A retaining wall is a structure that retains or holds soil behind it. It’s basically a damn. It ensures that the terrain of your property is intact and well cared for. Retaining walls are also an integral part of landscaping.
They can be made from concrete blocks, treated timbers, rocks or boulders, or poured concrete. They can all retain soil, but, there are benefits including easy use and there are set-backs like shorter life span, depending on which material that you choose.
