Vapor Barrier: Concrete is porous and corrosive and can break down normal plastic sheeting and “chemical treated” plastic used by most contractors. Our Vapor Lock barrier is made from materials that are impervious to concrete’s corrosive properties. Underslab Vapor Mat costs 7 times as much as normal plastic sheeting yet is worth every penny when utilized. It truly seals in all ground-born contaminates associated with an unfinished crawl space. Not only is Underslab Vapor Mat the right solution, it is the best solution available, bar none.
“Chemically treated” and normal plastic sheeting is available in various thickness but only Underslab Vapor Mat is truly impervious to the corrosive properties of concrete and will lock out ground born contaminates forever. Guaranteed!
