Concrete Lifting Winnipeg ~ Experts with a 10 Year Warranty!
Slab-Jack Kings™ can lift your sunken concrete for up to 85% less than the cost of removal and replacement!
Dealing with sunken or uneven concrete can be a hassle, but polyurethane concrete lifting is a fantastic, cost-effective alternative to a concrete removal and replacement. It is also a much less invasive and disruptive option compared to traditional mudjacking.
At Slab-Jack Kings, our dedicated technicians are trained experts who bring over 10 years of hands-on experience to carefully raise and restore your sunken concrete. We tailor our specialized geotechnical polyurethane concrete raising foam systems to meet the exact needs of each unique project. We proudly serve all communities in and surrounding Winnipeg, Manitoba.
Our Polyurethane Concrete Lifting Process
1. Concrete Lifting Site Setup & Preparation
On the day of your concrete leveling project, our crew will prepare safe access to your settled concrete. To minimize disruption to your property, our self-contained polyjacking trailer remains parked in one spot, and we simply pull out the exact amount of hose needed to reach the uneven driveway, patio, or sidewalk repair area.
2. Drilling Minimal-Impact Injection Holes
We carefully drill small, 5/8″ injection holes (about the size of a dime) directly into your sunken concrete slab. These precise locations are strategically mapped out to allow the polyurethane foam to travel beneath the slab, targeting the hidden voids causing your concrete to settle in the first place.
3. Precision Concrete Slab Lifting Techniques
To prevent your concrete from fracturing, our expert technicians use a controlled “bunny hopping” method. By moving back and forth between the injection ports, we raise the uneven concrete slab in gentle stages rather than forcing it up all at once. This guarantees comprehensive void filling in the adjacent spaces to ensure proper, long-lasting support.
4. Polyurethane Foam Expansion & Void Filling
Our exclusive polyurethane concrete lifting foam reacts in about 12-15 seconds after injection. As the high-density foam expands under your concrete, it travels up to six feet in diameter to compress weak soils, fill subterranean voids, and lift the slab back into its original position. This creates a highly stable, waterproof new base for your concrete.
5. Post-Lift Patching & Restoration
Once the concrete lifting and levelling is complete and the slab is properly supported, we seal the small injection holes with a fibre-reinforced patching material designed to blend with your existing concrete as it naturally ages. Provided the weather is dry, we can also repair other existing surface cracks or gaps at this time.
6. Fast Curing Time & Project Completion
An average sidewalk or driveway levelling repair takes just 1 to 2 hours, while larger spaces like sinking garage floors or commercial slabs may take most of our workday. Unlike traditional mudjacking that takes days to dry, polyurethane foam cures incredibly quickly. Your newly lifted concrete reaches 90% of its strength in just 15 minutes, meaning it is ready for normal use and heavy vehicular traffic almost immediately after we finish patching!

Frequently Asked Questions
What is concrete lifting?
Is concrete lifting a good idea?
Concrete lifting is often an excellent option when your concrete is still in decent shape but has settled or become uneven.
Why concrete lifting makes sense:
- It is usually much more affordable than tearing out and replacing the slab, so you can solve the problem at a lower cost.
- The work is quick and convenient; many projects are wrapped up in a few hours, and the area can often be used again the same day.
- It removes trip points and slope issues by bringing sunken concrete back to the proper height, improving both safety and appearance.
- The process is low-impact, using small holes and targeted injections instead of major demolition, so surrounding landscaping and structures are largely undisturbed.
- Because it reuses your existing slab instead of sending it to the dump, it’s a more environmentally friendly choice than full replacement.
Does concrete lifting really work?
Yes! Concrete lifting is a highly effective and proven solution for raising and leveling sunken slabs. When performed using polyurethane foam lifting, the results are long-lasting, cost-effective, and environmentally friendly.
What are signs I need concrete lifting?
You’ll usually know it’s time for concrete lifting or levelling when your slabs stop looking level and start causing little annoyances or safety issues.
Common signs to watch for:
- One slab sits lower than the one next to it, creating a noticeable edge or trip hazard along a sidewalk, driveway, patio, or garage floor.
- You can clearly see a section has sunk compared to where it used to be, often a few centimetres or more.
- Water that used to run off now pools on the concrete or drains back toward your house, garage, or steps because the slope has changed.
- Steps, doors, or thresholds feel unusually high because the concrete beside them has dropped.
- The concrete surface itself still looks fairly sound (not crumbling apart), but it’s obviously out of level and seems to be getting worse over time.
- If you’re noticing a few of these at once, it’s a good sign that having the slab lifted and re-leveled is worth looking into.
How long does concrete lifting last?
How expensive is lifting concrete?
Concrete lifting is usually much more affordable than tearing everything out and starting over with brand‑new concrete. In most cases, you’re paying to fix what you already have, not to demolish, haul away, and repour, so the overall bill is lower.
Typical price range:
Polyurethane concrete lifting often falls somewhere in the ballpark of $5–$25 per square foot, depending on the size and complexity of the job.
Because you skip demolition, new concrete and extensive landscaping, homeowners typically save a noticeable amount compared to full replacement for the same area.

Is concrete lifting worth the cost?
Yes, in most cases concrete lifting is absolutely worth the cost. You’re fixing a real problem—like sunken or uneven slabs—without paying for full demolition, disposal, and a brand‑new pour.
For many homeowners, lifting comes in noticeably cheaper than replacement while still giving you a long‑lasting, professional repair. The work is usually done in a few hours, the polyurethane sets quickly, and you can often use the area again the same day, which adds a lot of value in terms of convenience.
Concrete lifting and concrete levelling offers the best bang for your buck when the slab is in decent shape but has settled enough to cause trip hazards or water drainage issues. In those situations, raising what you already have is a smart way to protect your property, improve safety, and extend the life of your concrete without overspending.

What's the best way to lift concrete?
What types of concrete can you lift?
We can lift almost any settled slab-on-grade pour, as long as it is structurally sound.
Typical examples include:
Residential slabs such as driveways, sidewalks, patios, porches, entrance slabs, pool decks, poured steps, garage floors, basement floors and shop floors.
Commercial and agricultural slabs like warehouse floors, barn floors, grain bin pads, and loading areas.

Is concrete lifting better than replacement?
Concrete lifting is usually the better option when your concrete is basically solid but has sunk or shifted out of place. In those situations, you can fix the problem faster, with less disruption, and typically for less money than tearing it all out and starting again.
Lifting tends to shine when you have settled sidewalks, driveways, garage pads, or steps that are uneven or creating trip hazards but aren’t falling apart. In these cases, raising the existing slab back to where it should be lets you keep what you already have, avoid a big demolition mess, and get back to using the area quickly. It’s also a more eco‑friendly choice because you’re reusing the concrete instead of sending it to the landfill.

How much does concrete lifting cost compared to replacement?
In most cases, concrete lifting can be completed for less than half the cost of pouring new concrete. However, the savings can be even greater since the costs associated with demolition, removal, and landscaping are eliminated during the lifting process.
