Easily create dry zones under raised decks.


Deckorators® Dexerdry® offers a revolutionary deck weatherproofing solution. It is a simple, easy-to-install system that enables deck builders and homeowners to create dry zones under raised decks and eliminate water issues from ground-level decks. Dexerdry makes it possible to add extra outdoor living space and storage areas, with the confidence that they will not be affected by precipitation from the above deck structure. Decks built with Dexerdry require 1/8” slope per foot of framing; pitched away from home, to allow for proper runoff.

The proprietary polymer extrusion is uniquely crafted to fit snugly within the slotted-edges of Deckorators composite decking, creating a water-tight seal between boards. Available in black 12-, 16- and 20-foot lengths.
