However, if you plan on using gravel in the base, it is important to use a high quality aggregate or block to reduce the stress on the structure. If using gravel, do not settle it to the bottom or surface of the retaining wall.

The majority of builders use a four to six foot retaining wall system with gravel on the bottom to provide additional footing. In addition, if the retaining wall system has a lip at the top, the cost per square foot decreases to nearly zero. The lip adds additional stability to the retaining wall.

Once you determine the number of retaining wall blocks needed, it is time to decide what material to use. In general, concrete is used to construct most retaining wall blocks. However, there are several different options that allow you to choose the right color, texture and amount of “give” to your yard.
