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 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>

Q: What is the best underpinning method?

• <div><p>Generally speaking, push piers&mdash;or steel piers&mdash;are the best option for underpinning, as they reach down to solid bedrock to find support for your foundation rather than relying on soil, which could be subject to the same issues as the soil directly below your foundation. However, the best underpinning method for your home depends on your location, how far down the bedrock is, and the type of soil in your area. Helical piers are usually the best option for sandy soil or in areas where the bedrock is too deep to use steel piers. </p></div>

Q: What’s the most affordable way to level a concrete floor?

• <div><p>Mudjacking is your best bet for leveling concrete on a tighter budget. It&rsquo;s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete&mdash;it&rsquo;s a budget-friendly option suitable for DIY enthusiasts. </p></div>

Q: Does mudjacking come with warranties?

• <div><p>Many contractors offer warranties for their work. Confirm terms before starting the project.</p></div>

They did a wonderful job--the yard looked fantastic after they finished. The one thing they did not do is remove a bunch of old concrete in the back yard, which they told me before we hired them, but I still do not understand why they couldn't remove it.
