DECK-O-DRAIN drainage system provides an effective drainage system for concrete pool decks. Wherever specified, the system effectively collects and carries water away quickly from pool decks and other patio areas. Made of tough, long lasting PVC, the DECK-O-DRAIN system resists wear and is non-corrosive. Both the deck and subgrade receive watertight protection. The unique non-directional design of DECK-O-DRAIN eliminates the need for right or left fittings. One attachment can be used for both by simply facing it in the direction needed. A flat contour profile allows a tight fit against any wall DECK-O-DRAIN drainage system installs easily. There are no trenches to dig or deep excavations to make. DECK-O-DRAIN can be used as a screed rail in final flatwork preparation.
