A retaining wall is a structure that holds back enclosed material. Your retaining wall can be decorative, used to hold back gardening soil in the front of a home or a structure that is used for leveling steep or unwanted grades.
The most common reason to install a retaining wall is to level a slope on your property. This leveling process allows for areas that were once impractical to become level and more productive areas. For example, it could be for raising a garden bed or adding extra yard space strong enough to park vehicles on.
