LOW PERMEANCE,
HIGH PERFORMANCE

Barrier-Bac’s 15 mil vapor barrier is a strong, under-slab option for the construction industry that protects against moisture, mold, radon, and other soil contaminants. It is used in projects of high requirements in water vapor permeance, tensile strength and puncture resistance. Our patented process creates a barrier that exceeds Class A, B, and C of ASTM E-1745 specifications.
