Uneven concrete surfaces are more than just a cosmetic problem, they can lead to safety hazards, property damage, and costly replacements. Polyjacking has become one of the most effective methods for addressing these issues with speed, precision, and durability. This article will walk you through how the process works, its benefits, and why it’s gaining popularity across residential and commercial applications.
Why Concrete Surfaces Sink and Crack Over Time
Concrete may be strong, but it’s not immune to environmental stress. Moisture changes, soil erosion, freeze-thaw cycles, and heavy loads can cause slabs to settle or crack. Left untreated, these issues can worsen, affecting everything from curb appeal to foundation integrity. Fortunately, foam injection offers a non-invasive solution that restores structural stability and surface level.
What Exactly Is Polyjacking?
Polyjacking, also known as polyurethane concrete lifting, involves injecting expanding foam beneath sunken slabs to lift and level them. Unlike traditional methods, polyjacking uses a lightweight, high-density foam that expands to fill voids and raise the concrete with pinpoint accuracy. It’s a modern answer to age-old concrete issues, clean, fast, and long-lasting.
Key Advantages of Polyjacking
- Fast application and quick cure time, with surfaces ready to use within hours.
- Minimal disruption, using small drill holes and precise tools.
- Long-term durability, as the foam resists moisture, shrinkage, and breakdown.
- Improved soil stabilization, reducing the risk of future settlement.
- Cost-effective, eliminating the need for full concrete replacement.
Step-by-Step: How the Polyjacking Process Works
Here’s how foam leveling is typically performed:
- Small holes are drilled in the affected concrete slab.
- Polyurethane foam is injected through the holes.
- The foam expands, lifting the slab and compacting the soil beneath.
- Drill holes are patched, and the area is restored.
The entire process is completed in a matter of hours, making it ideal for both residential and commercial sites.
Polyjacking vs. Traditional Concrete Repair Methods
Compared to mudjacking or complete slab replacement, polyjacking provides several unique advantages:
- Less weight on the soil, preventing additional sinking.
- Greater lifting precision, thanks to controlled foam expansion.
- Faster turnaround, without messy cleanup or long drying times.
- For driveways, sidewalks, patios, warehouse floors, and more, polyjacking delivers solid, lasting results.
Is Polyjacking the Right Choice for Your Project?
If you’re dealing with uneven, cracked, or sunken concrete, and you want a clean, reliable, and cost-effective solution, polyjacking may be the answer. It’s ideal for stabilizing surfaces without the hassle and expense of full replacement. Whether you’re a homeowner or a business owner, polyjacking can restore safety, function, and aesthetics to your property.
