A Proven Vapor Barrier System Now Improved With Nitrile

A Proven Vapor Barrier System Now Improved With Nitrile Nitra-Seal™ is an update/improvement on current vapor barrier systems. An acknowledged weakness in these systems is in the penetration and perimeter termination locations, where spray-applied core material composed of Styrene-Butadiene (SB) latex/ asphalt is used. Nitra-Seal offers a substantial upgrade as it employs a more chemically resistant nitrile latex instead of the more susceptible SB latex. Nitra-Seal is a composite system creating the ideal blend between constructability and chemical resistance by using both high density polyethylene (HDPE) and nitrile-advanced, spray-applied asphalt core.

This case study reviews a pilot test to remove PFAS risk at Camp Grayling, a large year-round military training center in Crawford County, Michigan operated by the Michigan Army National Guard (MIARNG). This innovative approach uses an in situ colloidal activated carbon barrier to eliminate the PFAS exposure pathway and protect the community. Results 170 days post-application show PFAS and PCE reduced to below target levels. Colloidal activated carbon was selected because of the expected rapid reductions of PFAS by removal from the dissolved mobile phase, as well as its lower total project costs when compared to operating a mechanical system over a similar time.

A Cost-Effective Vapor Barrier with Superior Constructability

MonoShield: A Cost-Effective Vapor Barrier with Superior Constructability MonoShield is a chemically resistant and easy-to-apply barrier specifically designed as a preemptive solution for vapor intrusion at brownfield redevelopment sites. It is backed by unparalleled design support and a network of certified applicators who can ensure quality installtion. As with any construction project, but especially with regards to a voluntary preemptive action, cost is often a critical factor; MonoShield was designed with this in mind. One of the most significant advantages is reduced installation time. MonoShield can be installed 30-40% faster than alternate plastic sheeting or HDPE systems. This saves money by reducing contractor costs and shortening the development timeline. Learn more and download the product brochure below.

Combined Technologies Treat High Vapor and TCE Levels at Michigan Facility

lst-michigan-facility

Project highlights

  • Redeveloped facility delivers jobs to Michigan community
  • Simultaneous use of Retro-Coat and Vapor-Vent
  • reduced number of SSD points
  • Approximately 30,000 square feet of Retro-Coat successfully applied
  • Retro‐Coat provided a durable finish for vehicle traffic and heavy equipment in a manufacturing setting

 

 

 

Project summary

lst-michigan-facility-2St. Johns-based F.C. Mason company was provided a $1 million Clean Michigan Initiative Brownfields grant from the Michigan Department of Environmental Quality (MDEQ) to move its operations to the former Federal Mogul manufacturing facility which was vacated in 2008. F.C. Mason Company was founded in 1898 and specializes in manufacturing parts for agricultural, construction and industrial equipment. The acquisition of the 265,00-square-foot facility allows F.C. Mason Company to expand 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.

Technology Description

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.

Retro-Coat™ a New Approach to Mitigating Vapor Intrusion at Brownfield Sites with Existing Structures

Retro-Coat Application Inside Existing Building
Retro-Coat Application Inside Existing Building

Recently, at the Eighth International Conference on Remediation of Chlorinated and Recalcitrant Compounds, organized and presented by Battelle, Dr. Ben Mork, the Director of Research and Development at Land Science Technologies (LST), a Division of REGENESIS, Inc. delivered a formal “Technologies for Tomorrow” luncheon presentation which included subject matter on a new vapor intrusion mitigation product called Retro-Coat™. This new technology is part of a suite of successful vapor intrusion solutions, including the widely used vapor intrusion barrier Geo-Seal®, offered by LST and designed for use on a range of contaminated properties including brownfields.

Retro-Coat is a new, specially formulated concrete coating developed to mitigate vapor intrusion in existing structures. The Retro-Coat material is highly effective in mitigating potentially harmful contaminant vapors resulting from chlorinated solvents and/or petroleum hydrocarbons in groundwater or soil environments. During the presentation, Dr. Mork went into great detail regarding the research and development process, including the new long-term chemical resistance and testing methodologies developed by LST to document the effectiveness of the Retro-Coat material. He also mentioned that more information will be available regarding the details and testing of Retro-Coat in a forthcoming white paper due out later this summer.

Looking beyond the testing and application, Peter Grant, Division Manager for Land Science Technologies, added, “Vapor intrusion represents a lot of uncertainty for building owners. Retro-Coat provides a simple and proven solution to a complex problem. Implementing Retro-Coat can reduce site characterization cost, building mitigation cost and provide the building owner with greater long-term assurance and flexibility in successfully mitigating their vapor intrusion risk.”
