This is also called Pressure Grout injection, and it's very effective, basicallly creating columns up to 12 ft below grade. If you look into it, I'd have a very frank conversation with the contractor about potential damage to the pool walls, since that much pressure can create shifting or even cracks if not applied carefully. That risk varies by soil types and the solidity of the pool walls naturally.

Just personally, I'd discourage covering over the concrete without addressing the underlying cause. We had the exact same appearance of deck settlement around our pool & it turned out there were large voids (an understatement!) underneath the deck. I posted pics here- Let's just say the settlement on top may be the tip of the iceberg. Your repair will be different if you're located on a hillside (retaining wall, drainage, new deck, etc) or surrounding level ground. An local engineer may be helpful.
Good Luck.
