CCW Root-Barrier is a high-strength, specially formulated membrane designed for the CCW Green Roof and CCW-500R waterproofing Systems. It does not contain plasticizers that can migrate to the surface and attack some asphalt-based materials. Root-Barrier is made from a layer of tightly-woven HDPE scrim with a polymeric coating on both sides. Root-Barrier is used in planter, CCW-500R System and Green Roof applications to prevent root migration into the waterproofing system.
