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: Can you lift a sinking foundation?

• <div><p>A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a <a href="https://www.angi.com/nearme/foundation-repair/">foundation repair pro</a> to determine the best way to lift your sinking foundation. </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 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>
