Bituthene is ideal for waterproofing concrete decks where in-service temperatures will not exceed 130°F (54°C). It can be applied to split slab construction such as in plaza areas and parking decks. Interior uses may include mechanical rooms, laboratories, kitchens and bathrooms. (For below grade applications,see “Below Grade Waterproofing Bituthene System 4000.”)
Bituthene is 1 /16 in.(1.5 mm)thick, 3 ft(0.9 m) wide and 66.7 ft (20 m) long and is supplied in rolls. It is unrolled adhesive side down onto concrete slabs primed with System 4000 Surface Conditioner. Continuity is achieved by overlapping a minimum 2 in. (50 mm) and firmly rolling the joint.
Bituthene is extremely flexible. It is capable of bridging shrinkage cracks in the concrete and will accommodate minor differential movement throughout the service life of the structure.
