Beachside Path Leveling & Protection

2026-01-15T09:45:19.05Z

estoring this walkway required a two-part strategy: to level the path and protect it against Wasaga Beach’s unique climate. First, our team employed a precision hydraulic lifting technique to raise the sunken slabs. Each lift was carefully monitored to ensure smooth, flush transitions—from the driveway to the walkway and up to the front porch. This immediately eliminated trip hazards and restored proper pitch, allowing water to shed off the sides rather than pooling in the center.

Once the walkway was level, we treated every seam with our Premium Crack and Joint Sealant. In a sandy, shifting environment, this sealant provides a crucial flexible, watertight barrier. By sealing both the joints between the slabs and the edges along the brickwork, we prevented water from reaching the sub-base, stopping the cycle of erosion and locking the slabs securely in their newly leveled position.

Walkway Realignment and Sub-base Stabilization

2026-01-13T15:31:55.05Z

To address the failure without the cost and mess of a full demolition, the chosen solution was a sophisticated process known as polyurethane injection. This method targeted the root cause—the hollow space beneath the concrete—by using the slab itself as a bridge. Technicians began by drilling several small, penny-sized holes through the surface of the sunken walkway.

Through these ports, they injected a specialized, high-density structural polymer into the underlying cavity. As the two-part liquid material reacted, it underwent a powerful chemical expansion. This expansion filled the pockets of air and compacted the loose soil into a stabilized, load-bearing base.

The force of this reaction provided the necessary hydraulic lift to move the massive slab back up the three inches required to meet the landing. By carefully controlling the injection points, the team was able to "jack" the concrete back into alignment with the step and the brickwork, restoring the proper transition between surfaces. Once the lift was complete, the drill holes were patched with a concrete grout to blend in with the surrounding surface. The result was a stabilized walkway that was once again safe for use and supported by a waterproof foundation designed to resist the specific soil erosion issues found in the Beaverton area.

Thornbury Triple-Threat

2026-01-13T10:05:14.05Z

When the homeowners called Canadian Concrete Leveling, we knew we could save their investment. Instead of bringing in heavy machinery for a full tear-out, we took a more surgical approach. Walking the property with the owners, we identified the exact spots where the soil had failed.

Using our specialized polyurethane injection system, we went to work. Through tiny, penny-sized holes, we injected high-density leveling material deep underground, filling the voids and slowly lifting the massive stamped slabs back into place. Soon, the slabs sat perfectly flush with the natural stone borders once again.

By the end of the afternoon, the trip hazards were gone, and the backyard drainage was fully restored. We returned the homeowners’ safety, curb appeal, and peace of mind—without moving a single plant or disturbing a single stone. They were thrilled to have a level, beautiful yard again, all without the chaos of a traditional construction project.

Concrete Pool Deck Stabilization

2026-01-09T13:50:42.05Z

Canadian Concrete Leveling addressed the problem with a targeted concrete stabilization method specifically designed for poolside environments. Our team began by assessing the settled areas, measuring elevation differences, and identifying the soil voids beneath the slabs.

High-density polyurethane foam was then carefully injected beneath the affected concrete. As the foam expanded, it filled voids, lifted the slabs back into proper alignment, and compacted the underlying soil to provide long-term support. Injection points were strategically placed to maximize efficiency and minimize surface disruption, preserving the appearance of the deck and the surrounding landscaping.

The results were immediate and impactful. The pool deck was restored to a level, stable surface, eliminating trip hazards and improving water drainage. The homeowners were able to enjoy their backyard right away, without the disruption of demolition or extensive cleanup. By using polyurethane injection, they avoided a costly full deck replacement while extending the life of their concrete and protecting their investment in both safety and aesthetics.

The East York Slope Correction

2026-01-08T14:18:46.05Z

In East York, narrow side-lots are a common urban feature, and the concrete walkways that run alongside homes often serve a dual purpose: providing safe pedestrian access and acting as critical drainage channels for the property. In this case, the homeowner observed significant settlement of their side-lot walkway toward the house, creating a “negative pitch.” This condition caused rainwater to flow directly against the brickwork, increasing the risk of water seepage and long-term moisture damage to the foundation.

The settlement also created a notable trip hazard and disrupted the alignment of the existing downspout extensions, further exacerbating drainage issues. Conventional repair methods, such as complete removal and replacement of the concrete, were considered impractical due to several constraints: the narrow workspace prevented the use of heavy machinery, and excavation would risk disturbing adjacent landscaping while incurring high labor and material costs.

Safe, Level, and Durable: Restoring a Commercial Sidewalk

2026-01-07T13:45:45.05Z

Canadian Concrete Leveling addressed these issues using a high-density geotechnical polymer injection process. Small, non-invasive injection points allowed the team to fill the underlying voids and lift the slabs back toward their original position. This process eliminated tripping hazards while restoring a uniform and level appearance to the sidewalk.

After stabilization, a premium-grade crack and joint sealant was applied along the gap between the sidewalk and the building’s exterior. This durable, flexible, and waterproof seal prevents water from penetrating the sub-base, halting the cycle of erosion and protecting the walkway from future settlement.

The project restored a safe, visually appealing walkway while minimizing disruption to the business’s daily operations. The combined approach of polymer injection and protective sealing ensures long-term stability and enhanced resistance to the elements, providing peace of mind for property owners and a safer environment for all visitors.

Leveling the Ground: How We Solved Severe Driveway Settlement

2026-01-05T13:57:50.05Z

Our team used a high-density polyurethane injection system to lift and stabilize the settled concrete without demolition. Small access holes were drilled in the affected slabs, allowing the material to flow into the voids beneath the driveway and garage floor. This re-compacted the subgrade and provided precise hydraulic lift, restoring the slabs to their original elevation and eliminating trip hazards.

Next, we applied our Premium Crack and Joint Sealant to seal the cracks and expansion joint, creating a watertight barrier to prevent soil erosion and future water damage. Because the polyurethane cures within minutes, the driveway was ready for immediate use.

By choosing concrete lifting and professional sealing over full replacement, the homeowner achieved a safe, level surface quickly and at a fraction of the cost. The repair was minimally disruptive, highly effective, and provides a long-lasting solution that protects both the driveway and the home’s foundation.

Correcting Sub-Slab Erosion Beneath a Garage Floor

2025-12-30T11:32:20.05Z

Our inspection confirmed that the slab failure was caused by sub-surface erosion and inadequate soil compaction beneath the garage floor. Rather than removing the slab, our team recommended a non-invasive repair using the PolyLevel® System.

Small, dime-sized injection holes were drilled through the concrete, allowing a high-density two part polyurethane to be injected directly into the voids beneath the slab. As the foam expanded, it migrated through the compromised soil, filling empty spaces and re-establishing uniform support. The controlled expansion provided precise hydraulic lift, raising the slab back to its original elevation and closing the gap along the foundation wall.

Once the slab was stabilized, Premium Crack and Joint Sealant was applied to the remaining fractures. This UV-resistant, flexible material creates a long-term waterproof seal designed to move with the concrete through Alliston’s seasonal freeze-thaw cycles.

The entire repair was completed in a single day, restoring structural stability to the garage floor without demolition, downtime, or disruption — and giving the homeowner a long-term solution they could trust.

Commercial Trip Hazard Mitigation

2025-12-22T14:03:39.05Z

Our team addressed the issue using a high-density polyurethane injection system designed to lift and stabilize settled concrete without demolition. Small, discreet access holes were drilled into the affected slab, allowing the repair to be completed without heavy equipment or disruption to the surrounding area.

Once injected, the expanding polyurethane foam flowed into the voids beneath the sidewalk, re-compacting the weakened subgrade and delivering precise, controlled hydraulic lift. The slab was carefully raised back to its original elevation, restoring a smooth, flush walking surface that eliminated the trip hazard entirely.

Because the polyurethane reaches near-full strength within minutes, the sidewalk was reopened to pedestrian traffic immediately after the repair. The entrance was restored to a safe, level, and professional condition with zero downtime for nearby businesses. By choosing concrete lifting over full replacement, the client avoided the complications of a construction zone while achieving a long-lasting repair at a fraction of the cost.

Lifting and Sealing for Lasting Protection

2025-12-19T10:16:24.05Z

Canadian Concrete Leveling implemented a comprehensive two-step restoration plan designed to address both the immediate hazards and the long-term durability of the property. The first step involved lifting and leveling the concrete using high-density polyurethane foam. Our team carefully injected the foam beneath the sunken slabs through small, strategic entry points. As the foam expanded, it filled the voids beneath the concrete and lifted each section back to its original height. The result was instant: the walkways became smooth, level, and safe, with the tripping hazards completely eliminated. This process not only corrected the visible issues but also reinforced the ground beneath the slabs, reducing the risk of future settling.

After leveling, we focused on protecting the property against future damage. We applied premium crack and joint sealant along the perimeter where the walkways met the foundation, creating a flexible, watertight barrier to prevent water from seeping through and causing erosion or basement dampness. The control joints across the back patio were also treated, safeguarding the concrete against Ontario’s harsh freeze-thaw cycles and preventing weeds from growing in the cracks. This thorough approach ensured that the repaired walkways would remain stable, durable, and low-maintenance for years to come.

Results:
The transformation was remarkable. The walkways are now fully stabilized, safe, and visually seamless, complementing the home’s exterior beautifully. More importantly, the homeowners gained peace of mind, knowing that their foundation is protected and the concrete will hold up for years to come. This project demonstrates the value of professional concrete leveling—not just as a cosmetic fix, but as a smart, long-term investment in safety, stability, and durability.

Seamless Strength: Solving Concrete Cracks with Precision

2025-12-11T15:48:14.05Z

Our team approached the project with precision and care, using our premium crack and joint sealant system to address the underlying issue and provide a durable, flexible solution. Preparation was key: each crack and joint was meticulously cleaned to remove dirt, debris, and any old sealant, ensuring optimal adhesion and long-term performance. For deeper gaps, we inserted backer rods to control sealant depth and allow the concrete to expand and contract naturally, preventing future cracking.

Once the areas were prepped, our high-performance, flexible sealant was injected into every joint and crack. This created a continuous, seamless barrier that fully protected the underlying soil from water intrusion. The result was a smooth, professional-grade finish that not only enhanced the concrete’s appearance but also restored its stability and durability.

By carefully addressing both the visible cracks and the hidden structural issues, we delivered a solution that protects the property from future damage while maintaining its aesthetic appeal. The client now has a concrete surface that is strong, safe, and visually seamless, with lasting protection against the effects of water and erosion. This project demonstrates how proactive maintenance and expert application of the right materials can extend the life of exterior concrete surfaces, saving time and money in the long run.

From Trip Hazards to Safe Paths: Milton Community Walkway Restoration

2025-12-10T10:58:10.05Z

Canadian Concrete Leveling provided a modern, efficient solution that addressed the root of the problem without resorting to full-scale construction. The team began by carefully assessing the walkways to identify which slabs were sunken and where the soil had eroded beneath them.

Technicians then drilled small, dime-sized holes into each affected slab, creating precise access points for the lifting process. Through these holes, a specialized, lightweight structural compound was injected beneath the concrete. This material flowed into the empty pockets and weak soil, expanding gently to fill voids and firm up the ground. The expansion was carefully controlled to lift the slabs smoothly, returning them to a level position with neighboring sections while eliminating all tripping hazards.

The process was clean and minimally invasive: there was no digging, no heavy equipment, and no large-scale disruption for residents. Because the compound hardens almost instantly, the walkways were safe to use immediately after treatment. The community now enjoyed smooth, stable paths that provided long-term safety, improved accessibility, and peace of mind—all at a fraction of the cost and time compared to traditional concrete replacement.

Results
The intervention by Canadian Concrete Leveling delivered immediate and long-lasting benefits for the Milton community:

Safe, Level Walkways: All previously sunken and uneven slabs were restored to a smooth, stable surface, removing tripping hazards and improving safety for residents of all ages.
Immediate Accessibility: Walkways were usable right after treatment, meaning residents could continue their daily routines without delays or disruptions.
Cost and Time Savings: The project avoided the significant expense, extended timeline, and disruption associated with full concrete replacement, providing a high-value solution.
Durable, Long-Term Solution: The injected structural compound stabilized the soil beneath the slabs, ensuring that the walkways remain level and safe for years to come.
Minimal Disruption: The process was clean, quiet, and efficient, allowing the community to maintain normal activity during the repairs.

Overall, the project transformed the walkways into safe, accessible paths while saving the community significant time, money, and stress—demonstrating how modern concrete leveling techniques can offer smarter alternatives to traditional replacement methods.

Walkway Revival: Safety and Stability for a Stouffville Church

We implemented our proprietary concrete leveling process to deliver a lasting repair. First, small, strategic injection points were drilled into the affected slabs—careful preparation ensured precision and minimal disruption. Next, we injected our specialized high-density polymer beneath the concrete. This material expanded to lift the slabs back to their original, level height while filling voids and stabilizing the soil underneath to prevent future settling. Finally, we applied a premium crack and joint sealant to waterproof the walkway, protecting it from water damage and erosion.

The church walkway was fully restored—lifted, leveled, and stabilized—eliminating trip hazards and significantly improving accessibility for everyone. By choosing our solution, the church avoided the high cost and disruption of full replacement, instead receiving a durable, waterproofed repair that will protect their concrete investment for years to come.

Protecting Commercial Assets: Grimsby Concrete Leveling Solution

2025-12-03T11:51:43.05Z

The project utilized a polyurethane injection system (PolyLevel®) to lift and stabilize the affected slabs. Each slab was first assessed to determine the size of voids and the lifting requirements. Small-diameter holes were then drilled strategically to allow access for the high-density polymer, which was injected beneath the concrete. As the polymer expanded, it filled voids and applied controlled upward pressure, gradually raising the slabs to achieve precise level alignment. The method allowed for careful, uniform lifting of each panel without damaging the surrounding surfaces, and the polymer cured rapidly to provide structural support.

All sunken slabs were restored to a safe, level surface, eliminating trip hazards and restoring full pedestrian accessibility within hours of completion. The approach avoided the need for demolition, replacement concrete, and extended downtime, allowing the restaurant to continue normal operations. The high-density polymer provided long-term stabilization, significantly reducing the risk of future settlement and maintaining the professional appearance and safety of the facility.

From Unsafe to Stable: Quick Concrete Repair in an Active Facility

2025-12-02T16:14:52.05Z

Canadian Concrete Leveling implemented its advanced Polyurethane Injection (PolyLevel) system to restore the floor’s stability. This non-invasive process involves drilling small, dime-sized access points into the existing slab. Through these ports, a high-density, expanding polymer is injected directly into the voids beneath the concrete.

As the polymer expands, it fills the gaps and gently lifts the slabs to a stable, level position. The lightweight, rapid-curing material ensures immediate stabilization, providing a permanent solution in just a few hours. The process is clean, low-mess, and minimally disruptive, allowing facility operations to continue without interruption.

Results:

Immediate Stabilization: Floors were secured and stabilized within hours.
Durable Solution: The expanding polymer provides long-term structural support.
Clean and Non-Disruptive: Minimal drilling and no debris allowed normal operations to continue.
Cost-Effective: Faster and less labor-intensive than traditional concrete replacement methods.

By leveraging the PolyLevel system, Canadian Concrete Leveling delivered a safe, efficient, and permanent solution that restored the structural integrity of the facility’s floors while minimizing downtime and disruption.

Water? No Problem!

2022-11-22T00:00:00.05Z

Georgian Bay Islands National Park, ON

We are honoured and privileged to have been asked to help Parks Canada this past week with some infrastructure challenges on beautiful Beausoleil Island, Georgian Bay, ON - for the Georgian Bay Islands National Park. We helped park staff void fill and stabilize a slab-on-grade pump house floor, which over the years had voids develop under the concrete floor of the pump house. This structure housed several large water tanks that were used for water distribution throughout the park. The weight of the tanks when filled and in use was a concern for the staff, BUT that was only part of the challenge! Getting there required our crew to load our production truck into a local barging contractor's barge and get across Honey Harbour to the park. No challenge is too big for the CCL crew and staff! Thank you to Parks Canada for the call and all the help getting this project completed in one day with full use of the pump house and water system restored as soon as we were done.

The best from the rest: Why NexusPro® is the future of concrete sealing

2021-03-22T00:00:00.05Z

After dealing with sinking concrete and having it repaired, the last thing you want is to leave the job half-finished. While our PolyLevel® System is the best solution in the business for lifting concrete and filling voids, it doesn't deal with cracks or seams on the surface.

But we wouldn't leave you without any option for sealing your concrete, and that's where NexusPro® comes in.

Most people are familiar with sealant and what it's used for. They may have even done some of their own work around the house. The thing is, when you head to the hardware store looking for a concrete sealant, you'll end up leaving with a subpar product.

Most box store sealants, even those designed for concrete, become dry and brittle, cracking even more than the concrete slab it was supposed to protect.

Installation is another common issue since many homeowners don't always use a sealant properly. This may be okay around your shower or kitchen sink, but your DIY concrete repair won't hold up to the harsh outdoor elements like a trained installer's work would.

Fortunately, our Foremen are sealant experts and have been trained extensively using NexusPro®. Now, you're probably thinking:

"Well, all that sounds great, but what really makes it so different?"

NexusPro® is a construction-grade, silicone-based sealant formulated to provide long-lasting flexibility, durability and protection. Typically, harsh UV-light from the sun dries out traditional polyurethane sealants, but NexusPro® resists these rays, preventing cracking or bubbling. A single application can protect your driveway, patio, pool deck or steps for years to come, keeping soil washouts and compaction at bay.

"Okay, that all makes sense, but what else makes the difference?"

Aesthetic – Since NexusPro® resists UV-rays, it won't dry out and crack. This not only matches the smooth, finished look of your concrete slabs, but it keeps weeds and other debris from protruding out.

Fast Cure Time – 24 to 72 hours in the typical time it takes polyurethane sealants to cure, which is difficult to deal with in a high-traffic area. NexusPro® cures in only 60-minutes, giving you back your pool deck, driveway or patio in no time!

Durability – The absolute best features of NexusPro® are its long-lasting properties. It's completely flexible and waterproof and actually accommodates shrinking and expanding slabs as they move and shift over time.

Colours – NexusPro® is available in six different variants to match your current colour scheme (black, charcoal, gray, aluminum, limestone, desert sand) and for optimal blending customers have the choice to add sand or gravel to the sealant when it’s applied

Now that you know why NexusPro® is the future of concrete sealants give us a call for a free inspection and estimate! Trust your concrete with the "Pros" who use NexusPro®!

Dear front-line workers... thank you

2020-04-13T00:00:00.05Z

It’s time like these that show us what we’re made of.

The Novel Corona Virus has taken the world by storm in a way no one could have imagined. Companies have temporarily shut down, store shelves are sitting empty, and there’s an overall sense of uneasiness and uncertainty within the community.

We’ve all been watching the news every day trying to stay up to date. We’ve heard about all of the front-line workers risking their lives every day to keep serving the public. Their job has become that much harder, never knowing if the next call could be for a COVID-19 patient. It’s a hard enough job as it is, and COVID-19 is making it that much more difficult.

They’re facing new challenges each day, and like the rest of us, don’t always have answers to their questions. They keep their heads down, do their best to protect themselves, and continue to help our citizens.

But, as usual, you don’t hear any complaints. Front-line workers tirelessly continue to answer the call of duty day in and day out, without once hesitating.

That’s why we want to say thank you.

Thank you for going to work each day, even in the face of a pandemic. Thank you for your bravery and for never giving up on Canadians. For fighting fires, helping those in medical need, and keeping our communities safe. For keeping our roads and buildings safe, keeping us healthy and fed, delivering essential goods, or for manufacturing life-saving products.

I know these are only words on a page, but it’s one of the ways we can show our support and gratitude for our front-line workers. Keep reminding them that we’re here, we’re listening, and we care.

It’s our duty as Canadians to continue to support them as much as possible and do everything we can to make their jobs easier.

To all the front-line workers during this time:

Thank you!

Habitat for Humanity Teams up with Canadian Concrete Leveling to Fix a Hazardous Walkway in a Family Complex.

2018-01-15T13:04:19.05Z

Habitat Canada brings communities together to help families build strength, stability and independence through affordable homeownership.

Canadian Concrete Leveling donated their time and expertise and teamed up with Habitat for Humanity to lift a concrete slab that had sunk. The slab was collecting water and the cold weather was causing the water to freeze. It was becoming a serious trip hazard for the families living in the complex. Our team, Bill McKeown and Kyle McKeown, came in to lift the slab to ensure water would not continue to pool and freeze. Our PolyLevel Foam System was injected beneath the concrete by drilling dime sized holes through the concrete. The foam followed the path of least resistance underneath the concrete to fill all of the voids and then expanded. Our expanding foam is compressed and lifts the concrete to ensure the area is protected from further settlement.

The families can now be at ease knowing that there will no longer be a slipping and tripping hazard in the future.

Company Baseball Tournament

2017-09-26T00:00:00.05Z

We put together a team of employees who volunteered to play in a baseball tournament. Employees from Canadian Concrete Leveling, Clarke Basement Systems and Foundation Supportworks came together and played as a team. This was a great team building exercise because it allowed each of them to spend time with employees they normally wouldn't day-to-day. There were many shared laughs, so much support and it was an all around great experience for everyone involved. They got to know about each other and learned how to count on one another as a team. Doing events like this brings our company closer together and allows our employees to not only think of work but to think of fun as well. Working at Clarke Basement Systems is always a fun time. We are more like a family than co-workers. They all agreed they would do it again and look forward to more experiences like this in the future!
