Our Mechanical Bond Makes
The Superior Vapor Barrier
Our Barrier-Bac Composite products provide a mechanical bond with concrete through the extra lamination of our geo-textile fabric. When concrete is poured over the composite vapor barrier, the geo-textile lamination adheres to the concrete to prevent pocketing.
Pocketing occurs when soil settlement allows water to migrate between a standard smooth surface vapor barrier and the concrete slab, creating pools of water directly in contact with the slab. Because of the mechanical bond and excellent peel adhesion of Barrier-Bac composite product, pocketing cannot occur. Contractors find this most valuable for projects with a high water table, void-formed slab, or expansive soil conditions.
