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 doesn't require any special framing configurations 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.
Dexerdry® for Azek® and TimberTech® decking is available for quick delivery.
Dexerdry® for Fiberon®, MoistureShield®, Trex®, EverGrain®, and Deckorators® grooved decking are only available for special order at this time.

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.
The DuxxBak® decking system is a water-diverting, interlocking deck board system that keeps water out of your under-deck area by channel water via the interlocked channels in the deck boards. This gets your underdeck and decking system installed all in one easy process.
