Mudjacking and polyurethane foam injection ​are the two primary methods often considered when it comes to concrete leveling. A crucial factor in choosing between them is understanding their longevity and how each method aligns with your long-term property maintenance goals.

Mudjacking: Traditional Approach with Limitations

Mudjacking involves injecting a slurry of cement, soil, and water beneath a sunken concrete slab to raise it to its original position. While this method has been in use for decades, its lifespan is generally shorter. Typically, mudjacking repairs last between 2 to 5 years. The primary reasons for this limited durability include:

  • Erosion Susceptibility: The slurry mixture is prone to erosion, especially in areas with poor drainage or heavy rainfall, leading to potential resettling of the concrete.

  • Heavier Material: The weight of the mudjacking material can further compress unstable soil beneath the slab, potentially causing additional settling over time.

Polyurethane Foam Injection: Modern, Long-Lasting Solution

Polyurethane foam injection, or polyjacking, utilizes a lightweight, expansive foam to lift and stabilize concrete slabs. This method offers several advantages in terms of longevity:

  • Extended Lifespan: Properly executed polyurethane foam repairs can last 20 years or more, often matching the remaining lifespan of the concrete itself.

  • Moisture Resistance: The foam is resistant to water infiltration, reducing the risk of erosion beneath the slab.

  • Lightweight Nature: Being significantly lighter than mudjacking slurry, the foam minimizes additional stress on the underlying soil, decreasing the likelihood of further settling.

Sealtite Insulation & Slabjacking: Commitment to Durability

At Sealtite Insulation & Slabjacking, we specialize in polyurethane foam injection due to its superior durability and performance. We are so confident in the longevity of our work that we offer a LIFETIME guarantee on all residential slabjacking jobs. This means if your slab settles after our repair, we will re-lift it at no additional charge.

Conclusion

While mudjacking may provide a temporary fix for uneven concrete, polyurethane foam injection stands out as a more durable and long-lasting solution. Choosing polyurethane foam not only ensures a stable and level surface for decades but also offers peace of mind with warranties like the lifetime guarantee provided by Sealtite Insulation & Slabjacking.  Contact us today for a Free Estimate.
