Vapor Intrusion Mitigation Plan – Revision 2 North Davidson II Brownfields Property 2315 N. Davidson Street & 421 E. 26th Street Charlotte, North Carolina Brownfields Project No. 24003-20-060
H&H Job No. PAM-003
1.0 Introduction

On behalf of Mill District Partners LLC, Hart & Hickman, PC (H&H) has prepared this Vapor
Intrusion Mitigation Plan (VIMP) for the redevelopment of the North Davidson II Brownfields
property [North Carolina Department of Environmental Quality (DEQ) Brownfields Project No.
24003-20-060] located at 2315 N. Davidson Street and 421 E. 26th Street in Charlotte,
Mecklenburg County, North Carolina (Site or subject Site). A Site location map is provided as
Figure 1.

The Site consists of two contiguous parcels of land (Parcel Identification Numbers 08305204 and
08305206) that total approximately 3.8 acres. The southeastern parcel (2315 N. Davidson Street)
is developed with an approximate 28,000-square foot (sq ft) vacant commercial building, and the
northwestern parcel (421 E. 26th Street) is developed with an approximate 15,500-sq ft vacant
commercial building. An inactive rail corridor that is owned by the City of Charlotte separates the
two Site parcels. A Site Layout map is presented as Figure 2.

The existing building on the southeastern parcel was constructed in 1950 and was utilized as an
electrical appliance warehouse, a knit goods manufacturing facility, and a cork and insulation
warehouse in the 1950s. Subsequently, the building appears to have been occupied by various
warehouse facilities until the 1990s, when a previous owner renovated the building for use as an
event venue. The northern portion of the building was also utilized as a brewery in the 2010s.

The northwestern parcel was developed with a concrete plant and an automotive repair shop in the
early to mid-1950s. The concrete plant operated until the late 1950s, and the automotive repair
shop operated until at least the late 1960s. Additional buildings, including the existing warehouse,
were constructed on the northwestern parcel in the 1950s and 1960s. The buildings appear to have

M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
been used as part of lumber company, automotive scrapyard, automotive repair, automotive body
shop, and warehouse operations. Between the 1970s and the early 2000s, several structures on the
northwestern parcel were razed.

In August 2019, H&H completed sub-slab vapor sampling activities at the Site to evaluate the
potential for vapor intrusion into the buildings. Sub-slab vapor data were compared to the February
2018 DEQ Soil Gas Screening Level (SGSLs). A summary of the results of the sub-slab vapor
sampling activities is provided below, and excerpts from the previous assessment reports are
included in Attachment A.

• Trichloroethene (TCE; 91,000 μg/m3) was detected in sub-slab vapor sample SS-1 (west-
central portion of 2315 N. Davidson Street building) above DEQ non-residential SGSL of
180 μg/m3. Tetrachloroethene (PCE; 860 μg/m3) and chloroform (260 µg/m3) were also
detected in sample SS-1 above the residential SGSL for PCE of 280 μg/m3 and the non-
residential SGSL for chloroform of 53 μg/m3.
• TCE (27 μg/m3) was detected in sub-slab vapor sample SS-2 (south-central portion of 2315
N. Davidson Street building) above the residential SGSL of 14 μg/m3.
• No volatile organic compounds (VOCs) were detected above the residential or non-
residential SGSLs in sub-slab vapor samples collected in the building at 421 E. 26th Street.

To further evaluate vapor intrusion and potential occupant exposure to chloroform, PCE, and TCE,
H&H conducted indoor air sampling activities in the building at 2315 N. Davidson Street in
November 2019. A summary of the results of the indoor air sampling is provided below.

• H&H collected four indoor air samples (IAS-1 through IAS-4) in the Site building at 2315
N. Davidson Street. Based on August 2019 sub-slab vapor sampling results, the samples
were analyzed for chloroform, PCE, and TCE.
• Laboratory analytical results indicated the presence of chloroform (up to 0.2 μg/m3) and/or
PCE (up to 0.34 μg/m3) in indoor air samples IAS-1 through IAS-4. The detected
concentrations exceed the residential Indoor Air Screening Levels (IASLs) of 0.12 μg/m3 and
3
M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
8.3 μg/m3 for chloroform and PCE, respectively. TCE (0.14 μg/m3) was detected in sample
IAS-1 at a concentration below the residential IASL of 0.42 μg/m3.

On August 12, 2020, H&H conducted sub-slab vapor assessment activities at the Site to confirm
the August 2019 data. Four sub-slab vapor samples (SS-7 through SS-10) were collected in the
building at 2315 N. Davidson Street, and three sub-slab vapor samples (SS-11 through SS-13)
were collected from the building at 421 E. 26th Street.

Sub-Slab Vapor
• Chloroform, naphthalene, and PCE were detected in one or more samples at concentrations
above the February 2018 residential SGSLs .
• TCE was detected at concentrations above the February 2018 non-residential SGSLs in
four sub-slab vapor samples and a duplicate sample collected in the building at 2315 N.
Davidson Street.
• No VOCs were detected in sub-slab vapor samples collected in the building at 421 E. 26th
Street at concentrations above the February 2018 residential or non-residential SGSLs.
• The results of the risk calculations using sub-slab vapor data for the building at 2315 N.
Davidson Street indicate that calculated carcinogenic and non-carcinogenic risks are above
acceptable risk levels for the residential and non-residential worker exposure scenarios.
The results of the risk calculations using sub-slab vapor data for the building at 421 E. 26th
Street indicate that the calculated carcinogenic and non-carcinogenic risks are below
acceptable risk levels for residential and non-residential worker exposure scenarios.
• Based on review of DEQ records, the inferred direction of groundwater flow in the vicinity
of the Site, the results of prior on-Site and off-Site groundwater sampling, and the location
of on-Site sub-slab vapor impacts, the sub-slab vapor impacts at the Site appear to be
related to groundwater contamination that is sourced from the upgradient former Gibbs
Electroplating and/or Applied Research Group facilities located south of the Site.

The Prospective Developer (PD) plans to redevelop the existing buildings for restaurant, office,
and other commercial uses including retail, warehousing, entertainment, and brewery or food
production facility. No additional buildings are proposed to be developed on the Site at this time.

The draft Notice of Brownfields Property (NBP) is currently under review by DEQ. It is
anticipated the NBP will include the following land use restriction related to vapor intrusion:

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 referenced
below, may be occupied until DEQ determines in writing that: i. The building is or would be protective 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 intrusion mitigation measures are designed, installed, inspected, and
implemented in accordance with the then current DEQ Brownfields Vapor
Intrusion Mitigation Design Submittal, Minimum Design Requirements Checklist, subject to DEQ’s prior written satisfaction, and to the written satisfaction of a professional engineer licensed in North Carolina, as evidenced by said engineer’s professional seal on a report certifying that the vapor intrusion mitigation system
is fully protective of public health. Such a report shall include photographs and a
description of the installation and performance of said mitigation measures to DEQ’s written satisfaction. All design specifications for vapor intrusion mitigation measures shall be submitted to DEQ in advance of installation and/or implementation of said measures.

Based on the prior sub-slab soil vapor sampling results, vapor intrusion mitigation controls are
warranted for the 2315 N. Davidson Building. As a precaution, even though VOCs were not
detected in sub-slab vapor samples above residential or non-residential SGSLs at the 421 E. 26th
building and risk calculations indicated acceptable results, vapor intrusion mitigation controls will
also be implemented for this building. The vapor intrusion mitigation systems (VIMS) herein are
designed to mitigate the potential for sub-surface vapor intrusion and are designed to protect public
health in regards to vapor intrusion risks from known Brownfields Property contaminants. The
proposed VIMS are described in the following sections.

M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
2.0 Design Basis

The VIMS Plan is described in the following sections and was designed in accordance with the
DEQ Division of Waste Management (DWM) Vapor Intrusion Guidance (VI Guidance) dated
March 2018 and the DEQ Brownfields Program Preliminary Vapor Intrusion Mitigation System
Design Submittal New Construction Minimum Requirements Checklist included as Appendix H of
the VI Guidance document.

H&H has prepared this VIMP to address potential vapor intrusion risks to future occupants upon
completion of redevelopment activities at the Site. The VIMS Plan includes VIMS designs for
both the existing building located at 2315 N. Davidson Street (2315 N. Davidson Building) and
the existing building located at 421 E. 26th Street (421 E. 26th Building).

The proposed development at the 2315 N. Davidson Building includes retrofitting the building as
a food hall with commercial restaurants, a micro-brewery, and seating space on the western portion
of the building, and proposed office space on the southeastern portion of the building. The food
hall will be known as the UDM Food Hall. The office space will be separated from the rest of the
building with a tenant separation wall that will be installed without doorways or connection of
HVAC equipment between the spaces. Note, as of the date of the VIMP, a tenant has not leased
the proposed office space. However, as a precaution because a sub-grade footer is not present at
the proposed tenant separation wall, this design also includes a VIMS within the proposed office
space. The VIMS in the 2315 N. Davidson Building will operate as an active sub-slab
depressurization system with electric fans to extract sub-slab vapors and discharge them above the
building roofline.

The proposed development at the 421 E. 26th Building includes retrofitting the building as a
commercial restaurant and entertainment space that will be occupied by Seoul Food Company. A
small building extension on the eastern portion of the existing slab will be constructed to serve as
a kitchen extension and storage space, including the walk-in refrigerator/freezer. In addition, the
proposed development includes an outdoor (open air) bar located on the eastern portion of the
building. The VIMS in the 421 E. 26th Building will operate as a passive sub-slab depressurization

system with wind-driven turbines to extract sub-slab vapors and discharge them above the building
roofline.

The VIMS design for the 2315 N. Davidson Building is included as Sheets VM-1, VM-1A,
VM-2, and VM-3 provided in Attachment B and will be used to guide installation of the system.
The VIMS design for the 421 E. 26th Building is included as Sheets VM-4, VM-5, and VM-6
provided in Attachment C and will be used to guide installation of the system. A summary of the
design basis and components for each VIMS for each building is included in the following sections.

2.1 Pilot Testing Activities

Pilot test activities were conducted in both buildings on the Site in order to assess the sub-slab
conditions to assist with the design of the VIMSs. A brief description of the pilot test activities is
described below. The results of the pilot tests were used to aid in the design of the VIMSs.

Pilot Test Methodology
The pilot influence testing for both buildings included installation and testing of suction points in
select locations in each zone of the buildings. The pilot test suction points were installed by coring
a 4-inch (in) diameter boring through the concrete floor slab at each location and removing
approximately 0.5 sq ft of sub-slab soil from the boring to create a void space. A 4-in diameter
PVC vapor intake pipe was sealed with a rubber fitting to the opening of the boring at the concrete
floor interface. Observation points were constructed by drilling a 5/8-in diameter borings through
the floor slab and were installed at various intervals (typically 5 to 10 ft) to approximately 20 ft to
40 ft from each suction point.

Following installation of the suction and observation points, pilot testing was performed by
connecting extraction fans with an in-line manifold allowing variable vacuum pressure application
to the suction point. The pilot test fans included electric radon-style fans (e.g., RadonAway
RP-265 and Festa AMG Eagle Extreme) and a 6.5 hp wet/dry shop vacuum (shop vac). Variable
vacuum pressures were applied ranging from approximately 2 to 40 inches of water column (in-
WC) at each suction point depending on the observed results during the test. H&H utilized a
7
M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
digital manometer that could read down to 0.001 in-WC to measure differential pressure between
the sub-slab and indoor air at the observation points and vacuum fans. In addition, air velocity at
the fan was measured using an anemometer, and air flow rates in cubic feet per minute (CFM)
were calculated based upon the measurements. While any measurable vacuum below the slab
indicates that vacuum influence is present in that area, vacuum measurements of at least 0.016 in-
WC [4 pascals (Pa)] are desirable because this is the minimum vacuum deemed acceptable by
DEQ to demonstrate adequate sub-slab depressurization is occurring. The testing was conducted
using equipment and methods consistent with protocols on DEQ DWM projects and in general
accordance with Interstate Technology & Regulatory Council guidance.

After the pilot tests were completed, the removed soils were returned to each location and the core
drill and hammer drills holes were repaired with at least 4-in of concrete patch and/or urethane
sealant set flush with the surrounding concrete surface.

2315 N. Davidson Building
From March 31 to April 2, 2020, H&H conducted sub-slab influence pilot testing at seven locations
in the 2315 N. Davidson Building to evaluate sub-slab vapor communication beneath the existing
slab to assist with VIMS design. The locations of the suction points (T-1 through T-7) are depicted
on Figure D-1, and the results are summarized in Table D-1 in Attachment D.

Results of sub-slab influence pilot testing indicate that sub-slab conditions are favorable for
installation of a depressurization system with moderate to high suction fans at the 2315 N.
Davidson Building. Generally, vacuum influence varied in different sections of the building. Soil
was observed directly below the concrete slab in each section of the building. The northern,
western, and southwestern portions of the building (locations T-1, T-2, T-4, and T-6) exhibited
moderate vacuum sub-slab influence, the eastern portion of the building (location T-3) exhibited
poor vacuum influence, and the southern portion of the building (locations T-5 and T-7) exhibited
good vacuum influence. The soils in the southern portion of the building generally contained more
sand than the other portions which likely contributed to the greater influence. During the pilot test,
no large cracks, holes, or damage to the existing concrete was observed. In addition, shallow or
perched water below the slab was not observed.

M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
421 E. 26th Street Building
On September 3 and 4, 2020 H&H conducted sub-slab influence pilot testing at three locations in
the 421 E. 26th Building to evaluate sub-slab vapor communication beneath the existing slab to
assist with VIMS design. The locations of the suction points (TP-1, TP-2, and TP-3) are depicted
on Figure E-1 and results are summarized in Table E-1 in Attachment E.

Results of sub-slab influence pilot testing indicate that sub-slab conditions are favorable for
installation of a low vacuum sub-slab depressurization system or a passive system. Soil was
observed directly below the concrete slab at test locations TP-1 and TP-2, but generally good
vacuum influence was observed at these locations. At location TP-3, a sub-slab void was observed
located below the extraction point. During the testing at TP-3, when vacuum was applied to the
sub-slab void, notable vacuum influence was measured in almost every point across the entire
building slab. Therefore, this indicates the sub-slab void has connection throughout the building.
Further investigation conducted by the PD indicated the sub-slab void is approximately 4 ft to 6 ft
deep, 6 ft wide, and 50 ft long. The void has cinder block walls and seems to be a former structural
component. The PD plans to fill the void with high-permeability gravel such as 57 stone or pea
gravel during building retrofit activities. Therefore, this void is expected to have similar air
transmissivity after retro-fit activities are completed as measured during the pilot test activities.
Note, the VIMS design includes a proposed extraction point (F-3) located at this sub-slab void
(Section 2.2).

During the pilot test, some cracks and slab damage were observed in the northern portion of the
building, but these slab conditions do not appear to have significantly affected the pilot test results.
In addition, shallow or perched water below the slab was not observed.

2.2 VIMS Design Components

The main components of the VIMS are detailed in the design sheets and are briefly summarized
below. Product specification sheets are included in Attachment F.

M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
2.2.1 2315 N. Davidson Building

The VIMS design for the 2315 N. Davidson Building is included as Sheets VM-1, VM-1A,
VM-2, and VM-3 provided in Attachment B and will be used to guide installation of the system.
The area for the proposed UDM Food Hall is approximately 19,600 sq ft, and the area for the
proposed office upfit is approximately 8,400 sq ft. The entire building contains a concrete slab
that is approximately 4 in to 6 in thick and the building contains one story.

Suction Point and Suction Trenches
Based upon the pilot testing results (Section 2.1) and the proposed building layout, the VIMS
includes a combination of suction points and suction trenches to achieve sub-slab depressurization.
The general configuration of the suction points and suction trenches are shown on the design sheet
VM-2 in Attachment B.

In general, at each suction point, a cavity (approximately 0.75 to 1 cubic ft) will be excavated
beneath the bottom of the slab. The suction point will consist of 3-in Sch 40 PVC pipe with a vent
cap end installed within the cavity. In addition, several 5/8-in diameter holes may be drilled into
the sides of the pipe that is set within the gravel layer to further promote air flow from the sub-slab
annular space. The suction trenches generally include an approximate 12-in wide by 12-in deep
trench installed below the existing concrete. Within the suction trench, 3-in Sch 40 slotted or
perforated PVC pipe will be installed and surrounded with clean gravel. The vent piping within
the suction trenches will be connected to the solid riser pipes. Note, in some areas, including
locations F-4 and F-5, other sub-surface utility trenches are proposed to be installed that run
perpendicular to the proposed suction trenches. The other utility trenches are proposed to be filled
with crushed gravel. Therefore, in order to prevent direct air short circuiting from the suction
trench to the other utilities, a section of solid pipe will be installed inside of the suction trench and
connected to an individual suction point (Detail 4 on Sheet VM-2) at these locations. Furthermore,
a section of compacted soil will be placed near the other utilities to provide a low-permeability
layer between the suction point and the other utility trenches.

10
M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
The suction point cavity and areas surrounding slotted sections of suction trench piping will be
backfilled with washed (clean) #57 stone or washed pea gravel (or similar high permeability stone
approved by the engineer). A section of 3-in diameter solid Sch. 40 PVC riser piping then be
connected to piping with the suction point or suction trench and positioned inside of a stud wall or
adjacent to an existing wall as depicted in the design sheets. The riser piping will extend to roof
and connected to the electric fan. Note, the discharge locations are specified to be a minimum of
15 ft from air intakes and thus the location of the discharge point for some locations will be off-
set from the risers to account for the other building mechanical equipment. The piping off-sets
will be installed below the building roofline using 3-in Sch 40 PVC pipe. The proposed locations
of the off-set locations are depicted on Sheet VM-1A. Piping will be sloped (minimum 1%) and/or
configured to allow drainage of condensate into the sub-slab material. Each suction point, suction
trench, and the associated piping will be inspected or documented to the approval of the engineer
(or agent of), prior to repairing the concrete surfaces.

The concrete will be repaired per the construction plans with a moisture barrier installed between
the gravel layer and the new concrete. Note, concrete joints (e.g., cold joints and expansion joints),
and penetrations will be sealed with a urethane caulk or similar air-tight sealant to prevent air short
circuiting.

Area with New Concrete
A small section of slab (approximately 450 sq ft) is proposed to be removed and replaced in the
area of the former brewery in the western portion of the building during upfit activities due to
proposed equipment to be installed in this area. Therefore, in this area approximately 4-in of clean
#57 stone gravel, or similar high permeability stone, and a minimum 10-mil moisture barrier will
be installed prior to installation of the new concrete slab. The moisture barrier will be placed to
protect the new concrete and not to serve as a vapor barrier because the active fans are designed
to provide adequate sub-slab depressurization across this area. Furthermore, in order to enhance
the sub-slab depressurization in this area, slotted or perforated 3-in diameter Sch 40 PVC vent pipe
will be installed within the gravel layer and connected to riser F-6 and the associated suction trench
in this area.

Electric Fans
The proposed electric fans for each riser (F-1 through F-11) include PressureTech PT-16 Radon
Fans (PT-16) that are high vacuum suction fans with a maximum vacuum of 17.4-in WC and
maximum air flow of approximately 67 CFM. Specification sheets for the PT-16 fans are included
in Attachment F.

Monitoring Points
The proposed monitoring points are to be constructed with 1-in slotted PVC pipe installed to
approximately 12-in deep with coarse sand (Northern Filter Media 1/8 x #12 Well Pack [#2 Well
Pack], or similar coarse sand) surrounding the slotted sections. The monitoring points will be
completed with a floor clean-out cover set flush with the existing concrete floor. The monitoring
point locations were chosen to provide representative coverage across the building slab and in
locations that will be accessible for future vacuum monitoring events.

In addition, one clean-out will be installed on each pipe within a suction trench to provide access
for future maintenance, if warranted. The clean-out will be completed with a floor clean-out cover
set flush with the existing concrete floor.

Vacuum Alarm System
A vacuum alarm system will be installed to alert the building owners if an electric fan stops
operating or if vacuum levels drop below 1.0-in WC in the riser (or a vacuum level deemed
appropriate based upon pre-occupancy system efficacy testing and approval of the design
engineer). The proposed vacuum alarm system includes a Dwyer Instruments 616KD-07
Differential Pressure Sensor/Transmitter installed at each riser to monitor vacuum levels within
the riser. The differential pressure sensors will be connected to a Sensaphone Sentinel monitor
that will be programmed to send out localized and electronic alarm notifications in the event the
pre-described vacuum is not achieved. The Sentinel is designed to monitor up to 12 alarms;
therefore, one unit installed in a centralized location should be adequate to monitor each of the
proposed 11 risers and fans. The Sentinel will either be connected to the building internet signal
or connected to a separate cellular signal as will be determined by the building owner during
construction. Note, an equivalent vacuum monitoring and alarm system may be installed per

approval of the VIMS design engineer. As an extra precaution, a sign by the alarm that reads “If
Alarm Sounds, Contact Property Management”, or similar language, will be posted to alert the
building tenants. The specification sheets for the Dwyer differential pressure sensor and
Sensaphone products are included in Attachment F.

2.2.2 421 E. 26th Street Building

The VIMS design for the 421 E. 26th Building is included as Sheets VM-4, VM-5, and VM-6
provided in Attachment C and will be used to guide installation of the system. The area of the
existing slab in this building is approximately 15,500 sq ft, and the proposed building extension
on the eastern side is approximately 1,300 sq ft. The entire existing building contains a concrete
slab that is approximately 4 in thick and the building contains one story. The new building sections
will also contain an approximate 4-in thick concrete slab.

Suction Point and Suction Trenches
Based upon the pilot testing results (Section 2.1) and the proposed building layout, the VIMS
includes a combination of suction points and one suction trench to provide sub-slab
depressurization across the existing and proposed building slab. Details showing the general
configuration of the suction points and suction trench are shown on the design sheet VM-5 in
Attachment C.

In general, the suction points will be constructed identically to the suction points at the 2315 N.
Davidson Building (refer to description in Section 2.2.1). Note, riser location F-3 will include a
suction point that is installed within the sub-slab void (Section 2.1) to provide enhanced sub-slab
depressurization across a large portion of the building. In this location, the intake screen of the
suction point will be installed within the backfilled gravel within the sub-slab void.

Areas with New Concrete
A small section of concrete slab (approximately 950 sq ft) is proposed to be removed and replaced
in the area of the northern portion of the building due to cracks and damage in the concrete in this
area. In addition, the building retrofit activities include an approximate 1,300 sq ft extension on
13
M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
the eastern portion of the building for an expanded kitchen and storage area. Therefore, in these
areas, approximately 4-in of clean #57 stone gravel or similar high-permeability stone and a
minimum 15-mil vapor barrier will be installed prior to installation of the new concrete slab. The
sub-slab vapor conveyance piping network is designed to prevent accumulation of contaminant
vapors below the concrete slab, but vapor barrier will also be installed in these areas as a secondary
measure to further prevent vapor intrusion. Based on the available data for this building and the
vapor conveyance piping network, the proposed vapor barriers described below are compatible
with the expected building conditions when installed in accordance with this VIMS design.

The specified vapor barrier will be the Raven Industries VaporBlock 15 (VBP-15). The vapor
barrier will be sealed per manufacturer instructions across the area of new concrete. To summarize
the vapor barrier installation instructions, the vapor barrier will be installed by the construction
contractor to cover the base course layer below the slab area of the proposed slabs. VaporSeal™
and 2-sided butyl seal tape will be used to attach/seal the vapor barrier to concrete surfaces. Seams
within the building footprint will have a minimum 6-in overlap and will be sealed with
VaporSeal™ tape. Small puncture holes will be sealed with VaporSeal™ tape and/or Pour-N-
Seal™. Larger holes, tears, or other damage will be repaired using a patch of vapor barrier that
overlaps the damaged area and then will 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 is deemed
“ineffective” by the design engineer, Pour-N-Seal™ will be poured into a form to patch the
penetration with a vapor tight seal.

Please note that an equivalent vapor barrier approved by the design engineer which meets the
criteria specified on Sheet VM-6 of the VIMS Plan may also be used by the installation contractor,
such as the Stego Industries 15-mil Stego-Wrap. If an alternate equivalent vapor barrier is selected,
DEQ will be notified of the alternate vapor barrier request.

In order to enhance the sub-slab depressurization in this area, slotted or perforated 3-in diameter
Sch 40 PVC vent pipe will also be installed within the gravel layer and connected to the associated
risers in each area as shown on the design sheets.

Passive Wind-Driven Fans
The Plan includes Empire Model TV04SS (stainless steel) wind-driven turbine fans (or approved
alternative) installed on the discharge end of the riser duct piping on the roof. Discharge locations
must be a minimum of 2 ft above the roofline and 10 ft from operable opening or air intake into
the building. Note that fan locations on the rooftop depicted in the VIMS design may be
repositioned within the requirements specified above and pending engineer approval. Product
specifications for the proposed turbine fans and PVC vapor collection piping are provided in
Attachment F.

Monitoring Points
The proposed monitoring points are to be constructed with 1-in slotted PVC pipe identical to the
monitoring points for the 2315 N. Davidson Building (refer to description in Section 2.2.1). The
monitoring point locations were chosen to provide representative coverage across the building slab
and in locations that will be accessible for future vacuum monitoring events. In addition, one
clean-out will be installed on the pipe within the suction trench to provide access for future
maintenance, if warranted.

15
M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
3.0 Quality Assurance / Quality Control

For quality assurance and quality control (QA/QC) purposes, inspections will be conducted during
each phase of system installation activities for each VIMS. A breakdown of the required
inspections for each building is provided below.

• Inspection of suction points and suction trenches prior to concrete repair/replacement;
• Inspection of suction points and trenches after installation and concrete has been repaired;
• Inspection of above-grade riser duct piping;
• Inspection of monitoring points and suction trench clean-outs; and
• Inspection of the fans (both buildings) and vacuum alarm system (2315 N. Davidson
Building only).

Note that additional inspections will be conducted for the 421 E. 26th Building if the VIMS is
converted to an active system as determined by the efficacy testing (Section 4.0). Furthermore, if
future upfit activities of the proposed office space in the 2315 N. Davidson Building is performed
after installation of the VIMS in this area, additional inspections must be conducted during upfit
activities to verify the installed VIMS has not been impacted.

Each inspection will be performed by, or under direction of, the design engineer certifying the
VIMS Plan. The inspections will include field logs and photographs for each section of slab that
will be included in final reporting. The engineer certifying the report, or designee, will provide
DEQ with 48-hour notice prior to conducting the inspections. Please note that 48-hrs notice to
DEQ may not be possible in all instances (for example, if a concrete pour needs to happen within
24 hours due to weather concerns).

4.0 Post-Construction and Pre-Occupancy System Effectiveness Testing

System effectiveness testing including influence tests and indoor air sampling activities are
described in the following sections.

4.1 System Influence Testing

Prior to building occupancy, post-installation influence testing will be conducted on each building
to provide evidence that the VIMS is or will provide sufficient depressurization below the slab as
described below.

2315 N. Davidson Building
The proposed VIMS in the 2315 N. Davidson Building includes an active system with proposed
PressureTech PT-16 fans. Therefore, the pre-occupancy influence test for this building will be
conducted with the installed fans to determine the vacuum levels below the slab. Pressure
differential will be measured at extraction fan locations and pressure monitoring points for the
building slab. Note, while pilot testing has already been conducted in this building to aid in design
of the VIMS, the additional testing will be conducted following the building retrofit activities. The
layout of pressure monitoring points for this building are on Sheet VM-1 in Attachment B. In
addition to the pre-occupancy influence test, the installed Sensaphone Sentinel alarm system, or
similar approved alarm, will be tested to verify proper function.

While any measurable vacuum below the slab indicates that vacuum influence is present in that
area, vacuum measurements of at least 0.016 in-WC (4 Pa) will attempt to be achieved because
this is the minimum vacuum deemed acceptable by DEQ to demonstrate adequate sub-slab
depressurization is occurring.

421 E. 26th Street Building
The proposed VIMS in the 421 E. 26th Street Building includes a passive system. Therefore, the
pre-occupancy influence test for this building will be conducted to determine if communication
from the risers to the monitoring points can be achieved in the event the system needs to be
17
M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
activated. For the system effectiveness testing in the 421 E. 26th Street Building, one or more
variable-speed vapor extraction fans will be attached directly to riser duct piping. Pressure
differential will be measured at extraction fan locations and pressure monitoring points for the
building slab. Note, while pilot testing has already been conducted in this building to aid in design
of the VIMS, the additional testing will be conducted following the building retrofit activities. The
layout of pressure monitoring points for this building are on sheet VM-4 in Attachment C.

While any measurable vacuum below the slab indicates that vacuum influence is present in that
area, vacuum measurements of at least 0.016 in-WC (4 Pa) will attempt to be achieved because
this is the minimum vacuum deemed acceptable by DEQ to demonstrate adequate sub-slab
depressurization is occurring.

4.2 Indoor Air Sampling Effectiveness Assessment

In order to further assess the effectiveness of the VIMS in each building, pre-occupancy indoor air
samples will be collected from each building. The buildings are intended to be occupied shortly
following completion of the retrofit activities. Therefore, the indoor air sampling events will be
conducted a minimum of two weeks following construction of the VIMS with the fans operating
to allow for representative building conditions during sampling. If possible, based on the
construction schedule, the pre-occupancy indoor air samples will be collected with the HVAC
systems operating.

For the 2315 N. Davidson Building, five indoor air parent samples are proposed to be collected
during the indoor air sampling event. For the 421 E. 26th Building, three indoor air parent samples
are proposed to be collected during the indoor air sampling event. The approximate locations for
the proposed indoor air samples are depicted on Sheet VM-1 (2315 N. Davidson Building) and
Sheet VM-4 (421 E. 26th Building).

Each indoor air sample will be collected in accordance with the DWM VI Guidance using an
individual-certified 6-liter Summa canister over an 8-hour period and analyzed for select VOCs
by EPA Method TO-15. The VOCs for the select analyte list will include compounds that were
18
M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
detected in previous sub-slab vapor samples. The compounds included in the select list are
included in Attachment G.

Each indoor air Summa canister will be connected to either a dedicated sampling cane or placed
on an elevated surface in order to collect the air sample in the breathing zone (approximately 5 ft
above the ground surface). Periodic checks will be conducted to monitor the pressure within the
Summa canisters to ensure adequate sample volume is collected. Following sample collection, the
samples will be shipped to an analytical laboratory under standard chain of custody protocol. The
analytical laboratory will be instructed to report J-flag concentrations for each sample. In addition,
the laboratory will be requested to report results to the lower of the laboratory method detection
limits or the DEQ Non-Residential IASLs. For QA/QC purposes, one duplicate sample and one
background air sample will be collected during each indoor air sampling event. During the
sampling activities, indoor/outdoor air pressure differential will be measured near the start, middle,
and end of the 8-hour sampling period using a manometer sensitive to 0.001 inches of water. In
addition, exterior wind speed, exterior wind direction, indoor/outdoor temperature, and
precipitation (if any) will be recorded near the start, middle, and end of the sampling period. H&H
will also complete a DEQ Indoor Air Building Survey and Sampling Form to record sample
information and building conditions at the time of sampling.

Note that new construction materials such as paint, carpet, etc., which could be sources of VOCs
in indoor air, may cause interference with Site-specific compounds during indoor air sampling.
Therefore, the construction contractor will be requested to provide safety data sheets (SDSs) for
materials used during construction which will be submitted to DEQ if elevated compounds are
detected in indoor air. At a minimum, the contractor(s) shall not use building materials that contain
the chlorinated solvents PCE or TCE.

Indoor Air Effectiveness Reporting
The indoor air sampling results will be submitted to DEQ with the VIMS Installation Report for
each building. If unacceptable risk levels are calculated based on the results of initial indoor air
sampling, DEQ will be notified of the results and next steps prior to submission of the VIMS
Installation Report. Based upon the results of the sampling, H&H will make recommendations in
19
M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
general accordance with DWM VI Guidance. It is anticipated that the recommendations will
consist of one of the following:

• The VIMS is effective, and indoor air sampling will continue at a semi-annual frequency
until a request to DEQ is submitted and approved by DEQ to reduce or terminate sampling
(per the DWM VI Guidance, in the case where calculated cumulative risks are below
1 x 10-4 for potential carcinogenic risk and below a hazard index of 1 for potential non-
carcinogenic risk). Note, at a minimum, three semi-annual indoor air sampling events
(including the pre-occupancy event) will be conducted prior to a request to reduce or
terminate the sampling.

• Additional indoor air sampling is warranted to confirm that the VIMS is effective (per the
DWM VI Guidance, in the case where calculated cumulative risks are greater than
1 x 10-4 for potential carcinogenic risk or above a hazard index of 1 for potential non-
carcinogenic risk). In this case, the type of active fans and other installed system
components will be evaluated to determine if the system can be modified to increase its
effectiveness. In addition, an evaluation of the compounds identified in building materials
from the SDSs will be conducted to see if the detected compounds could be sourced from
building materials.

Note, for the 421 E. 26th Street Building, if additional indoor air sampling is required,
modifications to the existing system will first be evaluated to increase effectiveness (i.e.,
increasing the size of passive wind-driven turbine fans). Should results of post-construction indoor
air testing continue to indicate potential unacceptable vapor intrusion risks to occupants of the
building, active fans will be installed at the discharge end of the riser duct piping (as needed) to
convert the system from passive to active sub-slab depressurization. DEQ will be notified of
alterations to the system.

20
M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
5.0 Post-Occupancy Testing

The VIMS for the retrofit activities at the 2315 N. Davidson Building includes an active VIMS
with electric fans. As such, post-occupancy differential pressure testing is anticipated to verify the
system is effectively depressurizing the sub-slab space. After the retrofit activities are complete
and the building is occupied, vacuum monitoring will be conducted on a quarterly basis and the
results will be submitted to DEQ after each event. After one year of operation with generally
stable vacuum results, a request to reduce the frequency of the vacuum monitoring will be
submitted to DEQ for review and approval. Note, this system includes a continuously monitored
vacuum alarm at each riser. Therefore, if a fan becomes inoperable or proper vacuum is not
achieved, then assessment and repairs of the issue can be promptly conducted.

The VIMS for the retrofit activities at the 421 E. 26th Building includes a passive VIMS with wind-
driven turbine fans. Thus, post-occupancy vacuum monitoring is not planned to be conducted. If
the 421 E. 26th Street building is converted to an active system based on results of post-construction
and pre-occupancy assessment results, mitigation system modifications and plans for long-term
differential pressure monitoring across the slab will be submitted to the DEQ Brownfields Program
for approval prior to implementation. If conversion to an active system is deemed necessary,
specifications for the fans to be used will be submitted to DEQ.

As discussed in Section 4.0, post-occupancy indoor air sampling will be completed on a semi-
annual basis. Following three semi-annual indoor air sampling events (with the pre-occupancy
sampling as the first semi-annual event) with results indicating acceptable risk levels for non-
residential use, a request to terminate sampling will be submitted for DEQ approval.

6.0 Future Tenants & Building Uses

The proposed buildings are planned for restaurant, office, and other commercial uses including
retail, warehousing, entertainment, and brewery or food production facility. After occupancy of
the buildings, the property management company, under direction of the building owner, will be
responsible to maintain the vapor mitigation piping and fans in accordance with the pending NBP
for the Site. The property management company will perform inspections of each VIMS for
damages or evidence that the system is not functioning and shall maintain inspection records on
Site. The inspection shall include a visual inspection of the following:

1. All aboveground piping and slab penetrations where accessible.
2. All rooftop electric and turbine fans.
3. All monitoring points.
4. Overall inspection of floor slab for damage that could indicate issues with the system or
create a pathway for sub-slab vapors to enter the building.

In addition, for the 2315 N. Davidson Building, an inspection of the vacuum monitoring system
and differential pressure sensors shall be conducted to ensure proper functionality and alarm
notifications. In addition, the property management group shall designate a person, or persons, to
be receive the notifications from the alarm system and be knowledgeable with the system to
promptly address the alarm condition.

If vapor mitigation components are damaged or need to be altered for building renovations, the
property management company shall contact a North Carolina PE to oversee or inspect the
activities, and a report will be submitted to DEQ detailing the repairs or alterations. To aid in
identification of the vapor mitigation piping, the mitigation piping will be labeled with “VAPOR
MITIGATION SYSTEM – CONTACT PROPERTY MANAGER”, or similar language, on
accessible piping at intervals of no greater than 10 linear feet.

22
M:\AAA-Master Projects\PAMAKA - PAM\PAM-003 N. Davidson & E. 26th\VIMS\VIMP\to DEQ\Revision 2\24003_North Davidson II_VIMP_05062021_Rev 2.docx
7.0 Reporting

A VIMS Installation Report that documents installation activities associated with the VIMS for
each building will be submitted to DEQ following confirmation that the mitigation system is
installed. The report(s) will include a summary of VIMS installation activities, QA/QC measures,
pre-occupancy system effectiveness testing including indoor air assessment results, inspection
documents, and an opinion as to whether the VIMS was installed in accordance with the DEQ-
approved VIMS Plan. Note, depending on the construction schedule, separate VIMS Installation
Reports may be submitted for the 2315 N. Davidson Street and 421 E. 26th Street buildings.

If future upfit activities impact the installed systems, such as in the proposed office space area in
the 2315 N. Davidson Building, an additional VIMS Installation Report will be submitted to DEQ
to document the upfit activities. Furthermore, reports documenting the future post-occupancy
indoor air sampling activities will be submitted to DEQ following each sampling event.

PressureTech High Suction Radon Fans

PressureTech is changing the game for the radon industry with the introduction of the most effective and energy efficient radon fan ever developed! For the first time ever, a residential radon fan is capable of achieving extraordinary levels of static pressure while operating quietly and efficiently. PressureTech will conquer radon problems under the most challenging conditions including clay soil, compacted sand, and even bedrock.
PressureTech has revolutionized the radon fan industry by utilizing DC motor technology which can achieve much higher air flow and suction than typical radon fans. Until PressureTech, radon fans have been made using outdated and inefficient AC motor technology. The PressureTech radon fan is capable to producing over 5 times more static pressure than the leading radon fans and can do so using a fraction of the electricity! At the heart of the PressureTech fan is an ultra-efficient, computer-controlled direct current motor
with integrated impeller system for years of trouble-free continuous operation.
One of the biggest advantages of PressureTech fans over traditional radon fans is the low voltage motor. In fact, the voltage is so low that most jurisdictions do not require an electrical license or permits to wire the fan!

IMPORTANT NOTICE: PressureTech PT Series Fans have low voltage DC motors and must be used
with the included power converter when connected to standard voltage (110-120V AC). Connecting
fan directly 110/120V power source without power converter will damage fan and void warranty.
See wiring instructions on last page of this manual.
PressureTech’s fans can be used for virtually any radon mitigation or vapor intrusion application, residential or commercial. The pressure adjustment dial allows you to adjust the flow of the system in conjunction with your diagnostic testing to achieve optimal
negative pressure below the slab. With suction capabilities exceeding 10-inches of
water column, there is no project that this fan can’t handle! PressureTech is excited to introduce the radon fan that will put an end to problem houses once and for all! So, don’t delay; try a PressureTech radon fan on your next installation and experience for yourself the future of the radon mitigation industry!
The extraordinary thing about the PressureTech fan is that you don’t have to wait until
you have a problem house to use it. Although it can handle those homes with difficult soil conditions, this fan is quiet and energy-efficient enough to use for your everyday installations.
Using the PressureTech product gives the mitigator a clear advantage over their
competitors. Not only does it have suction capabilities far beyond anything else on the
market, but the motor actually runs on a low voltage current. What this means is that many of the expenses associated with the installation are eliminated. For example, most municipalities do not require a licensed electrician for low voltage wiring. Many of the permits and subsequent inspection fees are not necessary when using this fan. And,
quite frankly, the fact that it is low voltage completely eliminates the risk of electrical
hazards that are associated with wiring higher voltages.
There are a lot of radon contractors out there who are walking a fine line by doing their own wiring of 110volt fans. In most states, this is simply illegal and puts both the homeowner and the installer at risk. This type of liability nightmare can be now be
avoided thanks to the low voltage technology PressureTech is bringing to the table.
The radon industry simply has never seen a product like this. There’s just nothing else like it on Earth! This product could change the game and make those “nightmare” mitigation jobs a thing of the past.
Fan Model Volts Watts Maximum Pressure Maximum Airflow
PressureTech PT8 24V (includes 110V converter) 58-80 8.6″ WC 50 CFM
PressureTech PT16 36V (includes 110V converter) 110-170 17.4″ WC 67 CFM
PressureTech P25 48V (includes 110V converter) 255-298 25.2″ WC 82 CFM

PressureTech PT8
With PressureTech’s introduction of the PT8 Radon Fan, the radon industry has finally turned the
corner into modern-day technology! The PT8 was designed with two things in mind: unmatched
performance and unmatched energy efficiency. Thanks to recent developments in DC motor
technology, PressureTech has been able to create an in-line fan that is capable of achieving OVER
8 INCHES OF SUCTION while using only 60 watts of power! The motor is also low voltage, so wiring
the fan doesn’t require a licensed electrician or permit in most jurisdictions. The PT8 is ultra-quiet,
efficient, and extremely effective at more than doubling the pressure field extension (PFE) you
achieve below the slab, compared to the other “high suction” radon fans that are on the market.

PressureTech PT16 & PT25
PressureTech has taken “high suction” to another level by introducing the PT16 and PT25 radon
mitigation / vapor intrusion fans. With static pressure capabilities up to 25 inches of water column,
this compact in-line fan outperforms loud, bulky box fans that are commonly used for commercial
radon mitigation and vapor intrusion projects. The PT Series has many advantages over other fans
thanks to the revolutionary DC motor technology that PressureTech has introduced. Direct Current
(DC) motors are capable of much higher speeds and run more efficiently than traditional fan motors.
The result is higher suction, higher airflow, and lower electrical consumption. By using less
electricity, these fans save your clients money in operating costs and will outlast traditional motors
that tend to burn out much sooner due to excessive heat. Because of lower electrical consumption
than Alternating Current (AC) motors, DC motors run at much lower temperatures which extends the
running life up to 5 times longer.
PressureTech PT Series Radon / Vapor Fan Installation and Operating Instructions

Installation Instructions

1. After interior portion of radon system piping is installed and routed to the outdoor
wall of the building, the radon fan must be installed in-line with the piping. NOTE:
Always install the fan in an upright position to avoid moisture accumulation in the
housing.
2. Using an appropriate rubber connector or pipe reducer coupling, securely
connect the inlet portion of the fan to the vertical riser of the outdoor piping.
Tighten the metal clamps on the both side of the connector to ensure that fan is
adequately secured to the pipe.
3. Build the exhaust stack which will be installed on the outlet of the fan.
4. Attach the exhaust stack to the outlet of the fan using an appropriate rubber
connector or pipe reducer coupling. Attach the exhaust stack to the exterior of
the building so it is securely held by pipe clamps to avoid excess weight/stress
being applied to the fan.
5. Install the power converter in appropriate location. Do not connect power to the
power converter until the fan is completely wired.
6. Remove the cap from the fan electrical box.
7. Connect the wires from the power converter to the wire terminals in fan electrical
box using appropriate connectors. NOTE: Outdoor wiring should be enclosed in
outdoor rated conduit.
8. Once all wire connections are secure in the fan electrical box, connect the power
converter to the power source and check to make sure the fan is running.
9. Once confirmed that the fan is running, check all connections and electrical cover
to ensure that the installation is secure.
10. Activation and troubleshooting: If fan is not running, check any disconnect
switches to make sure they are in the ON position. If the fan does not activate
from a power switch, check the wiring inside of the fan electrical box to make
sure no connections were broken or wired improperly. Also, check the circuit
breaker for the outlet that system is plugged into to confirm that it hasn’t tripped.

Operating Instructions

PressureTech PT Series radon / vapor fans are intended to run continuously to
maintain healthy air within the building. Once the radon system is installed and fan
is activated, power should never be disconnected except to service or replace the
fan.

Power Converter

The PressureTech PT Series radon / vapor fans have low voltage DC motors, so a
power converter must be installed to convert the 110V power source to a low voltage
current. The power converter can be wired anywhere between the fan and power
source and is rated for both indoor and outdoor applications. Simply connect the
positive (red) and negative (black) DC wires to the fan. Then, connect the hot
(black), neutral (white) and ground (green) wires to your 110V power source or
utilize flexible plugged cord to plug into an outlet when located within 6-feet of the
power supply location.

1.4. Seal around all plumbing, conduit, support columns or other penetrations that come through the VaporBlock® membrane. The Raven VaporBoot Pipe Boot System is the recommended sealing method. (Includes 25 pre-cut VaporBlock® pipe boots along with 1 roll of VaporBoot Tape). (Fig. 3 & 4)
Pipe boots may also be fabricated from excess VaporBlock® membrane (Fig. 3 & 4) and sealed with VaporBoot Tape or VaporBond Tape (sold separately).
Reminder Note: All holes or penetrations through the membrane will need a patch cut to a minimum of 6” from the opening in all directions.
To fabricate pipe boots from VaporBlock® excess material (see Fig. 3 & 4 for A-E):
A) Cut a square large enough to overlap 6” 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) Use VaporBoot Tape or VaporBond 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.
VaporBond Tape (option) - Tape completely around the pipe overlapping the to get a tight seal against the pipe.
E) Complete the process by taping over the boot perimeter edge with VaporBond Tape to create a monolithic membrane between the surface of the slab and moisture sources below and at the slab perimeter. (Fig. 3 & 4)

1.5. For side-by-side multiple penetrations (option 1);
A) Cut a patch large enough to overlap 6” in all directions (Fig. 5) 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 the patch material over penetration to achieve a tight fit and form a lip (Fig. 6).
D) Tape around each of the penetrations and the patch with VaporBond 4” Tape. (Fig. 7) For additional protection apply an acceptable polyurethane elastomeric sealant around the penetrations. (Fig. 8)
1.6. Holes or openings through VaporBlock® are to be repaired by cutting a piece of VaporBlock® 6” larger in all directions from the opening. Seal the edges of the patch with VaporBond Tape.

1.6. POUR-N-SEAL™ method of sealing side-by-side multiple penetrations
(option 2):
A) Intall 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 relase
liner from the back of foam strip and adhere to the vapor barrier. Form
a complete circle to contain the POUR-N-SEAL™ materials (Fig. 11).
D) Once mixedm pour contents around the pipe penetrations. If
needed, a brush or plat wooden stick can be used to direct the
sealany completely around penetrations creating a complete seal.
E) DO NOT leave excess POUR-N-SEAL™ in plastic container for longer
than the time it takes to pour sealant.

VAPORBLOCK® REPAIR INSTRUCTIONS
1.7. Proper installation requires all holes and openings are repaired
prior to placing concrete. When patching small holes, cut a piece of
VaporBlock® large enough to overlap the hole 6” in all directions
(smallest patch will be 12” x 12”). Place patch material over the
center of the hole and tape over the patch perimeter with 4” wide
VaporBond Tape (Fig. 14-16).
Fig. 16
Fig. 15Fig. 14
1.8. When installing VaporBlock® 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 by cutting a strip of VaporBlock® 12” wide and centering it
over the cut. Once in place, tape around the perimeter with 4” wide
VaporBond Tape.
VAPORBLOCK® PROTECTION
2.1. When installing reinforcing steel and utilities, in addition to the placement of concrete, take precaution to protect VaporBlock®. Carelessness during installation can damage the most puncture–resistant membrane. Sheets of plywood cushioned with geotextile fabric temporarily placed on VaporBlock® 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® from puncture.
2.3. Avoid driving stakes through VaporBlock®. If this cannot be avoided, each individual hole must be repaired.
2.4. To avoid penetrating VaporBlock® when installing screed supports, utilize non-penetrating supports such as the Mako® Screed Support-System (Fig. 18).
2.5. If a cushion or blotter layer is required in the design between VaporBlock® 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.
2.6. VaporBlock® Vapor Barrier can be identified on site as blue in color printed in black ink with the following logo and classification listing (Fig. 19).
Note: To the best of our knowledge, unless otherwise stated, these are typical property values and are intended as guides only, not as specification limits. Chemical resistance, odor transmission, longevity as well as other performance criteria is not implied or given and actual testing must be performed for applicability in specific applications and/or conditions.

UNDER-SLAB INSTRUCTIONS:
1. Stego Wrap can be installed over an aggregate, sand, or tamped
earth base. It is not necessary to have a cushion layer or sand base,
as Stego Wrap is tough enough to withstand rugged construction
environments.
2. Unroll Stego Wrap over the area where the slab is to be placed. Stego
Wrap should completely cover the concrete placement area. All joints/
seams both lateral and butt should be overlapped a minimum of 6”
and taped using Stego® Tape.
NOTE: The area of adhesion should be free from dust, dirt, moisture, and
frost to allow maximum adhesion of the pressure-sensitive tape.
3. ASTM E1643 requires sealing the perimeter of the slab. Extend vapor
retarder over footings and seal to foundation wall, grade beam, or
slab at an elevation consistent with the top of the slab or terminate at
impediments such as waterstops or dowels. Consult the structural
engineer of record before proceeding.
SEAL TO SLAB AT PERIMETER:*
NOTE: Clean the surface of Stego Wrap to ensure that the area of adhesion is
free from dust, dirt, moisture, and frost to allow maximum adhesion of the
pressure-sensitive adhesive.
a. Install Stego® Crete Claw® Tape on the entire perimeter edge of
Stego Wrap.
b. Prior to the placement of concrete, ensure that the top of Stego
Crete Claw Tape is free of dirt, debris, or mud to maximize the
bond to the concrete.
IMPORTANT: Please read these installation instructions completely, prior to beginning any Stego Wrap installation. The
following installation instructions are based on ASTM E1643 - Standard Practice for Selection, Design, Installation, and Inspection
of Water Vapor Retarders Used in Contact with Earth or Granular Fill Under Concrete Slabs. If project specifications call for
compliance with ASTM E1643, then be sure to review the specific installation sections outlined in the standard along with the
techniques referenced in these instructions.

FIGURE 5: MULTIPLE PIPE PENETRATION SEALING
STEGO WRAP PIPE PENETRATION REPAIR DETAIL:
1: Install Stego Wrap around pipe penetrations by slitting/cutting material as needed. Try to minimize the void space created.
2: If Stego Wrap is close to pipe and void space is minimized then seal around pipe penetration with Stego Tape and/or Stego Mastic.
(See Figure 4a)
3: If detail patch is needed to minimize void space around penetration, then cut a detail patch to a size and shape that creates a 6”
overlap on all edges around the void space at the base of the pipe. Stego Pre-Cut Pipe Boots are also available to speed up the installation.4: Cut an “X” the size of the pipe diameter in the center of the pipe boot and slide tightly over pipe.
5: Tape down all sides of the pipe boot with Stego Tape.6: Seal around the base of the pipe using Stego Tape and/or Stego Mastic. (See Figure 4b)

5. INSTALLATION
PREPARATION:• A test application simulating the project environment should always be done prior to final usage of Stego Mastic.• All surfaces should be dry and free of loose materials, oils and other contaminants. The surfaces should be cleaned in the same fashion as the test surface in order to ensure proper results.• Store above 40°F, and apply above 40°F and below 100°F.
PENETRATIONS:To repair penetrations in Stego Wrap, cut Stego Wrap just big enough to fit over and around the penetration so as to minimize void space. Liberally apply Stego Mastic around the penetration to keep the integrity of the membrane intact. Stego Mastic can be applied from sausage tubes with a standard sausage gun and/or from pails by brush, roller, or trowel.
NOTES: 1) If needed to minimize void space around penetrations, utilize a detail patch of Stego Wrap or Stego® Pre-Cut Pipe Boot to
fit over the penetration and seal the patch/boot with Stego® Tape prior to applying Stego Mastic. 2) Solvent-based products should
not be applied over this product. 3) Clean all tools with kerosene and/or oil-based cleaners.
For additional information, please refer to Stego’s complete installation instructions.

FEATURES AND BENEFITS
STEGO® MASTIC 20-OUNCE SAUSAGE TUBE
Stego Mastic Sausage Tubes are ideal for vapor barrier
repairs and small installations that don’t require a full
pail of Stego Mastic. No surplus goes to waste.
Sausage tubes save time, money and are more
environmentally responsible. They increase yield,
reduce waste and the package can be recycled.
Place the Stego Mastic Sausage
Tube inside the gun
Press the trigger as needed to bring
the top of Stego Mastic Sausage Tube
to the edge of the gun chamber
STEGO MASTIC SAUSAGE TUBE AND MASTIC GUN
STEGO MASTIC 20-OUNCE SAUSAGE TUBE
Cut, poke or slice a small hole
in the Stego Mastic Sausage
Tube just below the metal clip
Place the nozzle over the top of the
chamber/mastic tube and screw the
lid back over and onto the mastic gun
Sausage tubes allow for Stego Mastic to be used
with a mastic applicator gun for more precise
handling and control and once applied, the mastic
can be spread.
Stego Mastic is ready to apply
Same as #3, single pipe shown
Apply Stego Mastic liberally
(~2 inch width and minimum 60-mils
depth) behind where Stego Wrap will
terminate
Where multiple pipes are close
together, place mastic around and
between all individual pipes
If Stego Mastic is applied unevenly at
first pass, it can be evened out with a
trowel or by hand
Place Stego Wrap into place
Stego Mastic should completely
seal the edge of the wrap
to the penetrations
Completely sealed pipe penetration
Utilize Stego Term Bar or other means
(e.g. concrete, backfill) to provide
consistent, continuous pressure to the
Wrap-Mastic interface
