INSTALLATION

4

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 Barrier should be unrolled to completely cover the pour area. Vapor barrier sheets can be joined using Barrier-Bac White Bond Tape.

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