Concrete Leveling and Repair: Why Foam Jacking (Polyjacking) Is the Smartest Fix

Uneven concrete surfaces don't just look bad, they are hazardous! These unsightly surfaces can also diminish property value. Addressing these issues promptly through concrete leveling and repair is essential to maintain the integrity and aesthetics of your property. Among the various methods available, foam jacking foundation repair—also known as polyjacking—has emerged as a leading solution due to its efficiency and durability.​

Understanding Concrete Leveling

Concrete leveling is a process aimed at correcting uneven concrete surfaces by altering the foundation beneath. Over time, concrete slabs can settle due to soil erosion, compaction, or moisture changes, resulting in uneven surfaces. Traditional methods like mudjacking have been used for years, but advancements have introduced more effective techniques such as polyjacking.​

The Polyjacking Process

Polyjacking involves injecting a polyurethane foam beneath the sunken concrete slab to raise it back to its original position. The process begins with drilling small holes—typically around 5/8 inches in diameter—into the affected concrete. Through these holes, a two-part polyurethane mixture is injected. Once beneath the slab, the mixture expands, filling voids and lifting the concrete with precision. The foam then hardens, providing a stable and durable support system. ​

Advantages of Polyjacking

Polyjacking offers several benefits over traditional concrete leveling methods:​

• Lightweight Solution: The polyurethane foam used is lightweight, reducing the burden on the underlying soil and minimizing the risk of future resettlement. ​

• Quick Curing Time: The injected foam cures rapidly, often within minutes, allowing the repaired area to be used almost immediately after the process is complete. ​

• Minimal Invasiveness: The procedure requires only small injection holes, preserving the aesthetic integrity of the concrete surface and resulting in less mess compared to other methods.

• Durability: Polyurethane foam is resistant to moisture and erosion, ensuring long-lasting support and stability for the leveled concrete. ​
  
  

Comparing Polyjacking to Mudjacking

While both polyjacking and mudjacking aim to achieve similar results, they differ significantly in materials and outcomes.Mudjacking utilizes a heavy slurry mixture, which can add substantial weight to the underlying soil, potentially leading to further settling over time. In contrast, polyjacking's lightweight foam minimizes additional stress on the soil, offering a more sustainable solution. ​

Applications of Foam Jacking in Foundation Repair

Foam jacking is not limited to leveling sidewalks or driveways; it is also highly effective in foundation repair. By injecting polyurethane foam beneath a settling foundation, contractors can stabilize and lift the structure, addressing issues such as uneven floors and cracks in walls. This method provides a non-invasive alternative to extensive excavation, preserving the surrounding landscape and reducing repair time. ​

Environmental Considerations

Polyjacking is considered an environmentally friendly option for concrete leveling. The polyurethane foam used often contains a significant percentage of renewable and recycled materials, reducing the environmental footprint of the repair process. Additionally, the longevity of polyjacking reduces the need for repeated repairs, further contributing to environmental conservation. ​

Conclusion

Addressing uneven concrete surfaces promptly is crucial for maintaining safety and property value. Among the available methods, polyjacking stands out for its efficiency, minimal invasiveness, and durability. By choosing this advanced technique, property owners can ensure long-lasting repairs that uphold the integrity and aesthetics of their concrete surfaces.​
