Also known as bulkheads, these walls are vertical structures that provide resistance from waves to prevent erosion.
More About Sea Walls
Cracks, expansion joints, and construction joints allow water to penetrate behind the wall eroding the soils. Injecting polyurethane behind the bulkhead can seal the cracks and joints. Using a two-part closed cell polyurethane that displaces water will fill the voids and seal the leaking walls. Prevention of water intrusion is important to extend the life of the seawall and retained area.
