This seven-layer co-extruded barrier manufactured from polyethylene and EVOH resin provides resistance to gas and moisture transmissions. PERMINATOR EVOH is a highly resilient underslab barrier designed to restrict gases, such as gasoline, solvents, oils, and hydrocarbons from migrating through the ground and into the concrete slab. The product also protects against naturally occurring gases such as radon and methane.

PERMINATOR EVOH efficiently resists gas and moisture migration as part of a building envelope system. Installation can be across floors, walls, and crawlspaces, reducing condensation, mold, fungus, mildew, and degradation. PERMINATOR EVOH’s seven-layer protection is tough enough to not crack, puncture, snag, split, or tear easily on the construction site.
