CCW-711-70 Waterproofing Membrane is a composition of a self-adhering rubberized asphalt membrane laminated to a strong, heat-resistant woven polypropylene mesh. A siliconized release liner prevents the material from sticking in the roll and is easily removed for installation. CCW-711-70 Pre-Pave Sheet Membrane Waterproofing System will protect cracking in the asphalt overlay while preventing structural damage from water and de-icing salts. Factory-controlled thickness ensures uniform thickness on the job, while the inherent waterproofing properties of the rubberized asphalt membrane create an excellent water barrier that makes this product ideal for use in Department of Transportation projects that require waterproofing membranes.
