Site Conditions / Brownfields / Geo-Seal® EV80
Geo-Seal® EV80 is a 79 mil thick composite membrane that uniquely combines an Ethylene Vinyl Alcohol (EVOH), HDPE and spray-applied polymer-modified asphalt to create a composite vapor intrusion barrier system that addresses a wide range of project conditions and contamination. It is ideal for development projects that are willing to compromise on total system thickness and some barrier durability but still desire a highly chemically-resistant barrier. The Geo-Seal® EV80 system consists of three distinct layers:
- Geo-Seal® EV30
- Geo-Seal® CORE
- Geo-Seal® BOND
Highlights
Geo-Seal® EV30 base is a 31 mil EVOH base course reinforced with a geotextile, which protects the base course from the permeable base layer and creates a strong seal at seams, termination points and penetrations.
Geo-Seal® CORE layer is fluid-applied at 30 mil to the Geo-Seal® EV30 base to create a seamless barrier and increase overall composite system tensile and puncture strength.
Strong mechanical bond that directly adheres the system directly to the foundation slab.
