There are several ways to repair a buckled sidewalk.  Some are less costly than others, and some are not necessarily recommended, but are still options.
Concrete Raising or Slabjacking –
This method lifts the concrete sidewalk slabs to their original position by pressure injecting either cement or a non cement material underneath the sidewalk.  It’s only effective on sunken sidewalks and is rarely warranted as the contractor has no idea what is underneath the sidewalk.  It’s hard to tell just why the sidewalk sank and what condition the ground underneath the sidewalk is in.  The greater the slab needs to be re-adjusted, then the greater the possibility is that the slab will re-adjust and settle again.
Concrete Grinding – This method removes trip hazards in sidewalks by removing a thin layer of concrete, therefore reducing slight protrusions.  After grinding, the sidewalk surface is then left even on both sides with a gradual slope instead of a trip hazardous edge.  This is a great alternative if the protrusion between slabs is between 1/2″ to 1″.

Replace the Sidewalk –
This process requires the bad portion of the sidewalk to be broken down and removed.  The underneath ground will be stabilized, new rebar will be placed and new concrete will be poured.
