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: What is the difference between trenching and boring for underground utility installation?

• <div><p>Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.</p><p>Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.</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 does it take for mudjacking to dry or cure?

• <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 total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.</p></div>

Q: How long does polyjacking last?

• <div><p>Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue&mdash;like poor drainage&mdash;at the same time. The polyurethane material itself can last as long as or even outlast the concrete you&rsquo;re lifting it with. Your sunken concrete issue will likely return if you don&rsquo;t couple polyjacking with proper drainage to prevent future soil movement and sinking. </p></div>

Wanted a concrete pad but Derek noted major drainage problems. He removed grass and dirt and graded and installed new sod plus the pad. I am very pleased with the work as is the neighborhood!

Tyler was quick to look at my project and provide a bid. He had his concrete person meet with me so we were on the same page as to what I wanted. The work was completed as quickly as possible considering the weather. The finished sidewalk was exactly what I was looking for. A job well done.

"We actually had Bellos Construction do considerably more than just a bathroom remodel. Additional work included installing flooring, installing insulation and drywall, demolition work, roofing repair, etc. Overall the experience was good. Jose is very responsive and helped me out quite a bit dealing with renovating and repairing an older house that was not properly taken care of by the previous owners/renters. The only real issue we had was confirming the materials that would be installed in the bathroom (i.e., fixtures, etc). There was some miscommunication there that probably was not helped by the fact we are out of state and trying to manage a construction project. One thing that stood out about Jose was his willingness to help out with things that didn't fall under his contractual obligations. For example, he helped me transport a water tank when he didn't need to do so. If we have a need for services that Bellos Construction offers, then we will definitely consider them in the future given our experiences with them."
