The only drawback to this type of retaining wall is the lack of lateral strength it has. If too much water or extra pressure is exerted on the wall, it could fail in spots. Expect to pay between $15 and $30 per square foot of wall, depending on the style and strength of block you choose.
The installation of a retaining wall costs significantly more, because included with the cost of materials is the cost of labor and excavation. With cheap materials, such as blocks, the total cost per square foot would be $40 to $50.
