I have a standard size sidewalk slab in front of my house and it has sank on one end about 2 inches. How do you jack up the one side, and what do you put under it to hold it up?
The process is called "mud-jacking" it consists of drilling holes in the concrete and pumping a concrete mixture through the holes under the existing slab until it levels up, and to my knowledge this is not a do it yourself project. There are companies that provide this service(don't know the price) so check out the yellow pages under "mud jacking contractors".
It appears that you have access to put a 2ton car jack under the slab, right? If so, use the jack to lift the slab and support it with a wooden frame that won't sink again. Then you'll have to reinforce the corner that sank, probably by digging out the dirt and filling with a good foundation. Alot of labor; mostly shoveling.
