Retaining Wall

A retaining wall is a structure designed and constructed to resist the lateral pressure of soil or other materials when there is a desired change in ground elevation that exceeds the angle of repose of the soil. It serves to stabilize slopes and provide useful areas at different elevations by creating terraces on steep slopes. Retaining walls are made from a variety of materials including concrete blocks, poured concrete, treated timbers, rocks, or boulders. They can also include additional reinforcement, such as geogrids or tiebacks, for added stability. The design of a retaining wall must consider the ground conditions, the height of the wall, the type of soil, the surcharge loads it will bear, and the drainage conditions, to ensure that it functions effectively and prevents the downslope movement of soil, thus protecting structures and landscapes from potential damage. Proper installation and maintenance are crucial for the longevity and effectiveness of a retaining wall.
