Mechanical Bond: Reduces Moisture Migration

"Pipe boot" made with Seam Tape and Barrier-Bac VBC250

With the extra lamination of geo-textile fabric, Barrier-Bac Composite products provide a mechanical bond with concrete when placed with geo-textile facing concrete pour. This bond greatly improves slab protection from moisture migration by maintaining close contact with the slab. This is especially valuable for projects with expansive soil conditions; void formed slab and high water table.
