Trex RainEscape is an above-joist deck drainage system designed to capture rainwater before it reaches the area beneath your deck. By directing water into troughs, gutters, and downspouts, it keeps the space below dry and protects your deck’s framing from long-term moisture damage.
Trex RainEscape is installed on top of the deck joists and beneath the deck boards. It uses a network of drainage troughs and downspouts to collect rainwater and channel it away from the deck structure. This innovative design helps create a dry, usable area beneath elevated decks while protecting the framing from water exposure.
Trex RainEscape is primarily designed for new deck construction because it is installed above the joists before the decking boards are attached. In some cases, it can be added to an existing deck if the deck boards are removed during a renovation or replacement project. Our team can evaluate your deck and recommend the best solution.
