Retaining Wall Installers questions, answered by experts

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.

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.  

The lifespan of a retaining wall varies based on its particular material, whether it was properly installed, how well it’s maintained, and your local climate. Concrete, stone, and brick retaining walls last the longest, with concrete lasting between 50 and 100 years on average. Brick tends to last the longest, with a minimum of one century, under the right conditions. 

Timber retaining walls can start to deteriorate at 20 years, depending on the wood quality, but in the best case, they can last 40 years. Pressure-treated wood retaining walls last 30 years on average.

Through proper drainage solutions and compacting the foundation soil.

Railroad ties can be good for retaining walls, but it depends on the area. They have a desirable rustic look and are durable. The problem is they’re treated with creosote, a preservative the EPA says poses a risk to humans and wildlife. Over time, the preservative seeps out of the wood and into the ground. Many areas have banned the use of creosote-treated wood on residential properties. If your area does allow it, never use railroad ties near an edible garden or drinking water source. Instead, use wood that’s treated with an EPA-approved preservative or a wood-alternative composite material.
