"Did a great job leveling my walkway to front door and where it attaches to driveway. My worker even left me a couple tubes to chalk other cracks! Expensive though."

"I was please with the estimator, Boston's knowledge and willingness to walk me through the process and unfamiliar territory of basement waterproofing. He was very knowledgeable and answers so many questions, at the time of the walk through as well as in the days after when I had questions after receiving other bids and trying to compare them. In the end, it was just my low budget that kept me from going with Terra Firma. I thought their system was excellent, and would have worked well with my basement, but I had to opt for a less expensive design."

"We’ve had a lot of crews in our home for various projects over the years, and I have to say this was one of the most courteous. They worked hard, navigating through our kitchen to access the basement and I really appreciated their efforts. Thank you MTU, we now have safe walls in our cellar and fresh beams to keep the house standing ;)"

"Joseph is fantastic. Prompt, good communication, met deadline. He and his crew were great. Really happy with how well all three phases turned out. Our patio looks great, the driveway is perfect, and he put in a sizable wall for us. Did a really, really nice job; quality is 100% there. Would definitely hire again and would absolutely recommend. Thanks, Joseph!"

"I needed someone to put down a concrete patio for me. I had been given 3 local companies that people highly recommended. After contacting each for a bid, I was told from each company they would be out within the week to give a quote. I was never contacted from any of the companies after that. I decided to try Angi’s website and within 30 minutes of placing my “help wanted” information, I was contacted by Kano from AAA Quality Concrete and within two hours of that initial contact he was at my house and was able to give me an estimate. I feel the cost was comparable to what others have told me they paid for concrete work, but at this point I was impressed simply because of the response time I was provided. Fast forward…the patio is now complete and it looks fantastic! The crew that was here were professional and courteous. When they left after the work was completed, the work area was left clean without a sign they were here except for the new patio. I would definitely use this company again and would recommend to those needing quality concrete work."

FAQs for concrete injection leveling mudjacking projects in Kent, WA

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.
