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 worth it?

• <div><p>Mudjacking can be an expensive foundation repair process, but in many cases, it&rsquo;s well worth the investment. This is especially true if you&rsquo;re lifting a portion of sunken foundation slab back into place. In that case, mudjacking can help avoid major structural damage and even home collapse by restoring the integrity of your structure with minimally invasive procedures. Mudjacking a concrete patio, walkway, or sidewalk can be worthwhile because it removes tripping hazards and makes your outdoor area more aesthetically appealing.</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 long do you have to stay off concrete after mudjacking?

• <div><p>Mudjacking can take <b>24 to 72 hours</b> to cure enough to resume normal use. Because the slurry mixture contains cement, it needs to fully harden to ensure that added weight won&rsquo;t shift the concrete slab before it has completely set. Your <a href="https://www.angi.com/nearme/concrete-mudjacking/">concrete contractor</a> will be able to tell you when you&rsquo;re free to use your concrete surfaces again after mudjacking.</p></div>

Q: What is the cost range for concrete injection leveling?

• <div><p>Charges correlate with surface size, settlement depth, and access, often yielding significant savings over concrete replacement.</p></div>
