VAPORBLOCK® is a high-performance under-slab vapor barrier designed to retard moisture migration through concrete slabs-on grade. VAPORBLOCK® vapor barriers exceed ASTM E-1745 Class A, B, and C requirements for plastic water vapor retarders used in contact with soil or granular fill under concrete slabs. VAPORBLOCK® is excellent for applications requiring a material with ultra-low moisture permeability that is also resistant to decay and degradation.
VAPORBLOCK® vapor barriers are available online in 10 mil and 15 mil. VAPORBLOCK® 10 and 15 mil are not radon barriers.
10 Mil VAPORBLOCK® is stocked in roll sizes of 14′ x 210′, and 15 mil VAPORBLOCK® is stocked in 14′ x 140′ rolls.
If you require a radon barrier, we recommend the 20 mil VAPORBLOCK® PLUS vapor barrier. It is a dual-sided gold and white, seven-layer, coextruded vapor barrier with EVOH resins resistant to radon, methane, and moisture transmission.
