Retaining Wall Installers FAQs, answered by experts

Generally speaking, a retaining wall should be between 3 and 4 feet high, depending on variables such as the wall-building material, the purpose of the retaining wall, and more. If you want your retaining wall to be taller than 4 feet, check with your local building ordinance office for the maximum allotment. You may also need a special permit for retaining walls over 4 feet tall.

A retaining wall can only function as a fence if it’s high enough on all sides to prevent someone from accidentally falling into the pool. However, most retaining walls retain dirt, which means their purpose is not related to safety. There would need to be nothing on the other side of the wall for it to be considered a fence, but in that case, it wouldn’t retain anything and would cease to be a retaining wall.  

Generally, a railroad tie retaining wall consisting of a single line of ties should be between 3 and 4 feet tall—and the height often tops out at around 6 feet. You can go taller, but you may need additional footings and reinforcements, including a second layer of railroad ties to support the added weight of the soil it’s holding back.

They prevent soil erosion, add flat space, and enhance property aesthetics.

If you don’t backfill a retaining wall—either at all or adequately enough—the wall won’t drain well, and water will be able to pass through it. Poor drainage will lead to a warped wall or a buildup of hydrostatic pressure, which can eventually collapse your retaining wall. If you have particularly sloped land, consult a structural engineer to ensure your hardscaping is adding value to your home.
