Geo-Seal® Receives State Approval From California Department of Toxic Substances Control

Project Highlights

Geo-Seal^® resists contaminant permeation breakthrough for a period 18X longer than simple asphalt/latex membranes
Installation of 22,000 square feet
California DTSC Approved

Project Summary

A senior housing facility was constructed over an existing benzene plume creating a concern for exposure to high levels of benzene vapors. Northgate Environmental, with the approval of the California Department of Toxic Substances Control (DTSC), selected Geo-Seal^® vapor intrusion barrier to mitigate the vapor intrusion risk associated with the property.

Geo-Seal provides triple-layer protection and high puncture resistance by using two chemically resistant high density polyethylene (HDPE) layers encapsulating a spray-applied asphalt/latex membrane. Geo-Seal’s exceptional chemical resistance limits the transmission of volatile organic vapors through the membrane. 22,000 square feet was successfully installed at the site.
