CCW 711-90 Sheet Membrane and Flashing is a 90-mil-thick 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 to 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 90-mil layer on vertical surfaces while reinforcing cracks and joints.
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. 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-LockWaterproofing Systems. When used as a first course, this reinforced membrane provides a uniform, pinhole-free layer, providing an excellent substrate for the monolithic hot-applied layer. As a flashing for the CCW-500R System, the membrane combines the strength of the woven mesh with the self-adhering and elastomeric properties of the rubberized asphalt. This combination provides durable, reinforced flashing.
- Adheres tenaciously to the primed substrate while the CCW-500 Hot-Applied Membrane bonds with the mesh, ensuring a waterproof condition
- Its inherent durability and heat-resistant properties ensure the integrity of the membrane when the CCW-500 Hot-Applied Membrane is installed over it.
