While you cannot undo the historical structural trauma or erase existing cosmetic cracks without extensive interior and exterior repairs, you can successfully halt active subsidence and physically lift or stabilize a sinking building back toward its original level. Structural engineers achieve this using advanced geotechnical methods such as synchronized hydraulic jacking paired with steel underpinning piles driven deep into stable bedrock, or high-pressure structural resin injection that compacts weak sub-soils and restores a level foundation base.
