Yes, polyurethane foam (also known as polyjacking) is generally considered a superior alternative to traditional mudjacking for concrete slabs due to its durability, speed, and minimal impact on the property.

Key reasons why polyurethane foam is often the better choice include:

• Longer Lasting Results: Polyurethane foam is waterproof and has a closed-cell structure that resists water intrusion and erosion. While traditional mudjacking slurry can wash out and settle over time, polyjacking provides a stable base that can last 10 years or more.
• Immediate Use: Polyurethane foam cures in roughly 15 minutes, allowing slabs and driveways to bear weight immediately. In contrast, mudjacking requires a 24- to 48-hour waiting period before the surface can be used.
• Minimal Damage: Polyjacking requires much smaller drill holes (only 5/8″ to 1″ in diameter) compared to the large 1.5″ to 2.5″ holes needed for mudjacking. This results in less damage to the existing concrete and a cleaner finish.
• Weight and Soil Health: The foam is lightweight and does not add significant stress to the underlying soil. Traditional mudjacking uses a heavy cement slurry that can actually cause further sinking by adding excess weight to expansive clay soils.
• Superior Voids Filling: The foam expands as it is injected, ensuring it fills all subsurface voids comprehensively and provides more precise leveling control.
