VIMS Installation Completion Report Old Pineville Road
Old Pineville Road Townhomes – Buildings 1010, 1011, & 1012 Charlotte, North Carolina Brownfields Project No. 10061-06-060 H&H Job No. NVR-010
1.0 Introduction

Hart & Hickman, PC (H&H) has prepared this report to document vapor intrusion mitigation
system (VIMS) installation, influence testing, and post-construction sub-slab soil gas assessment
activities completed at the Old Pineville Road Brownfields property (Brownfields Project No.
10061-06-060) located at 4928 Old Pineville Road and 649 Scholtz Road in Charlotte,
Mecklenburg County, North Carolina (Site or subject Site). The redevelopment is known as Old
Pineville Townhomes, and is being developed with for-sale residential townhomes by Ryan
Homes, an NVR, Inc. (NVR) company. The Site development plan includes construction of fifteen
(15) townhome complexes which includes one 3-unit townhome complex, one 4-unit townhome
complex, five 7-unit townhome complexes, and eight 8-unit townhome complexes for a total of
106 individual residential townhome units. This report has been prepared for Old Pineville Road
Townhomes Building 1010 with eight units (Units A through H), Building 1011 with eight units
(Units A through H), and Building 1012 with seven units (Units A through G). Buildings 1010
and 1011 are located in the southern central portion of the Site and Building 1012 is located in the
northwest corner of the Site. A Site location map is provided as Figure 1, and a Site Map depicting
the building numbers is provided as Figure 2.

Assessment activities were completed at the Site in January 2007 to evaluate subsurface conditions
for potential impacts associated with historical on-Site and nearby off-Site operations. Results of
groundwater assessment activities indicated that there are not compounds present at concentrations
that pose significant risks for structural vapor intrusion at the Site based on a residential use
scenario. For ease of reference, the January 2007 data summary tables and a sample location map
are included in Appendix A.

A Brownfields Agreement between the North Carolina Department of Environmental Quality
(DEQ) and John J. Huson was recorded for the Site on January 8, 2008. Land Use Restriction
No. 4 in the recorded Brownfields Agreement generally states that no residential construction or
conversion of any structure to residential use may occur at the Brownfields property without
written notification to DEQ and a VIMS has been installed to the satisfaction of a professional
engineer licensed in North Carolina.

In accordance with the DEQ Brownfields Program Minimum Requirements for Townhome
Developments document, and to be in general compliance with the Brownfields Agreement, the
prospective developer (PD) elected to install a passive VIMS during construction of each proposed
townhome building. H&H prepared a Vapor Intrusion Mitigation Plan (VIMP) and revisions to
the VIMP based on DEQ comments. The final VIMP dated January 18, 2021, was approved by
DEQ in a letter dated February 15, 2021.

The DEQ-approved VIMP includes installation of a passive VIMS in each of the townhome
buildings and post-installation sub-slab soil gas sampling. This report documents installation of
the VIMS for Buildings 1010, 1011, and 1012. Following installation of the VIMS in other Site
townhome buildings and completion of post-construction sampling, additional installation
completion reports will be submitted under separate cover.

A discussion of VIMS installation activities is provided in Section 2.0, a summary of sub-slab soil
gas assessment activities is provided in Section 3.0, and summary and conclusions based on the
results of the VIMS installation and soil gas assessment activities are provided in Section 4.0.

2.0 VIMS Installation and Influence Testing

Buildings 1010 and 1011 consist of eight individually owned three-story townhomes, and Building
1012 consists of seven individually owned three-story townhomes. Buildings 1011 and 1012 are
built with thickened concrete footers and block walls with a concrete slab on-grade foundation.
Building 1012 was constructed with a monolithic concrete slab on-grade foundation and concrete
footings below load bearing walls. The block walls were constructed prior to the slab-on-grade
concrete pour and the thickened footers in Building 1012 were poured at the same time as the slab
on grade. Each individual unit includes a stairwell, garage, and living spaces located on the ground
floor of the structure, and the ground floor footprint for each townhome unit totals approximately
640 square feet.

2.1 VIMS Installation

The DEQ-approved VIMP included installation of Vaporblock® Plus 20 (VBP20) vapor barrier
manufactured by Raven Industries (Raven) beneath the concrete slab of the townhouse buildings.
VBP20 is an ASTM-certified 20-mil, multi-layer, chemically resistant vapor barrier, designed to
prevent the migration of volatile organic compounds. Technical specifications and installation
instructions obtained from Raven for the VBP20 vapor barrier are provided in Appendix B.

The vapor barrier was installed per manufacturer installation instructions (Appendix B). Briefly,
VBP20 was installed by the construction contractor to cover the ground surface below the entire
area of the buildings’ ground floor slabs. The exterior edges of the VBP20 were sealed to the
concrete foundations utilizing Butyl Seal double-sided tape. Seams within the building footprint
have a minimum 12-inch overlap and were sealed with VaporSeal™ tape. Small puncture holes
were sealed with VaporSeal™ tape, and larger holes around utility penetrations were repaired
using a patch that overlaps the penetration and then were taped along the seams.

The VIMP also included installation of a passive mitigation system beneath the ground-level slab
of each building to reduce the potential for vapor intrusion into the townhome units by vapor

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/nvr, inc/nvr-010 opr/bldg completion reports/buildings 10, 11, 12/report/10061_vims install_buildings 1010, 1011, & 1012_opr.docx
extraction. Because these units contain ground floor garages adjacent to living spaces, the VIMS
and sub-slab vapor extraction treatment was extended below the ground-level garages of the
townhomes. For Buildings 1010 and 1011, sub-slab vapor extraction is accomplished using (PVC)
vapor collection/conveyance piping which collects vapor from beneath the ground floor slabs of
each building and discharges the vapor through exhaust stacks above the building roof. In Building
1012, soil gas collector mat manufactured by Radon Professional Discount Supply (Radon PDS)
was used as an alternative sub-slab vapor collector pipe to the proposed sub-slab slotted PVC
piping below the townhome units.

The soil gas collector mat is a polystyrene plastic rectangular conduit with a geotextile fabric
covering that is 1-inch thick and 12-inches wide specifically designed for collecting soil gas from
below a building. The soil gas collector mat was connected to the vertical risers using Radon PDS
manufactured riser connector fittings in accordance with the manufacturer installation instructions.
Please note that DEQ did not approve this VIMP modification, however the modification was
approved by the design engineer (a NC Professional Engineer) because the soil gas collector mat
and accessories are an equivalent sub-slab soil gas collector conduit to the PVC piping proposed
in the VIMP. In addition, the Radon PDS mat is an acceptable soil gas collector as indicated in
the ANSI/AARST 2020 Reducing Radon in New Construction of 1 & 2 Family Dwellings and
Townhouses document.

The passive VIMS is also enhanced with an Empire turbine ventilator TV04SS (stainless steel)
wind driven turbine that is designed to promote air exhaust from the conveyance piping. The
Empire turbine ventilator was approved by the design engineer and is a ventilator similar to the
Empire Syphon specified in the VIMP. Each townhome unit contains individual sub-slab
collection systems, riser conveyance piping, and a wind-driven ventilator. Product specification
sheets for the turbine ventilator fan, slotted piping, and soil gas collector mat are included in
Appendix B.

To further enhance sub-slab vapor transmission and collection effectiveness, a uniform layer of
high permeability stone (clean #57) was installed directly below the concrete slab to allow for air
5
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/nvr, inc/nvr-010 opr/bldg completion reports/buildings 10, 11, 12/report/10061_vims install_buildings 1010, 1011, & 1012_opr.docx
movement beneath the entirety of the slab. Sub-slab vapor collection piping (3-inch diameter) or
soil gas collector was installed within the high permeability stone layer. The thickness of the high
permeability stone around the piping extends a minimum of 1-inch below the sub-slab piping or
soil gas collector mat and was installed at a minimum thickness of 4 inches across the slab.

In the event the system needs to be activated with electric fans, one vacuum monitoring point was
installed in each townhome unit to measure the pressure differential between indoor air and the
sub-slab and for collection of sub-slab soil gas samples. The locations of the monitoring points
are depicted in the as-built drawings provided in Appendix C.

During installation of the VIMS in Buildings 1010, 1011 and 1012, H&H conducted inspections
during various phases of construction to confirm the VIMS was installed in accordance with the
VIMP. Inspections were completed during the following phases:
• after installation of sub-slab horizontal collection system within the gravel base;
• following placement and sealing of the vapor barrier and prior to pouring the concrete
building slab; and
• after installation of vertical exhaust riser pipe and wind-driven ventilator installations.

Based upon inspections completed during the VIMS installation activities, the VIMS was installed
in general accordance with the DEQ-approved VIMP with the exception of the soil gas collector
mat modification discussed above. VIMS details and specifications, and a VIMS as-built drawing
which depicts the VIMS layout are included in Appendix C. A representative photographic log of
the VIMS installation activities is provided in Appendix D.
2.2 VIMS Influence Testing
H&H completed influence testing for Buildings 1010, 1011, and 1012 on October 13, 2021,
November 4, 2021, and December 15, 2021, respectively. The influence testing was completed to
evaluate system sub-slab communication and to confirm that adequate vacuum can be obtained
should an active depressurization system be needed in the future. DEQ considers 4 Pascals (Pa),
6
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/nvr, inc/nvr-010 opr/bldg completion reports/buildings 10, 11, 12/report/10061_vims install_buildings 1010, 1011, & 1012_opr.docx
or 0.016-inches of water column (in-WC), differential pressure the minimum vacuum needed for
an active depressurization system to effectively treat potential structural vapor intrusion.

H&H connected RadonAway RP-265 fans, which are standard electric radon-style fans, to the
vertical riser piping to model an active depressurization system. Differential pressure
measurements were collected at each vacuum monitoring point using a Dwyer series 475 Mark III
Digital manometer (capable of measuring to 0.001 in-WC or 0.25 Pa) to establish baseline
conditions prior to use of the electric fans. Following collection of baseline differential pressure
measurements, the electric fans were turned on and differential pressure measurements were
collected at each monitoring point over varied time intervals. Results of the influence tests
indicated sub-slab vacuum measured at the monitoring points ranged from -0.113 in-WC to -2.152
in-WC.

Results of the influence tests are summarized in Table E-1 (Building 1010), Table E-2 (Building
1011), and Table E-3 (Building 1012) included in Appendix E. In every unit, the measured
vacuum at the monitoring point was above the minimum 0.016-in-WC. The influence tests
demonstrate adequate sub-slab system communication and that sufficient vacuum can easily be
achieved below the slab of each unit. The locations of the permanent monitoring points (denoted
by MP nomenclature) are shown on Sheets VM-2A, VM-2B, and VM-2C (Appendix C).

3.0 Sub-Slab Soil Gas Assessment Activities

Following successful installation of the VIMS, H&H collected sub-slab soil gas samples for
laboratory analysis from each building in the following units:

• Building 1010 – Samples SS-1010-A (Unit A), SS-1010-E (Unit E), and SS-1010-H (Unit
H)
• Building 1011 – Samples SS-1011-A/SS-1011-DUP (Unit A), SS-1011-E (Unit E), and
SS-1011-H (Unit H)
• Building 1012 – Samples SS-1012-A (Unit A), SS-1012-D (Unit D), and SS-1012-G
(Unit G)

The sub-slab assessment activities were conducted in accordance with the DEQ-approved VIMP
and DEQ Division of Waste Management (DWM) Vapor Intrusion Guidance (Guidance) dated
March 2018.

3.1 Sub-Slab Soil Gas Sampling

On March 3, 2022, H&H collected sub-slab soil gas samples from permanent monitoring points in
Buildings 1010, 1011, and 1012. The sampling was performed following VIMS installation
activities and a minimum of two weeks after installation of the turbine ventilators. The sub-slab
soil gas samples were collected from permanent monitoring points corresponding to the units
above and as shown on Sheets VM-2A, VM-2B, and VM-2C (Appendix C). One duplicate sub-
slab soil gas sample (SS-1011-DUP) was collected for quality assurance/quality control (QA/QC)
purposes during the event concurrent with the SS-1011-A parent sample. The duplicate sample
was collected utilizing a laboratory supplied stainless-steel sampling “T” which allows for the
simultaneous collection of two sub-slab soil gas samples from a single location.

To collect the sub-slab soil gas samples, Teflon sample tubing was secured to a 2-inch expandable
well cap with a sampling port that was secured onto the 2-inch diameter PVC monitoring point.
The tubing was connected to an airflow regulator and laboratory-supplied batch-certified 1-liter

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/nvr, inc/nvr-010 opr/bldg completion reports/buildings 10, 11, 12/report/10061_vims install_buildings 1010, 1011, & 1012_opr.docx
stainless steel Summa canister. The air flow regulator was preset by the laboratory to collect a soil
gas sample at a flow rate of approximately 100 milliliters per minute.

Prior to sample collection, H&H conducted a leak test at each monitoring point by placing a shroud
around the monitoring point, expandable well cap, and sampling train including the Summa
canister. The air within the shroud was flooded with helium gas and concentrations were measured
with a calibrated helium detector. Helium concentrations within the shroud were maintained at
approximately 15% to 20%. A GilAir vacuum pump was connected to the sample tubing outside
of the shroud and used to purge a minimum of three volumes (monitoring point and sample train)
of soil gas into a Tedlar® bag at each sampling point. The helium gas detector was used to measure
helium concentrations within the Tedlar bag sample to confirm helium concentrations in the
sample were less than 10% of that measured within the shroud. Results of the helium leak checks
indicate that helium was not detected in the purge air, which indicates short-circuiting at the
monitoring points or within the sampling train. Soil gas sampling field forms completed by
sampling personnel are included in Appendix E.

Following a successful leak check, the air flow regulators were opened to allow collection of the
sub-slab soil gas samples. Vacuum in the Summa canisters was monitored during the sampling
event to confirm adequate sample volume was collected at each monitoring point location. Upon
completion of sample collection, the air flow regulator was closed to the Summa canister. The
canisters were labeled with the sample identification, beginning and ending times and pressure
measurements, and the requested analysis. The canisters were then placed in laboratory supplied
shipping containers and delivered to Pace Analytical Laboratories (Pace) under standard chain of
custody protocols for analysis of volatile organic compounds (VOCs) by EPA Method TO-15.

3.2 Sub-Slab Soil Gas Sampling Results

The sub-slab soil gas sample analytical results are summarized in Table 1. The results were
compared to the DEQ DWM Residential Vapor Intrusion Sub-Slab and Exterior Soil Gas
Screening Levels (SGSLs) dated January 2022. The laboratory analytical report and chain of
custody record is provided as Appendix F.

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/nvr, inc/nvr-010 opr/bldg completion reports/buildings 10, 11, 12/report/10061_vims install_buildings 1010, 1011, & 1012_opr.docx

The sub-slab soil gas sample analytical results indicate that several compounds were detected in
each sample above laboratory method detection limits. With the exception of naphthalene in sub-
slab sample SS-1011-E (6.5 µg/m3), no compounds were detected above the Residential SGSLs.

The DEQ DWM Vapor Intrusion SGSLs are very conservative and based on a target carcinogenic
risk (TCR) for potential carcinogenic risks of 1 x 10-6 and a hazard quotient (HQ) of 0.2 for
potential non-carcinogenic risks. The DEQ and EPA acceptable risk level for potential
carcinogenic risks is a cumulative lifetime incremental cancer risk (LICR) of 1 x 10-4 or less and
the acceptable level for non-carcinogenic risks is a cumulative hazard index (HI) of 1 or less. The
HI is the sum of HQs for each target analyte.

H&H utilized the DEQ Risk Calculator (January 2022) to confirm there are no potential vapor
intrusion risks at unacceptable levels. H&H modeled a worst-case scenario by using the highest
concentrations of any compound detected below each building under a residential use scenario to
conservatively evaluate potential vapor intrusion risks. The calculated LICR and HI for each
building are included below:

• Worst-case residential use calculations for Building 1010 indicate a calculated LICR of 2.4
x 10-7 and a calculated HI of 0.086;
• Worst-case residential use calculations for Building 1011 indicate a calculated LICR of 2.7
x 10-6 and a calculated HI of 0.095; and,
• Worst-case residential use calculations for Building 1012 indicate a calculated LICR of
7.1 x 10-7 and a calculated HI of 0.096.

These risk calculator results indicate the LICR and HI values are orders of magnitude below the
DEQ and EPA acceptable levels. The calculated LICR and HI values are included in Table 1 and
copies of the DEQ Risk Calculators are included as Appendix G.

4.0 Summary and Conclusions

Construction of townhome Buildings 1010, 1011, and 1012 of the Old Pineville Townhomes
development has been completed at the Old Pineville Road Brownfields property (Brownfields
Project No. 10061-06-060) located at in Charlotte, North Carolina. The Old Pineville Townhomes
project includes construction of 15 total buildings at the Site, and separate reports will be submitted
to document installation of the VIMS in the other buildings.

During construction of the buildings, H&H conducted VIMS installation inspections to confirm
the system was installed as designed and completed post-installation sub-slab soil gas sampling
activities to evaluate efficacy of the system. The VIMS installation inspections and post-
installation sampling activities were completed in general accordance with the DEQ-approved
VIMP. The PD and/or HOA will be responsible for future maintenance of the VIMS to maintain
system effectiveness. A brief summary of the VIMS installation and post-installation soil gas
assessment activities is provided below.

VIMS Installation
VIMS installation has been completed for Buildings 1010, 1011, and 1012 and consists of a passive
sub-slab depressurization system with vertical extraction piping to the roof and enhanced with
wind-driven turbine ventilators installed above the building roofline. A modification was made to
the VIMP and approved by the design engineer (a NC Professional Engineer) in Building 1012 in
which soil gas collector mat was substituted for the slotted sub-slab PVC. In addition, wind-driven
turbines were installed at the roof discharge of all three buildings in place of the Syphon
ventilators. During installation of the VIMS, H&H personnel, under direction of a NC Professional
Engineer, conducted inspections during each stage of installation. Results of the installation
inspections indicate that the VIMS was successfully installed in general accordance with the DEQ-
approved VIMP, with the exception of the soil gas collector mat and turbine modifications.
Influence testing for the buildings confirmed sub-slab VIMS communication and that adequate
vacuum can be obtained should an active depressurization system be warranted in the future.

Sub-Slab Soil Gas Assessment
Following installation of the VIMS and completion of interior construction activities, H&H
collected sub-slab soil gas samples from Buildings 1010, 1011, and 1012 to evaluate potential
vapor intrusion risks. Laboratory analytical results of the sub-slab soil gas samples indicate that
multiple VOCs were detected in the sub-slab of each building. Naphthalene was detected in one
sample (SS-1011-E) at a concentration above the DWM Residential Vapor Intrusion SGSLs,
however no other compounds were detected above the Residential SGSLs.

H&H utilized the DEQ Risk Calculator (January 2022) to calculate the cumulative carcinogenic
and non-carcinogenic risks under a hypothetical worst-case residential use scenario by utilizing
the highest concentration of each compound detected in the sub-slab soil gas samples from each
building. The hypothetical worst-case residential use risk calculator results indicate the calculated
LICR and HI are well below DEQ and EPA acceptable risk levels.

Based on the VIMS installation inspections, influence testing, and post-installation sub-slab soil
gas sampling results, the VIMS is effectively mitigating potential vapor intrusion risks at the Site.
The sub-slab soil gas to indoor air risk calculator results confirm that risks are below acceptable
levels. In accordance with the DEQ-approved VIMP, two post-construction sub-slab soil gas
sampling events will be completed on an annual basis.

PRODUCT PART #
VaporBlock® Plus™ 20 ................................................................ VBP20
UNDER-SLAB VAPOR / GAS BARRIER
Under-Slab Vapor/Gas Retarder
© 2018 RAVEN INDUSTRIES INC. All rights reserved.
VAPORBLOCK® PLUS™VBP20
PRODUCT DESCRIPTION
VaporBlock® Plus™ is a seven-layer co-extruded barrier
made using high quality virgin-grade polyethylene and
EVOH resins to provide unmatched impact strength as well
as superior resistance to gas and moisture transmission.
VaporBlock® Plus™ 20 is more than 100 times less permeable
than typical high-performance polyethylene vapor retarders
against Methane, Radon, and other harmful VOCs. Tested and
verified for unsurpassed protection against BTEX, HS, TCE, PCE,
methane, radon, other toxic chemicals and odors.
VaporBlock® Plus™ 20 multi-layer gas barrier is manufactured
with the latest EVOH barrier technology to mitigate hazardous
vapor intrusion from damaging indoor air quality, and the safety
and health of building occupants. VBP20 is one of the most
effective underslab gas barriers in the building industry today
far exceeding ASTM E-1745 (Plastic Water Vapor Retarders
Used in Contact with Soil or Granular Fill Under Concrete Slabs)
Class A, B and C requirements. Available in a 20 (Class A) mil
thicknesses designed to meet the most stringent requirements.
VaporBlock® Plus™ 20 is produced within the strict guidelines
of our ISO 9001 Certified Management System.
PRODUCT USE
VaporBlock® Plus™ 20 resists gas and moisture migration
into the building envelop when properly installed to provide
protection from toxic/harmful chemicals. It can be installed as
part of a passive or active control system extending across the
entire building including floors, walls and crawl spaces. When
installed as a passive system it is recommended to also include
a ventilated system with sump(s) that could be converted to an
active control system with properly designed ventilation fans.
VaporBlock® Plus™ 20 works to protect your flooring and
other moisture-sensitive furnishings in the building’s interior
from moisture and water vapor migration, greatly reducing
condensation, mold and degradation.
SIZE & PACKAGING
VaporBlock® Plus™ 20 is available in 10’ x 150’ rolls to
maximize coverage. All rolls are folded on heavy-duty cores
for ease in handling and installation. Other custom sizes
with factory welded seams are available based on minimum
volume requirements. Installation instructions and ASTM E-1745
classifications accompany each roll.

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)

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

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

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

INSTALLATION INSTRUCTIONS
1. Begin work on the sub grade (soil or gravel) after the final preparation and
before the concrete is poured. Start with T-Riser(s) and work out to ensure
smooth mat placement. Position the T-Riser(s) in appropriate location(s) and
nail down with a 12” steel nail (T Nail) through precut center hole.
2. Slide mat into flat openings on either end of T-riser with a portion of the fab-
ric around the outside. Tape the fabric to the outside of the T-Riser with duct
tape and staple mat to the ground with landscape staples to ensure soil contact
remains during pour stage.
3. Mat is typically laid out in a rectangular loop in the largest area with branch-
es or legs into smaller areas (FREE plan design at www.radonmat.com). There
is no need to trench the mat. Roll out the SGC mat, smooth it onto the ground.
To avoid wrinkles and buckling, work away from the risers, stapling to the
ground as you go. The mat should be stapled every three to four feet, in addi-
ton to corners, tee junctions & ends.
5. Corners are constructed by peeling back the filter fabric, cutting two ends
of the matrix at 45 degree angles and butting (or overlapping: no more than
1/2”) the matrix together. Pull the filter fabric back and tape into place. Staple
across the joint of the matrix and each leg of the corner. Use a minimum of
four staples at each corner-- two across the joint and one on each leg.
6. The tees for branches and legs are constructed by slitting the fabric of the
main loop at the location desired. Cut the fabric of the branch at the edges and
expose two inces of the matrix. Cut off the exposed matrix and but the ma-
trix of the branch (or overlap 1/2”)to the matrix of hte main loop. Pull the flter
fabric of the branch back over the main loop and tape into place. Staple across
joint of the matrix with two staples and one each on the branch and main loop.
Use a minimum of four staples at each tee, two across the joint and one on
each loop and branch.
4
7. All openings in the fabric at joints, tee’s, and ends of branches should be
taped to keep out concrete.
8. Stub up a few feet of 4” schedule 40 PVC* from all T risers before pour (or
cover T riser with duct tape). Seal with polyurethene caulk and screws. This
ensures no concrete aggregate enters the riser during slab pour. Be sure to
label “CAUTION RADON REDUCTION SYSTEM” on all pipe. *(6” PVC may be
substituted--for large multifamily projects. Simply cut T riser 4” insert away to
reveal 6” insert).
9. When the building is ready for the vent pipe to be installed above the slab,
fit to pre-stubbed PVC with PVC straight connect. If PVC was not preset, cut
duct tape from riser and insert 4” PVC pipe now. Seal with polyurethene caulk
and secure with screws. Always label “CAUTION RADON REDUCTION SYSTEM”
to avoid confusion on site and for the building occupants.
note: The openings in the riser are laid out at 180 degrees to accomodate
straight runs of mat. However, if the riser is to be placed in a corner, which is
not uncommon, the front of the T can be cut and the SGC mat inserted into
the new opening. The side of the T that is unused should be sealed with tape.
This creates a 90 degree T which will allow corner placement for the riser. Mat
should always enter the T riser from at least two directions and exhaust to pipe
vertically.
SAFETY DATA & PRODUCT DATA SHEETS AVAILABLE @ www.RADONMAT.com 5
MAKING CORNERS AND SPLICES
The mat should be routed around the inside perimeter of the foundation. This
will require occasional corner junctions. Furthermore, splices will have to be
made to join two lengths of mat together. Corners and splices are very easy to
make, and do not require any special fittings. Cut back the filter fabric to reveal
the core material. In the case of a splice, merely overlap the core by at least
one corrugation, replace the cloth, and tape it. Use two landscape staples to
hold the splice in place. In the case of a corner, peel back geotextile fabric and
slice the core of the two adjoining legs at 45 degree angles which mirror each
other; overlap the edges by one corrugation; return grey geotextile fabric, tape
and staple the corner together.

CONNECTING THE MAT TO THE
T RISER
A convenient T-riser with dual entry al-
lows for either end of the loop of mat
to be secured to the riser. Slide the
mat into each end of the riser and tape
the edge to prevent wet concrete from
entering. Cap the riser to ensure no
concrete enters. T Riser caps can be
purchased in leui of duct tape. A pres-
tub of PVC pipe can also serve the same
purpose. See steps 8-9 of the previous

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