The answer to the cost of a retaining wall is that it can vary significantly depending on several factors. Retaining walls are typically priced based on the size, materials used, and complexity of the project.
Generally, the cost of a retaining wall can range from $20 to $50 per square foot for a basic wall, but more complex projects or those requiring specialized materials can cost significantly more. Factors that influence the cost include the wall height, the type of soil and terrain, the need for excavation or drainage, and the choice of materials such as concrete, stone, or interlocking blocks.
