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: 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: Can mudjacking be done in winter?

• <div><p>It&rsquo;s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there&rsquo;s a higher risk of damaging the slab during the drilling and lifting process in winter. </p></div>

Q: 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&rsquo;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>

"The team I worked with at BAU was great. I hired them to repair some minor vertical and horizontal foundation cracks that were found in a recent general home inspection. Everyone who came out was upbeat, professional, punctual, thorough, and highly detailed. Hunter came out first to check the entire foundation and give a free estimate. They then split the work up into two dates, and each crew was great. Michael and James came out first for the initial round, and then Alexander and Gabe came out to wrap up the last few areas. The guys were always on time, which is greatly appreciated. Both repair teams also did their own additional checks of the surrounding areas, also greatly appreciated. They were also able to provide before and after pictures, and were respectful of the property."
