rust wedge

festival pavilion

A major issue in the preservation of historically significant waterfront buildings, spalling occurs when water enters cracks on a masonry structure and oxidizes underlying steel reinforcing material. Rust Wedge illustrates the expansive force of rusting steel by placing a piece of iron in the cleft of a block of concrete near the foot of the Festival Pavilion, allowing the ensuing rust to slowly fracture the block over time.
