Turn the space under your elevated composite deck into usable outdoor living with Trex RainEscape.
This over the joist drainage system installs before the deck boards go down. Flexible troughs catch every drop of rain, snowmelt, and spills that fall between the boards, then channel the water to downspouts and into your gutters. The result? A completely dry area below and full protection for the wood substructure.
Why it works so well with composite decking:
• Keeps joists, beams, and fasteners dry for decades
• Holds screws in place longer thanks to the sealed system
• Creates a true second outdoor room — add lighting, a ceiling fan, furniture, or storage
• Easy install (utility knife, staple gun, caulk gun)
• Backed by a 25-year warranty
No more drips. No more wasted space. Just a dry, protected deck that lasts as long as the composite boards on top.
Thinking about waterproofing your next elevated deck project? Happy to walk through how Trex RainEscape fits your design.
