Retaining Wall Installers FAQs, answered by experts

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.

Costs depend on material type, labor rates, and additional features like decorative finishes or reinforcement.

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.

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. 

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