Underslab TRM
Underslab TRM is a strong sheet barrier with 8.5 mils high strength polyethylene backing laminated to a 69-mil thick layer of TRM Sealant integrated into a top layer of high strength non-woven geotextile fabric. Total membrane thickness is factory controlled at 95 mils. On the fabric side, a 4" wide lap of waterproofing adhesive compound is left exposed along one edge with a removable silicone coated release sheet. This adhesive is exposed just prior to the installation of the adjacent roll, which creates a 4" wide self-adhesive overlap seam. Underslab TRM is the thickest in the industry, ideal for your most abusive jobsites. When you need a reliable fully-adhered waterproofing with termite barrier, choose Underslab TRM.
