DryJoist is a structural deck drainage system, meaning the deck’s surface is supported by the same system that creates a dry space in the area below. Traditionally, joists are repeated structural members used to build a supporting frame, ultimately determining the design, strength, and material selection for the deck’s surface. DryJoist has the necessary utility of traditional deck joists yet provides the freedom to build a truly custom deck surface that is both waterproof and unmatched in structural strength.
DryJoist is the first to provide structural supports for the deck’s surface boards while creating a 100% dry outdoor living space in a single deck system.
