Concrete Lifting & Levelling
Dealing with sunken or uneven concrete can be a hassle, but polyurethane concrete lifting and levelling 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 lift and restore your sunken concrete. We tailor our specialized geotechnical polyurethane concrete raising systems to meet the exact needs of each unique project. We proudly serve most communities across Manitoba & Northwestern Ontario. Please take a moment to check out our Service Areas page to confirm if we can help bring your concrete back to life.
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.
The Polyurethane Concrete Lifting Process
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!

Whether you need to fix an uneven residential driveway or require heavy-duty industrial concrete raising, our expanding technology delivers a durable, waterproof repair.

Manitoba’s Best-Reviewed Experts in Concrete Lifting
The slab is level and looks great! I’m hoping it stays level for years to come.
From the initial inquiry to get an estimate back in February where they reached out promptly to let me know I’m in their queue once the ground was ready for inspection. To when Tim and his wife came out to provide their estimate and explained in great detail their process and how they started their family run business. To Amy coordinate the scheduling to get the job done and finally to Chris and his crew doing the actual work and explaining their process as they were doing the work and not to mention how they cleaned up nicely post work. Oh and the digital process they used for issuing the agreement and payment options which was very convenient!
I got estimates from 3 other slab jacking local companies that uses polyurethane and Slab Jack Kings by far resonated with me most! The other two just seemed not very interested in convincing me why I need to go with them and to me this is important.
Now regarding the traditional “mud jacking vs polyurethane foam”… Well my neighbour got his driveway lifted last summer with that famous Winnipeg mud jackers” and it’s already sunk about 3/4 of an inch. Sure it’s more cost effective but that was not for me.
I have friends and co-workers who recommended going with polyurethane foam and all 4 of them have said their driveway has not dropped much at all. One of them said they’re dropped maybe 1/4 of an inch and has held up for the last 6 years.
Oh one more thing. Of the companies I looked into for polyurethane lifting, Slab Jack Kings had the longest warranty term of 10 years. I value that as well!
Thanks again Slab Jack Kings!!!
Our small town had lots of supervisors when this truck, trailer and crew showed up. The guys were friendly and answered ALL of their questions. I wld recommend Slab Jack Kings to anyone needing a driveway lift.
Thanks to Tim also, showed up to measure and provide quote. All other companies were just asking for pics and provided estimates. Tim from Slab Jack Kings showed up...and that is worth alot right there.
Thx guys!
The Stinsons
Slab-Jack Kings helped me to pump for settling in 2020 which was four years ago.
This year, I contacted them and they told me that my situation is still covered by the warranty. Today they get the work done with quick and professional manner. I really appreciate to work with honest company like them. I will definitely ask help from they if there are something wrong with my basement again in the future.
For my project, foam jacking was the best option: it was faster, less invasive, and much cheaper than mud-jacking or replacing the whole slab.
I'd definitely recommend this company if you have a slab or sidewalk or something that's off kilter. Everyone I dealt with was excellent and all aspects of the project were clearly communicated.
Thanks!
Chris and Jeremy arrived on time, and were very professional. Chris verified the work with my husband Jeff before starting. They did a fantastic job of leveling our patio and sunroom pad, raising it over 3 inches in one area. Cleanup was exceptional, no mess left.
Would definitely recommend this company!
4 years ago: Chris did a good job setting expectations and advising me of the jacking process. He completed the job only about a month after the estimate, and at the quoted price.
I did a bit of research before going with foam jacking over mud jacking. A couple of the reasons I went with foam jacking were weight, strength and durability. I would recommend Slab Jack Kings.
They advised us throughout the process of what would happen doing a lift of 7 inches. When the floor of our attached garage presented with some unforeseen circumstances, they advised us of the issues and presented options for us to choose from. The before and after photos were great to receive.
We would have no hesitation to refer our friends and family to Slab-Jack kings for the concrete lift jobs.
The work itself was great. I can hardly see the holes that were drilled to inject the urethane mix.
Finally after only three days, several of my neighbours have come by to look at the job and are interested in contacting this company for more information.
A fine family owned Manitoba company.
