The cross-woven structure distributes force across the entire surface instead of concentrating stress at a single point — the reason our liner resists punctures that tear through standard sheeting.
A dense, extrusion-coated barrier that blocks moisture, radon, and methane migration without losing integrity under tension or temperature extremes.
Built to be pulled, tucked, and stretched into tight corners during install — and still perform at full thickness for the life of the structure.
From standard crawl space protection to extreme-duty commercial applications.
