"It went pretty well. They tool longer than I thought, and they used a sealant (gray) that didn't match the color of our house (white) or the concrete stoop. We were planning on painting it anyway, so in the end it's not a big deal. We like Real Seal and would use them again."

"The worker who came over saw my situation and unoffically suggested a repair that would be cheap for me rather than have him and his crew come out and charge me a few thousand. I appreciated that he wanted what was best for me and not necessarily best for his company."

"It went very well, from the estimate to completion. Greg was clear, honest and direct and he cares about his customers being satisfied. The workmen arrived  on the date agreed upon, were generally neat and clean and careful about my  house. It was a big, messy job and they cleaned up well. There were a few details to finish and Greg came personally to complete the little things. For example, during the clean out and other work, a t.v. cable was pulled loose and fell between the walls.   Greg came back to fix it. He made sure I was  happy with the job. I can already notice a difference from the pebble/dirt crawlspace and the new one with the liner. I notice less dampness in the family room, and there is no more smell, even on days it is raining. I trust it will be significantly warmer in the winter.

FAQs for concrete injection leveling mudjacking projects in Union, IL

Mudjacking and foam jacking differ significantly in both materials and methods. Mudjacking uses a cement-based slurry to fill voids beneath a slab, while foam jacking uses expanding polyurethane foam delivered under high pressure to achieve superior structural support. This material distinction enhances load-bearing strength and overall stability in your repair.

Mudjacking takes between one and three days to dry completely. During this time, it's important to avoid putting weight on the slab until it's fully cured. The drying time depends on the project size and environmental conditions. In contrast, polyurethane foam used in foam jacking can cure in as little as one hour.

No, mudjacking is not a permanent fix for sinking concrete. While it effectively lifts the slab and can last five to 10 years, it doesn't address underlying soil issues that may cause future sinking. For a more permanent solution, you might consider foam jacking or complete slab replacement, which can address deeper structural problems.
