DryJoistEZ® Deck Drainage System

DryJoistEZ is a drainage system that creates dry space below decks and balconies, with a finished bead-board ceiling below.

DryJoistEZ eliminates the need for multiple steps when waterproofing exterior balconies and decks. Gone are the days of built-up rubber membrane systems or lightweight poured concrete balconies. Developers can add structure, waterproofing, and durability to balcony or deck spaces in one step.
