Sunken Concrete Slab Near Foundation: Can You Regrade Over It?

A concrete slab that has settled 6–10 inches toward the house indicates serious subsidence, likely due to uncompacted backfill. Simply adding fill on top will not fix the underlying void and may worsen water intrusion. This is a structural issue requiring a home inspector or structural engineer to assess foundation integrity before any grading work. Do not proceed without professional evaluation.
