Aquastop Extraflex

Aquastop Extraflex is a premium cold-applied, cold-cured polyurethane waterproofing membrane designed to deliver long-lasting protection for large surfaces. Formulated with elastomeric hydrophobic polyurethane resins, it cures by reacting with moisture in the air and substrate to create a seamless, highly flexible waterproof barrier. Its superior crack-bridging capability, excellent adhesion, and outstanding resistance to water, chemicals, UV exposure, and temperature variations ensure reliable performance in demanding environments. The monolithic membrane eliminates joints, laps, and seams, reducing the risk of leakage. Suitable for both internal and external applications, Aquastop Extraflex is ideal for residential, commercial, and industrial waterproofing projects.
