Raven - Gas/Moisture Barriers

Underslab gas barriers are becoming necessary components for sites containing high risk factors for naturally occurring gases. Raven gas/moisture underslab barriers are made from state-of-the-art polyethylene and barrier resins to provide unmatched impact strength as well as superior resistance to gas and moisture transmission. VaporBlock® Plus™ is a seven-layer co-extruded gas and moisture barrier designed to restrict naturally occurring gases such as radon and/or methane from migrating up through concrete slabs.
