Mudjacking is a widely used concrete repair method for lifting and stabilizing sunken slabs, but property owners often ask: How long will mudjacking last? The durability of mudjacking depends on various factors, including soil conditions, the quality of materials used, and proper maintenance. Understanding its expected lifespan, signs that indicate reapplication is needed, and ways to extend its effectiveness can help you make an informed decision about your concrete repair needs.

What is Mudjacking in Construction?
Mudjacking, also known as slab jacking or concrete lifting, is a repair technique used to raise sunken or uneven concrete surfaces. This process involves drilling small holes into the affected slab and injecting a slurry mixture—typically composed of cement, soil, sand, and water—beneath it. The injected material fills voids and lifts the slab back to its original level, restoring stability and functionality. Commonly used for sidewalks, driveways, patios, and foundations, mudjacking is a cost-effective alternative to full slab replacement. However, its effectiveness depends on factors such as underlying soil conditions and the quality of the repair process.
Factors Affecting the Lifespan of Mudjacking
The longevity of mudjacking isn’t the same for every project—it can last anywhere from a few years to over a decade, depending on several key factors. Here’s what influences how long your mudjacked concrete will stay level and stable:
Soil Conditions Beneath the Concrete
The type of soil beneath your concrete plays a crucial role. Expansive clay soils, for example, are prone to shrinking and swelling with changes in moisture content, which can lead to further settling or shifting of the concrete.
Stable, well-compacted soil provides a more solid foundation and contributes to longer-lasting results. If you live in an area with challenging soil conditions, it’s essential to discuss this with your mudjacking contractor. They can often recommend solutions like adding stabilizing materials to the slurry mix to improve the longevity of the repair.
Water Drainage Around the Area
Water is one of the biggest threats to concrete stability. If rainwater or runoff consistently flows beneath the slab, it can wash away the supporting material, causing the concrete to sink again. Proper drainage solutions, such as gutters and sloped landscaping, can help prevent this issue.
Traffic and Load
Heavy loads and frequent traffic can speed up wear and tear. A mudjacked driveway that supports large vehicles daily will likely need repairs sooner than a lightly used patio or walkway.
Climate and Weather Conditions
In places with harsh winters—like many parts of Canada—freeze-thaw cycles can impact concrete longevity. When water seeps into small cracks and freezes, it expands, creating pressure that can weaken the slab over time. Proper sealing and maintenance can help reduce this risk.
Quality of the Mudjacking Materials
The quality of the slurry mixture used in the mudjacking process directly impacts its durability. A well-mixed slurry with the appropriate proportions of cement, soil, sand, and water will create a stronger and more stable base. Don’t hesitate to ask your contractor about the materials they use and their experience with different slurry mixes.
Proper Installation by Experienced Professionals
Even the best materials won’t last if the job isn’t done right. Skilled professionals know how to assess soil conditions, use the right mixture, and inject it correctly to provide a stable and durable result. Poorly executed mudjacking can lead to uneven lifting, weak spots, and a shorter lifespan.
How Long Will Mudjacking Last? (Expected Durability)
Mudjacking typically lasts 5 to 10 years, depending on factors like soil stability, drainage, and weather conditions. In ideal conditions with proper maintenance, it can last even longer.
What Affects Mudjacking Longevity?
- Stable Soil & Good Drainage: Can extend lifespan beyond 10 years.
- Weak Soil & Poor Drainage: May require repairs within 1–5 years.
- Harsh Weather (Freeze-Thaw Cycles): Can cause quicker deterioration.
- Heavy Traffic: Driveways and high-use areas may wear out faster.
How It Compares to Other Methods
- Mudjacking: 5–10 years (affordable but not permanent).
- Polyurethane Foam Lifting: 10–20 years (more durable, water-resistant).
- Full Concrete Replacement: 25+ years (expensive but long-term solution).
Mudjacking is a reliable, cost-effective fix for sunken concrete, but regular maintenance is key to maximizing its lifespan. Next, we’ll cover the signs that indicate when your concrete may need mudjacking again.
Signs Your Concrete Needs Mudjacking Again
Over time, concrete may settle again due to soil movement, weather, or water damage. Watch for these signs:
- Uneven or Sunken Slabs – If concrete starts sinking or feels unstable, the soil underneath may have shifted.
- Cracks Reappearing – Widening or spreading cracks indicate ongoing settling.
- Water Pooling – Puddles on your concrete suggest improper leveling and drainage issues.
- Doors or Garage Misaligned – If they don’t close properly, shifting concrete could be the cause.
- Trip Hazards – Raised edges between slabs create safety risks and signal the need for repairs.
Catching these signs early can prevent bigger issues. Next, we’ll cover how to extend the lifespan of mudjacking repairs.
Tips to Extend the Lifespan of Mudjacking Repairs
Proper maintenance can help your mudjacking repair last longer. Follow these key tips to keep your concrete stable:
- Improve drainage – Redirect water away from concrete with gutters, downspouts, and sloped landscaping to prevent soil erosion.
- Seal cracks & joints – Use a concrete sealant to keep water from seeping in and weakening the base. Applying a high-quality concrete sealant annually can protect the surface from water absorption and extend its durability.
- Avoid heavy loads – Minimize parking heavy vehicles or equipment on repaired slabs to reduce stress. If the area will experience significant weight loads, adding support structures like piers or additional reinforcements can help.
- Monitor for early signs of settling – Check for minor sinking, cracks, or pooling water and address issues promptly.
- Regular inspection and maintenance – Regular inspections and minor touch-ups can prevent larger repairs down the line.
Taking these steps will help maximize the durability of your mudjacking repair, keeping your concrete level and safe for years to come.
Conclusion
So, how long will mudjacking last? The answer depends on several factors, including soil stability, drainage, weather conditions, and maintenance. While mudjacking typically lasts between 5 to 10 years, proper care can help extend its lifespan. Keeping an eye out for early signs of settling and addressing drainage issues can make a significant difference in maintaining your concrete’s stability.
