Voids

Sometimes your concrete can appear to be in pristine condition, but you notice there is a large gap underneath it. This space between the slab and the dirt is called a void! And you definitely want to get it filled in. If you have voids beneath your slab, chances are if it hasn’t sunk and cracked already, eventually it will. Not to mention, sometimes those voids can be home to rodents or other creatures. Trust us, you’ll want to fill it in just in case.
