Uneven concrete around your property is more than just an eyesore; it can be a safety hazard and potentially lower the value of your home. Particularly common in older homes or those built on shifting soil, uneven surfaces can lead to tripping accidents, drainage problems, and even structural damage over time. Fortunately, concrete leveling offers a solution, restoring surfaces to their original position or as close as possible, usually within just a few hours.
Mudjacking: The Traditional Method Of Concrete Leveling
Mudjacking is the old-school method of concrete leveling. It has been widely used for years because it’s effective and efficient. This process involves drilling small holes about the size of a tennis ball into the sunken concrete slab and injecting a specialized mixture of water, cement, and soil under high pressure.
How Mudjacking Works
- Drill Holes: Small, strategically placed holes, typically about one inch in diameter, are drilled into the affected area of the concrete slab.
- Inject Slurry: The thick slurry is pumped under the slab. It fills any voids beneath the slab and exerts upward pressure, lifting the concrete back to its proper elevation.
- Seal Holes: Once the slab is level, the holes are sealed with a concrete patch or a similar material, ensuring a smooth, seamless finish that blends with the surrounding area.
Limitations Of Mudjacking
- Weight: The slurry is heavy and might not be suitable for all soil conditions. Evaluating the underlying soil is crucial to ensure it can support the added weight without further settling.
- Settling: The material used in mudjacking can erode or settle over time, especially in areas with frequent water exposure or poor drainage, potentially leading to a return of the original problem.
- Precision: Due to the slurry’s characteristics, achieving precise leveling can be challenging, which may lead to necessary readjustments in the future.
While mudjacking is an effective solution for leveling concrete slabs, it requires careful consideration of the site conditions and ongoing maintenance to ensure lasting results.
Polyurethane Foam Injection: How Concrete Leveling Is Done Today
A newer and increasingly popular technique, polyurethane foam injection, offers a more advanced approach to concrete leveling. This method uses high-density foam to lift concrete slabs with minimal disruption.
Benefits Of Polyurethane Foam Injection
- Lightweight: Polyurethane foam is significantly lighter than the traditional mudjacking slurry, which helps to reduce the risk of further settling and damage to the underlying soil. This characteristic makes it an ideal choice for various applications, especially in areas where weight is a concern.
- Quick Curing Time: One of the standout features of polyurethane foam is its rapid curing time. It sets within minutes, allowing for immediate use of the surfaces, which minimizes downtime and disruption to daily activities. This makes it particularly advantageous for commercial properties that require quick turnarounds.
- Precision and Durability: Polyurethane foam offers more precise leveling than mudjacking. Additionally, the foam is designed for long-term durability, being resistant to water erosion, temperature fluctuations, and other environmental factors that can compromise the integrity of traditional materials.
How It Works
- Drill Holes: Small, strategically placed, dime-sized holes are carefully drilled into the concrete slab.
- Inject Foam: Polyurethane foam is injected through these holes. As it enters the voids underneath the slab, the foam expands rapidly, exerting pressure that lifts it to its desired position.
- Seal Holes: Once the lifting process is complete, the holes are filled with a matching concrete patch. This not only restores the surface’s aesthetic but also ensures a seamless finish that blends well with the existing concrete.
Mudjacking Vs. Polyjacking
When considering concrete leveling, weighing your options based on cost, durability, and process is essential.
Mudjacking may be cost-effective for some homeowners, but polyurethane foam injection offers superior precision and longevity, making it a worthwhile investment for lasting results.

Preventing Uneven Concrete Surfaces
Maintaining concrete surfaces such as sidewalks, driveways, and patios requires proactive measures to prevent uneven settling and damage over time. Here are some strategies to help maintain smooth, level concrete areas:
Regular Maintenance And Inspection
Conduct regular inspections to identify any early signs of cracking or settling. Address minor issues promptly to prevent them from turning into significant problems. Look for any visible shifts or water pooling, which can indicate underlying issues.
Proper Drainage Systems
Ensure your property has adequate drainage systems to direct water away from concrete surfaces. Water accumulation is one of the primary causes of soil erosion and concrete settling. Use gutters, downspout extensions, and grading techniques to manage water flow effectively.
Seal The Concrete
Apply a high-quality concrete sealant periodically to protect the surface from water penetration, freeze-thaw cycles, and chemical exposure. Sealing the concrete can help extend its lifespan and reduce the risk of cracking.
Tree Root Management
Plant trees away from concrete surfaces; tree roots can cause significant upheaval as they grow. Consider root barriers or consult an arborist for appropriate tree root management strategies if trees are already present.
Soil Compaction
During initial construction, ensure proper soil compaction underneath your concrete surfaces. Poorly compacted soil can lead to uneven settling over time. If necessary, enhance soil stability with appropriate additives or reinforcing materials.
Implementing these preventative measures can prolong the life of your concrete surfaces and minimize the likelihood of uneven settling and necessary repairs. Regular attention and maintenance are key to ensuring durable and aesthetically pleasing concrete areas around your property.
Addressing uneven concrete surfaces is crucial for maintaining your home’s safety and value. While mudjacking and polyurethane foam injection have their places in concrete leveling, the choice ultimately depends on your specific needs, budget, and long-term goals.
Understanding the benefits and limitations of each method is essential for homeowners to make an informed decision. If you’re unsure which option is best for your home, consider contacting a professional for an assessment.
