This foundation wall on the garage end of the house was backfilled almost to the top of the wall. The inside fill was five feet higher than the outside. This is called unbalanced fill. The pressure from the unbalanced fill caused the corner to crack and seperated the wall from the house. Helical Tie-Backs were chosen to reinforce the wall. Holes were drilled at each Tie-Back location.

The lead section of the Tie-Back is like a giant screw. A powerful hydralic motor is attached to a mini-excavator or skid loader. This machine screws the anchor into the earth in a downward angle until it is secured into a stable layer of earth. Extensions are added to the Tie-Backs as needed. Steel plates attach to the Tie-Backs and are tightened. The additional support from the Tie-Backs will permantly hold the wall.
