Dexerdry is the patented above floor joist flange gutter placed between deck board which prevents water and the elements from penetrating the surface of the deck. In other words, Dexerdry provides virtual dry space under any outside deck.

The Deck Drainage System transforms the area under decks into dry, all-weather leisure or storage space without major renovation.

Ideal for second-story decks, TimberTech’s DrySpace under deck drainage system collects and channels moisture from the spaces between your planks.

Escape the elements and expand your outdoor living space by using Trex's RainEscape deck drainage system.

Trex RainEscape's trough and downspout design drains water from the deck above allowing the area below to be dry and suitable for additional outdoor living space.
