Install Vapor Barrier Products

Installation Guideline illustrations composite

Inspect base onto which Barrier-Bac is to be installed to ensure a relatively smooth surface. Although Barrier-Bac products are extremely tough, installation is easier and more effective when done over a smooth base. Barrier-Bac may be installed over tamped earth, sand or an aggregate base course.

The Vapor Retarder should be unrolled to completely cover the pour area. White Bonds and/or joints can be joined using either Barrier-Bac BB20T White Bond Tape or with heat welding.

All damages to the Vapor Retarder must be sealed prior to pour. Patch all damaged areas with membrane and sealing tape prior to concrete pour.
