Voids and cavities under any concrete area can lead to major issues. From shifting, sinking, cracking, or worse – broken concrete pieces. If you’re experiencing any of these issues, it’s possible there are one or more voids under your slab. In that case, it’s time to call the professionals, Mr. Level – Cleveland, OH’s concrete experts.

How Do I Know If I have a Void?

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.
  • Hollow Sounds: underneath the slab when walking overplaying basketball on

Do I Really Have To Fix The Voids 
 Under My Concrete?

Mr Level Concrete Void Repair

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.

How We Handle Concrete Void Repair

Mr. Level uses polyurethane to quickly and efficiently fill voids and stabilize concrete. We’ll start by drilling small holes in strategic areas around the concrete. Then, we pump polyurethane foam under the slab to fill the empty cavity. This allows makes the entire concrete area more stable and prevents it from settling. This method is quick and requires very little downtime. The treated area will be ready for normal traffic within just a few hours.
