Vapor Block™ is a high performance under slab vapor retarder designed to retard moisture migration through concrete slabs-on-grade. 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.

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 furnishing in your buildings interior from moisture migration.

Vapor Block™ vapor retarder can also greatly reduce condensation, mold and degradation by controlling water vapor migration.
