CCW-711-90 Sheet Membrane and Flashing is a composite consisting of a self-adhering rubberized asphalt membrane laminated to a high-strength, heat-resistant woven polypropylene mesh. A siliconized release liner prevents the material from sticking in the roll, and is easily removed for installation. CCW-711-90 Sheet Membrane and Flashing is primarily designed to be used in conjunction with CCW-500 Hot-Applied Membrane. It may be used as a preformed first course on difficult-to-coat substrates such as lightweight structural concrete. As a flashing, it provides a reinforced, uniform layer on vertical surfaces while reinforcing cracks and joints. The woven mesh is designed to withstand high temperatures, allowing the membrane to become an integral part of the CCW-500R Hot-Applied and Vapor-Lock Waterproofing Systems. The factory-controlled quality ensures uniform thickness on the job, while the inherent waterproofing properties of the rubberized asphalt membrane provide an excellent water barrier.
