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.

Rain Flow Total Gutter Protection is a system that fills the entire gutter opening so that nothing but water can get in.

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