Royston Membranes

Royston Membranes products are used as waterproofing and reflective crack solutions for both transportation and commercial applications. Our installation process utilizes adhesives to provide superior bonding to the bridge deck, a flexible sealant at curbs and longitudinal membrane terminations to create superior waterproofing solutions.

Royston Membranes are manufactured using a reinforced laminate of impregnated woven fiberglass with a high strength inner core sandwiched between two layers of polymer modified bitumen. Royston Membranes feature a unique 3 inch leading edge that guarantees a positive compound-to-compound seal at every overlap.
