Viper Venom Barrier is the first line of defense against damaging water vapor and soil gas threats existing below the concrete slab.

Viper Venom Barrier is a blown barrier film manufactured using 7-layer, co-extrusion technology. When properly installed, Viper Venom Barrier is designed to resist below slab water vapor and harmful soil gases that threaten the indoor air quality of the building’s occupants. It is made from virgin high density polyethylene (HDPE), low density polyethylene (LDPE) and ethylene vinyl alcohol (EVOH). EVOH resin is the latest resin technology used as a barrier layer against moisture and gas intrusion. Viper Venom Barrier 20-mil offers high impact strength as well as superior resistance to gas and moisture transmission.

Viper Venom Barrier far exceeds the Class A , B and C requirements established by ASTM E 1745 (Standard Specification for Plastic Water Vapor Retarders Used in Contact with Soil or Granular Fill Under Concrete Slabs), the most recognized industry standard for under-slab vapor barrier/retarders.
