Concrete surfaces don’t stay perfect forever. Over time, sidewalks, driveways, patios, and even foundations can sink or become uneven due to soil erosion, moisture changes, or poor compaction. When this happens, property owners often face a decision: replace the concrete entirely or opt for a more cost-effective solution—concrete jacking.
In this comprehensive guide, we’ll cover everything you need to know about the process, how it works, the benefits, costs involved, and whether it’s truly worth your investment.
What Is Concrete Jacking?
Concrete jacking, also known as slab jacking or mudjacking, is a process that lifts sunken or uneven concrete back to its original position. Instead of tearing out the damaged slab, a specialized mixture—usually cement, soil, sand, and water—is injected underneath to raise the slab.
This technique is commonly used for house leveling, driveway repairs, patios, garage floors, and even interior concrete slabs. It’s a minimally invasive method that’s faster and more affordable than full replacement.
How Does Concrete Jacking Work?
The process begins by drilling small holes in the affected concrete slab. A lifting compound is then pumped under pressure beneath the slab. As the material fills the voids and compresses the soil, the slab gradually lifts back into place.
This method is commonly used in Concrete Slab Foundation Repair to restore structural integrity without full replacement. After leveling, the holes are patched, and the area is cleaned up. The entire procedure usually takes a few hours and the surface can be used within 24 hours.
Benefits of Concrete Jacking
- Cost-Effective: It typically costs 30-50% less than replacing concrete.
- Quick Turnaround: Most jobs are completed in a single day.
- Non-Invasive: No heavy demolition or hauling of broken concrete.
- Environmentally Friendly: Reuses existing materials instead of dumping slabs into landfills.
- Restores Functionality: Eliminates trip hazards and restores visual appeal.
Concrete Jacking vs. Replacement: Which Is Better?
Concrete replacement is necessary when slabs are severely cracked, crumbling, or structurally compromised. However, if the surface is in good condition but simply uneven or sunken, alternative leveling methods are often the smarter choice.
For instance, pier & beam foundation repair often involves much more extensive and costly structural work, while concrete jacking focuses on surface-level correction and stabilization. The two solutions address different issues, but jacking is ideal for cosmetic and light structural corrections.

When Should You Consider Concrete Jacking?
Concrete jacking is ideal in the following scenarios:
- Sidewalks or driveways have sunken in sections
- Garage or basement floors are uneven
- Patios or pool decks are sloped or cracked due to settling
- Minor foundation settling without major structural damage
It’s important to address these issues early. Uneven concrete can lead to water drainage problems, tripping hazards, and even more significant foundation concerns down the line.
Cost of Concrete Jacking in 2025
The average cost for concrete jacking ranges from $5 to $25 per square foot, depending on:
- Size of the area
- Depth of settlement
- Accessibility of the site
- Type of material used (traditional mudjacking vs. polyurethane foam)
While the upfront cost is lower than full replacement, it’s also worth noting that polyurethane foam lifting tends to be more expensive but provides longer-lasting results and less mess.
Is Concrete Jacking a Long-Term Fix?
In most cases, yes. When done correctly by professionals, concrete jacking can last 8 to 15 years, or even longer. Proper soil stabilization and drainage improvements can extend the life of the repair.
That said, the longevity also depends on the cause of the initial settlement. If poor drainage or expansive soil remains unaddressed, future sinking is possible.
Concrete leveling through jacking is not a one-size-fits-all solution. It’s crucial to diagnose the underlying cause of the issue to determine the best method for long-term stability.
Choosing the Right Contractor
Not all contractors are equal when it comes to fixing house foundation issues or lifting concrete slabs. Look for licensed professionals with experience in concrete repair. Ask about warranty options, the materials they use, and their repair process.
Avoid going for the cheapest bid—quality materials and expert execution will save you money in the long run.
Conclusion
Absolutely—concrete jacking offers a fast, cost-effective, and minimally disruptive solution for uneven concrete surfaces. If your slab is structurally sound but uneven or sunken, jacking can restore both form and function without the hassle of full replacement.
It also enhances curb appeal, improves safety, and helps preserve property value. While not suitable for every situation, it’s often the best fix for common concrete issues. Whether you’re managing minor sidewalk damage or considering larger repairs for pier & beam foundation repair, jacking is worth exploring with a trusted contractor.
If you’re dealing with sinking concrete around your home, it’s time to consider concrete leveling before the problem worsens. Investing in concrete jacking now could save you thousands in future repairs.
FAQS (Frequently Asked Questions)
1. How long does concrete jacking last?
Concrete jacking typically lasts 8–15 years, depending on soil conditions, weather, and drainage.
2.Is it safe to use alternative methods for foundation repair?
Yes, for minor foundation leveling. However, for serious structural problems, a full foundation evaluation is recommended.
3. Can I do concrete jacking myself?
It’s not advisable. The process requires professional tools and expertise to ensure the concrete lifts evenly and stays stable.
4. How soon can I use the area after jacking?
Most surfaces are ready for light use within hours and full use within 24 hours.
5. Does this method work on all types of concrete?
It’s most effective on solid, intact slabs that have sunken. Severely cracked or crumbling concrete may need replacement.
