A Cost-Effective Barrier with Superior ConstructabilityMonoShield 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 about MonoShield using the link below.
The Original Composite Barrier System Adapted from Waterproofing MaterialsGeo-Seal is a sub-slab composite barrier system designed for waterproofing and adapted for use in blocking low concentrations of chemical vapors on brownfield sites. Geo-Seal is placed between the building foundation and the soil pad to minimize water vapors and minor concentrations of chemical vapors from permeating through the slab. Geo-Seal is rapidly applied and a broad certified applicator network is available. Learn more about Geo-Seal using the link below.
As risk standards and other compliance issues associated with contaminant vapor intrusion continually evolve, engineered controls like those offered by Land Science provide a practical, cost effective solution to eliminate risks. Recent advances in contaminant vapor intrusion mitigation developed by Land Science have assisted developers, engineering firms, regulators, and land owners by providing technically sound solutions effectively mitigating these issues.

CASE STUDY: Big Box Retail Store Receives “No Further Action” Status after Geo-Seal Application
Project Highlights
- Incorporated the new Illinois Environmental Protection Agency’s (IEPA) Tiered Approach to Corrective Action Objectives (TACO) legislation vapor intrusion regulations
- Geo-Seal® applied to 150,000 square feet of commercial space
- Geo-Seal® application helped obtain a “No Further Action” letter
Project Summary
Geo-Seal was selected to mitigate vapor intrusion at a new retail development in Skokie, Illinois. The former industrial site was contaminated with chlorinated solvents (PCE, TCE, DCE and VC) and regulatory agencies required mitigation. A developer purchased the underutilized 15-acre light industrial business park for redevelopment and initial due diligence investigations identified numerous environmental issues on the property.
Geo-Seal was applied to 150,000-square-feet of retail space and the applicator was able to meet union labor guidelines for the project. Vapor intrusion risks were also mitigated at a fast-food restaurant and bank on-site through the application of Geo-Seal. The site was issued a draft “No Further Remediation” letter with the final letter issued upon completion of the engineered barriers constructed as part of the redevelopment.

Combined Technologies Treat High Vapor and TCE Levels at 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
St. 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.
