"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

The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ.

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.

There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.

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.

A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.
