Retaining Wall Installers questions, answered by experts

Vinyl retaining walls are often the least expensive type of retaining wall, at $10 to $15 per square foot. This budget-friendly material is lightweight and durable, but it doesn’t have many decorative options. Untreated timber and railroad ties are the next step up, and start at $15 to $25 per square foot, respectively. High-end steel or natural stone tend to be the least wallet-friendly, but they’re extremely durable and come with a high-end look.

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

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.

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

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.
