Retaining Wall Installers FAQs, answered by experts

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.

There are contractors specifically trained in the design and construction of retaining walls. Retaining wall contractors are skilled at dealing with the soil on your property and assessing what kind of drainage should be installed. They will recommend the best materials to use for the project and can handle the processing of permits by local authorities.

Each design is different, so we can’t say definitively if you’ll need a dedicated drainage system in place for a two-foot retaining wall. However, you can likely skip the drainage, as this project is typically served for walls that are 4 feet tall or more. Even with a relatively low wall, consider drainage if you are building on top of clay or poor-draining soil types or if there are buried water sources nearby, like a well used for other outdoor garden projects.

Costs range from $5,000 to $15,000, depending on size, material, and design complexity.

To maintain the integrity of your landscape, a retaining wall must be installed if the slope of the angle exceeds 35 degrees. The lean of the wall must be 1 inch per 12 inches in height to disperse the weight of the soil uniformly and guarantee the correct drainage of the soil.
