Saint Gobain - Weberdry PUR Bitumen
weberdry PUR bitumen is a liquid-applied, permanent elastic, cold applied and cold curing, bitumen extended, single component solvent based polyurethane membrane used for long-lasting waterproofing.weberdry PUR bitumen is based on pure elastomeric hydrophobic polyurethane resins and is extended with chemically polymerized virgin bitumen, which results in excellent mechanical, chemical, thermal and natural element resistance properties. weberdry PUR bitumen cures by reaction with ground and air moisture.
