How and Why Do Foundation Cracks Form?

Concrete cracking is common and will affect both indoor and outdoor concrete. Take a walk down a sidewalk or check out the foundation in a basement and you may come across cracks. When properly handled, cracking often isn't a big deal. That said, “properly handled” is the keyword, and if you notice cracks, it's smart to contact a concrete service.

Concrete may crack as the foundation moves or settles. Over time, the very ground itself will shift, and this could cause pressure and strain on the concrete itself.

With outdoor concrete, such as in a driveway, it's common for the concrete company to put in so-called “control joints.” Essentially, the concrete is designed to crack at certain places. This allows you to control the “where” of concrete cracking.

Indoors, control joints often aren't used with foundations. This may lead to uncontrolled cracking. While some concrete cracking in a foundation is normal and to be expected, if the concrete starts to rise and fall, becoming very uneven, that could be a serious problem.

Ultimately, concrete is a great building material. It's durable and resistant to weather, among other things. However, concrete cracking in a foundation can be a problem. Fortunately, a concrete services contractor can provide crucial assistance both in and outside of your home.
