Filling Dangerous Voids Under Slabs

Filling Dangerous Voids Under SlabsWhy Voids Under Your Slabs are Dangerous

If you own or manage a property with concrete slabs, you need to understand the danger posed by voids in the supporting soil. Large gaps in the soil beneath your slabs are a red-alert problem for a couple of key reasons:

  • Any equipment or vehicles on your slab are at risk. We have linked to this video before, but it is very relevant here: click to view cars falling through a collapsing floor. You definitely do not want this happening in your warehouse, parking area, showroom or garage.
  • People are more valuable than any vehicle or piece of equipment could ever be. Don't put your employees, tenants, customers, friends or family at risk.

Signs You Might Have a Void Under Your Slab

There are a few key indicators you should look for when trying to determine the stability of soil underneath your garage:

  • Are there cracks in your slab?
  • When you gently tap on your slab with a hammer, does it sound "hollow"?
  • Is your slab sinking?

Filling the Void and Repairing the Slab

The good news is that filling voids with high-strength polyurethane is generally an efficient fix when you're dealing with a qualified contractor. And you can use the slab in as little as 45 minutes after the repair job is done.
