Mint St\1513-1521 Assessments\VIMS Install Report\Report VIMS Installation Completion Report Quality Products Company 1513 S. Mint Street Charlotte, North Carolina Brownfields Project No. 22016-18-060 H&H Job No. LEH-004 1.0 Introduction On behalf of LEH NC Mint, LLC (the Prospective Developer or PD), Hart & Hickman, PC (H&H) has prepared this report to document vapor intrusion mitigation system (VIMS) installation, influence testing, and post-construction sub-slab soil gas assessment activities completed at a portion of the Quality Products Company Brownfields property (Brownfields Project No. 22016- 18-060) located at 1513 S. Mint Street and 1515 S. Mint Street in Charlotte, Mecklenburg County, North Carolina (Site or subject Site). The Site is comprised of three tax parcels (Mecklenburg County Parcel ID Nos. 11908315, 11908316, and 11908317) totaling approximately 0.53-acres and is currently developed with a single-story multi-tenant commercial building with an associated gravel-covered parking area. Proposed redevelopment plans for the Site include upfit and renovations for adaptive re-use of the existing building including spaces for a restaurant, a dentist office, and concert hall. The remainder of the Site will generally be covered with impervious surfaces including parking areas, sidewalks and exterior patios. Renovation of the 1515 S. Mint Street tenant space was completed and documented in the VIMS Installation Completion Report dated July 29, 2022, which was submitted to and reviewed by DEQ. The VIMS Installation Completion Report was approved by DEQ in a Vapor Mitigation Compliance Review letter dated August 10, 2022. The 1513 S. Mint Street tenant space upfit is currently in progress and occupancy for the space is anticipated in early- April with the business set to open in mid-April. A redevelopment Site plan is included in Figure 1. H&H previously completed vapor intrusion assessment activities at the Site to evaluate the potential for vapor intrusion prior to redevelopment. Results of previous vapor intrusion assessment activities are documented in the Limited Phase II Environmental Site Assessment (ESA) 2 S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report Report (dated March 2, 2018), and the Brownfields Assessment Report (dated October 22, 2019). Tabular summary of the vapor intrusion assessment sample results and sample location maps are provided in Appendix A for ease of reference. In addition, H&H conducted a baseline mercury sub-slab soil gas assessment at the site to establish pre-mitigation baseline mercury vapor concentrations. Results of the mercury vapor assessment are documented in H&H’s Mercury Vapor Assessment Report (dated October 27, 2020). During the assessment, four sub-slab samples were collected. Mercury was not detected in three of the samples, and was detected at an estimated concentration at one location (SSV-3, 0.52 µg/m3) well below the DEQ DWM Non-Residential Vapor Intrusion Soil Gas Screening Level of 26 µg/m3. Based on these concentrations, H&H recommended no further assessment of mercury vapor on the site. DEQ found the findings in the above report to be in compliance with the Vapor Intrusion Mitigation Plan for the property in a Mercury Assessment Report Compliance Review dated December 3, 2020. The draft Brownfields Agreement for the Site includes the following land use restriction (LUR) No. 15.g.: No enclosed building may be constructed on the Brownfields Property and no existing building, defined as those depicted on the plat component of the Notice of Brownfields Property, may be occupied until DEQ determines in writing that: i. the building is or would be protection of the building’s users, public health and the environment from risk of vapor intrusion based on site assessment data or a site-specific risk assessment approved in writing by DEQ; or ii. the building is or would be sufficiently distant from the Brownfields Property’s groundwater and/or soil contamination based on assessment data approved in writing by DEQ that the building’s users, public health and the environment will be protected from risk from vapor intrusion related to said contamination; or iii. vapor mitigation measures are installed or implemented to the satisfaction of a professional engineer licensed in North Carolina, as evidenced by said engineer’s profession seal on a report that includes photographs and a description of installation and 3 S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report performance of said measures. Any design specification for vapor intrusion mitigation measured shall be approved in writing by DEQ in advance of installation and/or implementation of said measures. The design specifications shall include methodology(ies) for demonstrating performance of said measures. In accordance with the LUR No. 15.g., the DEQ Brownfields Program approved Environmental Management Plan (EMP) dated October 29, 2019, and conversations with DEQ Brownfields personnel in a meeting held on October 7, 2019, the PD has elected to install a vapor intrusion mitigation system (VIMS) in the Site building. The DEQ-approved Vapor Intrusion Mitigation Plan (VIMP), dated August 3, 2020 includes installation of a passive sub-slab depressurization system in the 1513 and 1515 S. Mint Street building and post-installation sub-slab soil gas sampling. Updated VIMS drawings were submitted to DEQ to account for an addition to the 1513 S. Mint Street space and the updated VIMS drawings were approved by DEQ via email on June 6, 2022. This report documents installation of the VIMS and post-construction sub-slab soil gas assessment for the 1513 S. Mint Street tenant space. A discussion of VIMS installation activities is provided in Section 2.0, a summary of sub-slab soil gas assessment activities is provided in Section 3.0, and summary and conclusions based on the results of the VIMS installation and soil gas assessment activities are provided in Section 4.0. 4 S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report 2.0 VIMS Installation and Influence Testing 2.1 VIMS Installation The DEQ-approved VIMP includes installation of VaporBlock® Plus 20 (VBP20) vapor barrier manufactured by Raven Industries (Raven). The vapor barrier was installed above the base course layer and beneath the concrete. VBP20 is an ASTM-certified 20-mil, multilayer, chemically resistant vapor barrier, designed to minimize the migration of volatile organic compounds (VOCs). The vapor barrier was installed per manufacturer installation instructions by the contractor. Technical specifications and installation instructions obtained from Raven for the VBP20 vapor barrier and associated accessories are provided in Appendix B. VBP20 was installed to cover the base course layer below the slab area of the proposed ground floor slab. The vapor barrier was attached/sealed to concrete and masonry surfaces of footings and existing walls (see Sheet VM-2). Two-sided butyl seal tape was used to attach/seal the vapor barrier to concrete or masonry surfaces. Seams within the building footprint have a minimum 12- inch overlap and were sealed with VaporSeal™ tape. Small puncture holes were sealed with VaporSeal™ tape. Larger holes, tears, or other damage were repaired using a patch of vapor barrier that overlaps the damaged area and then taped along the seams. In areas where utility penetrations (i.e., piping, columns, ducts, etc.) are present and the use of taping was not practical or was deemed “ineffective” by the design engineer, Pour-N-Seal ™ was poured into a form to patch the penetration with a vapor tight seal. The VIMP also includes installation of a passive mitigation system beneath the slab of the 1513 S. Mint Street building to reduce the potential for structural vapor intrusion into the non-residential space. The passive system includes a polyvinyl chloride (PVC) piping network below the slab of the building. Three vertical exhaust risers that extend to the roof of the building were connected to the sub-slab piping network. Empire Model TV04SS (stainless steel) wind-driven turbine fans were installed in-line with the risers on the roof of the building to enhance passive vapor mitigation and discharge sub-slab vapors to the atmosphere above the roof of the building. The VIMS layout 5 S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report is shown in the as-built drawings (Sheets VM-1 and VM-2) included as Appendix C. Product specification sheets for the turbine fans and sub-slab piping are included in Appendix B. To enhance sub-slab vapor transmission and collection effectiveness, a uniform layer of high permeability stone (#57 stone) was installed directly below the concrete slab to allow for air movement beneath the entirety of the slab. Sub-slab vapor collection piping (4-inch diameter) was installed completely within the high permeability stone layer. The VIMP also includes three vacuum monitoring points (depicted on the as-built sheets in Appendix C). The vacuum monitoring points were used to measure the pressure differential between ambient air and the sub-slab during influence testing activities described below, and for collection of sub-slab soil gas samples. During installation of the VIMS in the 1513 S. Mint Street tenant space, H&H conducted inspections during various phases of construction to confirm the VIMS was installed in accordance with the DEQ-approved VIMP. Inspections were completed during the following phases of installation: • after installation of sub-slab horizontal collection piping system within the gravel base; • following placement and sealing of the vapor barrier, prior to pouring the concrete building slab; and • after installation of vertical exhaust riser pipe and turbine fan installations Based upon periodic inspections completed during VIMS installation activities, the VIMS was installed in accordance with the DEQ-approved VIMP. VIMS details and specifications, and a VIMS as-built drawing which depicts the VIMS layout are included in Appendix C. A photographic log of installed VIMS components is provided in Appendix D. 2.2 VIMS Influence Testing On May 2, 2022, H&H completed influence testing for the system to evaluate sub-slab vacuum communication and to document sufficient depressurization can be obtained below the slab should 6 S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report the system be activated with electric fans in the future (if warranted). DEQ considers 4 Pascals (Pa), or 0.016 inches of water column (in-WC) differential pressure the minimum vacuum needed for an active depressurization system to effectively treat potential structural vapor intrusion. VIMS vacuum influence pilot testing included use of AMG Eagle Extreme electric fans to model an active depressurization system. Differential pressure measurements were collected at each vacuum monitoring point using a Dwyer series 475 Mark III Digital manometer (capable of measuring 0.001 in-WC or 0.25 Pa) to establish baseline conditions prior to operation of the AMG Eagle Extreme electric fans. Following collection of baseline differential pressure measurements, the electric fans were turned on and differential pressure measurements were collected at each monitoring point. Results of the influence tests indicated sub-slab vacuum measured at the monitoring points ranged from 0.893 in-WC to 1.070 in-WC in the tenant space, which demonstrates sufficient vacuum can be achieved below the slab of each of this portion of the building. The locations of the permanent monitoring points (denoted by MP nomenclature) are shown in VM-1 (Appendix C). The pilot test field data is included in Appendix E. 3.0 Sub-Slab Soil Gas Assessment Activities Following successful installation of the VIMS, H&H collected two sub-slab soil gas samples for laboratory analysis from the 1513 S. Mint Street tenant space. The sub-slab assessment activities were conducted in accordance with the DEQ-approved VIMP and the DEQ DWM Vapor Intrusion Guidance (Guidance) dated March 2018. 3.1 Sub-Slab Soil Gas Sampling On March 17, 2023, H&H collected two sub-slab soil gas samples from permanent monitoring points in the 1513 S. Mint Street tenant space. The sampling was performed following VIMS installation activities and over two weeks after completion of the riser piping and installation of the wind-driven turbine fans. The sub-slab soil gas samples were collected from permanent monitoring point locations MP-4 and MP-6, as shown on VM-1 in Appendix C. One duplicate sub-slab soil gas sample (MP-DUP) was collected for quality assurance/quality control (QA/QC) purposes from the MP-4 parent location during the sampling event. The duplicate sample was 7 S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report collected utilizing a laboratory supplied stainless-steel sampling “T” which allows for the simultaneous collection of two sub-slab soil gas samples from a single location. To collect the sub-slab soil gas samples, Teflon sample tubing was secured to a 2-inch expandable well cap with a sampling port that was secured onto the PVC monitoring point. The tubing was connected to an airflow regulator and laboratory-supplied batch-certified 1.4-liter stainless steel Summa canister. The air flow regulator was preset by the laboratory to collect a soil gas sample over a period of 10 minutes. Prior to sample collection, H&H conducted a leak test at each monitoring point by placing a shroud around the monitoring point, expandable well cap, and sampling train including the Summa canister. The air within the shroud was flooded with helium gas and concentrations were measured with a calibrated helium detector. Helium concentrations within the shroud were maintained between approximately 15.8% and 16.1%. A GilAir vacuum pump was connected to the sample tubing outside of the shroud and used to purge a minimum of three volumes (monitoring point and sample train) of soil gas into a Tedlar® bag at each sampling point. The helium gas detector was used to measure helium concentrations within the Tedlar bag sample to confirm helium concentrations in the sample were less than 10% of that measured within the shroud. Results of the helium leak checks indicate that short-circuiting at the monitoring points or within the sampling train were not present. Soil gas sampling field forms completed by sampling personnel are included in Appendix E. Following successful leak checks, the air flow regulators were opened to allow collection of the sub-slab soil gas samples. Vacuum in the Summa canisters was monitored during the sampling event to confirm adequate sample volume was collected at each monitoring point location. Upon completion of sample collection, the air flow regulator was closed to the Summa canister. The canisters were labeled with the sample identification, beginning and ending times, pressure measurements, and the requested analysis. The canisters were then placed in laboratory supplied shipping containers and delivered to Waypoint Analytical Laboratories (Waypoint) under standard chain of custody protocols for analysis of volatile organic compounds (VOCs) by EPA Method TO-15. 8 S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report 3.2 Sub-Slab Soil Gas Sampling Results The sub-slab soil gas sample analytical results are summarized in Table 1. The results were compared to the DEQ DWM Non-Residential Vapor Intrusion Sub-Slab and Exterior Soil Gas Screening Levels (SGSLs) dated January 2023. The laboratory analytical report with chain of custody record is provided as Appendix F. The monitoring point soil gas sample analytical results indicate that several compounds were detected at concentrations above laboratory method detection limits (MDLs) in each sample, but below the DEQ DWM Residential and Non-Residential Vapor Intrusion SGSLs. Naphthalene was detected at concentrations above DEQ DWM Residential Vapor Intrusion SGSLs but below Non- Residential Vapor Intrusion SGSLs in samples collected from both monitoring points. Trichloroethene (TCE) was detected at concentrations below both the DEQ DWM Residential and Non-Residential SGSLs in samples MP-4 and MP-DUP. TCE was also detected at concentrations above DEQ DWM Non-Residential Vapor Intrusion SGSLs in sample MP-6. No other compounds were detected above DEQ DWM Residential or Non-Residential Vapor Intrusion SGSLs. The DEQ DWM Vapor Intrusion SGSLs are very conservative and based on a target carcinogenic risk (TCR) for potential carcinogenic risks of 1 x 10-6 and a hazard quotient (HQ) of 0.2 for potential non-carcinogenic risks. The DEQ and EPA acceptable risk level for potential carcinogenic risks is a cumulative lifetime incremental cancer risk (LICR) of 1 x 10-4 or less and the acceptable level for non-carcinogenic risks is a cumulative hazard index (HI) of 1 or less. The HI is the sum of HQs for each target analyte. H&H utilized the DEQ Risk Calculator (January 2023) to confirm that there are no potential vapor intrusion risks at unacceptable levels. H&H modeled a worst-case scenario by using the highest concentrations of any compound detected below the slab in the 1513 S. Mint Street tenant space based on a non-residential use scenario to conservatively evaluate potential vapor intrusion risks. The calculated cumulative LICR and HI values are provided in Table 1, and a copy of the completed DEQ Risk Calculator is provided in Appendix G. 9 S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report As shown in Table 1, results of the worst-case risk calculations indicate a calculated cumulative LICR of 1.0 x 10-6 and a HI value of 0.26. The calculated cumulative residential use LICR and HI values are within the DEQ and EPA acceptable levels. These risk calculator results confirm that compound concentrations detected below the slab do not pose vapor intrusion risks at unacceptable levels within the 1513 S. Mint Street tenant space with a passive VIMS. 10 S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report 4.0 Summary and Conclusions Upfit of the 1513 S. Mint Street tenant space has been completed at the Quality Products Company Brownfields property (Brownfields Project No. 22016-18-060) located in Charlotte, Mecklenburg County. The 1515 S. Mint Street tenant space was redeveloped in 2022. A separate report was submitted to document installation of the VIMS in this space on July 29, 2022 and was approved by DEQ in a letter dated August 10, 2022. During redevelopment of the 1513 S. Mint Street space, H&H conducted VIMS installation inspections to confirm the system was installed as designed and completed post-installation sub- slab soil gas sampling activities to evaluate efficacy of the system. The VIMS installation inspections and post-installation sampling activities were completed in general accordance with the DEQ-approved VIMP. A brief summary of the VIMS installation and post-installation soil gas assessment activities is provided below. VIMS Installation VIMS installation has been completed for 1513 S. Mint Street tenant space and consists of a passive sub-slab depressurization system with vertical extraction piping to the roof connected to wind-driven turbine fans. During installation of the VIMS, H&H personnel, under direction of a North Carolina licensed Professional Engineer, conducted inspections during each stage of installation. Results of the installation inspections indicate that the VIMS was successfully installed in general accordance with the DEQ-approved VIMP. Influence testing for the space confirmed that adequate vacuum is obtainable for the purpose of active vapor mitigation (if warranted in the future). Sub-Slab Vacuum H&H completed vacuum influence pilot testing in March 2023 following installation of the VIMS piping network, but prior to the complete installation of the vertical riser piping and wind-driven turbines. Vacuum measurements collected during the pilot testing activities (range from 0.895 in- WC to 1.070 in-WC) indicated that vacuum communication beneath the slab was achieved with adequate differential pressure levels. 11 S:\AAA-Master Projects\Lischerong Enterprises and Holdings (LEH)\S. Mint St\1513-1521 Assessments\VIMS Install Report\Report Sub-Slab Soil Gas Assessment Following installation of the VIMS and completion of interior construction activities, H&H collected three sub-slab soil gas samples (MP-DUP, MP-4, and MP-6) from the 1513 S. Mint Street tenant space to evaluate potential vapor intrusion risks. Laboratory analytical results of the sub-slab soil gas samples indicate that naphthalene was detected at concentrations above the DEQ DWM Residential Vapor Intrusion SGSLs in samples MP-4/MP-DUP and MP-6. TCE was also detected above DEQ DWM Residential and Non-Residential Vapor Intrusion SGSLs in sample MP-6. H&H utilized the DEQ Risk Calculator (January 2023) to calculate the cumulative carcinogenic and non-carcinogenic risks under a hypothetical worst-case residential-use scenario by utilizing the highest concentration of each compound detected in the tenant space sub-slab soil gas samples. Although TCE was detected above DEQ DWM Non-Residential Vapor Intrusion SGSLs in sample MP-6, hypothetical worst-case non-residential use risk calculator results indicate a calculated cumulative LICR of 1.0 x 10-6 and a calculated cumulative HI of 0.26. The calculated cumulative non-residential use LICR and HI values are within the DEQ and EPA acceptable levels. Based on the VIMS installation inspections, influence testing, and post-installation sub-slab soil gas sampling results, the VIMS is effectively mitigating potential vapor intrusion risks at the Site. The sub-slab soil gas to indoor air risk calculator results confirm that risks are below acceptable levels.

Seal around all plumbing, conduit, support columns or other penetrations that come through the VaporBlock® Plus™ membrane. 1.4a. Method 1: Pipes four inches or smaller can be sealed with Raven VaporBoot Plus preformed pipe boots. VaporBoot Plus preformed pipe boots are formed in steps for 1”, 2”, 3” and 4” PVC pipe or IPS size and are sold in units of 12 per box (Fig. 3 & 5). Pipe boots may also be fabricated from excess VaporBlock® Plus™ membrane (Fig. 4 & 6) and sealed with VaporBoot Tape or VaporSeal™ Tape (sold separately). 1.4b. Method 2: To fabricate pipe boots from VaporBlock® Plus™ excess material (see Fig. 4 & 6 for A-F): A) Cut a square large enough to overlap 12” in all directions. B) Mark where to cut opening on the center of the square and cut four to eight slices about 3/8” less than the diameter of the pipe. C) Force the square over the pipe leaving the tightly stretched cut area around the bottom of the pipe with approximately a 1/2” of the boot material running vertically up the pipe. (no more than a 1/2” of stretched boot material is recommended) D) Once boot is positioned, seal the perimeter to the membrane by applying 2-sided Raven Butyl Seal Tape in between the two layers. Secure boot down firmly over the membrane taking care not to have any large folds or creases. E) Use VaporBoot Tape or VaporSeal™ Tape to secure the boot to the pipe. VaporBoot Tape (option) – fold tape in half lengthwise, remove half of the release liner and wrap around the pipe allowing 1” extra for overlap sealing. Peel off the second half of the release liner and work the tape outward gradually forming a complete seal. VaporSeal™ Tape (option) - Tape completely around pipe overlapping the VaporBlock® Plus™ square to create a tight seal against the pipe. F) Complete the process by taping over the boot perimeter edge with VaporSeal™ Tape to create a monolithic membrane between the surface of the slab and gas/moisture sources below and at the slab perimeter.

B) Once barrier is in place, remove soil or other particles with a dry cloth or a fine broom to allow for improved adhesion to the POUR-N-SEAL™ liquid. C) Create a dam around the penetration area approximately 2” away from the pipe or other vertical penetrations by removing the release liner from the back of a 1” weather stripping foam and adhere to the vapor barrier. Form a complete circle to contain the POUR-N-SEAL™ materials (Fig. 11). D) Once mixed, pour contents around the pipe penetrations. If needed, a brush or a flat wooden stick can be used to direct the sealant completely around penetrations creating a complete seal (Fig. 12-13). E) DO NOT leave excess POUR-N-SEAL™ in plastic container for longer than the time it takes to pour sealant. Fig. 12 Fig. 13 Fig. 11 Option 2 VAPORBLOCK® PLUS™ REPAIR INSTRUCTIONS 1.7. Proper installation requires all holes and openings are repaired prior to placing concrete. When patching small holes, simply cut a 12” long piece of 12” wide VaporSeal™ tape. Remove release liner and center over the opening. Apply pressure to create a seal (Fig. 14-15). 1.8. When installing VaporBlock® Plus™ around pipe penetrations, vertical columns, electrical ducts and other obstructions, you will find it necessary to cut it to the nearest outside edge. This cut can be easily sealed with 12” wide VaporSeal™ tape, by simply centering it over the cut, 6” on either side. Once the tape is placed correctly, apply pressure to assure a complete seal (Fig. 16). Reminder Note: All holes or penetrations through the membrane will need to be patched with 12” VaporSeal™ Tape. Fig. 14 Page 4 of 5 Fig. 15 2.1. When installing reinforcing steel and utilities, in addition to the placement of concrete, take precaution to protect VaporBlock® Plus™. Carelessness during installation can damage the most puncture–resistant membrane. Sheets of plywood cushioned with geotextile fabric temporarily placed on VaporBlock® Plus™ provide for additional protection in high traffic areas including concrete buggies. 2.2. Use only brick-type or chair-type reinforcing bar supports to protect VaporBlock® Plus™ from puncture. 2.3. Avoid driving stakes through VaporBlock® Plus™. If this cannot be avoided, each individual hole must be repaired per section 1.7. 2.4. To avoid penetrating VaporBlock® Plus™ when installing screed supports, utilize non-penetrating support, such as the Mako® Screed Support System (Fig. 17). Avoid driving stakes through VaporBlock® Plus™. If this cannot be avoided, each individual hole must be repaired per figures 14-15. 2.5. If a cushion or blotter layer is required in the design between VaporBlock® Plus™ and the slab, additional care should be given if sharp crushed rock is used. Washed rock will provide less chance of damage during placement. Care must be taken to protect blotter layer from precipitation before concrete is placed.

Effort should be given to minimize large gaps, this will also reduce the amount of POUR-N-SEAL™ necessary to complete an acceptable seal.2STEP Seal any cut openings that were required to install VaporBlock® around the penetrations with 12” wide VaporSeal™ gas / moisture barrier tape or by overlaying a piece of VaporBlock® centered over the cut and taped around the perimeter. Clean the area to be sealed by removing any debris. 3STEP To help concentrate the sealant around the pipe penetration, a dam can be formed 2” away from the pipe grouping with an adhesive backed 1” weather stripping foam. Complete the preparation of all areas requiring sealant to maximize the pot life of POUR-N-SEAL™ epoxy, prior to mixing the two components. 4STEP Avoid Contact with skin by wearing protective gloves and clothing. Only mix the amount of material that can be used within the pot life of the epoxy, approximately 36 minutes at 73° F. Premix each component prior to combining. Pour “A” and “B” components together and thoroughly mix using a low speed drill with a mixing paddle. Scrape the sides and bottom to assure a consistent blend. If not thoroughly mixed, the set time will be greatly extended. 5STEP Once mixed, pour contents around the pipe penetrations, if needed a brush or flat wooden stick can be used to direct the sealant completely around all penetrations and overlap the moisture/gas barrier to form a continuous seal. Immediately dispose of any remaining mixed POUR-N-SEAL™ epoxy left in the container to avoid excessive heat buildup. Depending upon the temperature, POUR-N-SEAL™ should be tack free in approximately 5 hours. 6STEP Penetrations should be sealed, once filled, covering the entire surface inside the foam dam. Allow to cure prior to pouring concrete to assure a continuous seal without displacing the POUR-N-SEAL™ epoxy. Leave foam dam in place. See SDS for complete safety precautions. For professional use only. NOTE: Store in dry environment between 40º F and 80º F (4º C-27º C). Do not allow product to freeze. Prior to use, keep overnight to precondition at a temperature between 70° F to 80° F. Protect from moisture. ENGINEERED FILMSP.O.

Algonquin Street Sioux Falls, SD 57104 PRODUCT DESCRIPTION POUR-N-SEAL™ is a gray two-part medium viscosity high strength epoxy used to seal around multiple pipe penetrations in tight areas where pipe boots are not practical, when installing VaporBlock® moisture and gas barriers. TECHNICAL DATA Applicable Standards: • ASTM (American Society for Testing and Materials) • ASTM C881 Standard Specification for Epoxy-Resin-Base Bonding Systems for Concrete • ASTM D695 Standard Test Method for Compressive Properties of Rigid Plastics • ASTM D638 Standard Test Method for Tensile Properties of Plastics • ASTM C882 Standard Test method for Bond Strength of Epoxy-Resin Systems Used with Concrete by Slant Shear • ASTM Standard Test Method for Deflection Temperature of Plastics Under Flexural Load in the Edgewise Position • ASTM D570 Standard Test Method for Water Absorption of Plastics MATERIAL PREPARATIONStore material overnight to precondition at a temperature between 70° F to 80° F prior to use. INSTALLATION 1. POUR-N-SEAL™ is used to seal moisture and gas barriers to multiple pipe penetrations in situations where pipe boots are not able to be installed due to the tight concentration of the pipe penetrations. 2. Install the vapor/gas barrier as close as possible to the penetrations by making a small opening. Effort should be given to minimize large gaps in the barrier next to the penetrations, this will also reduce the amount of POUR-N-SEAL™ necessary to complete an acceptable seal.3. To help concentrate the sealant around the pipe penetration, a dam can be formed around the pipe grouping with an adhesive backed weather stripping foam. One gallon covers 80 sq. ft. at a thickness of 20 mils. 4. Only mix the amount of material that can be used within the pot life of the epoxy, approximately 36 minutes at 73° F. Premix each component prior to combining. Pour “A” and “B” components together and thoroughly mix using a low speed drill with a mixing paddle. Scrape the sides and bottom to assure a consistent blend. 5. Once mixed, pour contents around the pipe penetrations, if needed a brush or flat wooden stick can be used to direct the sealant completely around all penetrations and overlap the moisture/gas barrier to form a continuous seal. Avoid Contact with skin (see SDS for complete safety precautions). Immediately dispose of any remaining mixed POUR-N-SEAL™ epoxy left in th container to avoid excessive heat buildup. 6. Depending upon the temperature. POUR-N-SEAL should be tack free in approximately 5 hours. STORAGE/SHELF LIFEStore in dry environment between 40º F and 80º F (4º C-27º C).
