CCW MiraDRI 860-ULT is a self-adhering sheet membrane consisting of rubberized asphalt laminated to 4 mils (0.1 mm) of polyethylene to form a minimum 60-mil (1.5 mm) membrane. It is suitable for installations where the ambient temperature is between 15 °F (-9.4 °C) and 60 °F (15.6 °C). The combination of these two excellent waterproofing materials provides a high-performance, extremely durable waterproofing barrier. MiraDRI 860-ULT is used for vertical and horizontal waterproofing on structural foundation walls and decks. Below-grade tunnels, foundation walls, split slabs, plaza decks and parking decks are all areas where MiraDRI 860-ULT may be applied. It also may be used in interior areas such as mechanical rooms, laboratories, kitchens and bathrooms. MiraDRI 860-ULT should be covered with either CCW 200V/300HV Protection Course, CCW Protection Board, or CCW MiraDRAIN® drainage composites.
