DryJoist is not a waterproof decking product – it’s a structural deck drainage system. DryJoist provides the necessary structural support every 4” compared to traditional 12” or 16” o.c. for many different types and brands of deck boards whatever they may be - unlimited decking material options, patterns/designs is the same system that creates a dry area below the deck.

Up to date, builders wishing to provide waterproof decks have attached additional gutter systems to the underside of the frame exposes supporting beams to a moist environment, used contemporary deck boards such as aluminum modern style, or layered wooden joists with water resistant membranes time intensive & pricey. DryJoist’s structural design is a single system structural design creates 100% waterproof area below ie: waterproof deck joists that provides the necessary utility of traditional deck joists yet provides the freedom to build a truly custom deck surface that is both waterproof and independent from the constraints of wooden joist spans or waterproof ‘add-on’ substructures.

DryJoist can be installed by the professional deck builder or DIY homeowner to build, refurbish or remodel a multitude of outdoor structures such as a backyard deck, second story balcony, patio, porch, roof deck, pool deck, walkout carport or garage deck.

DryJoist is a simple and single system; it is the first to provide both structural support for the deck’s surface boards while creating a 100% dry living space below. Other applications include landscape architecture such as water harvesting, or even a deck cover for outdoor kitchens.
