"Hired them to stabilize and seal my drive way. They did a great job. It looks better than I expected. I think Angie's list underestimates costs, since the price was quite a bit higher than Angie's list estimates. But, by searching the price of materials used in poly injection, I felt like I got a reasonable price."

"Thrasher did a great job. The foreman was knowledgeable and he explained what was going to be done. We were allowed to watch the process. They leveled the front step and the sidewalk by drilling holes in the concrete and pumping foam under them until everything was level. They caulked everything when they were done and cleaned up the area. The entrance to our home looks so much better. It was well worth the money."

"Have used this company twice and would highly recommend. First time they leveled a patio that had sloped towards the house which was causing water problems. That job was done above and beyond expectations. Second time they raised the front walk from the driveway to the front porch with excellent results. Absolutely no mess with incredible results. Very willing to work with you."

"<p>When I contacted Mike he was very friendly and professional.  We scheduled for him to come out sometime during the week.  It was not an emergency and time was not an issue.  He came out to look at the needed repair in a timely manner even without the scheduled time frame.  </p> <p>After he looked at our needs he met with and reported that what we needed was something that really didn't need his services.  He told me that the concrete hadn't sunk but had moved away from the home due to the drought of 2013.  He explained many homes had the same type of problems after the drought.  He then said the concrete most likely stopped moving.  He suggested that we simply tuck point where the bricks were coming away from the exterior of the house.  He even mentioned a few companies that if needed could assist us further.</p> <p>He was honest, professional and friendly.  If we need his services (raising concrete slabs such as sidewalks, driveways, steps and such) we will use him.. You can appreciate a person that gives it to you straight even if it means they don't get the business.  </p> <p>Top Notch.<br /> <br /></p> <br />"

"Expert House Movers brought a crew of 6-8 & came in late August 2013 to start the process of raising & moving the house.  My husband had done all the prep work of disconnecting the utilities & removing the furnace, etc. They dug access ramps to the old foundation/basement with bobcats.  They poked good sized holes around the foundation so they could put in steel beams and jack up the house.  Our foundation was from 1917 & built from old creek gravel cement, so it was pretty tough.  It took three & half days to jack the house & move it over the driveway.  It seemed really fast to me.  The only thing to fall in the house was a picture off the piano.  We still had access to the house through a tall ladder to get clothes, etc. that we needed. <br /> We took over the process of arranging excavation, concrete pouring, and carpenters with more local contractors.  Expert does have concrete people & others they use in the St Louis area that know exactly the requirements needed for the new foundation. <br /> After the basement was poured & cured (curing takes about 3-4 weeks), Expert returned in October 2013 to move & set the house.  They had been in contact with the concrete man for specifications, but there were no slots for the beams when setting the house down.  A concrete worker had to come & cut those slots.  We had a carpenter on hand to finish the sill installment & make sure the sills for the permanent beams was correct & set the support posts in the basement.  We also had a friend's tractor help Expert's bobcat pull the house back over the foundation.  While all this was going on, Expert was jacking and moving supports & placing slider beams & raising & lowering the house.  The process was complete in about 2 1/2 days with care & precision.  Some of the cracks in our house even disappeared.  Great job guys. <br /> Our carpenters returned to build a staircase & some other requirements.  We are working on re-connecting utilities & returning the furnace, water heater, etc. to the new basement.  We plan to move back into the house in the first week or so in November 2013.  It's been a long process, but well worth it.  Made possible by Expert House Movers! <br />"

FAQs for concrete injection leveling mudjacking projects in Knoxville, IA

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.
