Finding a cost effective solution for how to waterproof a deck in order to provide a usable outdoor living space underneath has long been an often expensive problem. Traditionally – Vinyl Decking has been the solution, but what if you want a more attractive product on your decking surface, like Exotic Hardwood or Composites like Trex? Well – we now have a solution for that, with an innovative product called Trex Rain Escape.
This easy to use system consists of a series of roll-out troughs that create water channels down each joist run to an adjustable downspout which has been designed to work with a variety of joist depths and standard guttering systems.

We’ve also included a PDF Installation guide below – which is available for download here.
