What Is a Retaining Wall?

A retaining wall is a structure devised to restrict soil to uncommon slopes. They are used to force soils between two distinctive elevations often in areas where landscape possessing adverse slopes or in areas where the landscape needs to be modified severely and engineered for more functional purposes like hillside gardening or pathways.

A retaining wall is a erection designed and built to resist the lateral compression of soil when there is an anticipated change in ground elevation that surpasses the angle of onsite soils.

Every retaining wall supports a segment of soil. The segment is described as the soil which increases beyond the breakdown level of the soil type present at the wall site, and can be analyzed once the sheer vein test and angle is known. As the setback of the wall increases, the size of the slipping segment is reduced. This reduction lowers the heaviness on the retaining wall.

The most essential consideration in correct design and installation of retaining walls is to identify and neutralize the inclination of the retained material to move downslope due to gravity. This generates lateral soil pressure behind the wall which hangs on the angle of inner friction and the solid strength of the retained solid, as well as the direction and importance of movement the retaining structure experiences.

Lateral soil pressures are nil at the top of the wall. Soil pressures will push the wall forward or upset it if not accurately addressed. Also, any laying water behind the wall that is not drained by a drainage system causes hydrostatic force on the wall. The total force or load may be presumed to act at one-third from the deepest depth for laterally stretching from uniform height.

If the wall is meant to retain water, It is imperative to have proper drainage behind the wall in order to minimize the pressure to the wall’s purpose value. Drainage materials will diminish or eliminate the hydrostatic pressure and increase the stability of the soil behind the wall.
