Advanced Engineering
Viper Venom 20-mil is our most advanced soil gas vapor barrier for commercial construction. Featuring 7-layer co-extrusion technology and EVOH layer, Viper Venom protects against radon, methane, hydrocarbons and more.
Premium Protection
Viper Venom is made from virgin high-density polyethylene (HDPE), low-density polyethylene (LDPE) and ethylene vinyl alcohol (EVOH). EVOH resin effectively locks out harmful soil gasses, preventing them from migrating into a structure through the concrete slab. Viper Venom boasts high impact strength as well as superior resistance to compromised soil contaminants.
Designed for Brownfield Sites
As cities expand and age, Brownfield reclamation is more critical than ever for efficient use of land and resources. Viper Venom soil gas barrier was specifically designed to help create safe structures and promote building longevity and health in the toughest brownfield environments.
