You have three options: coat the sunken section with a sand-and-cement mixture to make the surface higher, raise the sunken section using a process called mudjacking, or raise the sunken section using expanding polyurethane foam. Patching fixes the safety issue without costing much, but the patch is sure to show.
Thereof, Can you do PolyLevel yourself?
PolyLevel can be installed in just one day, through smaller, dime-sized holes drilled in the concrete and just 15 minutes after installation you can walk or drive over the slab! … You can avoid this expense if you do it yourself with the help of a jacking pump, which can raise the concrete slab to the needed level.
Also to know is, How do you fix a sinking concrete foundation? Mud jacking can lift a settled concrete slab by pumping a grout through the concrete and pushing it up from below. The process is sometimes called “slab jacking” or “pressure grouting”. 1 to 1 5/8th inch diameter holes are drilled through the sunken concrete block/slab at strategic locations to maximize lift.
Subsequently, question is, Do it yourself foam jacking?
Also, How much does it cost to lift a sidewalk?

Does foam jacking last?
Mudjacking can last for long periods, but it is inherently less reliable and usually does need to be replaced. The injected materials are extremely heavy (30-50 times heavier than their polyurethane equivalent) and can cause a new round of soil compression (and foundation sinking) beneath the slab.
