An Under Deck Drainage System, also called an Under Deck Ceiling, is like a dropped-ceiling underneath your second story deck. The ceiling actually collects the rain water that would normally fall between the deck boards, and moves it into a rain gutter and away from your deck. Under Deck Oasis does more than just divert water away from your deck space, it also finishes and beautifies the space below your deck. Why spend so much time and money on your home and then leave this valuable area unfinished? Under Deck Oasis panels come in multiple colors and finishes. Wood grain finishes give a realistic appearance of wood for that natural look and feel, while the solid matte panels give a clean and modern look at a lower price. Smooth and Rustic finish options provide even more customization.
