How to Fix a Sinking Concrete Slab With Polyurethane Foam

If your concrete slab is sinking, you need a fast and solid solution. Polyurethane foam can lift your slab without the mess of older methods.

Why Slabs Sink

Your slab sinks because the ground under it moves. Rainwater, melting snow, or poor soil compaction creates empty spaces below the concrete.

When nothing is holding it up, it drops. If left alone, this can make the problem worse, especially after a tough winter or heavy rains.

In Winnipeg, freeze and thaw cycles add stress. Cracks form, and slabs shift.

Why Choose Polyurethane Foam Concrete Repair

- The foam is light but strong. It won’t add weight and cause more sinking.- It fills gaps fast and lifts the slab in minutes.- You can use your driveway or patio the same day.- It works well for both small and large areas.

This is one of the leading concrete levelling solutions in Winnipeg.

How Foam Injection Works

1. Small holes are drilled in the slab

2. Foam is injected into the holes

3. The foam expands, lifts the slab, and fills the empty spaces below

4. The holes are patched, and the area is ready for use.

Example: A customer in Winnipeg used foam to lift a sidewalk that had sunk 3 inches. The job took less than 3 hours.

Why It Works in Manitoba

Foam holds up well in all seasons. It doesn’t crack or shrink like other materials.

That makes it perfect for Winnipeg concrete repairs.

Foam is also resistant to water. In Winnipeg, where snow and rain can be heavy, this helps stop future damage. The material won’t wash away or lose strength over time.

Another reason foam works well is that it cures quickly, even in cooler temperatures. This means fall and spring are great times for this type of work.
