Concrete retaining walls are a stabilising structure used to hold sloping ground in place and to prevent the erosion and movement of soil. A retaining wall must be substantial and sturdy in structure in order to accommodate and redistribute lateral pressure caused by sloping.
It is normally designed with seepage holes, which allow collected ground water to escape. This releases the additional pressure created by accumulated water and helps keep the retaining wall stable. Several different materials can be used to construct a retaining wall. Reinforced concrete is often used and can be especially designed for this purpose.
