Is Your Concrete Sinking or Uneven?

Sunken or uneven concrete is one of the most common problems homeowners face in the Twin Cities. Minnesota's freeze-thaw cycles, clay soil expansion, and natural settling all contribute to concrete slabs shifting out of place over time.

The result? Trip hazards on your sidewalk, water pooling on your driveway, gaps under your garage door, and an uneven patio that makes furniture wobble. Left unaddressed, these problems only get worse — and they can affect your home's curb appeal and resale value.

The Solution: Polyurethane Foam Leveling

At Inline Concrete, we use a process called polyurethane foam injection (also known as foam jacking or polyjacking) to lift your sunken concrete back to its original position. Here's how it works:

  1. We drill small holes — just 3/8" in diameter, smaller than a dime — through the sunken slab.
  2. High-density polyurethane foam is injected beneath the concrete through these holes. The foam expands rapidly, filling voids and lifting the slab.
  3. The concrete rises to level in minutes. We monitor the process carefully to achieve precise leveling.
  4. Holes are patched and cleaned up. Your concrete is fully usable within about 2 hours.

Why Foam Over Mudjacking?

Mudjacking has been around for decades, and while it works, polyurethane foam injection is a significant upgrade in almost every way:

Foam Leveling Mudjacking
Hole Size 3/8" (penny-sized) 1-2" (much larger)
Cure Time 15 minutes 24-48 hours
Waterproof Yes No
Weight ~2 lbs/cu ft ~100+ lbs/cu ft
Longevity Permanent (no known destruction point) May need redo in 3-5 years
Cost ~1/3 of replacement ~1/4 of replacement

While mudjacking may cost slightly less upfront, foam leveling's durability and waterproof properties make it the better long-term value — especially in Minnesota's harsh climate where freeze-thaw cycles can destroy mudjacking material within a few years.
