"Mike was able to fit me in the same day for an estimate which surprised me because I'm sure a lot of people are needing his services with all the rain lately but he was in the area that day and came by. Although the company is a nation wide chain, its a franchise and a small business. He is an honest Vermonter with Vermont values which I appreciate. He gave me options but didn't try to talk me into something I couldn't afford and is doing the work within two weeks which I was also happy about being a very busy time for this type of thing."

"We are in the second day of this project. Bryan had to hire another person to work with him as his regular employee is recuperating from an emergency situation so the work will take longer than expected. My husband says he's doing a good job ,as the work is in our vacation home in NH and I am in MA. Brian will try to have the wall finished by Thursday but will have to come back one day next week for the remaining seepage part of the job."

"Mike showed up on time and provided an estimate for the work he would perform. He and his mason arrived the next morning as agreed and his mason went to work disassembling and grinding all the mortar joints on my old chimney. We ran into an unanticipated issue that Mike quickly resolved and his mason completed the work in one full day. My wife thinks the new repair looks great. We are happy to have it fixed prior to the next heating season."

Concrete Leveling FAQs, answered by experts

Address drainage issues, avoid heavy loads, and seal cracks to prevent future settling.

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

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.

It restores concrete, prevents replacement cost disruptions, reduces trip hazards, and provides stability at a lower cost.
