"I had Christian lift some concrete on my back patio to save my downstairs ac unit from shorting out from puddles forming from the heavy rains. They were able to complete job without moving or Uninstalling the ac unit. Kudos to Jason for putting up with me while he explained the process after other household issues were brewing after a bad storm. Thanks for saving my AC unit. Front edge of unit is not underwater after rain now."
"Thrasher did an excellent job repairing our driveway. They leveled out the entire driveway with amazing precision, and they fixed all the gaps with an attractive sealant that blends beautifully with the concrete. All of the team members I interacted with were professional and polite. I am very pleased with the results and only wish I’d called them sooner."
"They were on time and did the job pretty quickly. After an hour that they finished the work, it rained. Until now, it's still raining so I can't say much about the quality yet. Their work was under warranty so I'll just call them if needed."
"Our basement wall had settled over five inches. They piered the front basement wall and brought it back up to level. The basement wall was beyond repair. They cut a section of the back basement wall and demolished the entire back wall and poured me a new basement back wall. Great job guys!!! "
"My front walkway had sunk unevenly at either end and was at minimum a tripping hazard much less ugly to see. Due to the fact that a large koi pond was only a foot away from the walkway i was extremely skeptical of the possible damages from any type of repair / replacement of walkway, however Robert and the crew at Elevated Concrete Lifting was more than professional and took into consideration the integrity of the pond and more importantly the fish, everything was properly covered so that any debris would not contaminate the water. Not only the repairs but the crew and their professionalism far exceeded my expectations. Thank you."

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 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.
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.
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.
