A retaining wall that is crumbling, cracking or leaning is a serious safety risk and should be repaired by a professional to prevent collapse. Typically, it is possible to repair a retaining wall without the need for demolition and construction of a new structure.
The cost to repair a retaining wall depends on the cause of failure. Small sections of the wall that are not causing a significant loss in stability might only need patching with cement and are much cheaper than larger areas. If the retaining wall has failed completely, it will need to be replaced with a new one.
The cost to replace a retaining wall can run between $10 and $150 per square foot depending on the material and method used. The most common material is vinyl, but other options include wood, railroad ties, brick and concrete. Costs can also increase if drainage pipes are added or if weep holes (small holes that provide drainage and ventilation) are removed. It is important that the drainage system of a retaining wall function well to protect against water erosion.
