A retaining wall deadman is a crucial component in retaining wall systems, acting as an anchor to resist lateral earth pressure. It consists of galvanized steel tieback rods or cables embedded in the ground and attached to the retaining wall. The deadman is buried underground and provides a stable anchorage point, ensuring the stability and integrity of the retaining wall. Its proper design and installation by qualified engineers and contractors is essential for the safety and longevity of retaining wall structures.
