Barrier-Bac products: Seam Tape, VB and VBC products

Barrier-Bac has a complete line of under slab vapor barriers including 11 mil, 16 mil, 31 mil Composite and Seam Tape for adhesive sealing.

We offer membranes in two thicknesses: 11 mil (250 gsm) and 16 mil (350 gsm). We also offer each of these products as composites where a non-woven polypropylene geo-textile fabric is laminated to the membrane for increased protection, puncture resistance and friction interface.

Barrier-Bac and Barrier-Bac Composite products exceed the ACI 302 specification (thickness of 10 mil or greater) and have also been tested for permeability using ASTM E 1745 standards.

Seaming of the Barrier-Bac vapor barrier products can easily be accomplished either heat welding or taping. Barrier-Bac seam tape is specifically designed and tested to perform with Barrier-Bac membranes.
