What Is Retaining Wall?

A wall is constructed at the edge of the excavation to retain the amount of earth or similar clay, which is designed to resist pressure on the ground side, which are called retaining walls.

A retaining wall is used for a specific purpose when there is a desired change in the elevation of the ground.

A basement wall is one type of retaining wall. In some cases, the retaining wall is made to resist the side pressures generated by the water pressure.

Uses of Retaining Wall

  1. A retaining wall is mainly used to prevent soil erosion. It protects your property in sloping areas.
  2. Heavy rains cause extensive property damage. The use of retaining walls in flooded areas can prevent flooding/erosion during heavy rains.
  3. If the house is located on a platform that is higher than the surrounding land, there is a risk of damage to the building due to the soil sliding slowly. Secure the building using a retaining wall.
