Abstract: The present invention features a drainage and support mat used as a supporting and drainage surface beneath sods, plantings, gravel and roofs and decks of concrete. The mat is made of a high-impact plastic sheet such as polystyrene, PVC, PET, etc., and consists of evenly spaced, upwardly projecting, dimple-type protuberances.

To counteract this, each of the protuberances of the mat has a slotted section in or adjacent to it. The slotted section crosses the flattened, truncated portion of the dimples, allowing any accumulating water to run off and down the sides of the protuberance.
