It is constructed of reinforced portland cement hellip.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
Recommended stem designs for reinforced cantilever retaining walls with no surcharge are contained in tables 1 and 2 for allowable stress design and strength design respectively.
These design methods are discussed in detail in allowable stress design of concrete masonry tek 14 7a and strength design of concrete masonry tek 14 4a refs.
A slender section can be used in this retaining wall the tensile stresses within the stem and the base is resisted by steel reinforcement.
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.

Reinforced concrete cantilever types of retaining wall are recommended for heights up to 7 m.
The cantilever retaining wall cantilever wall constructed of reinforced portland cement concrete pcc was the predominant type of rigid retaining wall used from about the 1920s to the 1970s earth slopes and earth retaining structures are used to maintain two different ground surface elevations.
It has much thinner stem and utilize the weight of the backfill soil to provide most of the resistance to sliding and overturning.
Cantilever retaining wall are usually of reinforced concrete and work on the principles of leverage.
Reinforced concrete walls cantilever retaining walls can be constructed entirely from reinforced concrete.
