Addendum to Vapor Intrusion Mitigation System (VIMS) Design December 17, 2018Atherton Mill Redevelopment
Wood Project: 6228-12-0051
Section 1. Introduction
Based on historical assessment data that identified volatile organic components (VOCs) in sub-
slab soil vapor and groundwater at the subject property, a “Vapor Intrusion Requirement Zone”
was established and outlined in the Environmental Management Plan (EMP) approved by the
North Carolina Department of Environmental Quality (NCDEQ), Division of Waste Management
(DWM), Brownfields Program (BFP) on December 12, 2016. The Vapor Intrusion Mitigation
System (VIMS) for new construction (dated June 8, 2018) was approved by the BFP on June 12,
2018.
Atherton Mill (E&A), LLC (Prospective Developer) and Crescent Communities, LLC are
constructing additional retail, residential and parking structures on the property.The new
construction consists of a 6-story slab-on-grade, mixed-use building located to the south of the
existing 2000 South Boulevard building. The new building (2100 South Boulevard) will generally
consist of commercial/retail space on the lower level with open-air parking. Residential-use space
will be on the second floor and above. The approved construction package provided product
information for a Geo-Seal®46-mil Vapor Intrusion Barrier System and Vapor-Vent®Soil Gas
Collection Systems with Aura passive ventilator pipe caps on each riser pipe.
Geo-Seal®Vapor Intrusion Barrier system was not installed beneath two elevator shafts and two
stairwells at the subject property. The locations of these structures is shown on Figure 1.
Section 2.Design Basis
In accordance with the (BFA) Brownfield Agreement for the property, vapor mitigation measures
will be installed in newly constructed buildings within the “Vapor Intrusion Requirement Zone”.
Wood proposes that Retro-CoatTM Vapor Intrusion Coating be applied to the top of the slab in the
elevator and stairwell areas shown on Figure 1.For the elevator shafts, the coating will be
applied to the concrete floor at the base of the shaft and the concrete walls of the shaft extending
to approximately the ground floor grade elevation.
Information and specifications on the Retro-CoatTM products are included as an Appendix A,and
includes: manufacturer product data sheets,product description, product specifications, and
installation instructions. Wood will perform oversight of the installation and document the as-built
conditions during installation in accordance with the manufacturer’s requirements.
Section 3.Quality Assurance/Quality Control
Atherton Mill (E&A), LLC will retain Wood to provide field quality assurance/quality control
(QA/QC) inspections during application of the Retro-CoatTM vapor barrier coating. The
Addendum to Vapor Intrusion Mitigation System (VIMS) Design December 17, 2018Atherton Mill RedevelopmentWoodProject: 6228-12-0051
inspections will be performed by qualified, manufacturer-trained/certified personnel under the
supervision of the design engineer, and will include field logs and photographs. Wood personnel
will either perform or arrange for calcium chloride moisture testing of the slab so that the
appropriate primer can be recommended. The primer and the Retro-CoatTM Vapor Intrusion
coating will be applied by a manufacturer-approved contractor. Wood will provide notice (at least
48 business hours) to the BFP prior to inspections.
Section 4. Post-Construction/Pre-Occupancy System Effectiveness Testing
Because the Retro-CoatTMVapor Intrusion coating will be applied to the top surface of the
concrete slabs, Wood does not propose pilot/influence testing be performed.
The purpose of the QA/QC inspections described in Section 3 is to verify the effectiveness of
the VIMS. Further evaluation of the VIMS’ effectiveness will be accomplished by collecting and
analyzing post-construction indoor air quality (IAQ) samples from the two stairwells and elevator
shafts shown on Figure 1 prior to occupancy.
Section 5. Post-Occupancy Testing
Because the stairwells/elevator shafts will not be utilized as “occupied” tenant spaces, Wood
does not propose post-occupancy pressure testing. Furthermore, since 2016, Atherton Mill
(E&A), LLC’s consultant, Wood, performed semi-annual monitoring of the IAQ in tenant spaces
in the adjacent building equipped with Geo-Seal®VIMS. The monitoring results have not
identified concentrations of contaminants of concern (CoCs) equal to or above the approved
target monitoring goals for indoor air, suggesting effective mitigation of the intrusion of vapors
with Geo-Seal®VIMS components and installations.
If the results of the post-construction/pre-occupancy IAQ testing do not identify constituents of
concern at concentrations that exceed the target indoor air monitoring goals, then no further IAQ
testing will be performed.The post-construction/pre-occupancy IAQ results will be entered into
the DWM Risk Calculator to determine if additional testing is warranted.
Section 6. Future Tenants & Building Uses
The stairwells/elevator shafts will not be utilized as “occupied” tenant spaces. If Atherton Mill
(E&A), LLC performs modifications to these areas, the modifications will be documented in a
report provided to the BFP.
Addendum to Vapor Intrusion Mitigation System (VIMS) Design December 17, 2018Atherton Mill RedevelopmentWoodProject: 6228-12-0051
Section 7. Reporting
A description of the vapor intrusion mitigation activities described in this addendum will be
included in the report prepared for the VIMS installation. The VIMS installation report will be
sealed by a Professional Engineer, and submitted to the BFP for review and approval. The
report will summarize the installation, QA/QC measures, post-construction/pre-occupancy
system effectiveness testing, and provide an opinion of whether the VIMS was installed in
conditions consistent with the VIMS design and objectives. Certain components of these
reporting requirements including indoor air sampling may be performed and reported under a
North Carolina Licensed Geologist (LG) seal. In the appendix section, the report will include as-
built drawing(s), inspection logs including photographs and field logs, and safety data sheets for
materials used during construction that could contribute to background indoor air contamination.

Chemical Resistance

Vapor Intrusion Coating System for Existing Structures
Product Description
The Retro-Coat™ (patent pending) Vapor Intrusion
Coating System is a complete product line that consists of
chemically resistant materials to properly protect existing
structures from the threat of contaminant vapor intrusion
without the need for additional concrete protection.
Developed by the R&D team of Land Science
Technologies™, the Retro-Coat system has been subjected
to rigorous testing procedures to prove its ability to combat
the most aggressive chemical vapors. The main component
of the Retro-Coat system is the Retro-Coat coating which is
a two part, odorless, no VOC, 100% solids coating.

Retro-Coat finishes to a high gloss, easy-to-clean surface
that is impervious to vapor and moisture transmission.
Available in a variety of colors, Retro-Coat can be applied
on damp as well as dry concrete, concrete masonry units,
tile, brick and metal. For enhanced slip resistance, a
suitable aggregate can be added. In addition, other
additives or materials can be utilized to achieve a desired
performance or aesthetic look.

Typical Application
Retro-Coat is suitable as a barrier to block contaminated
vapors from entering existing structures. Particular uses
include coating the horizontal surfaces of existing structures
where contamination under, or adjacent to, a structure can
potentially migrate inside the structure and create a vapor
encroachment condition. This condition is most commonly
found when the existing structure was operated as a dry
cleaner, gas station, manufacturing facility or located in
close proximity to any structure where carcinogenic
chemicals were utilized.
A typical application consists of a minimum 20 mil thick
system; consisting of two 10 mil coats of Retro-Coat at 160
SF/gallon per coat and is recommended along with a 6 mil
coat of Retro-Coat PRIMER. The typical 20 mil application
can withstand forklift traffic, other machinery and even act
as secondary containment. However, if Retro-Coat may be
exposed to more harsh conditions over a longer period of
time, thicker applications ranging from 60 mil to ¼ -inch may
be more suitable.
In either application, Retro-Coat is a traffic bearing surface
and does not need a protective course placed over it.

Retro-Coat Advantages

• Our R&D team developed all of the
Retro-Coat system components
specifically for vapor intrusion
protection in existing structures

• Retro-Coat is resistant to both TCE and
PCE, the vast majority of coatings
cringe at such aggressive chemicals

• Retro-Coat is a wearing surface,
meaning no additional concrete
protection is necessary

• No odor and fast cure time reduce
building downtime

• Carpet, tile, linoleum or other floor
coverings can be applied directly over
Retro-Coat, if desired

• Eliminates the need to remove the
existing slab and when combined with
in-situ treatment, lowers overall
remediation cost

• Retro-Coat can increase the
performance of an existing active sub-
slab depressurization system

• Retro-Coat can aid in the retiring of
existing active systems

• Available and installed by Land
Science Technologies certified
contractors

Installation
Particular care must be taken to follow those instructions precisely to assure proper installation. These instructions
pertain to a standard 20 mil application; please contact us if the desired application is different.

1. New concrete should be allowed to cure a minimum of 28 days and/or be checked with a rubber mat or plastic sheet to
ensure adequate curing time has occurred.
2. All surfaces to be covered should be power washed, shot blasted, acid etched, scarified or sanded to present a clean,
sound substrate to which to bond to. The prepared surface should have a ph of 7.
3. Any bugholes and cracks wider than 1/8” should be filled with Retro-Coat PREP and allowed to dry before coating. More
severely damaged concrete or other special conditions will require the proper Retro-Coat product.
4. When installing the standard 20 mil application of Retro-Coat, apply a 6 mil coat of Retro-Coat PRIMER and
allow to dry prior to applying the initial coat of Retro-Coat. Priming may not be necessary when Retro-Coat
is applied to a thickness greater than 20 mils. On new concrete or old concrete with an open porosity and on
wood surfaces apply Retro-Coat PRIMER and allow to dry.
5. The two Retro-Coat ingredients should be mixed in the prescribed ratios, using a low speed “jiffy-style” mixer,
(maximum 750 rpm). Mix Part A for about 1 minute then, add Part B and mix until uniform in color and consistency (at
least one additional minute.)
6. Do not mix less than the prescribed amount of any ingredient or add any solvent to the mix.
7. Apply the mixed Retro-Coat material with a short nap roller, a squeegee or a brush. Apply
approximately 160 SF per gallon per coat to achieve 10 mils of coating.
8. Apply a second coat while the first coat is still tacky if using spike shoes or dry enough to walk on, but before 7
hours at 75oF. If the first coat has set and is no longer tacky then the first coat should be sanded before
recoating.
9. A suitable aggregate may be broadcast onto the surface after backrolling to provide more anti-slip profile to the finished
surface. It is advisable to test various types and sizes of aggregate to achieve the desired finished profile.

Product Specification
The specified area shall receive an application of Retro-Coat as manufactured by Land Science Technologies, San
Clemente, California. The material shall be installed by precisely following the manufacturer’s published
recommendations pertaining to surface preparation, mixing and application. The material shall be a low odor, two

Part 2 – Application 2.1 Surface Preparation A. All existing surfaces that will be covered with the systems specified herein should be mechanically ground, shot blasted or sand blasted to yield a minimum 60 grit surface texture. All loosely adhered coatings will be removed. Any grease and other contaminants found on the concrete must also be removed. B. All open cracks 1/2” and greater should be v-notched to a 3/4” width by 1/2” depth and cleaned of any debris. Such cracks should be filled with Retro-Coat Gel and struck off flush with the surrounding surface.
C. Cut back and/or remove any expansion joint backing or filler strips to a minimum of 1 ½” deep. Insert disposable filler in the joints to prevent filling with the overlayment materials and to allow for accurate location of final saw cuts in the overlayment. 2.2 Material Application A. Retro-Coat CAULK 1. Apply Retro-Coat CAULK around the base of all pipe penetrations making sure to fill any gap between the
penetration and concrete slab 2. Apply Retro-Coat CAULK to the joint created between horizontal and vertical transitions. The caulking material should be applied and pressed into the joint filling any gaps that might be present.
B. Retro-Coat PRIMER 1. Apply Retro-Coat PRIMER to all areas at a thickness of 6 mil and allow to dry tack free. In areas where the concrete surface is in need of slight repair or needs to be leveled, a slurry form of Retro-Coat PRIMER
called Retro-Coat PRIMER-S can be applied with a flat squeegee. Retro-Coat PRIMER-S is self priming and does not need to be primed again. C. Retro-Coat
1. Mix Retro-Coat, Part A with a low-speed (<750 rpm) jiffy-style mixer for about 30 seconds, or until uniform in color, then mix in Retro-Coat Coating, Part B for another 30-60 seconds. 2. Dump contents onto floor in a ribbon pattern, squeegee, and then back roll at a coverage rate of 160 SF/gallon to achieve a film thickness of 10 mils.
3. Apply second coat 10 mil coat to achieve a total thickness of 20 mils. Repeat as necessary to achieve specified thickness. 4. If a flooring material will be placed over Retro-Coat after it is applied, or appearance is not a priority, (1) 20
mil coat can be applied. 2.3 Protection of Finished Work A. Prohibit foot traffic on floor for 24 hours after laying (at 70ºF). At 50ºF,this time should be extended to 48 hours. B. Rinse off any chemicals that may come in contact within 7 days of installation with the freshly laid floor immediately. 2.4 Cleanup
A. Properly dispose of all unused and waste materials. B. Tools can be washed in warm, soapy water when wet, but after drying, can only be cleaned by grinding or with a paint stripper. C. Unused resin can be set off with proper amount of hardener and disposed of in regular trash bins.

Part 3 – Quality Control
3.1 Warranty A. Installer shall provide a one year warranty against delamination, chemical attack and normal wear and tear. B. Manufacturer will provide a one year material warranty. 3.2 Quality Control A. Installer shall use a notched squeegee to apply Retro-Coat to the specified mil thickness and calculations shall be done to determine if the correct amount of material has been applied. Retro-Coat contains 100% solids at the time of application; therefore no material shrinkage will occur during the curing process. One gallon will cover 80 square feet. B. A wet mil film gauge can be used to spot check the Retro-Coat thickness to make certain the minimum 20 mil thickness has been applied, though some discretion should be used because high points or low points on the
underlying surface can adversely affect the thickness measurements. 3.3 Floor Care A. The standard smooth surface of Retro-Coat should be cleaned on a regular basis by damp mopping the floor with conventional commercial cleaners. It is important to first remove any grease or oils by a suitable cleaner, preferably a citrus based cleaner. Rinse with clear water to help eliminate film buildup and then allow to dry. Never use abrasive powder cleaners like Ajax or Comet as they tend to scratch the floor. B. Additional steps can also be taken to prolong the look and life of a seamless floor:
1. Protect the floor during transference of heavy equipment 2. Educate the drivers inside the building the importance of avoiding “jack-rabbit” starts and stops, as well as keeping the metal forks lifted
3. Regular cleaning should take place as to not allow the buildup of abrasive material, such as sand or dirt, on the coating 4. Eliminate all metal wheels
5. Change over to light-colored polyurethane wheels 6. Do not slide heavy metal totes, drums or bins across the floor
7. Immediately hose down chemical spills, especially on newly laid floors.

PRODUCT
DATA SHEET
Retro-Coat™ GEL

Product Description
Retro-Coat™ GEL is a three part, 100% solids epoxy
patching material primarily designed for vertical and
overhead applications. Its smooth, creamy consistency
enables the user to skim coat surfaces that are irregular or
pockmarked.

Retro-Coat GEL has virtually no odor and adheres well to
damp as well as dry concrete and masonry surfaces. Unlike
cementitious or acrylic-based patch material it can be
recoated in as little as six hours after application at room
temperature.

Product Application
Retro-Coat GEL is most commonly used to fil bug holes,
crevices and cracks, as well as repairs to vertical surfaces
such as, concrete columns and vertical walls. Retro-Coat
GEL also serves as a toweled-on skim coat for vertical wall
applications.

Installation
Please refer to our Application Specs for detailed instructions. Particular care must be taken to follow those instructions
precisely to assure proper installation.
1. All surfaces must be cleaned by acid etching, grinding, rough sanding or needle blasting. All loose or flaking coatings and other
materials must be removed. All oils, fats, greases or chemically contaminated concrete must be removed.
2. No priming is necessary, as Retro-Coat GEL is a self-priming material.
3. Mix the contents of the Part A and Part B containers in a clean, plastic bucket with a slow speed paddle mixer or electric drill for
about one minute. Then add in Part C slowly for another minute or so, until the mixture is uniform in color and
consistency. Only mix amount of material that can be applied within stated pot life.
4. Use a clean margin trowel or spatula to apply the Retro-Coat GEL. The blade should be large enough to span the depression; use
a 1-1/2” blade for filling cracks.
5. Press the Retro-Coat GEL firmly into place in a wiping motion. Use enough material to overfill the opening.
6. Under normal conditions, Retro-Coat GEL can be applied up to 1” depths without sagging. For greater thickness, contact Land
Science Technologies.

Note: Failure to follow the above instruction, unless expressly authorized by Land Science Technologies, will void our
material warranty.

Precautions
1. Do not apply greater than 1” thick at 70oF

PRODUCT
DATA SHEET
Retro-Coat™ PRIMER
Product Description
Retro-Coat™ PRIMER is a low viscosity, two part, 100%
solids epoxy primer. It is virtually odorless and non-toxic.
Retro-Coat PRIMER has excellent damp, as well as dry
adhesion to concrete, masonry surfaces, wood and gyp
board. With a very low viscosity of 250 centipoise, it
readily penetrates porous substrates to provide an
excellent mechanical bond. Where faster curing times are
required, specify Retro-Coat PRIMER-FC.

Typical Application
Applied to a 6 mil thickness, Retro-Coat PRIMER provides
an ideal substrate for Retro-Coat, but may not be required
when top coating thickness is greater than 20 mil or a
specific aesthetic look is desired. Prior to the application of
Retro-Coat, Retro-Coat PRIMER should be allowed to dry
tack free to maximize its effectiveness.
In areas where concrete is spalled or needs to be leveled
Geo-Seal PRIMER-S is more appropriate.

Installation
1. Moisture testing is recommended via either the anhydrous calcium chloride moisture vapor emission rate test (ASTM
F1869) and the in-situ relative humidity probe test (RH probe test, ASTM F2170).
2. Concrete must be structurally sound, solid and meet industry standards as defined in ACI Committee 201 Report “Guide
to Durable Concrete.” Surface to be coated with Retro-Coat™ PRIMER MV must be free of moisture-sensitive patching
and leveling materials, adhesive, coatings, curing compounds, concrete sealers, efflorescence, dust, grease, oils and any
other materials or contaminants capable of breaking bond. Concrete surface must be mechanically prepared to an ICRI
Concrete Surface Profile (CSP) of 3-4 (Ref 1). The preferred method to achieve this is by shot blasting. Grinding is
permitted only in areas inaccessible to shot blasting or for edging purposes. More aggressive surface profiling may be
required to remove contaminants. Acid etching is not permitted.
3. Upon completion of the shot blasting and grinding, the concrete slab must be vacuumed free of all dust, dirt, debris prior
to installing Retro-Coat™ PRIMER MV.
4. Use of sweeping compounds is prohibited as most contain oil and will prevent bonding.
5. Concrete slab may contain additional contaminants that inhibit bonding of a moisture control coatings to the concrete.
Thus, a more aggressive surface preparation, removal of concrete from the surface or removal of organic substances may
be required.
6. Part A and B should be mixed in the prescribed ratio using a low speed jiffy-style mixer (maximum 750 rpm) for at least 60
seconds.
7. Retro-Coat™ PRIMER MV is a proprietary formulation of 100% solids epoxy and no solvents are necessary.
8. Apply the mixed material with a fine nap adhesive roller, squeegee or brush. Apply in two coats at approximately 160-200
SF per gallon each, depending on surface porosity.
9. Allow to dry prior to the application of Retro-Coat.

Note: Failure to follow the above instruction, unless expressly authorized by a Land Science Technologies
Representative, will void our material warranty.

Precautions
1. Retro-Coat™ PRIMER MV is very fast reacting; pour out of bucket immediately after mixing and spread with
squeegee especially at temps greater than 70°F.
2. Recoat windows at 70o: Retro-Coat™ PRIMER MV - 18 hours
3. Never apply Retro-Coat™ PRIMER MV more than 15 mils (100SF/gallon) per pass as it will not cure hard in greater
thicknesses.

Never give anything by mouth to an unconscious or convulsing person. 4.2 Most Important symptoms/effects, acute and delayed:
Signs and Symptoms: Irritation as noted above. Skin sensitization (allergy) may be evidenced by blisters, redness,
or rashes, especially hives. Aggravated Medical Conditions: Preexisting skin and eye disorders may be aggravated by exposure to this
product. Preexisting skin and lung allergies may increase the chance of developing increased allergy symptoms from exposure to this product. Other Health Effects: Based on animal studies, repeated exposure to components of this product may cause damage to respiratory systems. Reports have associated repeated and prolonged occupational exposure to solvents with
permanent brain and nervous system damage. Intentional misuse by deliberately concentrating and inhaling vapors may be harmful or fatal. 4.3 Indication of immediate medical attention and special treatment needed, if necessary:
Note to Physician:
Eyes: Stain for evidence of corneal injury. If cornea is burned, instill antibiotic/steroid preparation frequently. Workplace vapors could produce reversible corneal epithelial edema impairing vision. Skin: This product is a known skin sensitizer. Treat symptomatically as for contact dermatitis or thermal burn. Ingestion: Treat symptomatically. There is no specific antidote. Inducing vomiting is contraindicated because of the irritating nature of the product. Inhalation: This product is a known pulmonary sensitizer. Treatment is essentially symptomatic. An individual having a dermal or pulmonary sensitization reaction to this material must be removed from any further exposure to any isocyanate. Contact a Poison Control Center for additional treatment information. Health studies have shown that many
petroleum hydrocarbons pose potential human health risks, which vary from person to person. As a precaution, exposure to liquids, vapors, mists, or fumes should be minimized.

chemicals spilled on the coating surface. Any change in color or fade in the coatings appearance is due to a PH
change on the coatings surface and is not the result of products “breaking down.”
The standard smooth surface of Retro-Coat should be cleaned on a regular basis by damp mopping the floor
with conventional commercial cleaners. It is important to first remove any grease or oils by a suitable cleaner,
preferably a citrus based cleaner. Rinse with clear water to help eliminate film buildup and then allow to dry.
Never use abrasive powder cleaners like Ajax or Comet as they tend to scratch the floor.
Additional steps can also be taken to prolong the look and life of a seamless floor:
1. Protect the floor during transference of heavy equipment
2. Educate the drivers inside the building the importance of avoiding “jack-rabbit” starts and stops, as well
as keeping the metal forks lifted
3. Regular cleaning should take place as to not allow the buildup of abrasive material, such as sand or dirt,
on the coating
4. Eliminate all metal wheels
5. Change over the light-colored polyurethane wheels
6. Do not slide heavy metal totes, drums or bins across the floor. Use pallets!
7. Immediately hose down chemical spills, especially on newly laid floors, which normally take a full seven
days to fully chemically cure
8. Ask Land Science Technologies the safe window before returning the floor to service. Just because the
floor can safely take foot traffic, does not mean it is ready for motor traffic

Small Repairs
A vital component to floor maintenance is making small repairs to any holes, gouges or cracks that might
develop overtime. Such needs occur due to removal of equipment, moving of walls, additions of drains,
substrate movement and abnormal wear and tear. Repair to such areas can be done quickly and is
recommended to repair such areas before the damaged area increases and results in large-scale repairs and
possibly building downtime. Small kits are available for building maintenance personal to make spot repairs as
needed.

St. Johns-based F.C. Mason company was provided a $1 million CleanMichigan Initiative Brownfields grant from the Michigan Department ofEnvironmental Quality (MDEQ) to move its operations to the formerFederal Mogul manufacturing facility which was vacated in 2008. F.C.Mason Company was founded in 1898 and specializes in manufacturingparts for agricultural, construction and industrial equipment. Theacquisition of the 265,000‐square‐foot facility allows F.C. Mason toexpand operations and bring back valuable jobs to Clinton County.Michigan-based Soil and Materials Engineers, Inc. (SME) was consulted to address the suspected environmental and vapor intrusion concerns resulting from years of manufacturing activities at the site.
Trichloroethylene (TCE) contaminated areas were present in one section of the building. In 2009, in situ chemical treatment of the “hot spot” areas was conducted employing RegenOx® technology (REGENESIS®, San Clemente, CA). However, a vapor intrusion condition was later identified and mitigation was needed. Retro‐Coat was selected to be used in conjunction with an active sub‐slab depressurization (SSD) system. By simultaneously utilizing the two mitigation approaches, SME was able to reduce the number of SSD points in the design and the total area requiring the vapor intrusion barrier coating. MDEQ approved of the plan. A certified Retro‐Coat applicator installed 6 mils of red Retro-Coat Primer and 20 mils of grey Retro-Coat along with a

broadcasted aggregate to provide a non-slip surface. The contrast in color between Primer and Retro-Coat allows the clear
identification of wear over time, prompting repair if needed, and ensuring long‐term protection from vapor intrusion.
Retro‐Coat Vapor Intrusion Coating System is a complete product line that consists of chemically resistant materials to protect existing structures from the threat of contaminant vapor intrusion without the need for additional concrete protection. The Retro‐Coat system has been subjected to rigorous testing procedures to prove its ability to combat the most aggressive chemical vapors. The system is rated for industrial use providing a durable finished surface suitable for vehicular traffic. Retro‐Coat coating technology was specifically developed for vapor intrusion.
Vapor‐Vent is a low profile vent system that can be used in lieu of slotted PVC pipe. The speed of installation and the proximity of the vent to the barrier provide cost savings and performance benefits compared to other technologies.

Historic Building Achieves Site Closure Using
Retro‐Coat™ to Meet Environmental Screening Levels

• Site achieves closure due to the successful Retro‐CoatTM application• Post‐application indoor air data confirmed Retro‐Coat compliance with residential and commercial ESLs• Customized finish met building owner requirements• The application of Retro‐Coat achieved orders of magnitude reduction similar to those of Sub‐Slab Depressurization (SSD) Systems without the need to operate and maintain finicky mechanical systems
Retro‐Coat was selected to mitigate vapor intrusion within a structure built in 1907 that had been impacted by both a former underground storage tank and a local dry cleaner. Indoor air samples taken prior to application showed chlorinated solvent‐based PCE and TCE levels above the Regional Water Quality Control Board Environmental Screening Levels (RWQCB ESL).
Existing wood flooring, CMU block walls, framing obstructions on the wall, and conduits penetrating both the basement floor and walls presented challenges to successfully providing vapor intrusion mitigation to the entire basement area. The age of the structure was also a factor because little was known about how the building was constructed or expansion/improvements made over the years. The building owner sought to provide the future occupants of the building with vapor intrusion protection using a durable and slip resistant coating. Retro‐Coat was applied to the existing wall surface (CMU block walls) and across the floor. Additionally, a silica sand was broadcast across the floor during the Retro‐Coat application to achieve a non‐slip surface.

About the Consultant
•VOCs reduced by 99% within one month of operation
•Achieved site goals of meeting VDEQ and DEH IAQ standards and
rendering home safe for habitation
At a residential site in Virginia, vapor intrusion affected the interior
living space of a private building due to release of heating oil from
an Above Ground Storage Tank (AST) to the sub-slab environment
beneath the structure. Indoor air quality sampling after the release
revealed several petroleum compound contaminants at concentrations
above EPA Residential Screening Levels.
To minimize the displacement of the homeowners for an extended period of time, the VIM system had to produce good indoor air quality results as quickly as possible. Leading environmental firm, Duncklee & Dunham, designed and installed an active, sub-slab vapor mitigation system and sealed the surface of the slab in the interior of the building with 1000 sq. ft. of Retro-Coat™ applied. The active system consisted of vertical vent wells installed in the building slab to a depth just below the bottom of the slab and connected to a manifold. Soil vapors were extracted from the sub-slab environment with an electric radon fan and exhausted to the exterior atmosphere. Retro-Coat primer and sealant were then applied to the entire surface area of the interior building slab to provide supplemental vapor intrusion prevention.
The Retro-Coat Vapor Intrusion Coating System is a complete product line that consists of chemically resistant materials to properly protect existing structures from the threat of contaminant vapor intrusion.
The vapor mitigation system reduced VOCs in the exhaust gas by 99% within one month of operation, and reduced levels of petroleum compounds in indoor air to the extent that the building was suitable for occupancy six weeks after the system startup.
