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: How do I maintain leveled concrete?

• <div><p>Address drainage issues, avoid heavy loads, and seal cracks to prevent future settling.</p></div>

Q: What are the benefits of mudjacking?

• <div><p>Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.</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: Is concrete leveling covered by insurance?

• <div><p>Concrete leveling is not typically covered by insurance. In some cases where the shifting concrete is caused by a natural disaster or storm, you may be able to file an insurance claim if your policy specifically covers those circumstances. In most cases, though, you&rsquo;ll pay out-of-pocket for concrete leveling.</p></div>
