Trex RainEscape is an under-deck drainage system that uses a network of troughs and gutters to keep rain, spills and snow melt from dripping through elevated deck boards creating a dry space below the deck. Once the Trex RainEscape deck drainage system is installed, homeowners can design an outdoor living space that includes lights, ceiling fans, an entertainment center, an outdoor kitchen and more. Or, the dry, useable space below the deck can be used for much needed storage.
