Slab Jacking of PCC Road Panels

[cohoman1]

I have several sections of pcc roadway slabs that have settled, creating rough ride. I am considering two injection products to adjust the panels to grade, power slurry injection of a grout type material or injection of a "Uretek" product. What are the pros and cons for each. What service life can I expect to see from each?

What caused the settlement?

The settlement was most likey caused by moisture seeping through the joints and cracked areas, displacing fines in the subgrade.
