Overview
The trough is the heart of the Trex® RainEscape® system. It’s a rolled sheet of tough polyethylene that sits on top of your deck joists, under the deck boards. Rain, spills and snow melt pass through the gaps in your decking, land on the trough, and flow to the downspouts and out to your gutter. That keeps the space below dry, so one deck gives you two usable spaces.
Good to know
- The trough is not a structural surface. It can’t support body weight, so it’s installed under the deck boards, never as a walking surface.
- Debris rarely gets in, because anything that reaches the trough has to be small enough to pass between the deck boards. If some builds up, a standard washing or a hard rain usually clears it, and the 2×4 access panel is there for the rare case.
- Always install to the Trex® RainEscape® installation guide. A Trex Certified or experienced installer can help.

Questions & answers
Frequently asked questions
- How wide is the Trex RainEscape trough?
The trough is 19-5/8" (49.8 cm) wide, nominal, and comes in 12' and 16' lengths.
- Can I install it over an existing deck?
Yes, although it's ideally installed during new construction. You'll need to remove the existing deck boards to put the system in.
- How do I clean out debris?
Very little gets in, because it has to be small enough to pass through the decking. Regular deck maintenance prevents most build-up. In the rare case there is some, use the 2x4 access panel.
