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: How do you level a sunken concrete patio?

• <div><p>Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe sinking. </p></div>

Q: How much does concrete leveling cost?

• <div><p>Costs range from $500 to $1,500, depending on the size and condition of the area.</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>
