"Everyone we dealt with from Cantey Foundation Specialists were very professional, timely, and caring throughout the entire process from job estimate to the actual work done. While the work done did not bring all areas back completely to their original states, with the exception of one area, they were all pretty close. Realistically, It's very difficult to fix in two days what has taken place over a period of years. I am very satisfied with the job done. Grayson (job estimator) and Estevan (crew leader) were very helpful and great to work with through the entire process."

"Work done involved removing an old asphalt driveway that was cracked and bulging upwards from large tree roots, removing these tree roots, and installing a new concrete replacement driveway. Owner and contractor, Ezequiel Tejeda, provided a written contract and a very reasonable charge for these services. Despite several unforseen and some personal setbacks (truck breakdown, a LOT MORE TREE ROOTS than expected, flat tire, concrete supplier arriving 3 hrs. late), Mr. Tejeda kept the work moving forward to ensure that the buyer would have a driveway completely installed by the verbally agreed upon completion timeline. Mr. Tejeda, his righthand man, Rene, were true professional craftsmen who obviously took pride in providing the client with a top quality finished product that met or exceeded expectations. Mr. Tejeda explained each step of the process as work progressed, the products being used, and why those products had been chosen. The client's approval was sought before proceeding. All workers put in extended hours each day to get the job done in a timely manner, worked hard, and kept the work area and surrounding yard and neighborhood clean and free of trash. Overall a positive experience with an honest, reliable, hardworking contractor and a crew of top quality professional craftsmen. Would hire again. Recommended to others."

Concrete Leveling questions, answered by experts

A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

Concrete leveling is not typically covered by insurance. In some cases where the shifting concrete is caused by a natural disaster or storm, you may be able to file an insurance claim if your policy specifically covers those circumstances. In most cases, though, you’ll pay out-of-pocket for concrete leveling.

The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ.

Most projects take 1-3 hours, with immediate usability after completion.
