Retaining Wall Installers questions, answered by experts

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

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

Poured concrete is likely the cheapest way to build a retaining wall, as this material costs anywhere from $6 to $8 per square foot. The next best budget-friendly option is to use landscaping timbers. These timbers are great for DIY projects, as they don’t require tools to successfully build a retaining wall. Landscape timber costs around $10 to $14 per square foot. Depending on your chosen garden style, you can also go with natural stones or concrete blocks. Natural stones can be expensive if you buy them, but they’re a lot less costly if you can source them from your property. 

Depending on who you hire to build a retaining wall, the average cost, including demolition and reconstruction, for a 50-foot wall that's 4 feet in height is between $7,000 and $24,000.

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.
