VAPORBLOCK® Series consist of high performance underslab vapor barriers designed to retard moisture migration through concrete slabs-ongrade. 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 6, 10 and 15 mil thicknesses to best meet required performance specifications.

VAPORBLOCK® PLUS™ Series consist of seven-layer co-extruded barriers made from state-of-the-art polyethylene and EVOH resins to provide unmatched impact strength as well as superior resistance to gas and moisture transmission. VaporBlock Plus is a highly resilient underslab / vertical wall barrier designed to restrict naturally occurring gases such as radon and/or methane from migrating through the ground and concrete slab. VaporBlock Plus is more than 100 times less permeable than typical high-performance polyethylene vapor retarders against Methane, Radon and other harmful VOCs. VaporBlock Plus is one of the most effective underslab gas barriers in the building industry today, far exceeding ASTM E-1745 (Plastic Water Vapor Retarders Used in Contact with Soil or Granular Fill Under Concrete Slabs) Class A, B and C requirements.
