Meadows Perminator Underslab Vapor Barrier

PERMINATOR underslab vapor barrier is a new generation of polyolefin-based resin/chemical technology.

PERMINATOR provides the vapor barrier industry with a highly effective, economical choice for helping to reduce the penetration of moisture and water vapor through the slab into the structure, thereby helping to reduce fungus, mildew, and mold growth.

PERMINATOR also helps reduce radon gas from entering the structure.

PERMINATOR is tough enough to withstand normal construction jobsite conditions and traffic. It will not crack, puncture, snag, split, or tear easily.

PERMINATOR helps meet and maintain the maximum slab moisture transfer rate of 3 lb./1000 ft.2/24 hours, as allowed by the flooring industry’s specifications.

PERMINATOR is available in 10 mil and 15 mil thicknesses. Both versions are furnished in 200’ (61 m) long rolls.

PERMINATOR’s 12’ wide (15 mil) and 15’ wide (10 mil) rolls require fewer seams in application. Installation is quick and easy. All joints/seams, both side and end, should be overlapped 6” and taped using 4” wide PERMINATOR TAPE. PERMINATOR rolls fast and smoothly over level tamped soil or compacted fill.
