SeaBrick is a sustainable construction material developed by Kelp Island Inc. using seaweed fiber composites, or kelp, to create buoyant, interlocking bricks. The product is intended as a lower-carbon alternative to concrete and steel, offering claimed strength, water resistance, durability, ease of manufacture, and carbon sequestration for marine and land-based construction. The organization is raising funds to complete material and structural testing, conduct marine field trials, expand adoption, obtain regulatory approvals, and build kelp farms and production facilities.
