"I could not be more pleased with Joseph and the work he performed. I needed an existing patio to be replaced due to tree roots which impacted drainage towards the house foundation. After 5 bids, I decided to go with Joseph due to his competitive bid and demonstrated expertise. He and his team were stellar, solid communication, friendly, and took the time to explain to me the leveling/answering all my questions. In 3 short days the project was completed and it looks great. I would highly recommend Joseph to anyone looking for concrete work."

"Nelson and his crew did a fantastic job! We did a large concrete slab in our backyard garden, 800sf. We wanted a modern look and various shapes to fit our landscaping. Nelson did exactly what we wanted with a very positive attitude. The work was done very professionally and fast as they have all the necessary equipment. They first excavated, then put gravel and compacted it, installed rebar enforcement every 16 inches crossed, and poured the concrete. Everything was leveled, with the proper slope to take water away from home. They finally did a light broom finish. We are glad we found them on Angie's list and highly recommend them."

Concrete Leveling FAQs, answered by experts

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.

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.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

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.

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.
