Description
VAPORBLOCK® is a high performance underslab vapor barrier designed to retard moisture migration through concrete slabs-ongrade. 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.
If you require a radon barrier, we recommend the 20 mil VAPORBLOCK® PLUS vapor barrier. It is a duel-sided gold and white, seven-layer, coextruded barrier with EVOH resins resistant to radon, methane, and moisture transmission.
