AridDek® Waterproof Aluminum Decking System

Meet AridDek: An All-In-One Deck Surface and Deck Drainage System

AridDek Waterproof Aluminum Decking does double-duty as an all-in-one deck surface and deck drainage system. Additionally, AridDek features an integrated gutter system for a usable, dry under deck area. Homeowners love AridDek because its safe, non-skid surface stays cooler to the touch than wood, composites, or concrete.

Manufactured from extruded 6005 T-5 marine-grade aluminum, AridDek is available in lengths up 36 feet. Deck boards fit together in a tight, tongue and groove configuration, forcing most of the water to run off the surface. Any water that gets through the tongue and groove is funneled into the integrated gutter channel, creating a 100% watertight decking surface.

From freezing rain and heavy snow loads to extreme heat and torrential downpours, with heavy traffic or just the everyday wear and tear caused by a busy family, the AridDek waterproof deck system is designed to out-perform conventional deck building materials.



Artisan Clay

Low Maintenance

Especially when compared to traditional deck boards, the marine-grade aluminum and powder coated finish of your AridDek Waterproof Deck System never need to be stained, painted, or sealed. AridDek requires no upkeep outside of periodic cleaning with soap and water.

Heat Regulating

Heat-Regulating: Stays cooler to the touch than traditional decking materials: aluminum rapidly dissipates heat, which keeps AridDek’s surface cooler to the touch than commonly-used decking surfaces.


AridDek’s unique aluminum decking design creates a 100% dry space beneath your waterproff deck, increasing usable space in your outdoor area.


Eco-Friendly: AridDek is 100% recyclable, and is made from up to 50% recycled scrap metal. While most building materials will eventually end up in a landfill one day, AridDek can be separated and recycled again.
