SOPREMA’s flagship waterproofing system used over the years throughout North America and around the world has protected some of our most iconic structures including the George Washington Bridge in Ney York. The use of a 177 mil SBS modified bitumen membranes that is heat welded to the concrete deck and ready to accept asphalt paving provides many key benefits including superior adhesion to concrete decks to reduce blisters, consistent membrane thickness and a monolithic bond to asphalt pavement providing excellent shear stress resistance.
Hot rubber systems have been used throughout the years to provide an effective waterproofing system for bridge decks receiving an asphalt overlay. These systems are built-up in the field utilizing layers of rubberized asphalt and fleece reinforcement to achieve the specified membrane thickness. Benefits include a seamless application that can achieve various membrane thicknesses based on the number of layers.
SOPREMA offers both hot rubberized asphalt and cold liquid STPE solutions based on your project requirements. The benefits of liquid applied systems include achieving higher mil thicknesses for improved performance along with the flexibility to continuously waterproof intricate and irregular details. SOPREMA’s COLPHENE LM Barr utilizes STPE technology which is moisture tolerable, cures quickly and minimizes time to backfill.
