This vapor intrusion mitigation case study produced in partnership with Total Vapor Solutions showcases a creative, cost-effective solution that allowed for construction to proceed on a large-scale multi-phase townhome project. The developer planned to construct nine individual buildings on the site, each ranging from 4,000 to 6,000 square feet, with multiple townhouse units inside. Slab-on-grade foundations were set, but construction could not continue without understanding each building’s vapor intrusion risks and creating a plan to provide reliable protection for future residents.

Nitra-Seal™ is a new advanced nitrile composite barrier system. It represents 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.

Nitra-Seal employs a chemically resistant nitrile latex. Nitrile is recognized throughout the environmental engineering industry as being chemically resistant and is often used in personal protective equipment when working on hazardous waste sites (e.g. nitrile gloves). Laboratory testing has shown up to 10X higher chemical resistance when compared to any other vapor barrier material on the market. Download the brochure to learn more about Nitra-Seal.

In this webinar we were pleased to have as a special guest speaker Mark Quimby, Senior Consultant at SME. His presentation discussed case studies of large sites where an innovative preemptive vapor barrier technology was applied to save time and money. The sites discussed were >500,000 square-feet and used an innovative approach to reduce construction time. He was joined by Ryan Miller, East Region Manager at Land Science, who discussed technologies to mitigate vapor intrusion.

Throughout his 14-year professional career, Mark Quimby, Senior Consultant at SME, a leading regional multi-service engineering and consulting firm and valued Land Science client, has established himself as a top expert in the field of assessing and mitigating petroleum, chlorinated solvents, and methane vapor intrusion sites. During this time, he has designed and installed dozens of vapor intrusion mitigation approaches inclusive of sub slab passive venting, multiple types of vapor barriers, active sub slab depressurization, and passive interceptor trenches. In addition, he has secured and managed over $50 million in local, state, and federal incentives that include grants, loans, tax abatements and credits, and tax increment financing.
