Vapor retarders save time, money and energy by reducing moisture migration under concrete slabs and foundations, and through inner walls and ceilings. Raven has a wide variety of vapor retarder products to choose from that are readily available.
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.
