What is the purpose of a timber retaining wall deadman?

A timber retaining wall deadman is used in order to help support the retaining wall. It is placed a couple of feet behind the wall, where the soils is most likely to fail or give way. The deadman is buried and attached to the retaining wall via a cable or tie rod, in order to support the wall just in case it starts to fall. This gives you ample time to repair the wall before the soil totally pushes it down, destroying the barrier and division that it is providing. A timber retaining wall deadman can be placed at several points behind the wall, depending on its length and need.
