The material is only part of the answer. Ongoing support, water and the conditions around the slab influence what happens after a repair.
Separate the repair from the cause
A slab may have lost support because of erosion, compaction, moisture changes or other conditions. Those are possibilities to investigate, not assumptions about your property. Lifting the slab does not automatically eliminate every condition that contributed to its movement.
Ask what follow-up is appropriate
Discuss drainage, irrigation, downspouts and any separate joint or crack work that the evaluating contractor recommends. Ask what signs to watch for after the job and how to report a change. The right maintenance advice depends on the site and the work actually performed.
Read the warranty, not just the headline
Ask who issues the warranty, how long it applies, which movement is covered and what exclusions or service charges apply. Find out whether the terms transfer to another owner. A lifetime label, a material specification and a workmanship promise can mean different things.
Avoid a universal lifespan promise
An online article cannot tell you how long one property’s repair will last. Use the assessment, documented scope and actual written warranty to make the decision. A finished job photograph is useful evidence of the immediate result, not proof of long-term performance.
