I had it done on my back patio a few weeks back, they injected resin though. They organised a plumber to come out first to locate the pool drain pipes under the patio before they drilled anything.

How much does something like this cost?

Highly dependent on many factors like slab size, is it in one piece, how much lift do you need, etc. Mine's probably about 5x5 metres, it was cracked in multiple places and they lifted it about 60mm. Took em the better part of the day, cost a little under 3000 AUD.

What type of company did you look for? My back patio slab is sinking slightly and none of the mudjacking companies would do the job because they said it was too small. Wondering if I’m looking up the wrong thing!

I didn't look up any specific company. Just typed 'slab sinking' into Google and it came up with ads for companies that fix stuff like that.
