Brownfields Project No. 18015-40-060
H&H Project No. SHR-001

Dear Carolyn:

Hart & Hickman, PC (H&H) has prepared this letter to request approval for vapor mitigation plan
(VMP) modifications at the NoDa Village Apartment Community at the Craighead Road
(Abernethy Lumber) Brownfields property (Brownfields Project No. 18015-40-060) in Charlotte,
Mecklenburg County, North Carolina (Site). On May 24, 2017, the North Carolina Department
of Environmental Quality (DEQ) approved the Vapor Mitigation Plan – Revision 1 (dated May
23, 2017), for the Site.

The requested modifications of this VMP include:
1. using Raven Industries VaporBlock® VB15 (15-mil) vapor barrier in-place of the Stego
Industries 15-mil Stego Wrap®, and
2. separating the vapor mitigation system (VMS) sub-slab piping into multiple sections to
accommodate the planned staged construction of the Site buildings (Building 1 and
Building 2).

Page 2
The VaporBlock VB15 is an equivalent vapor barrier to the Stego Wrap and meets the
requirements for an alternative vapor barrier specified in the approved VMP. A specification sheet
for the VaporBlock VB15 is included as Attachment 1.
Furthermore, during construction planning activities for the proposed Site buildings, the general
contractor indicated both Building 1 and Building 2 will be constructed in phases or sections, with
different completion dates for each section. Therefore, to provide for an effective VMS in each
building section, H&H has proposed to separate the VMS sub-slab piping into sections as shown
on the attached Sheets VMP-1 and VMP-2 (Revision 2). The number of fans and vacuum
monitoring points will remain the same, but the sub-slab piping will stop at the thickened slab
footing for each building section. In addition, in Building 2, fan location F2-8 was slightly moved
from Building 2A to Building 2B to accommodate a more suitable location for sub-slab
depressurization. Please note the modifications to the sub-slab piping are indicated in red on the
attached Revision 2 sheets (Attachment 2).
Please notify us if these changes are acceptable. If you have any questions or require additional
information, please do not hesitated to contact us at 704-586-0007.

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)

1.1. Level and tamp or roll granular base as specified by your architectural or structural drawings. If sharp crushed rock is used, a 1/2” layer of fine grade compactable fill is required between the base and the vapor retarder.
1.2. Unroll VaporBlock® running the longest dimension parallel with the direction of the pour and pull open all folds to full width. (Fig. 1)
1.3. Lap VaporBlock® over the footings and seal with Raven 2-sided Butyl Seal tape. Prime concrete surfaces, when necessary, and assure they are dry and clean prior to applying Raven Butyl Seal Tape. Apply even and firm pressure with a rubber roller. Overlap joints a minimum of 6” and seal overlap with Raven VaporBond Tape.

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.

Option 1
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.
