Comparing Foam Jacking vs Mudjacking in Calgary
In Calgary’s challenging climate, Concrete Experts helps residential and commercial clients tackle uneven concrete surfaces using two primary methods. But which one is better? Foam Jacking vs Mudjacking. Understanding the differences between these methods is crucial for choosing the most effective solution.
What Is Mudjacking?
Mudjacking is a traditional concrete lifting method that’s been around for decades. It involves pumping a slurry made of water, dirt, sand, and cement underneath the sunken slab to lift it back into place. This mixture is pumped through holes typically 1 to 2 inches in diameter.
- Pros of Mudjacking –
- Utilizes Natural, Readily Available Materials
- Effective for Heavier Slabs and Large Voids
- Often Less Expensive up Front
- Cons of Mudjacking –
- Heavier Material May Contribute to Future Settling
- Longer Cure Time (Up to 48 Hours)
- Larger Drill Holes Mean a More Noticeable Patch Job
- More Vulnerable to Water Erosion, Especially in Freeze-Thaw Conditions
What Is Foam Jacking?
Foam jacking uses high-density polyurethane foam to lift concrete. The foam is injected through much smaller holes—about the size of a dime (⅝ inch)—and expands under the slab to fill voids and raise it.
- Pros of Foam Jacking –
- Lightweight Material Reduces Load on Unstable Soils
- Expands Quickly and Sets in as Little as 15 Minutes
- More Precise Lift With Better Long-Term Stability
- Water-Resistant and Chemically Inert
- Smaller Drill Holes Leave a Cleaner Finish
- Cons of Foam Jacking –
- Slightly Higher Material Cost
- Requires Specialized Equipment and Expertise
Foam Jacking vs. Mudjacking in Calgary’s Climate
Calgary’s expansive clay soils and harsh freeze-thaw cycles make concrete repair especially challenging. Water infiltration, erosion, and shifting ground are all common culprits behind sunken concrete.
In this environment, polyurethane foam outperforms traditional slurry. It won’t wash out or shrink over time, and it holds up better under temperature extremes. The lightweight nature of foam is also a major advantage on weak or unstable soils found throughout Calgary.
Environmental and Safety Considerations
When choosing between foam jacking and mudjacking, it’s also important to consider environmental impact and safety. Mudjacking uses a heavy slurry of natural materials, which can sometimes introduce excess water into the soil, potentially causing erosion or further soil instability over time. Conversely, polyurethane foam is chemically inert and expands in a controlled way, minimizing the risk of soil disturbance.
From a safety standpoint, foam jacking involves smaller drill holes and faster curing times, which means less disruption to your property and a quicker return to normal use. This can be especially important for busy commercial sites or homeowners looking to reduce downtime.
Technical Comparison Table
| Feature | Mudjacking | Foam Jacking (Polyurethane) |
| Drill Hole Size | 1″–2″ | ~5/8″ (size of a dime) |
| Material Weight | Heavy (can cause resettling) | Lightweight (won’t overload soil) |
| Cure Time | 24–48 hours | 15–30 minutes |
| Water Resistance | Poor | Excellent |
| Lifespan | 5–10 years | 10–20+ years |
| Precision | Moderate | High |
| Climate Compatibility | Moderate (prone to washout) | Excellent for freeze-thaw cycles |
Which Concrete Lifting Method Is Best?
For a long-term solution with minimal downtime and disruption, polyurethane foam jacking is typically the best option, especially in a city like Calgary where soil conditions can be unpredictable. While mudjacking might appeal for budget-conscious projects, its limitations in durability and water resistance can lead to repeated repairs over time.
