"This was the first time I had used their services. They showed up when they said they would, did not make a big mess, cleaned up and then left. Everything is A-o.k. I had to call them back because the sump pump I felt was going off too often. I tired calling about this problem several times but they waited 3 weeks until the manager finally called me back. They came back out and told me that everything was running okay. The dehumidifier they installed had a water level too low and was unable to drain properly. From my suggestion they put up two by four blocks to solve this problem. I still don’t think that it’s draining properly. The guys that came out didn’t seem to have good answers to the questions that I asked. I’m going to call them up to see if they can send out more knowledgeable workers."

Concrete Leveling questions, answered by experts

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

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.

Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe 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.

Mudjacking is your best bet for leveling concrete on a tighter budget. It’s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete—it’s a budget-friendly option suitable for DIY enthusiasts.
