VIMS Installation Completion Report Old Pineville Road
Old Pineville Road Townhomes – Buildings 1005 & 1006 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 Buildings 1005 and 1006, each with eight units (Units A through H). Building 1005
and 1006 are located in the eastern central portion of the Site. A Site location map is provided as
Figure 1, and a Site Map that identifies the Site buildings 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

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/nvr, inc/nvr-010 opr/bldg completion reports/building 1005 and 1006/10061_vims install_building 1005 & 1006_opr.docx
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 1005 and 1006. 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 1005 and 1006 each consist of eight individually owned 3-story townhomes. The
buildings are built with thickened concrete footers and block walls with a concrete slab on-grade
foundation. The concrete footings and block walls were constructed prior to the slab-on-grade.
Each building 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 slabs 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
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. 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

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/nvr, inc/nvr-010 opr/bldg completion reports/building 1005 and 1006/10061_vims install_building 1005 & 1006_opr.docx
the vapor through exhaust stacks above the building roof. The passive VIMS is also enhanced
with an Empire Eveco EV04SS (stainless steel) stationary ventilator that is designed to promote
air exhaust from the conveyance piping. The Empire Eveco 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 vent piping, riser conveyance piping, and a stationary ventilator.
Product specification sheets for the ventilator and slotted piping 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
movement beneath the entirety of the slab. Sub-slab vapor collection piping (3-inch diameter) was
installed within the high permeability stone layer. The thickness of the high permeability stone
around the piping extends a minimum of 1-inch above the piping and a minimum of 1-inch below
the sub-slab piping (approximately 5-inches of gravel around a 3-inch pipe). In areas without sub-
slab piping, a minimum thickness of 4 inches of clean stone was installed.

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 1005 and 1006, 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 piping 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 stationary ventilator installations.

Based upon inspections completed during the VIMS installation activities, the VIMS was installed
in general accordance with the DEQ-approved VIMP. 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
In May and June 2021, H&H completed influence testing for Buildings 1006 and 1005,
respectively, 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), 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 are
summarized in Table E-1 (Building 1005) and Table E-2 (Building 1006). 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-2 and VM-3 (Appendix C). The pilot
test field data forms are included in Appendix E.

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 at the following locations:
• Building 1005 – Samples SS-1005-A (Unit A), SS-1005-D (Unit D), and SS-1005-H (Unit
H)
• Building 1006 – Samples SS-1006-A (Unit A), SS-1006-D (Unit D), SS-1006-H (Unit H).

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 September 24, 2021, H&H collected sub-slab soil gas samples from permanent monitoring
points in Buildings 1005 and 1006. The sampling was performed following VIMS installation
activities and a minimum of two weeks after installation of the stationary ventilator. The sub-slab
soil gas samples were collected from the permanent monitoring points corresponding to the units
above and as shown on Sheets VM-2 and VM-3 (Appendix C). One duplicate sub-slab soil gas
sample (SS-1006-DUP) was collected for quality assurance/quality control (QA/QC) purposes
during the event concurrent with the SS-1006-H 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
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 10% to 15%. 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 were not present. 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 Waypoint Analytical 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 June 2021. The laboratory analytical report and chain of custody
record is provided as Appendix F.

The sub-slab soil gas sample analytical results indicate that several compounds were detected in
each sample above laboratory method detection limits. Ethylbenzene was detected in sub-slab

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/nvr, inc/nvr-010 opr/bldg completion reports/building 1005 and 1006/10061_vims install_building 1005 & 1006_opr.docx
sample SS-1005-D at a concentration of 141 µg/m3, which exceeds the Residential SGSL.
Ethylbenzene was not detected above the Residential SGSL in any other sample, and no other
compounds were detected at concentrations above DEQ DWM Residential Vapor Intrusion SGSLs
in any of the sub-slab soil gas samples from Buildings 1005 and 1006.

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 (June 2021) 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 1005 indicate a calculated LICR of 6.6
x 10-6 and a calculated HI of 0.32; and,
• Worst-case residential use calculations for Building 1006 indicate a calculated LICR of 2.3
x 10-6 and a calculated HI of 0.074.

The results of the worst-case risk calculations confirm that compound concentrations detected
below the building slabs do not pose vapor intrusion risks at unacceptable levels within the
townhome units at Buildings 1005 and 1006. The calculated cumulative LICR and HI values are
provided in Table 1and copies of the completed DEQ Risk Calculators are provided in
Appendix G.

4.0 Summary and Conclusions

Construction of townhome Buildings 1005 and 1006 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 1005 and 1006 and consists of a passive sub-
slab depressurization system with vertical extraction piping to the roof and enhanced with
stationary ventilators installed above the building roofline. During installation of the VIMS, H&H
personnel, under direction of a North Carolina licensed 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.
Influence testing for the buildings confirmed efficient 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 1005 and 1006 to evaluate potential vapor
intrusion risks. Laboratory analytical results of the sub-slab soil gas samples indicate that only
ethylbenzene was detected in one sample (SS-1005-D) at a concentration above the DEQ DWM
Residential Vapor Intrusion SGSL. H&H utilized the DEQ Risk Calculator (June 2021) 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 values for each building 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

Product Specifications

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.

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

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

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

Option 2
VAPORBLOCK® PLUS™ REPAIR INSTRUCTIONS
1.7. Proper installation requires all holes and openings are repaired prior
to placing concrete. When patching small holes, simply cut a 12” long
piece of 12” wide VaporSeal™ tape. Remove release liner and center
over the opening. Apply pressure to create a seal (Fig. 14-15).
1.8. When installing VaporBlock® Plus™ around pipe penetrations,
vertical columns, electrical ducts and other obstructions, you will
find it necessary to cut it to the nearest outside edge. This cut can
be easily sealed with 12” wide VaporSeal™ tape, by simply centering
it over the cut, 6” on either side. Once the tape is placed correctly,
apply pressure to assure a complete seal (Fig. 16).
Reminder Note: All holes or penetrations through the membrane will need
to be patched with 12” VaporSeal™ Tape.
Fig. 14
Page 4 of 5
Fig. 15
2.1. When installing reinforcing steel and utilities, in addition to the
placement of concrete, take precaution to protect VaporBlock®
Plus™. Carelessness during installation can damage the most
puncture–resistant membrane. Sheets of plywood cushioned with
geotextile fabric temporarily placed on VaporBlock® Plus™ provide
for additional protection in high traffic areas including concrete
buggies.
2.2. Use only brick-type or chair-type reinforcing bar supports to protect
VaporBlock® Plus™ from puncture.
2.3. Avoid driving stakes through VaporBlock® Plus™. If this cannot be
avoided, each individual hole must be repaired per section 1.7.
2.4. To avoid penetrating VaporBlock® Plus™ when installing screed
supports, utilize non-penetrating support, such as the Mako®
Screed Support System (Fig. 17). Avoid driving stakes through
VaporBlock® Plus™. If this cannot be avoided, each individual hole
must be repaired per figures 14-15.
2.5. If a cushion or blotter layer is required in the design between
VaporBlock® Plus™ and the slab, additional care should be given if
sharp crushed rock is used. Washed rock will provide less chance of
damage during placement. Care must be taken to protect blotter layer
from precipitation before concrete is placed.

VAPOR INTRUSION MITIGATION SYSTEM (VIMS) SPECIFICATIONS
1.THIS VAPOR INTRUSION MITIGATION PLAN IS INTENDED TO BE USED FOR DIRECTION OF VIMS COMPONENT INSTALLATION ONLY AND IS NOT INTENDED TO GUIDE CONSTRUCTION OF STRUCTURAL COMPONENTS NOT RELATED TO THE VIMS. CONSTRUCTION CONTRACTOR
SHALL VERIFY CONSISTENCY OF VIMS DETAILS WITH APPLICABLE STRUCTURAL, ARCHITECTURAL, MECHANICAL, AND PLUMBING PLANS AND RESOLVE INCONSISTENCIES WITH THE DESIGN ENGINEER PRIOR TO VIMS INSTALLATION.
2.CONSTRUCTION CONTRACTORS AND SUB-CONTRACTORS USED "LOW OR NO VOC" (INCLUDING NO PCE OR TCE) PRODUCTS AND MATERIALS, WHEN POSSIBLE. THE CONSTRUCTION CONTRACTOR AND SUB-CONTRACTORS PROVIDED SAFETY DATA SHEETS (SDS) TO THE
ENGINEER FOR PRODUCTS AND MATERIALS USED DURING CONSTRUCTION.
VIMS VAPOR LINER IS VAPORBLOCK PLUS 20 VAPOR BARRIER MANUFACTURED BY RAVEN INDUSTRIES.
THE VAPOR LINER WAS INSTALLED AS SPECIFIED HEREIN AND PER MANUFACTURER INSTALLATION INSTRUCTIONS TO CREATE A CONTINUOUS LINER BELOW GROUND FLOOR SLABS. A BASE COURSE CONSISTING OF CLEAN #57 STONE (OR SIMILAR HIGH PERMEABILITY STONE
APPROVED BY THE ENGINEER) WAS INSTALLED BENEATH THE VIMS VAPOR LINER. IN AREAS AROUND THE SUB-SLAB PIPING, THE BASE COURSE LAYER IS THICK ENOUGH TO COVER THE SUB-SLAB PIPING WITH A MINIMUM 1-INCH LAYER ABOVE AND BELOW THE PIPING. IN AREAS
WITHOUT PIPING, THE BASE COURSE IS A MINIMUM OF 4-INCHES THICK.
3.ALL PENETRATIONS WERE SEALED ACCORDING TO VAPOR LINER MANUFACTURER INSTALLATION INSTRUCTIONS AS FOUND IN THE MANUFACTURER INSTALLATION GUIDELINES. SINCE VAPORBLOCK PLUS 20 WAS USED, SMALL PUNCTURE HOLES WERE SEALED WITH THE
VAPORSEALTM TAPE OR POUR-N-SEALTM AND LARGER HOLES, TEARS, OR DAMAGE WERE REPAIRED USING A PATCH THAT OVERLAPS THE DAMAGED AREA AND THEN SHALL BE TAPED ALONG THE SEAMS. IN AREAS WHERE UTILITY PENETRATIONS (I.E. PIPING, DUCTS, ETC) ARE
PRESENT AND THE USE OF TAPING IS NOT PRACTICAL OR DEEMS AS "INEFFECTIVE" BY THE DESIGN ENGINEER, POUR-N-SEALTM WAS POURED INTO FORM TO PATCH THE PENETRATION WITH AN AIR-TIGHT SEAL.
4.CONSTRUCTION CONTRACTORS AND SUB-CONTRACTORS AVOIDED THE USE OF TEMPORARY FORM BOARDS THAT PENETRATE THE VAPOR LINER WHERE POSSIBLE. IF TEMPORARY FORM BOARDS WERE USED, THE SIZE AND NUMBER OF PENETRATIONS THROUGH THE VAPOR
LINER WERE LIMITED AND SMALL DIAMETER STAKES (I.E. SOLID METAL STAKES) WERE USED. AS FORM BOARDS WERE REMOVED, THE CONTRACTOR OR SUB-CONTRACTORS SEALED PENETRATIONS IN ACCORDANCE WITH VAPOR LINER MANUFACTURER INSTALLATION
INSTRUCTIONS.
5.VIMS BELOW AND ABOVE GRADE PIPING WAS NOT TRAPPED AND WAS SLOPED A MINIMUM OF 18 UNIT VERTICAL IN 12 UNITS HORIZONTAL (1% SLOPE) TO GRAVITY DRAIN. SOLID SECTIONS OF HORIZONTAL COLLECTION PIPE WERE SUPPORTED TO PREVENT PIPE SAG OR
LOW POINT AND MAINTAIN 1% SLOPE TOWARD SLOTTED SECTIONS TO DRAIN CONDENSATION. HORIZONTAL COLLECTION PIPE SHALL CONSIST OF 3" SCH 40 PVC (OR OTHERWISE NOTED IN THE DRAWINGS). SUB-SLAB SLOTTED VAPOR COLLECTION PIPE IS THREADED FLUSH JOINT
OR GLUE JOINT 3" SCH 40 PVC PIPE WITH 0.020" SLOT WIDTH AND 18" SLOT SPACING.
6.3” SCH 40 PVC RISER DUCT PIPING EXTENDS IN A VERTICAL ORIENTATION THROUGH THE BUILDING ROOF AND TERMINATES A MINIMUM OF 1 FT ABOVE THE BUILDING ROOF LINE. EMPIRE SIPHON VENTILATORS ARE INSTALLED ON THE EXHAUST DISCHARGE END OF EACH
RISER DUCT PIPE. A 4" X 3" PVC ADAPTOR COUPLING WAS INSTALLED AT THE DISCHARGE END OF THE 3" RISER DUCT PIPE AND THE FAN WAS SECURED TO THE PVC RISER IN A VERTICAL ORIENTATION. EXHAUST DISCHARGE IS NOT LESS THAN 10 FT (IN ANY DIRECTION) FROM AIR
INTAKE OPENINGS INCLUDE WINDOWS, DOORS, AND OTHER GRAVITY AIR INTAKE OPENINGS AND EXCLUDE ATTIC VENTILATION OPENINGS.
7.NOTE THAT DISCHARGE LOCATIONS ON THE ROOFTOP DEPICTED IN THE VAPOR MITIGATION PLAN MAY HAVE BEEN REPOSITIONED AS LONG AS THE NEW POSITION MEETS THE REQUIREMENTS PRESENTED ABOVE. AN ELECTRICAL JUNCTION BOX (120V, 60HZ AC REQUIRED)
WAS INSTALLED NEAR THE FAN LOCATION FOR CONVERSION TO ELECTRIC FANS, IF REQUIRED. ALL WIRING AND ELECTRICAL WAS INSTALLED PER APPLICABLE BUILDING AND ELECTRICAL CODES.
8.ABOVE-SLAB ACCESSIBLE RISER DUCT PIPING WAS PERMANENTLY IDENTIFIED BY MEANS OF A LABEL AT A MINIMUM OF ONCE EVERY 10-LINEAR FT WITH "VAPOR SYSTEM - CONTACT HOA". THE RISER PIPE AT THE SIPHON VENTILATOR WAS LABELED WITH "VAPOR
MITIGATION SYSTEM - CONTACT HOA IF DAMAGED" IN AN ACCESSIBLE LOCATION IN THE ATTIC.
9.INSPECTIONS: INSPECTIONS OF EACH COMPONENT OF THE VIMS WERE CONDUCTED BY THE ENGINEER, OR ENGINEER'S DESIGNEE, TO CONFIRM VIMS COMPONENTS WERE INSTALLED PER THE APPROVED DESIGN. THE REQUIRED INSPECTIONS INCLUDED: (1) INSPECTION OF
SUB-SLAB PIPING LAYOUT AND GRAVEL PLACEMENT PRIOR TO INSTALLING VAPOR LINER; (2) INSPECTION OF VAPOR LINER PRIOR TO POURING CONCRETE; (3) INSPECTION OF ABOVE-GRADE PIPING LAYOUT; AND (4) INSPECTION OF FAN AND VENT PIPE CONNECTIONS. THE
CONSTRUCTION CONTRACTOR(S) COORDINATED WITH THE ENGINEER TO PERFORM THE REQUIRED INSPECTIONS. WHEN POSSIBLE. DEQ WAS CONTACTED 48-HOURS PRIOR TO THE INSPECTION BEING CONDUCTED. FIELD NOTES, PHOTOGRAPHS, AND ANY ADDITIONAL INSPECTION
DOCUMENTATION WERE INCLUDED IN THE FINAL DELIVERABLE TO DEQ.
