"We hired them to excavate a collapsed drain pipe, widen and extend our gravel driveway, and then asphalt pave the gravel. They did a great job communicating what was going on and when. Would definitely hire them again."

Retaining Wall Installers questions, answered by experts

To maintain the integrity of your landscape, a retaining wall must be installed if the slope of the angle exceeds 35 degrees. The lean of the wall must be 1 inch per 12 inches in height to disperse the weight of the soil uniformly and guarantee the correct drainage of the soil.

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.

Generally speaking, a retaining wall should be between 3 and 4 feet high, depending on variables such as the wall-building material, the purpose of the retaining wall, and more. If you want your retaining wall to be taller than 4 feet, check with your local building ordinance office for the maximum allotment. You may also need a special permit for retaining walls over 4 feet tall.

Options include concrete, stone, brick, and wood, tailored for specific design needs.

Poured concrete is often the cheapest material for a retaining wall, costing around $6 to $8 per square foot. Other budget-friendly options include vinyl and landscaping timbers, which range from $10 to $15 per square foot; landscaping timbers are particularly well-suited for DIY projects. Untreated timber and railroad ties are a step up in price, starting at $15 to $25 per square foot. Natural stones can also be a cost-effective choice if you can source them from your own property, but they can be expensive to purchase. High-end materials like steel are typically the most expensive but offer superior durability and aesthetics.
