Barrier-Bac

Barrier-Bac Vapor Retarders are high performance under slab vapor retarders developed specifically for the concrete construction industry to retard moisture migration through concrete slabs. They may also be used to control radon, methane, sulphates and many other soil contaminants.

Barrier-Bac vapor retarder products are mechanical interface vapor retarders that meet ASTM E 1745 requirements. These products are comprised of three-layer, co-extruded, biaxially oriented, cross-laminated, polyolefin membranes manufactured only with virgin resins. Our products are independently tested, ensuring that our customers get the highest quality vapor retarders every time.

The ribbed surface of our vapor retarders creates a mechanical interface that, when overlapped and sealed, locks the membrane in place and reduces shifting. Engineered sealing tape takes the same profile as our ribbed membrane and produces a superior mechanical and adhesive seal. This double sealing process greatly reduces the water vapor drive between our membranes over the competition’s flat membrane seams.
