background ambient air sample will be collected from a location upwind of the building as
determined by conditions on the day of the sampling event. The indoor air sampling event is
proposed to occur concurrently with the sub-slab soil gas sampling (Section 4.2) and therefore
the duplicate sub-slab soil gas sample will be collected during the sampling event. If no sub-slab
soil gas samples are collected during an indoor air sampling event, then an indoor air duplicate
sample will be collected so there is one duplicate air sample per sampling event. 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 a representative sample 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 compounds detected in sub-slab soil gas samples and previously
identified Site contaminants of concern (COCs) and the select list will be confirmed with DEQ
prior to analyzing the indoor air samples. The analytical laboratory will be instructed to report
vacuum measurements at receipt and J-flag concentrations for each sample. The laboratory will
be requested to report compound concentrations to the lower of the laboratory method detection
limits or the DEQ Residential Vapor Intrusion IASLs to the extent possible. In addition, an
Indoor Air Building Survey form (Appendix C of the DWM VI Guidance) will be completed for
each sampling event.

19
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/kairoi (kai)/kai.003 - clanton road/vims/report/rev 1/25098 - vimp_clanton road_rev 1.doc
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 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.

4.4 VIMS Effectiveness Results

The results and analysis of the sub-slab soil gas and indoor air sampling will be submitted to
DEQ with the final VIMS Installation Completion Report (discussed in Section 7.0). After
receipt of the sub-slab soil gas analytical results, H&H will use the most recent version of the
DEQ Risk Calculator to evaluate cumulative potential vapor intrusion risks under a residential
scenario. H&H will consider the VIMS effective if the calculated sub-slab soil gas and indoor
air sample cumulative LICR is 1 x 10-4 or less for potential carcinogenic risks and the calculated
cumulative HI is 1.0 or less for potential noncarcinogenic risks.

If calculated cumulative risks for a residential scenario exceed acceptable levels for potential
carcinogenic and/or noncarcinogenic risks as a result of structural vapor intrusion, confirmation
sub-slab soil gas and/or indoor air samples will be collected from the area of potential concern.
If an additional round of samples indicates results within acceptable risk levels, no further pre-
occupancy sampling will be conducted. If calculated cumulative risks continue to exceed
acceptable levels for potential carcinogenic risks (greater than 1x10-4) and/or potential
noncarcinogenic risks (an HI above 1.0) as a result of structural vapor intrusion, considerations
will be made to convert the system from a passive system to an active system. The PD
acknowledges that no portions of the proposed building will be occupied without written
approval from DEQ following the completion of pre-occupancy sampling activities.

20
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/kairoi (kai)/kai.003 - clanton road/vims/report/rev 1/25098 - vimp_clanton road_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 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 Engineer certifying the VIMP 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 soil gas and indoor air samples
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 included in the VIMS
installation report based on the results of pre-occupancy sampling 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.

6.0 Future Tenants & Building Uses
The future use of the proposed Site building includes multi-family residential apartments. After
occupancy of the Site building, the building owner or property management group will maintain
or contract for maintenance of the vapor mitigation system. If vapor mitigation components are
damaged or need to be altered for building renovations, the building management will be
instructed to contact the maintenance department. The maintenance department shall contact a
NC PE to oversee or inspect the activities, and a report shall be submitted to DEQ detailing the
repairs or alterations. To aid in identification of the vapor mitigation 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.

Future VIMS maintenance and upkeep will be the responsibility of the building owner, or as
contracted under a property management group. As part of the standard annual Land Use
Restriction Update submittal that will be required as part of the pending Notice of Brownfields
Property, H&H recommends the building owner or property management group complete or
contract for 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. After construction of the
building is complete, H&H can prepare a VIMS operation and maintenance (O&M) plan for use
by the building owner that includes information about the installed VIMS and recommendations
for building inspections.

7.0 Reporting
A VIMS Installation Completion Report (sealed by a NC PE) documenting installation activities
associated with the development will be sub mitted to DEQ following confirmation that the
mitigation system is installed and effectively minimizing potential vapor intrusion risks to
building occupants. The report(s) 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, when relevant, VIMS effectiveness testing results, and relevant inspection
documents. The report will also include a statement from the engineer of record as to whether
the VIMS was installed following the DEQ-approved VIMP and is fully protective of public
health as defined in Section 1.0, and as evidenced by the VIMS inspections performed by the
engineer or its designee, results of the influence testing, results of the analytical testing, and
QA/QC measures as described in this VIMP. Deviations, if any, from the approved design will
be provided in the report and notable deviations from the approved design during or before
construction will be communicated to DEQ for potential DEQ review and approval.
The pending Notice of Brownfields Property agreement for the Site is expected to contain land
use restrictions that indicate the building shall not be occupied until DEQ provides written
approval for the installation and performance of the VIMS as documented in the installation
report. However, DEQ may, under certain circumstances, provide conditional compliance
approval with the submittal of a data summary with PE seal instead of the full VIMS
Installation Completion Report based on the timing of the proposed building occupancy date
and report review times.
After each semi-annual post-occupancy sampling event, a report will be submitted to DEQ to
document the sampling activities, results, and recommendations.

HIGH-STRENGTH EPOXY BONDING ADHESIVE
POUR-N-SEAL™
PRODUCT NAMEPOUR-N-SEAL™ (P/N: PNS1G)
MANUFACTURERViaflex, Inc.
821 W. Algonquin Street
Sioux Falls, SD 57104
PRODUCT DESCRIPTION
POUR-N-SEAL™ is a gray two-part medium viscosity high strength epoxy used to seal around multiple pipe penetrations in tight areas where pipe boots are not practical,
when installing VaporBlock® moisture and
gas barriers.
TECHNICAL DATA
Applicable Standards:• ASTM (American Society for Testingand Materials)• ASTM C881 Standard Specification for
Epoxy-Resin-Base Bonding Systems for
Concrete• ASTM D695 Standard Test Method forCompressive Properties of Rigid Plastics• ASTM D638 Standard Test Method for
Tensile Properties of Plastics
• ASTM C882 Standard Test method forBond Strength of Epoxy-Resin SystemsUsed with Concrete by Slant Shear• ASTM Standard Test Method for
Deflection Temperature of Plastics Under
Flexural Load in the Edgewise Position• ASTM D570 Standard Test Method forWater Absorption of Plastics
MATERIAL PREPARATIONStore material overnight to precondition at a temperature between 70° F to 80° F prior to use.
INSTALLATION
1. POUR-N-SEAL™ is used to seal
moisture and gas barriers to multiple pipepenetrations in situations where pipe bootsare not able to be installed due to the tightconcentration of the pipe penetrations.
2. Install the vapor/gas barrier as close as
possible to the penetrations by making asmall opening. Effort should be given tominimize large gaps in the barrier next tothe penetrations, this will also reduce the
amount of POUR-N-SEAL™ necessary to
complete an acceptable seal.3. To help concentrate the sealant aroundthe pipe penetration, a dam can be formedaround the pipe grouping with an adhesive
backed weather stripping foam. One gallon
covers 80 sq. ft. at a thickness of 20 mils.
4.Only mix the amount of material that can be used within the pot life of the epoxy,
approximately 36 minutes at 73° F. Premix
each component prior to combining. Pour “A” and “B” components together and thoroughly mix using a low speed drill with a mixing paddle. Scrape the sides and bottom
to assure a consistent blend.5.Once mixed, pour contents around the pipe penetrations, if needed a brush or flat wooden stick can be used to direct the sealant completely around all penetrations
and overlap the moisture/gas barrier to form
a continuous seal. Avoid Contact with skin (see SDS for complete safety precautions). Immediately dispose of any remaining mixed POUR-N-SEAL™ epoxy left in the container
to avoid excessive heat buildup.6.Depending upon the temperature. POUR-N-SEAL should be tack free in approximately 5 hours.
STORAGE/SHELF LIFEStore in dry environment between 40º F and 80º F (4º C-27º C). Do not allow product
to freeze. Shelf Life: 12 months from date
of manufacture in unopened containers properly stored. Protect from moisture.
AVAILABILITYPlease call your local construction supply distributor for availability of POUR-N-SEAL™
or call our toll free number at 800-635-3456.
SAFETY
POUR-N-SEAL™ “B” component contains amines and may cause severe burns upon skin contact for any length of time. Use OSHA-approved personal protective
equipment (PPE), including safety glasses,
gloves and confined space equipment/

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 DragoSeal™ Tape. (Fig. 1).
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
DragoSeal 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.

THE WORLD’S CHOICE FOR SOIL GASES FOR THREE DECADES!2
SOIL GAS COLLECTOR MAT FOR
RADON READY NEW CONSTRUCTION
According to the US EPA’s model standards for radon control systems in new building construction, a means for collecting soil gas should be installed beneath the slab.
More and more mitigators and buildiers are using PDS’ soil gas collector mat (SGC Mat) because its installation does not entail any special coordination with plumbers or other site contractors. Low profile mat saves time as it removes the need for trenching. Just lay radon mat down around the inside perime-ter of the foundation, secure it with spikes or land-scaping staples, and pour the concrete.
SGC mat is superior to other mat systems because of its thickness and it has a geotextile fabric cloth surrounding the entire mat material. This feature eliminates the need to lay a plastic 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 quali-ty of the concrete slab. When SGC mat is installed below the slab, you’re providing an airspace that in-tercepts radon--and other soil gases and vapors--be-fore it seeps into the building through the slab. SGC mat also works well as a soil gas collector beneath crawlspace barrier due to its low-profile.
WHY AND HOW IT WORKSThe 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 collection point. This creates incredible pressure field extension for post construc-tion system activation. The mat can support con-crete without compressing, yet is extremely light-weight 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 under-lying gravel and soil. The natural airflow through the mat then channels the radon to the T riser to pipe connection. From there, hazardous gas can be vent-ed safely through the roof of the building.
Another key element of a soil gas collection system is attaching the 4” riser* ( 3” and 6” options avail-able) 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 con-nections or fittings. Use SGC Seam Tape to ensure air tight splices and corners.

Begin work on the sub grade (soil, sand, or gravel) after the final preparation and before the concrete is poured. Start with T-Riser(s) and work out to en-sure smooth mat placement. Position the T-Riser(s) in appropriate location(s) and secure with nails or staples.
Slide mat into flat openings on either end of T-ris-er with a portion of the fabric around the outside. Tape the fabric to the outside of the T-Riser with duct tape and staple mat to the ground with land-scape staples to ensure soil contact remains during pour stage.
Mat is typically laid out in a rectangular loop in the largest area with branches or legs into smaller areas (FREE takesoffs at www.radonmat.com). There is no need to trench the mat. Roll out the SGC mat and 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 addition to corners, tee junctions & ends.
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.
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 matrix of the branch (or overlap 1/2”)to the matrix of the main loop. Pull the filter 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.

INSTALLATION INSTRUCTIONS
All openings in the fabric at joints, T’s, and ends of branches should be taped to keep out concrete.
Stub up a few feet of 4” schedule 40 PVC** from all T risers before pour. Seal with caulk and screws. This ensures no concrete aggregate enters the ris-er during slab pour. Be sure to label “CAUTION RADON REDUCTION SYSTEM” on all pipe. **(6” PVC may be substituted--for large multifamily proj-ects. Simply cut T riser 4” insert away to reveal 6” Legacy T Riser). PVC sizes vary by code and design. 3”, 4”, & 6” schedule 40 PVC are acceptable.
When the building is ready for the vent pipe to be installed above the slab, fit to pre-stubbed PVC with PVC straight connect. Always label “CAUTION RADON REDUCTION SYSTEM” every 10 feet to avoid confusion on site and for the building occupants.

STEP SEVEN
STEP EIGHT
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 al-ways enter the T riser from at least two directions and exhaust to pipe vertically.

*These are the manufacturer’s instructions to ensure a proper functioning system. Certain code variants across the US have more lax or more con-
servative requirements. PDS’ soil gas collector can be installed to meet any code requirement (as of publication of this document). Please reach out
to PDS or a certified radon mitigator for consulting on specific code variants.

MAKING CORNERS
AND SPLICES
The geotextile 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 to-gether. 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 using PDS SGC seam tape. 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 allows for ei-ther 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 enter-ing. Cap the riser to ensure no concrete enters. T Riser caps can be purchased 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. Secure mat to the ground with staples so riser doesnot float.

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 taped closed at seams of splices and corner to sufficiently keep the uncured concrete from entering.
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 to withstand concrete workers and their wheel barrows.

It also is a chemically inert, highly stable, expandable graphite strip, tested and proven in positive pressure conditions to withstand both hot smoke and hot gasses, resulting in the longer integrity of a door assembly. More economical to use than specially modified doors in “tested assembly only” classifications. Chemically inert, and therefore will not degrade from carbon dioxide and ozone like the many intumescents being offered by other manufacturers.
Hot Smoke Seal™ is not affected by moisture and will not break down like fiber or cellulose based products and does not require periodic after market field inspections.
Insulation: is a rigid mineral wool (stone wool) insulation board for high temperature industrial applications subject to light mechanical loads.] - 2” thickness.
