The unique Trex RainEscape under-deck drainage system keeps rain, spills, and snowmelt from dripping through the decking boards above, creating a dry area below for you to enjoy more indoor living space, outdoors. Homeowners can design an outdoor living space below their deck that can safely include lighting, ceiling fans, an entertainment center, kitchen and more. Not only does this product keep you dry below, but it keeps your framing dry which will extend the life of your deck for years to come.
