Yes, our standard warranty is 5 years from the date of completion of the work being performed (unless other warranty terms have been written into the contract). The warranty covers resettling of the lifted concrete; as long as any of the identified causes for the settling of the concrete have been addressed properly. For example, if there is a section of the driveway that was lifted, and the identified cause was that the expansion and control joints are all open and letting water flow under the driveway and cause erosion and material displacement; the open cracks and joints would need to be properly sealed to prevent that from occurring in the future. Or if a gutter downspout was placed in an area that does not allow for the collected roof water to properly drain away from the existing concrete, that would need to be properly diverted so it does not cause the same problem with the concrete in the future.
