Retaining walls and sitting walls can provide both beauty and functionality. Consider the benefits of a retaining wall. Not only do they hold back a slope that may erode over time, they also serve as an attractive feature. Selecting proper, quality materials and installing according to code, with a strong base and solid design, make all the difference in the outcome. The final product can be a dramatic focal point that provides a background for plantings or act as a border for landscaping.
