Product Overview
Road/Bridge Application:
A flexible sheet waterproofing material made with SBS (styrene-butadiene-styrene) thermoplastic elastomer or APP/APO (atactic polypropylene/polyolefin) plastic-body modified bitumen on a polyester substrate. Features double-layer ethylene film, fine sand, or mineral surfacing on both sides.
High-Speed Rail Application:
A polymer-modified bitumen membrane with long-fiber polyester reinforcement and fine sand surfacing, engineered specifically for railway waterproofing systems.
