"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

The longevity of flood walls depends on how they were constructed, but most wood, gravel, and cement flood walls last 10 years. While aluminum flood walls may cost far more initially, they can be a good investment as they can last decades and will not be damaged by exposure to the elements.

Small retaining walls still require a foundation of some kind, typically a concrete footing. This helps to ensure the wall is structurally sound and prevents the ground from shifting over time, especially during those winter freeze/thaw cycles. The footing helps spread the weight of the wall and the load it carries over a larger area of the ground, thus assisting with stability. This is true of small retaining walls, larger rock garden walls, and the like. 

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.

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.

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.
