VaporLock-m is a system consisting of TUFF-N-DRI® MV polymer-enhanced asphalt barrier that is seamlessly spray-applied to the substrate. A highly protective thickness of at least 44 mils dry is required. Additional thickness may be required based upon local code or engineering consideration. The barrier’s flexibility enables it to withstand thermal expansion and contraction with no compromise in performance.
VaporLock-m™ is a unique system that uses our superior barrier membrane applied to a geotextile fabric, or other substrate, to prevent methane from entering the building through the foundation slab or other treated surfaces.
