Sika Drainage Mat 720 4' x 50' per Roll

Sika Drainage Mat 720 consists of an impermeable high flow dimpled polypropylene drainage core heat-bonded to a layer of woven polypropylene filter fabric on the top side and a polyethylene membrane protection film on the bottom side. The filter fabric retains soil or sand particles as well as freshly placed concrete or grout, allowing filtered water to pass into the drainage core. Use the woven filter fabric with freshly placed concrete or grout.

• Variable flow and compressive strength configurations
• High crush resistant configurations for vehicular traffic
• Pre-assembled filtration and membrane protection layers
• Conformable to irregular surfaces
• Mildew and rot resistant

Application

Clean surface of loose debris and install Sika Drainage Mat directly on Sikalastic RoofPro and Sikalastic 320 NS/SL membrane with filter fabric side up and membrane protection layer down and in the direction of maximum slope. Attach mat to membrane surface with Sikaflex 11FC or approved adhesive as necessary to keep in position. At edge overlaps place adjacent panels so the cores abut and secure the fabric at 3–5' (0.9–1.5 m) intervals with Sikaflex 11FC or approved adhesive. At roll ends and abutments without overlaps peel back fabric and remove 4'' (10.2 cm) of core then secure overlap. All core joints and terminations must be covered by fabric overlay.
