The CCW MiraDRI 861 is a self-adhering sheet membrane consisting of rubberized asphalt laminated of polyethylene to form a minimum membrane. The combination of these two excellent waterproofing materials provides a high-performance, extremely durable waterproofing barrier. MiraDRI 861 is suitable for installations where the ambient temperature is 40 °F (4.4 °C) or above. MiraDRI 861-861 can be used for applications between 25 °F (-3.9 °C) and 40 °F (4.4 °C) if the product is stored in a heated area until use and the laps are treated with CCW contact adhesive. MiraDRI 861 membrane is used for vertical and horizontal waterproofing on structural foundation walls and decks. Below-grade foundation walls, tunnels, split slabs, plaza decks and parking decks are all areas where MiraDRI 861 may be applied. MiraDRI 861 also may be used in interior areas such as mechanical rooms, laboratories, kitchens and bathrooms. MiraDRI 861 should be covered with either CCW 200V/300HV Protection Course, CCW Protection Board, or CCW MiraDRAIN® drainage composites.
