Impermeable are an ideal use on brownfields and other contaminated sites as an engineering control for pollution containment. As a certified installer of various types of gas and vapor barrier systems, HEPACO can provide installation and design assistance to complete these complex projects.

HEPACO installs a variety of seamless cold spray applied, water-based, and VOC-free membranes and venting systems which provide a barrier against vapor intrusion into structures on brownfields or other environmentally impaired sites. HEPACO also installs various 2-part odorless, VOC-free vapor intrusion coating systems that consist of chemically resistant materials to protect existing floor slabs and structures from the threat of contaminant vapor intrusion.
