Retaining Wall Installers questions, answered by experts

If you don’t backfill a retaining wall—either at all or adequately enough—the wall won’t drain well, and water will be able to pass through it. Poor drainage will lead to a warped wall or a buildup of hydrostatic pressure, which can eventually collapse your retaining wall. If you have particularly sloped land, consult a structural engineer to ensure your hardscaping is adding value to your home.

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.

Even if you think you know how to build a retaining wall theoretically, doing the actual work is a completely different story. There are lots of nuances in building retaining walls, and the slightest oversight can compromise their integrity. Therefore, we recommend you hire a pro to build, repair, or replace retaining walls.
