Concrete Slab Stabilization

How to Detect Voids Under Concrete

Many people don’t know if there is a void under their driveway, patio, or other concrete slab until after the concrete has settled. Often, if your concrete slab has a void underneath, you’ll hear a “thud” from the concrete shifting when you park on your driveway or even by dribbling a basketball on it. Here are some additional signs of a concrete void:

  • Concrete cracks: Look for physical damage from small cracks to pieces breaking off.
  • Deterioration: Beyond normal wear-and-tear, check if the concrete is chipping or eroding.
  • Breaking corners: Breaks in the corners of concrete are a sure sign of unsupported, hollow ground.

Effects of Voids in Concrete

With any home or commercial project, it’s always easier to catch an issue before it turns into a bigger and more expensive problem. The same is true for stabilizing your concrete. If you have a void under your concrete and don’t repair it, it can lead to cracks and settling. In addition, there are many long-term effects of voids in concrete, including land erosion, water retention, and trip-and-fall hazards.

Concrete Stabilizing Solution

Mr. Level uses polyurethane to quickly and efficiently fill voids and stabilize concrete. We’ll start by drilling a small, dime-sized hole into the concrete. The polyurethane foam is then pumped under the slab to fill the void and allow the concrete to become stable and safe from settling. Because of the quick cure time and minimal invasiveness, we can stabilize your concrete in just a couple hours without leaving a mess behind.

Don’t wait to fill the void under your concrete! Concrete stabilization is a much more cost-effective solution than concrete leveling or replacement. If you think there might be a void under your concrete slab, contact Mr. Level today to request a free quote.
