"I have had two issues since they installed the new sump pump and irrigation. Issue number one was water still getting passed the new concrete. The other issue is that the new concrete was not level at all which has caused issues with the new flooring I installed. However, their customer service is top notch and will work hard to take care of you."

Concrete Leveling questions, answered by experts

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

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.

Many contractors offer warranties for their work. Confirm terms before starting the project.

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.

Charges correlate with surface size, settlement depth, and access, often yielding significant savings over concrete replacement.
