Concrete masonry cantilever retaining walls if unrestrained a soil embankment will slump to its angle of repose.
Cantilever concrete retaining wall detail.
Some soils such as clays have cohesion that enables vertical and near vertical faces to remain partially intact but even these may slump under the softening influence of ground.
The base is divided into two parts the heel and toe.
Cantilever retaining wall is the most common type of earth retaining structure.
