Q: What does the concrete injection leveling/mudjacking process involve?

• <div><p>The method involves lifting settled concrete using pressurized cement slurry via drilled holes. This solves uneven surfaces and prevents further settling.</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.

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>

Q: Can you mudjack cracked concrete?

• <div><p>Yes, you can mudjack cracked concrete, but the cracks will need to be repaired once the concrete has been leveled. If the concrete is severely cracked in multiple places, replacement may be a better option, but for less severe cracking, mudjacking is a good solution as long as cracks are correctly caulked and sealed.</p></div>

Sam and his crew are very professional . They repaired leaking roof vents and other problems that we weren't aware of until Sam went up on the standing seam metal roof. He took before and after pictures which we really appreciated. I would definitely recommend Sam and Next Level Roofing.
