Most retaining walls lean because of poor drainage behind the wall (hydrostatic pressure) or soil erosion at the base. “Patching” the cracks won’t work. At Basement Expert, we stabilize retaining walls using Active Hydrostatic Relief—installing weep holes and drainage mats—combined with structural reinforcement if necessary. By removing the water pressure, we stop the “tipping” force and extend the life of the wall without the massive cost of a total tear-down and rebuild.
