Polyurethane Foam Injection Services

Concrete Lifting & Levelling
Using exclusive, high-density polyurethane foam, we lift and level sunken concrete slabs with precision. This sunken concrete repair method eliminates trip hazards, restores proper drainage, and strengthens the underlying subbase – without the cost and hassle of removal and replacement.
Void Filling & Soil Stabilization
While voids beneath concrete can lead to cracking, sinking, and long-term damage, they can also be a safety hazard. Our void filling process injects foam beneath the slab to fill empty spaces, compact the soil, and stabilize it for years to come, improving the stability and safety of your concrete.
Underslab Insulation
Our underslab insulation process improves energy efficiency by reducing heat loss through your concrete floors. It’s ideal for garages, basements, slab-on-grade homes, warehouse floors, shop floors and agricultural buildings – and it also pairs perfectly with in-floor radiant heating systems.

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.
Common Concrete Problems We Fix:
- Sunken or uneven driveways that cause dips, cracks, and pooling water, making parking and snow removal difficult.
- Trip-hazard sidewalks and walkways where a section has dropped or heaved, creating dangerous lips between sections.
- Settled garage, basement and shop floors that slope toward doors or walls, or in the center, leading to pooling water and surface deterioration.
- Sunken concrete patios, steps, and porches that have pulled away from your home, leaving gaps and poor drainage toward the foundation.
- Void spaces under concrete slabs caused by soil washout, erosion, critters or freeze-thaw cycles, which lead to cracking and further sinking.

Why Choose Polyurethane Over Mud?
- Aesthetically Pleasing: Polyurethane foam requires much smaller injection holes than traditional mudjacking, meaning less visible patch work and a cleaner, more modern repair.
- Prevents Future Settlement: Our concrete repair foams weigh only a fraction of cement-based slurry, so it will not add extra weight that can cause further settlement in weak or saturated soils.
- Longer Lasting Repairs: Foam expands to fill voids, stabilize the base, and lift the slab, curing in as little as 15 minutes from the point of injection, so your concrete is ready for traffic shortly after we finish.
- Less Downtime & Disruption: Most projects are completed in a single visit with no messy demolition, no concrete trucks, and minimal impact on landscaping or operations.
