Slab Jacking

[DimeBag]

Has anyone bought or made anything to fix a sunken driveway? Was thinking of using a 12 ton bottle jack or making something.

if you mean lifting a slab, there are special contractors who can lift it with concrete injected under it.

Like they said.
My old man had it done 18 or so years ago on part of his drive. And more recently in his attached single car.
Both with great success, cheaper then new concrete. But still costly.

google uretek they pump high pressure foam that lifts the slab then hardens to keep it there.

It's not cheap. Sometimes more practical than jack hammer and new pour. The difference on mine was only about $200 for the driveway to garage slab.

That's how TxDOT "fixed" I-59 north of Humble many years back. Giant mud jacking operation. And it was still a washboard interstate when they got done with it.

The one corner of my 24 x 36 garage floor dropped about 1.5''. The area that dropped took in about a 12 x 15 area from the corner out. I had a company come out and gave me a price to bore the small holes and pump the concrete in to raise it back up. The cost I was given was in the $7000 range. It would be MUCH less expensive to cut that 12 x 15 section out, add the proper fill and put in new concrete.
