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 mudjacking or foam better?

• <div><p><a href="https://www.angi.com/articles/mudjacking-vs-polyjacking.htm">Polyjacking and mudjacking</a> can both be good solutions to sinking concrete, depending on your situation. Polyjacking, which uses expanding polyurethane foam to lift concrete, is a better option than mudjacking because the foam weighs less and won&rsquo;t contribute to additional sinking. Polyjacking can be a suitable solution for any sinking concrete slab, while mudjacking is normally only a good option for non-structural concrete, like sidewalks, patios, pool decks, and concrete driveways. However, polyjacking costs much more&mdash;as much as $25 per square foot, compared to the maximum of $6 per square foot you&rsquo;d pay for mudjacking.</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: Do concrete mudjacking companies need to be licensed?

• <div><p>Most states and municipalities don&rsquo;t require concrete mudjacking companies to carry a specific license, but they usually need to have a general contractor&rsquo;s license, and they should be fully insured. The only exception is if the mudjacking company provides foundation repairs as well, or if it offers mudjacking for home foundations. In that case, they will typically need a foundation repair contractor&rsquo;s license. You can check state requirements and then use Angi&rsquo;s <a href="https://www.angi.com/angi-license-check.htm">license lookup tool</a> to confirm that a company is properly licensed to provide mudjacking services in your area.</p></div>

Q: How much foundation sinking is too much?

• <div><p>Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. </p></div>

My driveway was totally cracked. I was scared I was going to have to replace the entire driveway. Luckily DryLock Pros was able to use the existing driveway, grind it down, and apply a new surface coat of concrete. My driveway looks brand new. Well worth the money. Highly recommend.
