Current techniques for removing asbestos- containing fireproofing require the construction of air-tight barriers, labor- intensive scraping of the fireproofing, and the installation of new asbestos-free fireproofing. The DMATM product is the result of a joint development by W.R. Grace & Co. and Department of Energy's Brookhaven National Laboratory. The new technology uses a foamy solution sprayed directly onto asbestos-containing fireproofing. After absorbing into the fireproofing, the foam chemically digests asbestos fibers and dissolves them into harmless minerals. The process is the first to chemically destroy asbestos without first removing the fireproofing.
