Uneven concrete isn’t something you can afford to ignore. Cracks and uneven surfaces not only create tripping hazards but also point to underlying problems that can get worse over time. At Olson Foundation, we understand how frustrating it can be to deal with these issues, which is why we specialize in leveling uneven concrete with proven techniques that restore stability and help protect your investment.

What Causes Uneven Concrete?

Before exploring the best ways to fix an uneven concrete floor, it’s important to understand what causes the problem in the first place. Several factors contribute to uneven surfaces:

  1. Soil Settlement: Over time, soil beneath the concrete can shift, causing certain areas to sink while others remain in place.
  2. Expansive Clay Soil: In regions like Kansas City, expansive clay soil absorbs water and swells, then contracts when dry, leading to movement in concrete slabs.
  3. Poor Initial Installation: If the subgrade beneath the slab wasn’t properly compacted, the concrete may settle unevenly over time.
  4. Moisture Issues: Too much or too little moisture in the soil beneath a concrete slab can result in movement and shifting.
  5. Tree Roots: Growing tree roots can push against the underside of a concrete slab, creating uneven sections.

Effective Methods for Leveling Uneven Concrete

There are several ways to fix an uneven concrete floor. The best approach depends on the cause and severity of the problem.

1. Polyurethane Foam Injection (Polyjacking)

One of the most effective ways to level an uneven concrete slab is through polyurethane foam injection. This process involves:

  • Drilling Small Holes: Small holes are strategically drilled into the affected concrete slab.
  • Injecting Expansion Foam: A specialized polyurethane foam is injected beneath the slab. As the foam expands, it fills voids and gently lifts the concrete back into place.
  • Sealing the Holes: Once the concrete is level, the drilled holes are sealed, leaving a nearly invisible repair.

This method is highly effective, minimally invasive, and long-lasting.

2. Slab Pier Installation

For more severe settlement issues, slab piers may be required. The process involves:

  • Drilling Circular Holes: Holes are drilled into specific points of the damaged slab.
  • Installing Helical Piers: Helical piers (which function like large screws) are driven deep into the ground until they reach stable soil beneath the shifting slab.
  • Lifting the Concrete: The piers are adjusted to lift and stabilize the slab.
  • Filling the Voids: Once the slab is repositioned, any remaining empty spaces beneath it are filled using polyurethane foam or another stabilizing material.

Slab piers provide long-term stability, especially for older homes where soil movement is a recurring issue.

Can Uneven Concrete Be Prevented?

While no solution can completely prevent concrete movement: especially in areas with expansive clay soil: there are steps homeowners can take to minimize the risk:

  • Maintain Moisture Levels: Watering your yard a couple of times per week during dry seasons can help prevent the soil from shrinking and shifting beneath the slab.
  • Ensure Proper Drainage: Keep gutters and downspouts clear to prevent water from pooling around the foundation.
  • Monitor Tree Growth: Be mindful of tree roots that could lift or shift the concrete over time.
