Should You Fix the Cracks in Your Concrete?Posted Thursday, September 18, 2014
It depends. Experts will tell you that concrete will always crack; it’s just a result of expansion and contraction caused by moisture and temperature changes. If you’re worried about cracks in the concrete at your home, consider these three things:
Location. Cracks in the sidewalk or patio are of less concern than cracks in the foundation of your home. But if a crack in the walk has caused a vertical gap of ¼ inch or more, it creates a trip hazard and should be addressed.
Size. Hairline cracks are nothing to worry about. If you try to patch them, they become more noticeable, not less. Wider cracks can be repaired with filler. Cracks over ½ inch wide should be filled with foam backer rod before being patched. Consult with a professional to find the best materials for your situation.
Activity. An active crack could be cause for concern. Are you worried that the crack is widening, but not sure? Try putting a piece of masking tape across the crack. If the tape tears, the crack is widening. When that happens, you want a professional to find out what is going on.
If you have cracks in your basement walls, you can have them injected with polyurethane to prevent water leakage. For large projects, it’s best to hire a professional.
