Why Does Concrete Crack? The Reasons and Why It’s Important to Act Fast

When asking why concrete cracks, you’ll soon discover that there isn’t one distinct answer. There are a variety of factors that come into play, and in order to avoid the problem from occurring, you need to be sure that you’re taking the proper precautions and using the correct mixture.

Here are some common reasons why concrete cracks:

  • Too much water added to the concrete mix – While adding water may make the concrete easier to install, it greatly affects the strength of the finished material. By adding excess water, the concrete will shrink more, leading to cracks.
  • Poor quality concrete – Concrete is available in a variety of strengths, so you want to be sure you’re choosing an appropriate strength for your project. If you don’t select the correct strength, your finished material could be too weak and more susceptible to cracking.
  • Lack of expansion and control joints – Control joints are lines intentionally cut into a slab so that you can control where cracks will form. Expansion joints on the other hand are designed to accommodate concrete when it expands and contracts. It provides a space for concrete to move.

Over time, concrete naturally does have a tendency to crack, but said cracks can take different forms. By figuring out the type of crack you’re dealing with, you’ll be able to determine your next steps, and find the ideal solution.

Some common cracks that you may encounter include:

  • Shrinkage – This type of crack can occur either before or after hardening of concrete. Shrinkage which includes a loss of material leads to a lot of stress, causing cracks in the concrete.
  • Settling – These cracks typically occur when there is structural weakness of the underlying ground. For instance, you may see this if a large tree is removed nearby or when a utility trench has been refilled but not correctly compacted.
  • Expansion – When hot weather strikes, concrete expands and pushes against anything in its way. If there isn’t room for the concrete to expand, it causes expansion cracks.
  • Heaving – This is another crack type that comes about due to changes in temperature. These cracks develop when concrete is exposed to extremely cold weather. When it’s freezing outside, the freeze/thaw cycle may cause the concrete to lift and heave, which ultimately results in cracks.
  • Hairline – While hairline cracks aren’t considered that bad on their own, you’ll want to fix them immediately before they start to widen or get deeper, creating much bigger issues. You’ll typically find these on the surface level only.
  • Structural – These cracks need repairing immediately as they can compromise the structure of your material.
