What can contribute to settlement?
- Underlying fill can settle over time, leaving support voids beneath the concrete.
- Soil erosion can also remove support, allowing a slab to move.
- A visible crack or uneven joint is a symptom, not proof of the cause.
- It is not a structural foundation diagnosis, and a visible joint alone cannot establish one.
What should be assessed together?
- Record which slabs are affected and where the unevenness appears.
- Note how the condition has changed over time, with dates or photos if you have them.
- Share any water observations and how neighboring surfaces meet the slab.
- Have the actual support, concrete condition and repair goal assessed before choosing lifting or replacement.
Does lifting fix every underlying issue?
No. Lifting does not automatically repair drainage, pipes or a structural foundation. If an assessment finds those concerns, ask for them to be identified and scoped separately, so each problem is handled on its own terms rather than treated as a routine lift.
