In Sarnia we offer concrete raising and levelling. Settling soil near the lake means a fair number of driveways, patios and pool decks settle unevenly over time. We inject expanding foam beneath the existing concrete to lift it back into place without a full replacement.
Why Slabs Sink Around Sarnia
Concrete doesn’t fail because the concrete is weak. It fails because the ground under it moves. Water erodes soil out from beneath the slab, poor drainage accelerates it, freeze-thaw works it loose, and eventually a void opens up and the slab drops into it.
Polyurethane foam addresses the actual cause: it fills that void and restores support beneath the concrete. It’s impervious to moisture under the slab, resistant to freeze-thaw, and light enough that it doesn’t become the next problem.

Slabs We've Levelled in Sarnia
Working in Sarnia
Water erosion and soil settlement are the most common reasons concrete sinks, and both are frequent around Sarnia properties. Polyurethane foam fills the void that caused the settling in the first place: it’s lightweight, impervious to moisture beneath the slab, and resistant to freeze-thaw.
Moisture Resistant
Foam is impervious to water and moisture beneath the slab.
Freeze-Thaw Rated
Holds up through Ontario’s freeze-thaw cycles.
5-Year Warranty
All polyurethane levelling work is backed by a 5-year warranty.
What We Level in Sarnia
Driveways
Settled and uneven driveway slabs lifted and re-supported from below.
Sidewalks & Walkways
Joints that have dropped into trip hazards, brought back level.
Patios & Pool Surrounds
Re-sloped so water sheds away from the house and pool edge.
Steps & Landings
Sunken entry steps and landings raised back to their original height.
Sarnia Questions, Answered
What causes concrete to settle in the first place?
Water erosion, poor drainage, freeze-thaw cycles, soil settlement, tree roots, poor original compaction and voids opening beneath the slab.
Does the foam hold up to moisture?
Yes. It’s impervious to water and moisture beneath the slab, and resistant to freeze-thaw cycling.
How big are the holes?
5/8 of an inch. They’re patched before we leave and are far less noticeable than traditional mudjacking holes.
Do you pour new concrete in Sarnia?
Not currently. Sarnia is covered by our raising and levelling service.
