To repair retaining walls, we will typically either recommend wall anchors or helical tiebacks to restore structural integrity. Both wall repair techniques use a steel beam bracket anchored on the exterior of the retaining wall to brace and distribute pressure from the grip clamps. Although both wall anchors and helical tiebacks are typically used, your contractor will also attempt to restore the foundation to its original position. To keep from slipping down, these materials are anchored with an anchor rod that is drilled into a 1″ deep hole in the wall. The rod extends “x” feet beyond to be fastened with earth anchors or piles on the other side of the retaining wall.
Once fully assembled, the wall plate is installed and set in place. The rod assembly can then be tightened, which may straighten the wall back to its original position. To prevent erosion, helical anchors are installed from the exposed face of the retaining wall. They are mechanically inserted through a hole cut in the wall and their blades pull them deep into the soil and secure them there. When the hole in a retaining wall is closed, a framing stud is installed over the protruding threaded rod and a nut is tightened onto it to brace the wall. Wall anchors are generally the more inexpensive solution to repairing a retaining wall, but in some cases anchors cannot be installed. This includes situations where hard, rocky soil is an issue or when space restrictions make drilling beyond the retaining wall impractical.
