Foundation Settling Causing Uneven Floors — Calpe, Valencian Community

When one section of a home's foundation sinks more than the rest, floors develop a noticeable slope that makes furniture wobble, doors swing open on their own, and a marble roll to one side of the room. Differential settling is typically caused by soil shrinkage during drought, poor compaction during original construction, or plumbing leaks eroding soil beneath the slab. A foundation specialist can measure the slope with a manometer level survey, identify the root cause, and stabilize the affected section using push piers, helical piers, or polyurethane foam injection to lift the slab back toward level.
