NW75 Membrane is a 65-mil membrane comprised of a non-woven polypropylene fabric laminated to a rubberized asphalt waterproofing sealant-adhesive. NW75 seals and waterproofs joints and cracks, as well as bridge decks when installed following Polyguard installation guidelines. The open fibers of the non-woven geotextile fabric provide a mechanical bond to the new asphalt overlay, while the rubberized asphalt sealant-adhesive bonds to the existing pavement surface.
