Also known as dry deck, underdecking is a deck add-on for deck builders who would like to expand the usable outdoor space of a deck. With a drydeck system, you can add a patio, outdoor kitchen, lounge area, or simply a dry storage space to your deck's under-deck space.
Dexerdry® is an underdeck system that can be installed at the same time as your decking, and requires very little framing modification other than a sloped deck surface.
Dexerdry® has been manufactured specifically for use with most major brands of grooved decking, and can be installed with Cortex® hidden fasteners (recommended) or other standard face screw systems.
Now available in small and large rolls, Dexerdry® can be delivered to your door for installation on you or your customer's deck.
Pro Deck Supply stocks the Dexerdry profiles for Azek, Clubhouse, Deckorators, Fiberon, TimberTech, and Wolf decking, usually available for quick-ship.

Inside Out™ Underdeck
Inside Out™ is an aluminum-titanium alloy panel system that can be mounted below deck framing on a new or existing deck, with a carrier channel system for easy install and removal.
RainEscape® is a membrane layer installed between the decking and framing which gives you the flexibility of choosing your under-deck space's ceiling, like a tongue and groove cedar or PVC.
DrySpace is a under-frame mount drainage system that can be installed during or after a frame is built. Dryspace is a great option if water drainage is the primary goal, but it will also create a semi-finished appearance to the underside of the deck.
