If you’re a homeowner or property manager, you’ve probably faced the challenge of uneven and cracked sidewalks. Not only do they create an eyesore that detracts from your property’s curb appeal, but they can also pose a significant safety hazard. The good news is there’s a quick, affordable sidewalk leveling solution that doesn’t involve ripping out and replacing concrete slabs—it’s called polyjacking.
What Is Polyjacking?
Polyjacking, often called polyurethane foam injection, is a cutting-edge technique for leveling uneven sidewalks and other concrete surfaces like driveways, patios, and pool decks. This innovative process involves carefully injecting a high-density polyurethane foam beneath the concrete slab. Once injected, the foam expands and fills voids, lifting the sidewalk back to its original position, or as close as possible without causing damage.
This method restores the surface and enhances the slab’s structural integrity, providing a long-lasting solution to common issues such as settling or cracking. It’s akin to giving your sidewalk a new lease on life, allowing you to maintain safety and aesthetics without the hassle and high costs associated with complete replacement. Additionally, polyjacking is quick and minimally invasive, making it a convenient option for homeowners and businesses alike.
Why Choose Polyjacking Over Traditional Methods?
Traditionally, sidewalk leveling was done either using a technique called mudjacking or by digging up and replacing the uneven slab. While mudjacking and replacement work, technological advancements have introduced polyjacking as a superior alternative to both. Here’s why polyjacking outshines both slab replacement and mudjacking:
1. Cost-Effectiveness
Replacing an entire concrete slab can be costly. Your expenses can add up quickly between labor, materials, and the time it takes to complete the job. Polyjacking, on the other hand, is significantly more affordable. The materials used in polyjacking are less expensive than new concrete, and the process requires less labor, translating to lower costs for homeowners and property managers.
2. Speed And Efficiency
One of the most attractive benefits of polyjacking is its speed. The process can typically be completed in a few hours, compared to days or weeks, if you opt for slab replacement. There’s no need to wait for concrete to cure; you can walk or drive on the repaired sidewalk almost immediately after the polyjacking process is complete.
3. Minimal Disruption
When replacing a sidewalk, you often have to deal with the noise, dust, and disruption that comes with heavy machinery and demolition. Polyjacking is a much quieter process and creates far less mess, making it a more neighbor-friendly option.
4. Long-lasting Results
Polyurethane foam is water-resistant and won’t erode over time like the cement slurry used in mudjacking. This means that polyjacking provides a more durable and lasting solution, even in areas with frequent rain or poor drainage.
5. Environmentally Friendly
Polyjacking is an eco-friendly option. The process uses less energy and produces less waste than traditional concrete replacement. The polyurethane foam is also made from recycled materials, making it a sustainable choice for environmentally conscious homeowners.

How Does Polyjacking Work?
Let’s break down the polyjacking process so you know exactly what to expect:
- Assessment: Experts assess the area to determine the extent of the leveling required. This includes identifying the cause of the settlement, whether due to soil erosion, poor drainage, or other factors.
- Drilling: Small, strategic holes (typically less than an inch in diameter) are drilled into the affected concrete slab.
- Injection: The polyurethane foam is injected through the holes. It expands beneath the slab, filling voids and lifting the concrete slab.
- Finishing Touches: Once the desired level is achieved, the injection holes are filled with a concrete patch, leaving your sidewalk as good as new.
- Cleanup: The area is cleaned up, and the site is left tidy and usable, all within a few hours.
Comparing Polyjacking To Mudjacking
While mudjacking also aims to lift and level uneven concrete, it uses a mixture of water, soil, and cement (called slurry) to achieve this. Here’s how polyjacking stacks up against mudjacking:
- Weight: One of the significant advantages of polyurethane foam is its lightweight nature compared to the traditional slurry used in mudjacking. This reduced weight minimizes the risk of further sinking or settling of the sidewalk, ensuring that the structure remains stable over time without the added burden of heavy materials.
- Precision: Polyjacking offers a level of precision that is hard to achieve with mudjacking. The technology allows for meticulous control over the lifting process, making it possible to adjust the height in small increments. This ensures that the slab is level and stable.
- Curing Time: The curing time of materials is a critical factor in any repair project. Polyurethane foam cures in minutes, allowing for a quick turnaround and minimal disruption. In contrast, mudjacking slurry can take hours or even days to set completely, delaying subsequent work and leading to longer project timelines.
- Water Resistance: One of the standout features of polyurethane foam is its water-resistant properties. Unlike traditional slurry, which can absorb moisture and deteriorate over time, polyurethane foam effectively repels water. This characteristic helps to prevent future erosion and damage to the foundation, ensuring the longevity of the repair and the safety of the structure above.
When To Consider Polyjacking?
While polyjacking is an excellent solution for many situations, it’s essential to understand when it’s the right choice:
- Minor to Moderate Settling: This solution is ideal for sidewalks that have sunken due to soil compaction or erosion. It addresses issues like uneven surfaces that can pose tripping hazards, ensuring pedestrians can navigate safely and comfortably.
- Time-Sensitive Repairs: This approach allows for swift restoration of walkways, perfect for property managers who need quick fixes with minimal downtime. It helps maintain safety and aesthetics, enabling foot traffic to resume promptly without significant disruptions.
- Environmentally Conscious Projects: This method minimizes environmental impact while making repairs. Utilizing sustainable materials and practices enhances the infrastructure and contributes to the broader goal of preserving our planet for future generations.
How To Help Prevent Concrete Slabs From Becoming Uneven
Preventing concrete slabs from becoming uneven starts with proper installation and continues with regular maintenance.
Firstly, ensure a solid foundation by compacting the soil properly before pouring the concrete. This helps avoid future settling due to soil compaction or erosion.
Additionally, using a gravel base can promote better drainage and prevent water accumulation that might cause the slab to shift.
Regular maintenance, such as sealing the concrete, can protect it from moisture damage and prevent cracks.
Good drainage around the slab is also important to prevent erosion and problems related to expansive soil.
Finally, visible cracks or shifts should be addressed promptly to avoid more severe issues in the future.
Sidewalks are more than just a pathway—they’re critical to your property’s aesthetic and safety. Choosing poly jacking for sidewalk leveling ensures you protect both aspects efficiently and affordably.
