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: How long does it take for polyjacking to cure?

• <div><p>The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ. </p></div>

Q: How long does mudjacking take to dry and cure before the concrete can be used?

• <div><p>Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The exact time can vary depending on the size of the project. Because the slurry mixture contains cement, it must fully harden to ensure that added weight from walking, furniture, or vehicles won't shift the concrete slab. A professional contractor can advise you on when the surface is safe to use. For comparison, if you use polyjacking instead, the polyurethane foam can dry in just a few minutes, but it's best to wait about an hour before use.</p></div>

Q: How much does mudjacking cost?

• <div><p>The average cost for mudjacking is around $1,200, though prices can range from $300 to $3,400. On a per-square-foot basis, you can expect to pay between $3 and $8, with an average of about $5 per square foot. The final cost depends on several factors, including the square footage of the concrete, the type of slab, its accessibility, whether it is load-bearing, and the type of material used to lift it. Generally, lifting a driveway, small patio, or sidewalk is less expensive than lifting a slab foundation or garage floor.</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>

"They were very good. They came by and did the work; I was very pleased with them. They were responsive and very detailed oriented. They cleaned up beautifully and they did exactly what they said they would. Their staff members were exactly what I expected. They were good, polite and nice to work with. I was very happy with them and I was happy enough to take a box of doughnuts down each morning to share with them. They were doing a good job and working extra hard under very difficult conditions. It was expensive because I wanted all the bells and whistles. I had a significant problem but their solution to the problem was far more comprehensive than anyone else that I got into to look at. They took it far more seriously and identified a basement wall that needed reinforcing. I was pleased with the entire proposal. I got lower quotes but did not feel that other people understood the problem as well. I got the value for money because I really don’t know how they could have done it for less when I saw what was involved."
