What is the purpose of retaining walls in residential construction?

Retaining walls serve a crucial function in residential construction, primarily designed to hold back soil and prevent erosion. When a property features changes in elevation, such as slopes or hills, retaining walls are utilized to create level areas by countering the lateral pressure of the soil. This helps maintain the stability of the landscaping and prevents soil displacement that can occur due to rain or gravity.

The presence of a retaining wall can effectively manage water runoff and reduce the risk of erosion, which could otherwise lead to significant structural challenges or damage to both the property and surrounding areas. By controlling the movement of soil, retaining walls provide structural support and enhance the safety of the landscape.

While some retaining walls may also contribute to aesthetic appeal or delineate property boundaries, their primary function is to support soil stability, ensuring that the landscape remains intact and functional over time.
