What Is DuxxBak Decking?
What Is DuxxBak Decking? The Dry-Space Deck System Most Homeowners Don’t Know Exists
Most homeowners think of a deck as one thing:
A flat outdoor surface attached to the back of the house.
But if your home has a walk-out basement, a patio beneath the deck, or plans for a screened porch underneath, that “simple deck” suddenly becomes a problem.
Traditional decks leak.
Rainwater drips through the boards, down between the joists, and turns the space underneath into a damp, unusable mess.
That’s exactly the problem DuxxBak decking was designed to solve.
What Makes DuxxBak Different?
DuxxBak is a patented composite decking system that functions as both:
A high-quality deck surface
And a built-in waterproof drainage system
Unlike standard composite boards, DuxxBak planks are engineered with interlocking channels that capture water and direct it away from the home.
No under-deck ceiling.
No additional membranes.
No add-on systems.
The decking itself is the waterproofing.
The Big Idea: A Truly Dry Space Under Your Deck
With conventional decking, homeowners typically have three choices:
Live with water dripping through the deck
Add an expensive under-deck drainage system
Build a roofed structure instead of a deck
DuxxBak creates a fourth option:
A deck that keeps the space below completely dry by design.
That means the area under your deck can become:
A dry patio
An outdoor living room
A storage area
A screened porch
An outdoor kitchen
All without the cost and complexity of secondary drainage systems.
Built for Real-World Conditions
Here in Western Pennsylvania, decks face:
Heavy rain
Freeze/thaw cycles
Snow load
Humidity
Mold and mildew pressure
DuxxBak was engineered specifically to handle these conditions.
It is:
100% PVC composite
Non-organic (won’t rot)
Mold and mildew resistant

This isn’t just decking – it’s an exterior building product designed to perform like roofing.
Who Is DuxxBak For?
DuxxBak is ideal for homeowners who:
Want to use the space under their deck
Have a walk-out basement
Plan to add a patio beneath the deck
Want a cleaner, higher-end outdoor living area
Don’t want to deal with under-deck ceiling systems
If you’ve ever looked at the underside of a traditional deck after a rainstorm and thought:
“There has to be a better way…”
This is that better way.
