Garage Threshold and Walkway Leveling in Ancaster, Ontario
Challenge
At this Ancaster, Ontario home, the homeowner was dealing with multiple areas of concrete settlement that had become both a functional frustration and a safety concern. The primary issue was at the garage entrance, where the driveway had sunk significantly, creating a pronounced vertical lip between the driveway and garage floor. This resulted in a jarring impact every time a vehicle entered the garage and introduced a clear trip hazard in a high-use area.
In addition, the side walkway had also experienced settlement, causing it to slope toward the home rather than away from it. This uneven surface not only made the walkway difficult and unsafe to navigate, but also created improper drainage conditions. Instead of directing water away from the structure, the slope increased the risk of water collecting near the foundation—an issue that can contribute to long-term moisture concerns and soil instability if left unaddressed.
Solution
To correct both issues efficiently and without the disruption of full concrete replacement, our team implemented a precision polyurethane injection concrete leveling system. Small, strategically placed access points were drilled through the affected areas, allowing us to inject a high-density, expanding polyurethane material beneath the slabs. As the material expanded, it filled voids caused by soil settlement and provided controlled lifting force to raise the concrete back toward its original position.
The driveway slab was carefully lifted to restore a smooth, flush transition at the garage threshold, eliminating the harsh elevation change and improving vehicle access. We then addressed the side walkway, using the same injection process to level the surface and re-establish proper pitch for effective drainage away from the home.
The result was an immediate and noticeable improvement. Both the driveway and walkway were restored to safe, level, and functional surfaces, with enhanced drainage performance and long-term stability. Because the polyurethane material cures quickly, the homeowner was able to resume full use of both areas the same day, without the mess, noise, or downtime associated with traditional concrete replacement.
