Our line of APP modified bitumen membranes are among the industry’s best. They are proven to provide years of waterproofing protection in even the most extreme weather conditions and are versatile enough to be used in various applications.
Simply put, materials and quality manufacturing matter. We use only the highest quality asphalt and reinforced polyester fabric and chemically bond the two using a process that ensures the strength, flexibility and elasticity necessary to provide the long-term protection.
APS-4T is a highly versatile waterproofing membrane that can be used in roofing applications, but is also suitable for use on road structures and bridges, water reservoirs, basements, and multi-story parking garages among other applications.
