What is DekTek Tile? DekTek Tile is an elegant, new, and innovative precast concrete decking material that is especially designed for elevated decks. These 1" thick concrete deck pavers are light in weight and can be used on most standard wood-framed raised decks and roof decks The ultra thin DekTek tiles are engineered to span across 16" o.c. wood joists. DekTek Tiles are custom poured high strength concrete deck tiles that support more than 1,000 lbs per tile. The concrete deck pavers are designed to be the same thickness as standard decking products so they can be used in conjunction with wood or composite decking materials for accent borders or edge trims.
