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: Can you lift a sinking foundation?

• <div><p>A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a <a href="https://www.angi.com/nearme/foundation-repair/">foundation repair pro</a> to determine the best way to lift your sinking foundation. </p></div>

Q: How long does it take to complete the mudjacking process?

• <div><p>The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.</p></div>

Q: How long does mudjacking take to dry?

• <div><p>Mudjacking normally takes between one to three days to dry completely. The larger the project area, the more time it will take to dry. You should not walk on the concrete or place furniture or vehicles on the lifted concrete until it&rsquo;s completely cured, which a pro can help determine. If you&rsquo;re polyjacking instead, the polyurethane foam can take just a few minutes to dry, but wait an hour to be sure.</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>

I highly recommend Mitchell Masonry. Brent is very knowledgeable and does excellent work. Had new flashing installed as well as tuck pointing on my chimney. The concrete crown he installed on the chimney is a huge improvement over the original and looks great.

Beware of this contractor, do your homework. Steve is a personable guy and comes across very friendly but doesn't listen, cuts corners, and will defer you to his attorney if you have problems with his work. Our property is now de-valued because he was there. - Water lines all over the building...
