VAPORBLOCK ® 20 mil

VAPORBLOCK® Series consist of high-performance underslab vapor barriers designed to retard moisture migration through concrete slabs. This product is made from state-of-the-art polyethylene resins that provide superior physical and performance properties that far exceed ASTM E-1745 (Plastic Water Vapor Retarders Used in Contact with Soil or Granular Fill Under Concrete Slabs) Class A, B and C requirements.

High tensile strength, unequaled puncture resistance, ultra-low moisture vapor permeability as well as resistance to decay make VaporBlock one of the most effective underslab vapor barriers on the market today! Available in 20 mil for optimal project flexibility.
