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.
