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!
If money is limited, I'd just take out the two large center sections and inspect/repair the substrate. This is probably bad preperation underneath and there's slumping and/or frost heaving. Once you have that part removed, you might decide the other areas aren't much better underneath. Then you can decide to repour concrete or move on to a different style of patio, like pavers or a wooden deck.
