Abstract: Compositions for forming an improved vapor mitigation barrier are contemplated, such compositions being formed as an aqueous mixture of an asphalt component and a latex component, with the latex component including a chemically resistant latex, the chemically resistant latex being an acrylonitrile butadiene copolymer, an elastomeric fluoropolymer, or both. Such compositions, when cured and formed into a vapor mitigation barrier, may be seen to substantially mitigate diffusion of chlorinated hydrocarbons across the barriers. Also contemplated are methods for forming such vapor mitigation barriers, as well as vapor mitigation barrier products formed via the application of such compositions to various substrates.

Abstract: Barriers for improved vapor mitigation are contemplated, such barriers being formed as a cured latex-asphalt mixture applied to the metal surface of a metallized substrate. The latex-asphalt mixture, prior to curing, comprises an emulsion of an asphalt component, a latex component, and water. Such barriers may be seen to substantially mitigate diffusion of chemical contaminants across the barriers in the form of gas or liquids. Also contemplated are methods for forming such barriers, whether fabricated off-site for installation on site, fabricated in-situ.
