Concrete surfaces, such as driveways, patios, and sidewalks, are essential for both residential and commercial properties. Over time, these surfaces may become uneven due to soil erosion, water infiltration, or Edmonton’s harsh freeze-thaw cycles. Addressing these issues promptly is crucial to avoid safety hazards, water drainage problems, and structural damage. Two popular methods for fixing uneven concrete are mud jacking and polyurethane foam lifting, each with distinct pros and cons. However, polyurethane foam lifting has emerged as the superior choice for most Edmonton properties.
What is Mud Jacking?
Mud jacking, or slab jacking, is a traditional technique that involves pumping a slurry mixture of cement, water, and soil underneath a sunken slab. This mixture fills voids under the concrete and lifts the slab back to its original position. While this method has been in use for decades, it has significant drawbacks that make it less desirable compared to modern alternatives.
How Mud Jacking Works:
- Holes, typically 1-2 inches wide, are drilled into the concrete slab.
- A hydraulic pump injects the slurry mixture under the slab.
- As the mixture hardens, it lifts the concrete to the desired level.
The Cons of Mud Jacking
Despite its widespread use, mud jacking has several downsides that make it less effective for long-term concrete repair in Edmonton.
1. Short Lifespan
The slurry used in mud jacking is heavy and can lead to additional settling over time. This is especially problematic in Edmonton, where unstable soils and frequent freeze-thaw cycles exacerbate the issue.
2. Invasive Process
Mud jacking requires large holes to be drilled into the concrete surface, which can weaken the slab and leave visible scars even after repair.
3. Environmental Concerns
The slurry mixture used in mud jacking contains soil and water, which can erode over time and wash away, leaving voids that cause the slab to settle again.
4. Slow Curing Time
Mud jacking repairs can take several days to fully cure, during which time the area must be avoided. This can disrupt homeowners or businesses relying on those spaces.
5. Cost Inefficiency Over Time
While mud jacking may seem affordable initially, the likelihood of recurring issues means additional costs in the long run. This makes it less cost-effective compared to modern alternatives.
What is Polyurethane Foam Lifting?
Polyurethane foam lifting is an innovative solution that uses a lightweight, expanding foam to lift and level concrete slabs. It offers a faster, more durable, and less invasive option for homeowners and business owners.
How Polyurethane Foam Lifting Works:
- Small holes (about ⅜ inch in diameter) are drilled into the concrete slab.
- A specialized polyurethane foam is injected into the holes.
- The foam expands, filling voids and lifting the slab to the desired level.
- The foam hardens quickly, providing a stable and durable foundation.
The Pros of Poly Foam Lifting
Polyurethane foam lifting has become the go-to method for concrete repair in Edmonton, offering several key advantages over mud jacking.
1. Durability and Longevity
The lightweight nature of polyurethane foam prevents further settling, even in areas with unstable soil. It also resists moisture and erosion, making it ideal for Edmonton’s climate.
2. Minimal Disruption
With smaller drill holes and faster curing times (typically less than 30 minutes), poly foam lifting is far less invasive than mud jacking. This allows homeowners and businesses to resume normal activities almost immediately.
3. Eco-Friendly Solution
Polyurethane foam is environmentally friendly, as it doesn’t erode or wash away like the slurry used in mud jacking. Its lightweight composition also reduces strain on the underlying soil.
4. Cost-Effective Over Time
While the upfront cost of poly foam lifting may be slightly higher than mud jacking, its long-lasting results make it a more economical choice in the long run. Homeowners and businesses save money by avoiding repeated repairs.
5. Precision and Control
The expanding foam allows for precise leveling, ensuring that the concrete is restored to a uniform, even surface. This is particularly important for areas like patios and walkways, where aesthetics matter.

Why Edmonton Properties Benefit from Polyurethane Foam Lifting
Edmonton’s climate poses unique challenges for concrete surfaces. The city’s freeze-thaw cycles cause significant soil movement, leading to uneven or sunken slabs. Polyurethane foam lifting is particularly well-suited for these conditions because of its ability to withstand moisture, resist temperature fluctuations, and provide a stable, long-lasting solution.
Key Benefits for Edmonton Residents:
- Faster repairs to minimize disruptions during busy seasons.
- Effective in addressing freeze-thaw damage and preventing further settling.
- Ideal for both residential and commercial applications, from driveways to warehouse floors.
Conclusion: Why Choose Polyurethane Foam Lifting?
For Edmonton homeowners and businesses looking for a reliable, durable, and eco-friendly solution to uneven concrete, polyurethane foam lifting is the clear winner. While mud jacking has served as a traditional method, its limitations make it less effective in the long term. Polyurethane foam lifting offers precision, longevity, and cost efficiency, making it the superior choice for Edmonton’s challenging climate.
