Keep Things Dry Under a Deck
Friday, May 27th, 2011If you ever want to add storage or a patio under a deck, you’ll need a means of keeping the area dry. There are numerous under-deck drainage systems available that can accomplish this goal. Some have to be professionally installed, while others, especially the ones meant to retrofit an existing deck, can be easily installed by any competent DIYer.

There are some differences in the systems, but all work on pretty much the same principle (Illustration, above). They consist of “troughs” that get installed under or in between the deck joists. As water runs through the deck boards, it collects in these troughs, which are tilted toward the outside of the deck. Then the water flows into a gutter-like system that directs the water to a downspout.
