Concrete leveling is a common repair method used to fix uneven or sunken concrete surfaces. Two popular techniques are polyjacking and mudjacking. Each method has its advantages and is suited for specific situations. Here’s a detailed comparison to help you decide which one is better for your needs.
What is Mudjacking?
Mudjacking, also known as slabjacking, involves pumping a slurry made of sand, cement, and water beneath the sunken concrete. The mixture fills voids and lifts the slab back to its original level.
Pros of Mudjacking:
- Cost-Effective: Typically less expensive than polyjacking.
- Environmentally Friendly: Uses natural materials like sand and cement.
- Proven Method: Has been in use for decades.
Cons of Mudjacking:
- Heavier Material: The slurry is heavier, which can exacerbate underlying soil issues.
- Longer Curing Time: Requires up to 24 hours to set and harden.
- Not Ideal for Small Cracks: May not provide precision for minor repairs.
What is Polyjacking?
Polyjacking uses polyurethane foam to lift and stabilize the concrete. The foam is injected through small holes and expands to fill voids, lifting the slab.
Pros of Polyjacking:
- Lightweight Material: Reduces the risk of soil settling under the weight.
- Quick Setting Time: Foam hardens within minutes, making surfaces usable faster.
- Durability: Polyurethane foam is water-resistant and long-lasting.
- Less Intrusive: Smaller drill holes are used for injection.
Cons of Polyjacking:
- Higher Cost: Typically more expensive than mudjacking.
- Requires Expertise: Needs skilled professionals and specialized equipment.
Key Differences
| Feature | Mudjacking | Polyjacking |
|---|---|---|
| Material | Sand, cement, and water | Polyurethane foam |
| Cost | Lower | Higher |
| Durability | Moderate | High |
| Setting Time | Up to 24 hours | A few minutes |
| Application | Large, non-critical areas | Precision for all projects |
Concrete Leveling Repair
- Assessment: Inspect the concrete surface for cracks, settlement, and voids. Determine the cause, such as soil erosion or poor compaction.
- Choose the Right Method: Consider the area size, budget, and urgency.
- Hire Professionals: Both methods require skilled technicians to ensure accurate leveling.
- Prevent Future Issues: Address underlying soil or drainage problems to prevent recurring damage.

FAQs About Polyjacking and Mudjacking
1. Is polyjacking more durable than mudjacking?
Yes, polyurethane foam used in polyjacking is resistant to moisture, erosion, and wear, making it more durable in most cases.
2. Can I use these methods for residential repairs?
Both methods are suitable for residential and commercial properties. Polyjacking is preferred for precision repairs in driveways, sidewalks, and patios.
3. How long does each process take?
Mudjacking may take up to a day to cure, while polyjacking allows you to use the surface within 30 minutes.
4. Which method is more cost-effective?
Mudjacking is generally cheaper upfront, but polyjacking offers better long-term value due to its durability.
5. Can I DIY concrete leveling?
Concrete leveling requires specialized tools and expertise, so hiring professionals is recommended for both methods.
Conclusion
If you’re on a budget and working on non-critical areas, mudjacking may suffice. For a faster, more durable, and less intrusive solution, polyjacking is the better choice despite its higher cost. Always consult a professional to assess your specific needs and ensure a long-lasting repair.
