Trex® RainEscape® Products
One Deck. Two Usable Spaces.
Trex® RainEscape® is an under-deck drainage system that catches rain, spills and snow melt before they drip through your deck boards. The result is a dry, usable space under your deck. The system is built from a few simple parts that work together. Explore each one below, then talk to our team or find an installer to plan your project.
-
Trex® RainEscape® Trough
The layer that catches the rain. A rolled polyethylene sheet that sits on your deck joists, under the deck boards, and carries water to the downspouts. 19-5/8" wide, in 12' and 16' lengths.
-
Trex® RainEscape® Downspouts
Where the trough meets the gutter. A molded piece that collects water from the trough and hands it off to your gutter. Fits joists 12" or 16" on center.
-
Trex® RainEscape® Wall Flash
A soft seal where the deck meets the house. A self-adhesive EPDM foam strip that sticks to the first deck board along the house and compresses against the wall to seal. 25' roll, black.
-
Trex® RainEscape® 4×4 Post Flash
Seals the trough around railing posts. A molded black skirt that slides down over a 4x4 post and is sealed to the trough with butyl caulk and tape.
-
Trex® RainEscape® 4″ Tape
The tape made for the system. Single-sided butyl tape, 4" wide on a 50' roll, for sealing trough seams and securing downspouts and flashing.
-
Trex® RainEscape® Soffit Light
Directional LED soffit lights for the ceiling under your deck. Two steel spring clips hold each light in place. Black, bronze or white. Requires an installation kit or compatible transformer, sold separately.
How the parts work together
- Water passes through the gaps between deck boards.
- The trough catches it and carries it along.
- Downspouts send it out to the gutter.
- Flashing and tape seal the edges, posts and seams.
