DuxxBak Waterproof Deck Builder
A composite deck on top and a dry, usable space below. DuxxBak boards interlock to shed water off the surface.
Built by DreamDecksWhat Is DuxxBak?
DuxxBak is a composite decking system with boards that interlock to create a watertight surface, so rain runs off the deck instead of through it.
That makes it ideal for elevated decks with a patio, storage, or hangout space underneath. We have installed DuxxBak on homes and on a commercial multi level pool deck in North Royalton.

Frequently Asked Questions
Is DuxxBak really waterproof?
The interlocking boards are designed to shed water off the surface and into a gutter, keeping the space below dry in normal rain.
How does DuxxBak compare to an under deck ceiling?
DuxxBak keeps water off at the surface. An under deck ceiling catches water below the joists. Both create dry space; we help you choose.
Can DuxxBak be used around pools?
Yes. We installed it on a commercial pool deck for Liquid Lifestyles in North Royalton.
Does DuxxBak need special framing?
It needs a slight slope for drainage, which we build into the framing.
Is DuxxBak more expensive?
It usually costs more than standard composite, but it can replace the cost of a separate under deck ceiling.
