What is Trex RainEscape and How Does It Work?

Trex RainEscape is a drainage system for your deck. The system sits over the joists creating a trough that sends water into the downspout, which then funnels the water into the gutters. Trex RainEscape is made with rugged plastic and ultraviolet inhibitors, providing durability to withstand any extreme weather. It’s also easy to install, requiring only scissors or a utility knife, staple gun, and caulking gun with most installations completed in one to two hours.
Freezing temperatures and snow won’t affect the drainage system. Water and snow simply run through the trough and drain out the downspout. Most debris stays on the deck boards and won’t fall through the gaps between boards. Any small debris that does enter the system is easily flushed out with a quick deck wash or heavy rain.

What is Trex RainEscape made of?
Trex RainEscape is made from rugged plastic with ultraviolet (UV) inhibitors. The UV inhibitors protect the system from sun damage, preventing deterioration over time and ensuring long term performance in all weather conditions including intense heat, freezing temperatures, and heavy rain.
Can Trex RainEscape be installed on existing deck?
Yes, Trex RainEscape can be installed on an existing deck, however the deck boards must be removed to access the joists before installation. Since RainEscape sits over the joists beneath the deck boards, retrofitting an existing deck requires more labor than installing during a new deck build. A certified Trex installer can assess your existing deck and determine the best approach for your specific situation.
Does decking have to be sloped for Trex RainEscape?
Yes, a slight slope is recommended for proper drainage. Trex recommends a minimum slope of 1/8 inch per foot away from the house to ensure water flows efficiently through the trough system and out the downspout. Without adequate slope, water may pool in the troughs rather than draining properly. A certified Trex installer will ensure your deck is built or adjusted to the correct slope before installation.
