The Types of Cracks and What You Can Do About Them

Concrete cracks come in many different varieties and, in order to protect your commercial property, it helps to know about them.

Let’s take a look at some of the most basic kinds and explain how they can be fixed so that your property is always in its best shape.

  • Surface Cracks – These are the kinds of cracks that are more eyesores than anything. While they don’t pose a danger to the property, they do take away from it’s appearance and can be a distraction. In order to fix these kinds of issues, you would need to install a thin overlay, which would cover the existing cracks and restore the surface’s appearance. The problem can also be corrected by filling the crack with a sealant, which adhere to the concrete and help make the cracks vanish from sight.
  • Structural Cracks – This is the kind of issue any commercial property manager truly needs to worry about. If concrete cracks are extensive enough that they threaten the integrity of the building, then the problem needs to be taken care of as soon as possible. For this kind of job, you would typically see an epoxy injection to fill in any concrete cracks. This helps restore the material’s strength and is done by cleaning the crack of any dirt and then sealing surface cracks with gel. Epoxy is then injected into deeper cracks via venting ports to help restore the surfaces strength. When wondering how to repair concrete cracks that can cause structural issues, it’s important to know that this method only applies up to a certain point. If the concrete surface is too far gone, then it may have to be removed and replaced entirely.
  • Sunken Concrete – While concrete isn’t cracked in this instance, it can still be a serious issue if it’s sunken. In order to fix it, the concrete needs to be lifted using a method called hydraulic jacking. This will raise the slab by pumping grout or a beam beneath it to raises its elevation back to where it needs to be. These are the basics of concrete repair for the most common situations that commercial property owners often have to deal with, but there could easily be others.
