How to fix minor cracks in your home’s foundation

Since concrete shrinks and settles as it cures, it’s common for hairline cracks to appear on basement walls. You don’t have to worry about these minor cracks. Simply monitor them to make sure they don’t get any bigger.

However, it’s best to promptly seal any cracks that are wider than an eighth of an inch. To do so, you’ll need to purchase a caulking product formulated for concrete.

Once you have the materials you require, scrub the crack clean with a wire brush. Then, inject the caulking product along the entire length of the crack. This will help keep water out and prevent the crack from worsening.

However, if you have foundation cracks that are wider than half an inch, it’s best to call a contractor who can assess and repair the damage. Only a professional will be able to tell you if there are serious structural issues with your foundation that need to be addressed.
