Contractor Magazine Article

This recent article by Contractor Magazine discusses proactive steps to mitigate environmental liability risk. Due to the continued need for affordable land in areas accessible to highly populated areas, and fueled by tax incentives, many new construction buildings will be constructed on or near brownfields where chemical releases have occurred. Risks from chemical contamination—including PFAS—are real, but can be mitigated through planning and new technologies. Learn more by reading the article.

Nitra-Seal: Incorporates a nitrile-modified spray-applied core and dual polyethylene sheets

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.

Featured Video: Spotlight on Experience Ryan Miller, East Region Manager

Ryan Miller is the East Region Manager of the Land Science® division of REGENESIS, Inc., and is based on the East Coast. Ryan’s role includes providing technical support in the design and installation of Land Science vapor mitigation systems, and educating the environmental community on the advancements in vapor intrusion barrier technology, implementation, and quality control. Ryan has extensive experience in the environmental consulting industry, most recently working as a New Jersey Licensed Site Remediation Professional (LSRP) focusing on brownfield redevelopment projects and specializing in vapor intrusion mitigation.

Hotel Chain Moves Forward With Brownfield Site Construction

The project site is a modern, climate-controlled self-storage facility that includes all-in-one moving, packing, and storage services for its customers. The building was developed on a former industrial brownfield at the site of a former factory. As part of Maryland’s Voluntary Cleanup Program, the environmental consultant completed a Phase II investigation, finding elevated chlorinated solvent contaminants in the soil gas. The Maryland Department of Environment required the installation of a vapor mitigation system over a portion of the building. However, in working with the consultant, it was ultimately determined that a vapor barrier spanning the entire building footprint would be necessary to protect the future building tenants fully. TerraShield® was specified to provide the highest level of chemical resistance and long-term barrier performance available on the market.

Superior Chemical Resistance Over Any Vapor Barrier on the Market Today

When developing properties on sites with known environmental impacts, one of the biggest issues is the risk to human health. Failure to address these issues can result in adverse health effects and millions of dollars in legal exposure. TerraShield was designed specifically to eliminate risk of exposure by employing innovative technologies to provide best-in-class chemical resistance and durability. Backed by a robust warranty and installed by Land Science-certified applicators, each TerraShield installation is rigorously tested to ensure the quality of every seal and ultimately the complete vapor barrier system installed.
