We have gone to contract for the finish carpentry portion of the project and are hopefully working out the final details of the 5th level exterior deck scope today. I appreciate the clarity you have provided thus far, I wish everyone could be so detailed!

Innovative Waterproof Decking System

HDG is proud to offer builders, architects, and homeowners an innovative waterproof decking system. The DuxxBak™ water shedding system directs water toward the edge of the deck, in the direction of the designed slope. This keeps the living area or storage area beneath the decking surface completely dry. Best of all, this engineered capability is built into DuxxBak composite decking so a water tight installation doesn’t require the installation of a secondary underdeck or internal drainage system made up of troughs and gutters. Installing the DuxxBak waterproof decking system expands the living area without the problems of moisture buildup common to other underdeck drainage systems.

What is DuxxBak and How Does it Work?

DuxxBak has dimensionally realistic wood grain yet contains no wood. Made of a Biodac®, rice hulls, polyethylene resins, and other high quality ingredients it has very minimal water absorption compared to wood-composite and PVC decking products. DuxxBak wood-free composite decking is engineered to be watertight. The unique interlocking design keeps water from leaking through the deck. Instead, Water travels through the Duxxbak™ channels and exits at the end of the deck.

Create Additional Living Space
with DuxxBak Waterproof Decking

Install DuxxBak waterproof decking on a 2nd level deck and the space underneath becomes usable as extended outdoor living space or storage. When the rain moves in promising to soak outdoor activities, those activities can move under deck and continue. Outdoor furniture, vehicles, and other equipment can safely be stored under the deck no matter the weather.

Applications for a waterproof decking system include covered patios, sundecks, roof top decks, boathouse sundecks and when you want to protect the substructure or what lies below. A water shedding deck provides usable space in any kind of weather.

Frequent Questions About DuxxBak Waterproof Decking

If you have questions about DuxxBack waterproof decking beyond what is shown here, please contact us.

Can we get samples?

A: We can provide samples upon confirmation of budget pricing.

Do we need to purchase this material from you directly? Where is a dealer in my location? Where can we buy locally in my location?

A: We are a certified dealer and can provide shipping estimates to any location.

My existing joists are running perpendicular, so I want to run the DuxxBak parallel to the home, is that possible?

A: DuxxBak is designed to run perpendicular to the home, as it requires an unrestricted minimum pitch of 1/8” per foot in the direction of intended water flow (along the length of the deck board). If existing joists are running perpendicular, cross-bracing can be added in order to create joists that are parallel.

Can you deliver to Canada? Handle customs?

A: Yes.

Can you deliver to Australia?

A: Yes. We can provide delivery to the US West Coast port of export, where you can arrange international shipping from, or you can provide us with the nearest Ocean Port in Australia, and we can handle the shipping.

What temperatures can DuxxBak withstand? Expansion in heat, can it handle snow/ice, etc.?

A: The deck boards have been reviewed for the temperature range of -20 to 125 °F.

I'm a contractor, can you send me samples in all colors so I can show my clients?

A: We are happy to send samples once we’ve confirmed that shipping prices to your region are acceptable. We can put together a mock shipping quote for a deck size typically installed by your company.

Can DuxxBak be laid on a plywood base?

A: DuxxBak requires 1.5″ of ventilation under the boards, so it should not be installed directly on a plywood base.

Stacked Deck Multifamily Example

The finished product not only looks exceptional, but the added bonus of a completely dry, weather-protected area beneath makes DuxxBak a real bargain when compared to many of its contemporary composite competitors. That reasonable cost and added functionality, when combined with a transferable lifetime warranty help the product really set itself apart from its peers.
