Retaining Wall Installers questions, answered by experts

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.

Rebar is a steel support that goes inside concrete to prevent structural damage over time. Concrete is susceptible to impact, weight, and tension. By inserting rebar into the concrete during the installation, you can help extend its lifespan and avoid hazardous situations where the foundation of your home gives way to tensile forces.

Most retaining wall installations can be finished in one to three weeks, but the timeline varies based on factors like wall size and material. The local climate and major weather events, such as storms or flooding, can also extend the project's timeline, as can any holds ups in the permitting process.

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.
