If the soil around a downhill foundation is washing away, or erosion from a slope is compacting an uphill foundation, a retaining wall can help.

Does a 2 foot retaining wall need drainage?

Is it hard to build a retaining wall?

Building a retaining wall is a straightforward project that offers many benefits and landscaping opportunities. This guide will teach you how to build a retaining wall with concrete blocks.
