"Extremely pleased with how helpful and easy this group was to work with. I’m active duty and stationed outside of the state, but this crew was on point in getting my grandfathers walkway installed. They were very quick to get someone out to quote the job and work is into their schedule. It looks great! I am very happy I could trust a company to do quality work and not have to be present to provide oversight. Huge stress relief! Highly recommend this group!"

Retaining Wall Installers questions, answered by experts

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.

With foundation walls, the slab on grade and force at the top of the wall is resisted by flooring. With retaining walls, the force at the top of the wall is not resisted.

The lifespan of a retaining wall varies based on its material, installation quality, maintenance, and local climate, with an average range of 20 to 100 years. Retaining walls made from durable materials like concrete, stone, and brick generally last a minimum of 50 years. Concrete walls typically last between 50 and 100 years, while brick can last for over a century in ideal conditions. Timber retaining walls can last from 20 to 40 years, depending on the wood quality, and pressure-treated wood walls average around 30 years. It is important to note that a retaining wall can fail prematurely if it was poorly constructed, for example, with inefficient footings or without necessary rebar reinforcements.

Sand and gravel are two suitable options for filling behind a retaining wall. If you’re building your own retaining wall, you’ll complete this part of the process—known as backfilling—after you finish laying the blocks. Make sure not to skip it—otherwise, you could wind up with drainage issues, which can cause your retaining wall to collapse.
