The foundation stabilizer includes a bearing plate (31) that is mounted in a stationary position on the upper end of a ground anchor (20). A foundation lifting bracket (28) is positioned below the bearing plate (31) and lifting screws (57, 58) are connected at their lower ends to the foundation lifting bracket (28) and extend upwardly through openings in the bearing plate (31) for lifting the foundation lifting bracket with a jack (63) temporarily mounted on the bearing plate. The foundation lifting bracket (28) is configured so that it does not exceed the height of the bearing plate (31) when it is raised by the lifting screws (57, 58).
