Uneven or sunken concrete isn’t just an eyesore—it can also be a safety hazard and a sign of deeper foundation issues. Whether it’s your driveway, patio, sidewalk, or garage floor, sinking concrete can happen over time due to soil erosion, poor compaction, or water damage. Fortunately, concrete lifting services offer an effective and affordable solution to restore your concrete surfaces without needing full replacement.
In this post, we’ll explore how concrete lifting works, its benefits, and what you should know before hiring a professional.
What Is Concrete Lifting?
Concrete lifting—also known as slab jacking, mudjacking, or polyjacking—is a repair process used to raise and level sunken or uneven concrete slabs. Instead of tearing out and replacing the slab, technicians inject specialized materials beneath it to fill voids and lift the concrete back to its original level.
There are two main methods used today:
- Mudjacking:
A traditional method that pumps a slurry mixture (made of water, soil, sand, and cement) beneath the concrete slab. The pressure lifts the slab back into place. - Polyurethane Foam Injection (Polyjacking):
A more modern technique using lightweight, high-density polyurethane foam that expands underneath the slab to raise and stabilize it. Polyjacking is cleaner, faster, and more durable than traditional mudjacking.
Benefits of Concrete Lifting Services
1. Cost-Effective
Concrete lifting costs significantly less than removing and replacing entire slabs. In most cases, you can save 50–70% compared to replacement.
2. Quick and Convenient
Most concrete lifting jobs can be completed in just a few hours, and you can use the surface again almost immediately after the repair.
3. Minimal Disruption
Since the process involves drilling small holes instead of demolishing the slab, it’s far less messy and disruptive.
4. Environmentally Friendly
Polyurethane foam and mudjacking materials use existing concrete, reducing waste and conserving resources.
5. Long-Lasting Results
When done properly by professionals, lifted concrete can last for years—often matching the lifespan of the original installation.
When Should You Consider Concrete Lifting?
You may need concrete lifting if you notice:
- Uneven or sloping slabs
- Cracks in your driveway, sidewalk, or patio
- Water pooling on concrete surfaces
- Gaps between concrete and adjoining structures
- Doors or garage openings that don’t align properly
Addressing these issues early can prevent more costly foundation or structural problems down the road.
The Concrete Lifting Process: Step-by-Step
- Inspection:
A technician evaluates the affected area to determine the cause and best repair method. - Drilling Small Holes:
Small holes (about the size of a dime) are drilled in strategic spots on the slab. - Injection:
The lifting material (slurry or foam) is injected beneath the slab, filling voids and raising it to the correct level. - Sealing:
Once lifted, the holes are patched with durable concrete to blend seamlessly with the surrounding surface. - Clean-Up and Use:
The area is cleaned, and the concrete is ready for use within hours.
FAQs About Concrete Lifting Services
1. How long does concrete lifting take?
Most residential jobs take just a few hours. Larger or commercial projects may take longer depending on the size and complexity.
2. Is concrete lifting permanent?
While not always “permanent,” professional lifting can last for decades if the underlying soil remains stable and drainage issues are addressed.
3. Can all concrete be lifted?
Not always. Severely damaged, crumbling, or structurally compromised concrete may require replacement instead of lifting.
4. Is polyjacking better than mudjacking?
Polyjacking is generally more precise, lighter, and longer-lasting than traditional mudjacking, though it can cost a bit more upfront.
5. How much does concrete lifting cost?
Costs vary depending on area size, location, and material used. On average, homeowners spend between $5 to $25 per square foot, much less than full replacement.
6. How soon can I use my concrete after lifting?
With polyurethane foam injection, you can usually use the surface within 15–30 minutes after the job is complete. Mudjacking may require up to 24 hours of curing time.
Final Thoughts
Concrete lifting is an excellent solution for homeowners and property managers looking to restore the safety, appearance, and function of their concrete surfaces—without the high costs and mess of replacement.
If you’re seeing signs of sinking or uneven slabs, don’t wait—contact a professional concrete lifting company to assess your property and recommend the best repair option.
