So our driveway is 8 concrete slabs approximately 12'x12' (its raining a real "goose drownder" out there so I'm not going out to measure it.)

They sit on a 30 degree slope. One of them is beginning to slide down the hill due to hydraulic subluxation or some other crazy term. Water and ice get under the slab, freeze, lift the slab slightly and away it goes.

Anyway, the slab that is sliding is beginning to push under the one below it.

Anyone ever used hydraulic jacks or cable rigging and turnbuckles to push/lift a slab up a hill?
