Sorry to hijack this thread, but I too am looking at slabjacking or concrete raising companies. I'll post pics tomorrow, but I have 2 cracks that aren't level (and a few others which are level, and so I therefore don't care as much about those). The pool is concrete/plaster, prob 20-30 years old and in decent shape, and same for the concrete pool deck so I'm not worried about further settling of the deck.
My main concern is that these 2 uneven cracks are in the area between the pool and my pump/filter/heater. Probably a 20 ft wide area overall, but there's always the chance that drilling the holes for the concrete raising ends up hitting one of the return or supply lines, or elec conduit for the pool light. This would be worst case, but a pretty big problem to deal with. I'm not sure where the pipes are since I'm not the original homeowner, and not sure how anyone could locate the pipes. Maybe take a fairly educated guess, but who's to say that the pool wasn't built in a really weird way laying out the pipes.
How do these companies make sure they don't drill down into pool pipes??
