Home Improvement

The center slab is pretty thrashed and has some failing previous repairs. A couple of other slabs have more minor damage. At the very least, I'm interested in removing and repouring the center slab, but a contractor recommended against doing anything less than a full demo/replacement of the whole patio based on foundation/structural reasons.

Beyond aesthetic reasons, is this advice legit or just an upsell? If I need to do the whole thing and not just one or two slabs, I might consider pavers instead of concrete, but any suggestions are welcome.

Thanks!
