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: What is a good slump height?

• <div><p>A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces. </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: Can mudjacking be used for all types of concrete floors or surfaces?

• <div><p>Mudjacking is suitable for sidewalks, driveways, patios, and nearly all exterior flat structures. However, it may not suit severely damaged or heavily cracked areas.</p></div>
