Does expanding foam lift concrete?

• <div><p>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 <a href="https://www.angi.com/articles/mudjacking-vs-polyjacking.htm">polyjacking over mudjacking</a> for more damaged and delicate slabs.</p></div>

Q: Is there an alternative to underpinning?

• <div><p>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.</p></div>

Q: What materials are used in mudjacking?

• <div><p>A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.</p></div>

Q: How long does mudjacking last?

• <div><p>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.</p></div>

Q: Does mudjacking come with warranties?

• <div><p>Many contractors offer warranties for their work. Confirm terms before starting the project.</p></div>

"They were responsive to every call, did the work professionally and cleaned up nicely. We would not hesitate to recommend them to friends and family. We had two leaning columns in the back yard that are now straight and piered so they will never shift again. They then removed a large area of cracked cement and relayed. It looks fantastic!
