Cracks in a New Concrete Driveway: Normal or Worry?
Updated October 2026
Some cracking in a new concrete driveway is normal, because concrete shrinks as it hardens. Cracks that follow the saw-cut joints, or a fine web of surface cracks, are typical. A crack paired with a dip or sinking section points to a base or drainage problem. If you are not sure which kind you have, a free written assessment will tell you.
A crack in a driveway you just paid for feels like a failure. Most of the time it is not. Concrete moves a little as it hardens, and some cracking is part of how it behaves. The real question is what kind of crack you have.
Why new concrete cracks at all
Concrete shrinks as it hardens and dries. It is also much weaker when pulled apart than when pressed together. When the shrinking pulls harder than the concrete can resist, it cracks. Drying shrinkage is the most common cause. Extra water in the mix, a poorly prepared base and poor curing also add to it.
That is why installers cut control joints into a slab. A control joint is a planned weak line, usually cut to about one quarter of the slab’s thickness, so the concrete cracks in the cut instead of across the middle of the driveway. Timing matters: joints are normally cut within the first 6 to 18 hours, and not later than 24 hours. A joint cut too late can miss the crack.
Cracks that are usually normal
- Cracks along a joint line. The slab did what the joint was cut to make it do.
- Fine surface cracks in a web pattern. This is called map cracking. It usually comes from the surface drying too fast, and it is typically cosmetic.
Our warranty also draws this line: it excludes hairline cosmetic cracks, and it covers workmanship, including repairs needed because the work was done wrong.
Cracks that are worth a closer look
- A crack next to a dip. A sinking section often means the base has washed out or was never packed well. See our guide to why a driveway or slab sinks.

What to do now
- Take photos with a coin or ruler beside the crack, and note the date.
- Follow the crew’s guidance on curing. Moist curing is usually done for seven days, and longer is better, so ask when it is safe to drive on it.
When repair or replacement makes sense
Lifting works on a sound slab. A broken slab needs removal and a fresh pour. Whether you are weighing repair or replacement, the first step is the same: find out why it cracked.
Get it looked at
You do not have to guess. We will look at the crack, the slab and the drainage, and tell you plainly whether it is normal or needs work. The written quote is free, and we reply within one business day. Learn more about our concrete driveways, or about concrete repair and resurfacing.
Is it normal for a new concrete driveway to crack?
Yes, some cracking is normal. Concrete shrinks as it hardens and dries, and it is much weaker when pulled apart than when pressed. Control joints are cut into the slab to give that shrinkage a planned place to crack.
Which cracks in a new driveway should worry me?
Any crack paired with a dip or sinking section. A sinking section often means the base has washed out or was poorly compacted, which is a different problem from normal shrinkage.
Can a crack in a new driveway be fixed?
Often yes. A sound slab can sometimes be repaired, while a broken slab needs removal and a fresh pour. We look at the slab and tell you which one it is.
Does the warranty cover cracks?
Our lifetime warranty on labour covers workmanship, including repairs needed because the work was done wrong. It does not cover hairline cosmetic cracks. If you are unsure which your crack is, ask us for a free written assessment.
