01
Is the proposed repair justified?
Replacement can be the better choice for layout or finish even when lifting is feasible.
- Ask why lifting fits the slab and its support conditions, rather than accepting it as a default.
- Ask what result the repair is meant to achieve and what will stay unchanged, such as existing cracks or surface wear.
- If the concrete is severely deteriorated or the layout must change, ask whether replacement is the better comparison.

Compare proposals on what each one includes
Water-related and structural concerns are comparison questions, not promises of included work.
Swipe across the table to compare all columns →
| Scope item | What to ask | Why it matters |
|---|---|---|
| Affected slabs | Does each proposal name the exact slabs, not just the general area? | Lifting one walk and a whole driveway are different jobs. |
| Method | Which lifting method is proposed, and why does it suit this slab? | Foam and grout or slurry are different approaches, and installer assessment matters. |
| Preparation and access | What is done before work starts, and what access is needed? | Access shapes schedule, disruption and what needs protecting. |
| Finish and cleanup | What is included for the surface and debris after work? | Clarify surface work and cleanup rather than assuming either is included. |
| Exclusions | What is not included, such as water control or structural work? | Those concerns may need a separate scope rather than being assumed. |
03
What must be clear before work begins?
- Confirm whether any public authority review applies to the proposed work, and who handles it.
- Agree on scheduled access and the return-to-use instructions for the chosen process.
- Read any written warranty and price terms carefully, and do not assume a universal rate or guarantee.
