Under Deck Drainage

Under deck drainage turns the space below an elevated deck into dry, usable room, and keeps the framing out of the weather while it is at it.

There are two kinds and they are not interchangeable. Above-joist systems sit beneath the deck boards and shield the whole frame, but the boards must be off to fit one. Below-joist ceilings retrofit to a finished deck and leave the frame above them wet. We stock the above-joist type.
