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: Which is better for lifting concrete: polyjacking or mudjacking?

• <div><p>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&mdash;as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.</p></div>

Q: What’s the most affordable way to level a concrete floor?

• <div><p>Mudjacking is your best bet for leveling concrete on a tighter budget. It&rsquo;s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete&mdash;it&rsquo;s a budget-friendly option suitable for DIY enthusiasts. </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: Is concrete leveling worth it?

• <div><p>Concrete leveling is absolutely worth it if you have sunken concrete slabs and want to restore them to level, especially if the slab is part of your home foundation. Concrete leveling is less than half the price of replacing concrete sidewalks, patios, walkways, and pool decks, and it&rsquo;s about a quarter of the cost of replacing a foundation. If you also treat the underlying problem, it can be a worthwhile and permanent solution. </p></div>
