Waterproofing membranes that can resist to harsh environmental conditions is a key benefit. Waterproofing membranes based on Polyurethane (PU) offers outstanding advantages. It can resist to harsh environmental conditions such as extreme humidity and temperatures. Superior durable PU materials are a must-have for this type of application! Polyurethane-based with UBE Eternacoll® Polycarbonate Diol is the ideal material for waterproofing membranes. It provides an improved durability to PU thanks to excellent resistance to hydrolysis and extreme temperatures, as well as improved mechanical properties. As a consequence, this superior durability reduces the overall maintenance costs of PU waterproofing membrane!
