"I've only hired them to level and seal our driveway, and have yet to experience their work. However, if their work is as professional as the inspector, my excitement will definitely go through the roof."

"The concrete work Hammon-Chap Concrete, Masonry and Demolition performed was absolutely outstanding! As a member of my church’s board of management, I was tasked to find a contractor to expand the church’s driveway. Even though their quote was not the lowest, I decided to select Hammon-Chap because I felt they offered a superior product and guaranteed their work longer than the other candidates for the project. That decision proved to be a great one! From design, to excavation, to concrete pouring and finishing, to clean up, this project was completed in a few days, as promised with superb results. I was impressed with the dedication and integrity this company showed. The entire crew took pride in their work, which was evident by the truly remarkable end result. Anthony, the project manager even came back the next day to inspect the driveway. Excellent attention to detail. I most highly recommend Hammon-Chap Concrete and give them my highest recommendation."

Concrete Leveling questions, answered by experts

Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.

On average, a mudjacking repair lasts between five and 10 years, though it can sometimes last for well beyond a decade under ideal conditions. Its longevity depends heavily on several factors, including the condition of the underlying soil, environmental conditions like freeze/thaw cycles and erosion, and whether the root cause of the sinking, such as drainage issues, is resolved. Because it doesn't always fix the underlying problem of loose soil, mudjacking is often considered a temporary solution. Proper maintenance and evaluation can help extend its lifespan.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The exact time can vary depending on the size of the project. Because the slurry mixture contains cement, it must fully harden to ensure that added weight from walking, furniture, or vehicles won't shift the concrete slab. A professional contractor can advise you on when the surface is safe to use. For comparison, if you use polyjacking instead, the polyurethane foam can dry in just a few minutes, but it's best to wait about an hour before use.

A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces.
