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.

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.

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.

Yes, to build a retaining wall, a permit is required. Similarly, any repairs or modifications to an existing retaining wall require permits. If the planned wall measures higher than 4 feet, most municipalities require designs and permits come through a licensed engineer. In some locations, if the wall is shorter than 4 feet, a permit may not be required. For the requirements in your area, contact your local government.

Most railroad tie retaining walls have a life span of 20 to 30 years, though you may need to replace your wall sooner if it’s repeatedly exposed to heavy rain, runoff, and excess moisture. Railroad ties are typically treated with creosote, which makes them much more durable than untreated wood. Though they last longer, they don’t last forever. For the most longevity, make sure your retaining wall has a sturdy base and steel reinforcements. You should also install drainage to direct water away from the wall.
