1.0 Introduction

On behalf of LEH NC Mint, LLC (the Prospective Developer or PD), 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 a
portion of the Quality Products Company Brownfields property (Brownfields Project No. 22016-
18-060) located at 1513 S. Mint Street and 1515 S. Mint Street in Charlotte, Mecklenburg County,
North Carolina (Site or subject Site). The Site is comprised of three tax parcels (Mecklenburg
County Parcel ID Nos. 11908315, 11908316, and 11908317) totaling approximately 0.53-acres
and is currently developed with a single-story multi-tenant commercial building with an associated
gravel-covered parking area.

Proposed redevelopment plans for the Site include upfit and renovations for adaptive re-use of the
existing building including spaces for a restaurant and a dentist office. The remainder of the Site
will generally be covered with impervious surfaces including parking areas, sidewalks and exterior
patios. Renovation of the 1515 S. Mint Street tenant space is currently in progress and occupancy
for the space is anticipated in mid-August. The 1513 S. Mint Street tenant space has yet to begin
upfit activities and a separate VIMS Installation Completion Report will be submitted for this
space once installation and post-construction sampling are completed. A redevelopment Site plan
is included in Figure 1.

H&H previously completed vapor intrusion assessment activities at the Site to evaluate the
potential for vapor intrusion prior to redevelopment. Results of previous vapor intrusion
assessment activities are documented in our Limited Phase II Environmental Site Assessment
(ESA) Report (dated March 2, 2018), and the Brownfields Assessment Report (dated October 22,
2
S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report
2019). Tabular summary of the vapor intrusion assessment sample results and sample location
maps are provided in Appendix A for ease of reference.

In addition, H&H conducted a baseline mercury sub-slab soil gas assessment at the site to establish
pre-mitigation baseline mercury vapor concentrations. Results of the mercury vapor assessment
are documented in H&H’s Mercury Vapor Assessment Report (dated October 27, 2020). During
the assessment, four sub-slab samples were collected. Mercury was not detected in three of the
samples, and was detected at an estimated concentration at one location (SSV-3, 0.52 µg/m3) well
below the DEQ DWM Non-Residential Vapor Intrusion Soil Gas Screening Level of 26 µg/m3.
Based on these concentrations, H&H recommended no further assessment of mercury vapor on
the site. DEQ found the findings in the above report to be in compliance with the Vapor Intrusion
Mitigation Plan for the property in a Mercury Assessment Report Compliance Review dated
December 3, 2020.

The draft Brownfields Agreement for the Site includes the following land use restriction (LUR)
No. 15.g.:

No enclosed building may be constructed on the Brownfields Property and no existing building,
defined as those depicted on the plat component of the Notice of Brownfields Property, may be
occupied until DEQ determines in writing that:
i. the building is or would be protection of the building’s users, public health and the
environment from risk of vapor intrusion based on site assessment data or a site-specific
risk assessment approved in writing by DEQ; or
ii. the building is or would be sufficiently distant from the Brownfields Property’s
groundwater and/or soil contamination based on assessment data approved in writing by
DEQ that the building’s users, public health and the environment will be protected from
risk from vapor intrusion related to said contamination; or
iii. vapor mitigation measures are installed or implemented to the satisfaction of a
professional engineer licensed in North Carolina, as evidenced by said engineer’s
profession seal on a report that includes photographs and a description of installation and
performance of said measures. Any design specification for vapor intrusion mitigation
3
S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report
measured shall be approved in writing by DEQ in advance of installation and/or
implementation of said measures. The design specifications shall include
methodology(ies) for demonstrating performance of said measures.
In accordance with the LUR No. 15.g., the DEQ Brownfields Program approved Environmental
Management Plan (EMP) dated October 29, 2019, and conversations with DEQ Brownfields
personnel in a meeting held on October 7, 2019, the PD has elected to install a vapor intrusion
mitigation system (VIMS) in the Site building.

The DEQ-approved Vapor Intrusion Mitigation Plan (VIMP), dated August 3, 2020 includes
installation of a passive sub-slab depressurization system in the 1513 and 1515 S. Mint Street
building and post-installation sub-slab soil gas sampling. This report documents installation of the
VIMS and post-construction sub-slab soil gas assessment for the 1515 S. Mint Street tenant space.

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

2.1 VIMS Installation

The DEQ-approved VIMP includes installation of a 20-mil tape-sealed vapor barrier. On August
2, 2021, DEQ approved via email the installation of the spray-sealed vapor barrier Geo-Seal®
EV20 manufactured by EPRO Services, Inc. (EPRO) in lieu of the vapor barrier specified in the
approved VIMP. The vapor barrier was installed above the base course layer and beneath the
concrete. Geo-Seal® EV20 is an ASTM-certified 20-mil, multi-layer, chemically resistant vapor
barrier, designed to minimize the migration of volatile organic compounds (VOCs). The vapor
barrier was installed per manufacturer installation instructions by S&H, a certified Geo-Seal®
system installation contractor. Technical specifications and installation instructions obtained from
EPRO for the Geo-Seal® EV20 vapor barrier and associated accessories are provided as Appendix
B.

Geo-Seal® EV20 was installed to cover the base course layer below the slab area of the proposed
ground floor slab. The vapor barrier was attached/sealed to concrete and masonry surfaces of
footings and existing walls (see Sheet VM-2). Geo-Seal CORE was used to attach/seal the vapor
barrier to concrete or masonry surfaces. Seams within the building footprint have a minimum 6-
inch overlap and were sealed with Geo-Seal CORE or Geo-Seal CORE Detail. Small puncture
holes were sealed with Geo-Seal CORE or Geo-Seal CORE Detail. Larger holes, tears, or other
damage were repaired using a patch of vapor barrier that overlaps the damaged area a minimum
of 6” and have a minimum 60 mil application of Geo-Seal CORE in the seam overlap.

The VIMP also includes installation of a passive mitigation system beneath the slab of the 1515 S.
Mint Street building to reduce the potential for structural vapor intrusion into the non-residential
space. The passive system includes a polyvinyl chloride (PVC) piping network below the slab of
the building. Three vertical exhaust risers that extend to the roof of the building were connected
to the sub-slab piping network. Empire Model TV04SS (stainless steel) wind-driven turbine fans
were installed in-line with the risers on the roof of the building to enhance passive vapor mitigation
and discharge sub-slab vapors to the atmosphere above the roof of the building. The VIMS layout
5
S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report
is shown in the as-built drawings (Sheets VM-1 and VM-2) included as Appendix C. Product
specification sheets for the turbine fans and sub-slab piping are included in Appendix D.

To enhance sub-slab vapor transmission and collection effectiveness, a uniform layer of high
permeability stone (#57 stone) was installed directly below the concrete slab to allow for air
movement beneath the entirety of the slab. Sub-slab vapor collection piping (4-inch diameter) was
installed completely within the high permeability stone layer.

The VIMP also includes three vacuum monitoring points (depicted on the as-built sheets in
Appendix C). The vacuum monitoring points were used to measure the pressure differential
between ambient air and the sub-slab during influence testing activities described below, and for
collection of sub-slab soil gas samples.

During installation of the VIMS in the 1515 S. Mint Street tenant space, H&H conducted
inspections during various phases of construction to confirm the VIMS was installed in accordance
with the DEQ-approved VIMP. Inspections were completed during the following phases of
installation:
• after installation of sub-slab horizontal collection piping system within the gravel base;
• following placement and sealing of the vapor barrier, during smoke testing, and prior to
pouring the concrete building slab;
• after installation of vertical exhaust riser pipe and turbine fan installations; and
• following utility upfit activities, inspection of the gravel layer and repaired barrier

On June 15, 2022, following installation of the concrete slab, H&H was notified of sub-slab
utilities requiring upfit which would involve penetrating the concrete slab and the vapor barrier.
To ensure proper repairs to the VIMS, H&H conducted inspections throughout the repair process.
An inspection of the gravel layer was conducted following the sub-slab upfit repairs to confirm
that clean # 57 stone was present. The certified installers then repaired the Geo-Seal® EV20 vapor
barrier per the manufacturer’s installation instructions. Following completed barrier repair
activities, H&H conducted a final inspection of the vapor barrier to confirm that all areas were
properly sealed to prevent preferential pathways through the slab.

Based upon periodic inspections completed during VIMS installation activities, the VIMS was
installed in 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
photographic log of installed VIMS components is provided in Appendix E.

2.2 VIMS Influence Testing

On May 2, 2022, H&H completed influence testing for the system to evaluate sub-slab vacuum
communication and to document sufficient depressurization can be obtained below the slab should
the system be activated with electric fans in the future (if warranted). 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.

VIMS vacuum influence pilot testing included use of AMG Eagle Extreme electric fans 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 0.001 in-WC or 0.25 Pa) to establish baseline conditions prior to operation of the AMG
Eagle Extreme 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. Results of the influence tests indicated sub-slab vacuum measured at the
monitoring points ranged from 0.170 in-WC to 0.338 in-WC in the tenant space, which
demonstrates sufficient vacuum can be achieved below the slab of each of this portion of the
building. The locations of the permanent monitoring points (denoted by MP nomenclature) are
shown in VM-1 (Appendix C). The pilot test field data is included in Appendix F.
3.0 Sub-Slab Soil Gas Assessment Activities

Following successful installation of the VIMS, H&H collected two sub-slab soil gas samples for
laboratory analysis from the 1515 S. Mint Street tenant space. The sub-slab assessment activities
were conducted in accordance with the DEQ-approved VIMP and the DEQ DWM Vapor Intrusion
Guidance (Guidance) dated March 2018.

3.1 Sub-Slab Soil Gas Sampling
On June 1, 2022, H&H collected two sub-slab soil gas samples from permanent monitoring points
in the 1515 S. Mint Street tenant space. The sampling was performed following VIMS installation
activities and over two weeks after both completion of the riser piping and installation of the wind-
driven turbine fans. The sub-slab soil gas samples were collected from permanent monitoring
point locations MP-1 and MP-3, as shown on VM-1 in Appendix C. One duplicate sub-slab soil
gas sample (MP-DUP) was collected for quality assurance/quality control (QA/QC) purposes from
the MP-3 parent location during the sampling event. 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 PVC monitoring point. The tubing was
connected to an airflow regulator and laboratory-supplied batch-certified 1.4-liter stainless steel
Summa canister. The air flow regulator was preset by the laboratory to collect a soil gas sample
over a period of 10 minutes.

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
between approximately 15.8% and 16.9%. 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 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 F.

S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report
Following successful leak checks, 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, pressure
measurements, and the requested analysis. The canisters were then placed in laboratory supplied
shipping containers and delivered to Waypoint Analytical Laboratories (Waypoint) 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 with chain of
custody record is provided as Appendix G.

The monitoring point soil gas sample analytical results indicate that several compounds were
detected at concentrations above laboratory method detection limits (MDLs) in each sample, but
below the DEQ DWM Residential and Non-Residential Vapor Intrusion SGSLs. Naphthalene was
detected at concentrations above DEQ DWM Residential Vapor Intrusion SGSLs but below Non-
Residential Vapor Intrusion SGSLs in samples MP-3 and MP-DUP. Trichloroethene (TCE) was
detected at concentrations above DEQ DWM Residential Vapor Intrusion SGSLs but below Non-
Residential Vapor Intrusion SGSLs in sample MP-1. TCE was also detected at concentrations
above DEQ DWM Non-Residential Vapor Intrusion SGSLs in samples MP-3 and MP-DUP. No
other compounds were detected above DEQ DWM Residential or Non-Residential Vapor Intrusion
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
9
S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report
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 that 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 the slab in the 1515 S. Mint Street tenant space
based on a non-residential use scenario to conservatively evaluate potential vapor intrusion risks.
The calculated cumulative LICR and HI values are provided in Table 1, and a copy of the
completed DEQ Risk Calculator is provided in Appendix H.

As shown in Table 1, results of the worst-case risk calculations indicate a calculated cumulative
LICR of 1.9 x 10-6 and a HI value of 0.38. The calculated cumulative residential use LICR and
HI values are within the DEQ and EPA acceptable levels. These risk calculator results confirm
that compound concentrations detected below the slab do not pose vapor intrusion risks at
unacceptable levels within the 1515 S. Mint Street tenant space with a passive VIMS.

4.0 Summary and Conclusions

Upfit of the 1515 S. Mint Street tenant space has been completed at the Quality Products Company
Brownfields property (Brownfields Project No. 22016-18-060) located in Charlotte, Mecklenburg
County. The 1513 S. Mint Street tenant space has not yet been redeveloped and a separate report
will be submitted to document installation of the VIMS in this space once complete.

During redevelopment of the space, 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. 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 1515 S. Mint Street tenant space and consists of a
passive sub-slab depressurization system with vertical extraction piping to the roof connected to
wind-driven turbine fans. 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 space
confirmed that adequate vacuum is obtainable for the purpose of active vapor mitigation (if
warranted in the future).

Sub-Slab Vacuum
H&H completed vacuum influence pilot testing in May 2022 following installation of the VIMS
piping network, but prior to installation of the wind-driven fans. Vacuum measurements collected
during the pilot testing activities (range from 0.170 in-WC to 0.338 in-WC) indicated that vacuum
communication beneath the slab was achieved with adequate differential pressure levels.

S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report
Sub-Slab Soil Gas Assessment
Following installation of the VIMS and completion of interior construction activities, H&H
collected three sub-slab soil gas samples from the 1515 S. Mint Street tenant space to evaluate
potential vapor intrusion risks. Laboratory analytical results of the sub-slab soil gas samples
indicate that naphthalene and TCE were detected at concentrations above the DEQ DWM
Residential Vapor Intrusion SGSLs in samples MP-3/DUP and MP-1, respectively. TCE was also
detected above DEQ DWM Non-Residential Vapor Intrusion SGSLs in samples MP-3/DUP.
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 tenant space sub-slab soil gas samples.
Although TCE was detected above DEQ DWM Non-Residential Vapor Intrusion SGSLs in
samples MP-3/DUP, hypothetical worst-case non-residential use risk calculator results indicate a
calculated cumulative LICR of 1.9 x 10-6 and a calculated cumulative HI of 0.38. The calculated
cumulative residential use LICR and HI values are within the DEQ and EPA acceptable 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.

Appendix B
Geo-Seal EV20s Submittal Package

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

Geo-Seal® CORE
Product Description
Basic Use: Geo-Seal CORE is a polymer modified asphalt (PMA)
applied to nominal dry thicknesses depending on the configuration
of the Geo-Seal system vapor intrusion barrier system. Spray
applied to form a seamless barrier, Geo-Seal CORE is an integral
component to all Geo-Seal systems due to its ability to bond to
and seam high density polyethylene (HDPE), polyolefin sheets.
Geo-Seal CORE is applied with a proprietary self-contained
sprayer designed to produce a high build, monolithic, and
rapidly curing membrane.
Composition: Geo-Seal CORE is a non-hazardous, low-viscosity,
water-based, anionic asphalt emulsion modified with a blend of
synthetic polymerized rubbers and proprietary additives. Geo-Seal
CORE is highly stable during transit and proper storage, but
becomes highly reactive during the spray application to form a
rapidly cured membrane with exceptional bonding, elongation,
and hydrophobic characteristics.
Benefits
• Provides a layer of seamless protection and redundancy in
all Geo-Seal system assemblies
• Hydrophobic and resistant to methane gas
• Non-toxic, non-hazardous, non-flammable, and VOC free
• Forms a tenacious bond to HDPE sheets
• Application to damp substrates is acceptable
• Can be applied in below freezing temperatures with proper
equipment
Limitations
• Surfaces shall be free of dirt and debris
• Material should be stored above 40°F and not allowed
to freeze
• Not a traffic bearing surface, additional protection required
• Must not be applied to ponded water
• Direct foot traffic should be limited when ambient air
temperatures are greater than 100°F
Technical Data
Shelf life: 6 months. The ability to apply the product beyond
its estimated shelf life is dependent on storage conditions and
homogeneity of the product. Storing material in an enclosed
temperature controlled environment that maintains a minimum
ambient temperature of 65° Fahrenheit will likely extend the
shelf life beyond 6 months.
Properties: See physical properties table
Specification Writer: Contact EPRO before writing specifications
on this product. Geo-Seal system assemblies should be reviewed
in order to meet project specific site conditions.
Additional test information available upon request.
Installation
EPRO Authorized Applicators must be approved in writing by
EPRO prior to receiving a contract in order to qualify for a
warranty for this product and system assembly.
Surface Preparation: All surfaces shall be prepared in
accordance to manufacturer’s specifications. Surfaces shall be
uniform, free of loose materials, and surface contaminants.
Contaminant and loose debris shall be removed prior to
application by suitable methods.
Application: Please refer to manufacturer’s specifications.
Geo-Seal CORE shall be spray applied to the specified nominal
mil thickness. When properly applied, Geo-Seal CORE will set
up immediately on the surface and promptly start the curing
process. Light foot traffic is acceptable, but must be limited to
the authorized Geo-Seal applicator. The initial cure is complete
when Geo-Seal CORE is no longer ejecting moisture, 12 to 48
hours depending on ambient air conditions.

explicitly stated in the contract documents, the vapor intrusion barrier contractor is not responsible
for surface preparation.
B. Examine all substrates, areas, and conditions under which the membrane system will be installed,
applicator and inspector must be present. Do not proceed with installation until unsatisfactory
conditions have been corrected and surface prepration requirements have been met. If conditions
exist that are not addressed in this section, notify inspector and contact EPRO for additional
clarification.
C. Soil and Sand Substrates: Native soil and sand substrates shall be uniformly compacted to meet
structural and building code requirements. All surfaces shall be free from protrusions and debris
that may compromise the membrane system. Free standing water must be removed prior to
application.

Ó2020 EPRO Services, Inc. EproGSEV20.VB.v1.08.20gs 8
D. Aggregate Substrates: Aggregate substrates shall be compacted to meet structural and building
code requirements and then rolled flat to provide a uniform substrate. ¾ inch minus aggregate
with no more than one fractured face is recommended, but other aggregates substrates may be
approved by the manufacturer provided they do not create sharp angular protrusions that may
compromise the vapor intrusion system.
E. Working Slab: Mud slab, rat slab, or other concrete working slab shall have a uniform plane with a
light broom or light trowel finish.
F. Concrete Surfaces: Clean and prepare concrete surface to manufacturer’s recommendations. In
general, only apply the Geo-Seal CORE material to dry, clean and uniform concrete substrates
with a light trowel, light broom, or equivalent finish.
G. Cast-in-Place or Shotcrete Walls: Application to green concrete is acceptable provided the
substrate is prepared in accordance with manufacturers specifications and published instructions.
1. Provide clean, dust-free, and dry substrate for vapor intrusion barrier application.
2. Surfaces shall be power washed to remove grease, oil, form release agents, or any other
penetrating contaminants from the concrete.
3. Remove all fins, ridges, and other protrusions.
4. Fill honeycomb, aggregate pockets, tie holes, and other voids with hydraulic cement, or
rapid-set grout.
3.2 VAPOR INTRUSION BARRIER INSTALLATION
A. General: The underslab vapor intrusion system shall be installed under strict accordance with the
manufacturer’s guidelines and project specifications.
3.2.2 EVOH GEOCOMPOSITE SHEET MEMBRANE – GEO-SEAL EV20
A. Whenever possible roll out Geo-Seal EV20 in the same direction over the substrate with geotextile
side facing down, away from the installer. When multiple pours will occur, extend the Geo-Seal
EV20 a minimum of 2 feet past the pour joint.
B. Overlap Geo-Seal EV20 a minimum of 6 inches.
C. At the seam overlap, peel back the top layer of Geo-Seal EV20 and apply 60 mils into the
overlapping seam, making certain to apply Geo-Seal CORE to both the top of the bottom sheet
and the bottom of the top sheet. Embed the top sheet into the bottom sheet.
D. Visually verify there are no gaps/fish-mouths in seams.
3.2.3 POLYMER MODIFED ASPHALT MEMBRANE – GEO-SEAL CORE
A. Mask off adjoining surfaces where unwanted Geo-Seal CORE polymer modified asphalt
membrane may be exposed on finished surfaces or impact other construction trades.
B. Commence application of Geo-Seal CORE polymer modified asphalt when ambient air
temperatures are within manufacturer recommendations.
C. Surfaces that will receive the membrane must be clean and free from standing moisture.
D. Start installing Geo-Seal CORE in presence of approved 3rd party inspector or required city
inspector.
Ó2020 EPRO Services, Inc. EproGSEV20.VB.v1.08.20gs 9
E. Apply one application of Geo-Seal CORE membrane in accordance to manufacturer’s instructions
in order to obtain a seamless membrane with a minimum dry film thickness of 60 mils (1.5 mm).
F. Apply Geo-Seal CORE/Geo-Seal CORE Detail in and around penetrations and cavities to ensure
the formation of monolithic seal around all penetrations.
G. Apply Geo-Seal CORE/Geo-Seal CORE Detail to prepared wall terminations and vertical surfaces
to heights indicated according to manufacturer’s recommendations and details. (if applicable)
3.2.4 TERMINATION SEQUENCE
A. System Termination: The termination process is appropriate for terminating the membrane onto
exterior footings, pile caps, interior footings and grade beams. When terminating the membrane to
stem walls or vertical surfaces the same process should be used.
1. Concrete surfaces that are not a light trowel, light broom or equivalent finish, will need to
be repaired.
2. Terminations on horizontal and vertical surfaces should extend 6” onto the termination
surface. Job specific conditions may prevent a 6” termination.
3. Apply 60 mils of Geo-Seal CORE to the terminating surface and then embed the Geo-
Seal EV20 layer by pressing it firmly into the Geo-Seal CORE layer.
4. Apply 30 mils of Geo-Seal CORE over the edge of termination. For further clarification,
refer to the termination detail provided by the manufacturer.
3.2.5 SEALING OF PENETRATIONS
A. Sealing of Standard Pipe Penetrations: Prepare membrane penetrations so they are free of any
material that will inhibit a direct bond to the penetration surface: foam, insulation, protective
coatings, etc.
1. Trim Geo-Seal EV20 to within 1/8 inch of the penetration.
2. Apply Geo-Seal CORE Detail 3 inches horizontally and 3 inches vertically around the
base of the penetration.
3. Embed Geo-Seal Reinforcement Fabric reinforcement fabric 3 inches horizontally and 3
inches vertically around the base of the penetration.
4. Apply a second layer of Geo-Seal CORE Detail to reinforcement fabric until the
reinforcement fabric is fully saturated. Secure Geo-Seal Reinforcement Fabric
reinforcement fabric to penetration with a cable tie. For further clarification, refer to the
termination detail provided by manufacturer.
3.3 FIELD QUALITY CONTROL
A. Smoke Test: Conduct smoke test on all underslab areas upon installation of the Geo-Seal EV20
sheet, the sealing of all penetrations, terminations, and sheet membrane overlaps. All deficient
areas shall be noted, marked for repair, and repairs verified. Refer to manufactures smoke testing
protocol for additional guidance.
B. Field Inspection: Contact EPRO for independent certification process.
Ó2020 EPRO Services, Inc. EproGSEV20.VB.v1.08.20gs 10
C. Take care to prevent contamination and damage during application stages and curing. Machinery,
additional trades, or general construction shall NOT take place over the membrane until inspection
is complete and concrete has been placed. The membrane shall always be properly protected
when equipment is operated near the membrane.
D. Prevent damage during the placement of reinforcement steel and overburden.
E. Damage Observation: Prior to the placement of concrete a visual inspection to confirm no damage
has occurred from construction traffic or during the placement of reinforcement steel is
recommended.
3.4 REPAIRS
A. Underslab:
1. Inspect damaged area to determine which system components have been damaged.
2. If the Geo-Seal EV20 sheet has not been compromised, patch only the areas that have
been damaged by re-installing the damaged materials. The patch should extend 6 inches
beyond the damaged area in all directions.
3. If the Geo-Seal EV20 sheet has been breached but no additional system components

TO FORM AN "L" SHAPE. A MINIMUM OF 6" SECTION OF PIPING IS SET WITHIN THE BASE COURSE
LAYER WITH AN OPEN-ENDED PIPE OR PIPE PROTECTION SCREEN AT THE TERMINATION. THE PIPE
TERMINATION IS ENCASED WITHIN THE BASE COURSE LAYER. THE HORIZONTAL PIPING WAS
SLOPED A MINIMUM OF 1/8 UNIT VERTICAL BY 12 UNITS HORIZONTAL (1% SLOPE) TO GRAVITY
DRAIN TOWARDS THE PIPE TERMINATION AND PREVENT MOISTURE FROM COLLECTING AT THE
90-DEGREE ELBOW. A 4-INCH DIAMETER ADJUSTABLE FLOOR CLEAN-OUT (ZURN INDUSTRIES
MODEL #CO2450-PV4, OR EQUIVALENT) WAS INSTALLED AND SET FLUSH WITH THE FINISHEDCONCRETE SURFACE. MONITORING POINT INTAKE IS A MINIMUM 5-FT FROM EXTERIOR FOOTING.
7.THIS VIMS PLAN WAS INTENDED TO BE USED FOR DIRECTION OF VIMS COMPONENT INSTALLATION
ONLY AND WAS NOT INTENDED TO GUIDE CONSTRUCTION OF STRUCTURAL COMPONENTS NOT
RELATED TO THE VIMS. CONSTRUCTION CONTRACTOR VERIFIED CONSISTENCY OF VIMS DETAILS
WITH APPLICABLE STRUCTURAL, ARCHITECTURAL, MECHANICAL, AND PLUMBING PLANS ANDRESOLVED ANY INCONSISTENCIES PRIOR TO VIMS INSTALLATION.
8.INSPECTIONS: INSPECTIONS OF EACH COMPONENT OF THE VIMS WAS CONDUCTED BY THE
ENGINEER, OR ENGINEER'S DESIGNEE, TO CONFIRM VIMS COMPONENTS WERE INSTALLED PER
THE APPROVED DESIGN. THE REQUIRED INSPECTION COMPONENTS INCLUDED: (1) INSPECTION
OF SUB-SLAB PIPING LAYOUT, (2) GRAVEL PLACEMENT, AND (3) MONITORING POINT PLACEMENTPRIOR TO INSTALLING VAPOR BARRIER; (4) INSPECTION OF VAPOR BARRIER PRIOR TO POURING
CONCRETE; (5) INSPECTION OF ABOVE-GRADE PIPING LAYOUT; AND (6) INSPECTION OF TURBINEFANS AND RISER DUCT PIPE CONNECTIONS. INSPECTIONS WERE COMBINED WHEN POSSIBLE
DEPENDING ON THE CONSTRUCTION SEQUENCE/SCHEDULE. THE CONSTRUCTIONCONTRACTOR(S) COORDINATED WITH THE ENGINEER TO PERFORM THE REQUIRED INSPECTIONS.
DEQ WAS CONTACTED 48-HOURS PRIOR TO THE INSPECTION BEING CONDUCTED. FIELD NOTES,PHOTOGRAPHS, AND ANY ADDITIONAL INSPECTION DOCUMENTATION ARE INCLUDED IN THE FINAL
DELIVERABLE TO DEQ.
9.CONSTRUCTION CONTRACTORS AND SUB-CONTRACTORS USED "LOW OR NO VOC" PRODUCTSAND MATERIALS, WHEN POSSIBLE. THE CONSTRUCTION CONTRACTOR AND SUB-CONTRACTORS
PROVIDED SAFETY DATA SHEETS (SDS) TO THE ENGINEER FOR PRODUCTS AND MATERIALS USEDDURING CONSTRUCTION. SDS SHEETS ARE INCLUDED IN FINAL REPORTING TO DEQ.
10.CONSTRUCTION CONTRACTORS AND SUB-CONTRACTORS AVOIDED THE USE OF TEMPORARY
FORM BOARDS OR HOLLOW PIPING (TYPICALLY USED TO SUPPORT UTILITIES PRIOR TO SLAB
POURS) THAT PENETRATE THE VAPOR BARRIER WHERE POSSIBLE. IF TEMPORARY FORM BOARDS
WERE USED, THE SIZE AND NUMBER OF PENETRATIONS THROUGH THE VAPOR BARRIER WERELIMITED AND SMALL DIAMETER STAKES (I.E. METAL STAKES) WERE USED. IN ALL CASES, AS FORM
BOARDS ARE REMOVED, THE CONTRACTOR OR SUB-CONTRACTORS SEALED ALL PENETRATIONSIN ACCORDANCE WITH VAPOR BARRIER MANUFACTURER INSTALLATION INSTRUCTIONS.

VIMS SPECIFICATIONS
1.VIMS VAPOR BARRIER IS GEO-SEAL EV20S MANUFACTURED BY EPRO SERVICES, INC.
THE VAPOR BARRIER WAS INSTALLED AS SPECIFIED HEREIN AND PER MANUFACTURER INSTALLATION
INSTRUCTIONS TO CREATE A CONTINUOUS BARRIER BELOW GROUND FLOOR SLABS AND
ATTACHED/SEALED TO CONCRETE SURFACES OF FOOTINGS AND EXTERIOR/EXISTING WALLS. A MINIMUM
5-INCH THICK BASE COURSE CONSISTING OF CLEAN #57 STONE WAS INSTALLED BENEATH THE VIMS
VAPOR BARRIER.
2.HORIZONTAL COLLECTION PIPE CONSISTS OF 4-INCH SCH 40 PVC (OR OTHERWISE NOTED IN THE
DRAWINGS). SUB-SLAB SLOTTED VAPOR COLLECTION PIPE IS THREADED FLUSH JOINT OR SLIP JOINT
4-INCH SCH 40 PVC PIPE WITH 0.020-INCH SLOT WIDTH AND 1/8-INCH SLOT SPACING. VIMS BELOW AND
ABOVE GRADE SOLID PIPING IS NOT TRAPPED AND IS SLOPED A MINIMUM OF 1/8 UNIT VERTICAL IN 12
UNITS HORIZONTAL (1% SLOPE) TO GRAVITY DRAIN. SOLID SECTIONS OF HORIZONTAL COLLECTION PIPE
WAS SUPPORTED TO PREVENT PIPE SAG OR LOW POINT AND MAINTAIN 1% SLOPE TOWARD SLOTTED
SECTIONS TO DRAIN CONDENSATION. TRACER WIRE WAS PLACED ALONG HORIZONTAL PIPE BELOW
VAPOR BARRIER TO LOCATE PIPE DURING FUTURE BUILDING MODIFICATIONS.
3.4-INCH CAST IRON RISER DUCT PIPING WAS INSTALLED TO CONNECT EACH SLAB PENETRATION
LOCATION TO A ROOFTOP EXHAUST DISCHARGE POINT WITH TURBINE FAN (SEE SPECIFICATION #4).
ABOVE-SLAB RISER DUCT PIPE RUNS BETWEEN THE SLAB PENETRATION AND THE ROOFTOP EXHAUSTDISCHARGE WAS INSTALLED PER APPLICABLE BUILDING CODE AND AS SPECIFIED IN THE CONSTRUCTION
DOCUMENTS AND DRAWINGS.
4.RISER DUCT PIPING EXTENDS IN A VERTICAL ORIENTATION THROUGH THE BUILDING ROOF AND
TERMINATES A MINIMUM OF 2 FT ABOVE ANY WALLS, PARAPETS, ETC. IN THE VICINITY OF THE RISER/FAN.
AN EMPIRE MODEL TV04SS TURBINE VENTILATOR FAN WAS INSTALLED ON THE EXHAUST DISCHARGE
END OF EACH MINIMUM OF 10 FT FROM ANY OPERABLE OPENING OR AIR INTAKE INTO THE BUILDING.
NOTE THAT DISCHARGE LOCATIONS ON THE ROOFTOP DEPICTED IN THE VAPOR MITIGATION PLAN MAY
HAVE BEEN REPOSITIONED AS LONG AS THE NEW POSITION MET THE REQUIREMENTS PRESENTED
ABOVE. A 4-INCH COUPLING WAS INSTALLED AT THE DISCHARGE END OF THE 4-INCH RISER DUCT PIPE
AND THE FAN IS SECURED TO THE PVC RISER IN A VERTICAL ORIENTATION. AN ELECTRICAL JUNCTION
BOX (120V, 60HZ AC REQUIRED) WAS INSTALLED NEAR THE FAN LOCATION ON THE ROOFTOP FOR
CONVERSION TO ELECTRIC FANS, IF REQUIRED. ALL WIRING AND ELECTRICAL WAS INSTALLED PER
APPLICABLE BUILDING AND ELECTRICAL CODES.
5.ABOVE-SLAB ACCESSIBLE RISER DUCT PIPING IS PERMANENTLY IDENTIFIED BY MEANS OF A TAG OR
STENCIL AT A MINIMUM OF ONCE EVERY 10-LINEAR FT WITH "VAPOR SYSTEM - CONTACT OWNER.”
LABELS ARE ALSO FIXED TO THE TURBINE FANS IN AN ACCESSIBLE LOCATION ON THE ROOFTOP.
6.MONITORING POINTS CONSIST OF 2-INCH DIAMETER SCH 40 PVC PIPE WITH A 90-DEGREE ELBOW TO
FORM AN "L" SHAPE. A MINIMUM OF 6" SECTION OF PIPING IS SET WITHIN THE BASE COURSE LAYER WITH
AN OPEN-ENDED PIPE OR PIPE PROTECTION SCREEN AT THE TERMINATION. THE PIPE TERMINATION IS
ENCASED WITHIN THE BASE COURSE LAYER. THE HORIZONTAL PIPING WAS SLOPED A MINIMUM OF 1/8
UNIT VERTICAL BY 12 UNITS HORIZONTAL (1% SLOPE) TO GRAVITY DRAIN TOWARDS THE PIPE
TERMINATION AND PREVENT MOISTURE FROM COLLECTING AT THE 90-DEGREE ELBOW. A 4-INCH
DIAMETER ADJUSTABLE FLOOR CLEAN-OUT (ZURN INDUSTRIES MODEL #CO2450-PV4, OR EQUIVALENT)
WAS INSTALLED AND SET FLUSH WITH THE FINISHED CONCRETE SURFACE. MONITORING POINT INTAKE ISA MINIMUM 5-FT FROM EXTERIOR FOOTING.
7.THIS VIMS PLAN WAS INTENDED TO BE USED FOR DIRECTION OF VIMS COMPONENT INSTALLATION ONLY
AND WAS NOT INTENDED TO GUIDE CONSTRUCTION OF STRUCTURAL COMPONENTS NOT RELATED TO
THE VIMS. CONSTRUCTION CONTRACTOR VERIFIED CONSISTENCY OF VIMS DETAILS WITH APPLICABLE
STRUCTURAL, ARCHITECTURAL, MECHANICAL, AND PLUMBING PLANS AND RESOLVED ANYINCONSISTENCIES PRIOR TO VIMS INSTALLATION.
8.INSPECTIONS: INSPECTIONS OF EACH COMPONENT OF THE VIMS WAS CONDUCTED BY THE ENGINEER,
OR ENGINEER'S DESIGNEE, TO CONFIRM VIMS COMPONENTS WERE INSTALLED PER THE APPROVED
DESIGN. THE REQUIRED INSPECTION COMPONENTS INCLUDED: (1) INSPECTION OF SUB-SLAB PIPING
LAYOUT, (2) GRAVEL PLACEMENT, AND (3) MONITORING POINT PLACEMENT PRIOR TO INSTALLING VAPOR
BARRIER; (4) INSPECTION OF VAPOR BARRIER PRIOR TO POURING CONCRETE; (5) INSPECTION OF
ABOVE-GRADE PIPING LAYOUT; AND (6) INSPECTION OF TURBINE FANS AND RISER DUCT PIPECONNECTIONS. INSPECTIONS WERE COMBINED WHEN POSSIBLE DEPENDING ON THE CONSTRUCTION
SEQUENCE/SCHEDULE. THE CONSTRUCTION CONTRACTOR(S) COORDINATED WITH THE ENGINEER TOPERFORM THE REQUIRED INSPECTIONS. DEQ WAS CONTACTED 48-HOURS PRIOR TO THE INSPECTION
BEING CONDUCTED. FIELD NOTES, PHOTOGRAPHS, AND ANY ADDITIONAL INSPECTION DOCUMENTATION
ARE INCLUDED IN THE FINAL DELIVERABLE TO DEQ.
9.CONSTRUCTION CONTRACTORS AND SUB-CONTRACTORS USED "LOW OR NO VOC" PRODUCTS AND
MATERIALS, WHEN POSSIBLE. THE CONSTRUCTION CONTRACTOR AND SUB-CONTRACTORS PROVIDEDSAFETY DATA SHEETS (SDS) TO THE ENGINEER FOR PRODUCTS AND MATERIALS USED DURING
CONSTRUCTION. SDS SHEETS ARE INCLUDED IN FINAL REPORTING TO DEQ.
10.CONSTRUCTION CONTRACTORS AND SUB-CONTRACTORS AVOIDED THE USE OF TEMPORARY FORM
BOARDS OR HOLLOW PIPING (TYPICALLY USED TO SUPPORT UTILITIES PRIOR TO SLAB POURS) THAT
PENETRATE THE VAPOR BARRIER WHERE POSSIBLE. IF TEMPORARY FORM BOARDS WERE USED, THESIZE AND NUMBER OF PENETRATIONS THROUGH THE VAPOR BARRIER WERE LIMITED AND SMALL
DIAMETER STAKES (I.E. METAL STAKES) WERE USED. IN ALL CASES, AS FORM BOARDS ARE REMOVED,THE CONTRACTOR OR SUB-CONTRACTORS SEALED ALL PENETRATIONS IN ACCORDANCE WITH VAPOR
BARRIER MANUFACTURER INSTALLATION INSTRUCTIONS.S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Figures\VIMP-Details_As-Built.dwg, VM-2, 7/29/2022 12:26:59 PM, SVincent
