Garage Floor Sinking? Here’s How Foam Lifting Can Help

Request A Free Estimate

Foam lifting is a fast, affordable, and long-lasting solution for sinking garage floors. It works by injecting high-density polyurethane foam beneath your slab to raise it back into position—without tearing anything out. Most repairs are done in a day and last over 10–20 years.

Is Your Garage Floor Sinking, Cracking, or Sloping?

You’re not imagining it. If your garage floor is uneven, cracked, or starting to slope, it’s likely sinking due to shifting soil, water erosion, or poor initial construction.


You might notice:

√ Cracks where the floor meets the walls

√ Doors that don’t close evenly

√ Pooled water or oil that runs to one side

√ Uneven tire wear on parked vehicles


It’s more than an eyesore—it’s a safety hazard, and it can affect your home’s value.

Why Foam Lifting Is the Smarter Solution

Unlike traditional repair methods that involve breaking up and repouring the slab (which can take days and cost thousands more), polyurethane foam lifting is:

Benefit Foam Lifting Full Replacement
Cost Lower Much higher
Time to Complete 1 day 3–5 days (plus drying time)
Mess Minimal Dust, demo, debris
Downtime Back to use same day 5–7 days minimum
Weather Resistant Yes (waterproof foam) Varies depending on mix

Foam lifting isn’t a patch—it’s a structural fix. It stabilizes the soil beneath your garage and lifts the slab precisely into place.

How It Works

  1. Small holes are drilled in the sunken areas of your garage floor.
  2. Polyurethane foam is injected underneath, expanding to fill voids and raise the slab.
  3. Our team monitors and adjusts the lift in real time.
  4. Holes are patched and sealed—your floor is ready the same day.
