Garage floors take a lot of abuse

They are usually exposed to outside elements, including hot and cold temperatures and moisture. Vehicles also bring in salt and can leak gasoline or oil on the floor. The ground underneath can settle or rise up. All of this can result in cracks and spalling-which is broken up, flaked, or pitted concrete.

Crack-X can remedy this in two different ways, Repairing and Repouring.


  • Once we’ve inspected your floor, we can determine if it is fixable. If it is, our process includes:
  • Opening up the crack and removing the loose concrete and dirt and fully cleaning it out with compressed air.
  • Use a gravity-fed injection of a two-part epoxy resin.
  • We then mix the resin with coarse sand, which acts as an aggregate to help bond the concrete together.
  • This epoxy glues, or “welds”, the concrete back together and is actually stronger than the concrete itself.

Though this process doesn’t hide cracks, it prevents them from getting worse, and can be painted over.


Occasionally, cracks can be beyond repair. In these situations, a partial or full garage floor re-pour is the answer.

Sometimes the floor issues are limited to just a certain area, such as near the garage door. In this case, it would be unnecessary to repour the whole floor.

The Crack-X process for a re-pour is:

  • Saw, cut, jackhammer and remove the problemed concrete.
  • Prepare the surface underneath.
  • Repour new concrete back to the existing level. We typically use a mix of concrete rated at 4000 psi, which is stronger than the 2500psi more commonly used. It includes a fiber mesh for strength, to help prevent future cracking.

Of course, at times the whole floor needs to be re-poured, in which case we would follow the same process outlined above at a much larger scale.
