Retaining Walls Retaining walls look like simple stacked stone but they are actually carefully engineered systems that fight the never-ending war with nature. Retaining walls are perfect for sloped landscapes where runoff can cause hillside erosion. Other ideal locations for a retaining wall include area downhill from soil fault lines and where the downhill side of a foundation is losing supporting soil or its uphill side is under pressure from sliding soil.
