Concrete Lifting in Georgetown, Ontario: Restoring a Sunken Walkway

A homeowner in Georgetown, Ontario called Canadian Concrete Leveling after years of settlement left the front walkway and side path sitting below their original elevation. Using high-density polyurethane injection, our crew lifted the settled slabs back toward grade, smoothed out the uneven transitions and restored drainage away from the home — all while keeping the existing concrete in place.

The Challenge

Over time, the concrete walkways surrounding this Georgetown home had experienced significant settlement. Changes in the supporting soil, including erosion and the loss of sub-base support beneath portions of the slabs, caused sections of the front walkway and side path to drop out of their original elevation.

As the individual slabs settled at different rates, pronounced vertical transitions developed between adjacent sections. Cracking was also visible near the outer edges of the concrete. These changes created uneven walking surfaces and potential tripping hazards along the primary routes to the home's front entrance and side yard.

The settlement had also altered the original slope of the walkways. Areas that were intended to shed water away from the home were no longer maintaining the same grade, allowing rainwater and melting snow to collect closer to the foundation.

The objective was to restore the elevation and grade of the existing walkways, improve the supporting conditions beneath the settled sections, and address the uneven transitions without removing and replacing the concrete.

The Solution

Canadian Concrete Leveling completed a precision concrete lifting and leveling project in Georgetown, Ontario, using high-density polyurethane injection to restore the settled sections.

Strategically positioned, small-diameter access holes were drilled through the affected concrete slabs. High-density polyurethane material was then injected beneath the slabs into areas where support had been lost.

As the material expanded, it filled voids beneath the concrete and developed contact with the underside of the slabs. The crew monitored the response of the concrete during injection, allowing the settled sections to be raised in a controlled manner toward their intended elevation.

This controlled lifting process allowed the team to address the changes in elevation between the slabs while maintaining the existing concrete. The front walkway and side path were brought into a more consistent grade, improving the transitions between sections and helping restore the intended drainage direction.

Because the existing slabs were suitable for lifting and repair, complete removal and replacement was not required. Preserving the existing concrete also reduced the amount of demolition and material that would otherwise have been removed from the property and sent for disposal. It avoided the need to manufacture, transport and install an entirely new walkway system, making concrete lifting a more resource-conscious approach when existing concrete can be successfully restored.

The result was a targeted repair that addressed the settled areas while preserving the usable concrete already in place, with considerably less disruption than a full concrete replacement.

The Result

Following the lifting process, the major elevation differences between the settled slabs were reduced, resulting in a significantly more uniform walking surface along both the front entrance and side access path.

Restoring the grade also improved the way surface water moved across the walkways, helping direct precipitation away from the home rather than allowing it to collect against the foundation.

By addressing the loss of support beneath the settled areas and restoring the existing slabs, the project provided the homeowner with a functional repair without the demolition, disposal and construction disruption associated with complete concrete replacement.

The finished result preserved the usable concrete already on the property while improving the safety, grade and functionality of the exterior walkway system.

For this Georgetown homeowner, precision concrete lifting provided a practical way to restore settled concrete, improve the walkway's function and preserve the existing surface rather than starting over with a complete replacement.
