You’re backing out of your garage one day to start your morning commute when you notice it—long, winding, jagged: a crack in your concrete garage floor. Should you panic? Is this crack just the result of age? Is it simply cosmetic? Or is it severe enough to be indicative of larger problems?


Concrete naturally cracks for countless reasons. Generally speaking, most cracks are simply superficial and pose no threat to your concrete structure’s integrity. In other words, you’re probably not in trouble! However, severe cracks can suggest deeper issues that will require remedial concrete work. Below, Creative Concrete, creator of everything from concrete driveways to concrete patios, discusses how to know when cracks cross the line from a simple aesthetic change to a real concern.

Why does Concrete Crack?

As stated above, many concrete cracks are completely normal and are no reason to fret. Due to concrete’s composition, it can naturally crack a little as it dries, for one, and under natural external stressors, cracking over time is to be expected. However, if the cracks are wide enough, that’s definitely a sign that you need professional help. A nice rule of thumb: if you can drop a nickel in the crack, then it’s a cause for concern, and you should call a local concrete company to begin remedial work. Otherwise, your crack is probably nothing to worry about.


Aside from time and stress, here are a few of the many reasons that will cause concrete to crack:

●        Heaving. As the ground underneath the concrete freezes and thaws, it expands and contracts, putting stress on the concrete. If the concrete does not take this stress evenly (that is, if it cannot rise and fall levelly), it will crack.

●        Expansion. As concrete heats up, it expands in volume. When concrete expands and pushes against something that will not give, the strain can cause a crack.

●        Soil settling. If the soil beneath the concrete becomes soft or saturated, the sheer heaviness of the concrete can cause that soil to compress—in other words, to settle. If this process occurs unevenly, cracking can result.


As you can see, many things can cause your concrete to crack, but generally speaking, these cracks are normal. If you’re concerned about your concrete’s structural integrity, though, a concrete company can give you advice regarding the best way to proceed.
