The DryJoistEZ Deck Drainage System allows builders to create completely dry space below decks and balconies, with a finished bead-board under-deck ceiling.

The patented design of DryJoistEZ gives builders and architects the freedom to build a truly customized deck or balcony space that is both waterproof and unmatched in fundamental strength. DryJoistEZ has the structural capability to span up to 6 feet between beams, which ​eliminates the need for traditional deck joists. This aluminum deck drainage system eliminates the need for multiple steps when waterproofing exterior balconies and decks. Gone are the days of built-up rubber membrane systems or poured-concrete balconies. Developers can add structure, waterproofing, and durability to balcony or deck spaces in one step.

DryJoistEZ is manufactured from marine-grade aluminum, which means that it has excellent weathering characteristics and protects your deck structure components from the elements. The DryJoistEZ Deck Drainage System is also fire-resistant, which makes it ideal for high-risk fire zones and multifamily applications.
