Q: What are the benefits of mudjacking?

• <div><p>Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.</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: 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 do I maintain leveled concrete?

• <div><p>Address drainage issues, avoid heavy loads, and seal cracks to prevent future settling.</p></div>
