Expansion joint systems form a continuous uninterrupted waterproofing solution from the start of the expansion joint to its termination. Expansion joints are commonly found in, above, or below grade building walls or on the roof. The joint system will act as both the expansion joint and waterproofing. The flat profile of the expansion joint does not obstruct the flow of water to drains. The system can be installed on a wide variety of substrates including concrete, wood, metal or even plastic. The flat expansion joint end termination accommodates movement in all three directions and there is no warping, curling or wrinkling. Any seaming is as flexible and has the same elongation as the base expansion joint material itself.
