"I had a small but complicated, hard to access, and structurally essential repair job on a 60-year-old concrete deck attached to my 280-year-old Pennsylvania limestone farmhouse. I contacted several masons listed for my area on Home Advisor, and included Mr. Grady as a long shot -- I read about his expertise with historical structures and wished I had access to such an expert craftsman, but I didn't think he'd be interested in my teeny job and assumed I wouldn't be able to afford him anyway. He was the first one to return my call and to look at the job, and I thought his price was fair. I believe now it was way more than fair, considering the time he spent. He did extensive research, going over a structural engineer's report I had done previously on the deck and even examining the original architectural drawings and materials invoices from 1959. He showed up at least three times to complete the repair in stages, and has been back a half a dozen times since then to check the job -- and my location is not exactly in his neighborhood. He accepted only enough payment in advance to pay for lodging for himself and his assistant when they stayed nearby one night in order to be there early the next morning. He gave and continues to give free advice about preserving my stone house and patio. If you prod him a little, he might even share some of his personal philosophy, earned over a lifetime of work that is clearly more of an art form than a job to him. Overall, I'd say you can hire one of many competent contractors and get an adequate job, or you can hire Mr. Grady and get superior work by someone who cares about your property as much as you do."

House Leveling questions, answered by experts

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.

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.

Mudjacking is suitable for sidewalks, driveways, patios, and nearly all exterior flat structures. However, it may not suit severely damaged or heavily cracked areas.

It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.

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.
