N E T SLAB/HORIZONTAL Vapor Block ® 10, 15 Vapor Block™ 10 and 15 are high performance underslab vapor retarders designed to retard moisture migration through concrete slabs-on-grade. Vapor Block™ 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, low moisture vapor permeability as well as resistance to decay make Vapor Block one of the most effective underslab vapor retarders on the market today! Available in 10 and 15 mil thicknesses to best meet required performance specifications. Vapor Block impedes the transmission of water vapor from traveling upward through a concrete slab-on-grade or through a concrete wall when properly installed. It is extremely important to avoid puncturing a vapor retarder during installation to assure proper performance. Vapor Block’s puncture strength is second to none, withstanding even the most demanding installation conditions. Vapor Block vapor retarders protect your flooring and other moisture sensitive furnishings in your building’s interior from moisture migration. Vapor Block™ vapor retarders can also greatly reduce condensation, mold and degradation by controlling water vapor migration. Common applications include under-slab vapor retarder, crawl spaces, and foundation wall vapor retarder. Vapor Block 10, 15 meets ASTM E-1745 Class A, B, C Standards.

Vapor Block PLUS 20 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. Vapor Block PLUS 20 is more than 100 times less permeable than typical high-performance polyethylene vapor retarders against Methane, Radon and other harmful VOCs.
