When your concrete sinks or cracks, you have options. Two common methods are mudjacking (pumping a limestone and cement mixture beneath the slab) and polyjacking (injecting polyurethane foam). Here’s why polyjacking is often the preferred solution for Northern New Jersey homeowners, commercial properties and municipalities.
1. Speed of Installation
The poly foam used in polyjacking sets within minutes, allowing immediate use of your concrete surfaces. Mudjacking can take hours to cure and tends to require multiple applications.
2. Longevity and Stability
Polyurethane foam is lightweight yet strong, stabilizing soil and preventing future erosion and sinking. Mudjacking is heavier and can fail over time due to weight and soil erosion.
3. Precision and Minimal Damage
Polyjacking requires smaller injection holes (about the size of a dime), resulting in less disruption and a cleaner finish. Mudjacking requires larger holes prone to cracking that can leave unsightly surfaces and substandard results.
4. Environmental Considerations
Polyurethane foam is environmentally neutral, thereby leaving no environmental imprint. Polyjacking reduces concrete waste, as it lifts existing slabs instead of replacing them entirely, making it a greener choice.
5. Cost Efficiency
Although both methods are less expensive than full replacement, polyjacking often provides longer-lasting results with fewer follow-up service.
At Sidewalk Savers, we use state-of-the-art polyjacking technology to lift, eliminate potentially dangerous variations in slab heights, and protect concrete surfaces for long term value.
