Retaining Wall Installers FAQs, 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.

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.

Most railroad tie retaining walls have a life span of 20 to 30 years, though you may need to replace your wall sooner if it’s repeatedly exposed to heavy rain, runoff, and excess moisture. Railroad ties are typically treated with creosote, which makes them much more durable than untreated wood. Though they last longer, they don’t last forever. For the most longevity, make sure your retaining wall has a sturdy base and steel reinforcements. You should also install drainage to direct water away from the wall.

DIY is possible for small projects. Professional installation ensures structural integrity and durability for larger walls.

Regular inspection for issues like cracks or leaning and ensuring drainage stays clear.
