"Aaron Lenker add Corbin Gillichbauer of Groundworks leveled concrete walks around my corner lot in Montoursville Pa. They arrived around noon time and were finished about 5 1/2 hours later. They did their work very professionally. They did an excellent job. I would rate their work 5 of 5 stars."

Introducing Concraised, Leveling your concrete so it’s as even and great looking as the day it was poured.\n\nAt Concraised we use the Foamjacking method to level & repair sunken concrete surfaces. We serve homeowners, residential and commercial property managements & municipalities.\n\nHow it works:\nConcrete slab lifting works like this:\n\n1) Injection of environmentally-safe foam under the existing concrete\n 2) Foam expands to fill the void at the same time compressing the soil underneath\n 3) Slab is raised completely back to level\n\nConcraised, making great first impressions, one perfect walkway at a time.

"Mike and his crew of expert builders did a fantastic job. Mike was offering a 20% off coupon, but even without that, his quote came in lower and with better materials than the other two companies I had quote (and I had already worked with one company on a large project). He came right out to look at the job and had a quote to me within 24 hours. He answered all my questions and we struck a deal. It took a little longer to get started than he said, but it was entirely due to the rainy weather we've had in July and early August. It seemed to pour on every start date we set. Nevertheless, he made my hard deadline with time to spare. He also did the job right -- making sure everything was level, that my plants were taken care of during the building process, ensuring that I was consulted during the building and that I had no questions, and (very important!) using the best quality materials. I am DELIGHTED with the results and know that I would not have received such excellent work or such an excellent price from anyone else. (Note that I didn't hire the company that I'd already done a huge hardscaping project with the year prior....). He even powerwashed my walkway and a concrete area as well as my driveway where he'd stored some materials. Mike is pleasant, customer-orientated, honest, and delivers above expectation. His crew is polite, efficient, and really good at what they do. I watched the guys who built the divider wall and they spent a lot of time picking through the pile of former-chimney rocks to find just the right ones and to lay them in perfectly. They were all so professional and nice that I shared a beer with them at the end of one day's work. Fantastic experience and end-result. Can't wait for the rain to stop so I can use it!"

Concrete Leveling questions, answered by experts

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. 

On average, a mudjacking repair lasts between five and 10 years, though it can sometimes last for well beyond a decade under ideal conditions. Its longevity depends heavily on several factors, including the condition of the underlying soil, environmental conditions like freeze/thaw cycles and erosion, and whether the root cause of the sinking, such as drainage issues, is resolved. Because it doesn't always fix the underlying problem of loose soil, mudjacking is often considered a temporary solution. Proper maintenance and evaluation can help extend its lifespan.

The average cost for mudjacking is around $1,200, though prices can range from $300 to $3,400. On a per-square-foot basis, you can expect to pay between $3 and $8, with an average of about $5 per square foot. The final cost depends on several factors, including the square footage of the concrete, the type of slab, its accessibility, whether it is load-bearing, and the type of material used to lift it. Generally, lifting a driveway, small patio, or sidewalk is less expensive than lifting a slab foundation or garage floor.

Most states and municipalities don’t require concrete mudjacking companies to carry a specific license, but they usually need to have a general contractor’s license, and they should be fully insured. The only exception is if the mudjacking company provides foundation repairs as well, or if it offers mudjacking for home foundations. In that case, they will typically need a foundation repair contractor’s license. You can check state requirements and then use Angi’s license lookup tool to confirm that a company is properly licensed to provide mudjacking services in your area.

Yes, you can mudjack cracked concrete, but the cracks will need to be repaired once the concrete has been leveled. If the concrete is severely cracked in multiple places, replacement may be a better option, but for less severe cracking, mudjacking is a good solution as long as cracks are correctly caulked and sealed.
