Do i need a retaining wall?

Retaining walls are used to support soil and other materials that would otherwise collapse or erode, so whether or not you need a retaining wall depends on your specific circumstances.

You should consider the nature of the soil and the size and shape of the area you’re attempting to protect. If the slope is steep and soil is loose, a retaining wall may be necessary to safely hold back the soil. If the slope is relatively gentle and the soil is more solid, then a retaining wall might not be necessary. If you’re unsure, it’s always best to consult a structural engineer or landscape architect to assess the stability of your backyard.
