Why does concrete crack?

Why does concrete crack?

Concrete is not a flexible material and is affected by the freeze and thaw cycles we expirence in Minnesota.


Freeze and thaw cycles cause movement in the ground which can cause the concrete to crack. The best way to minimize cracking is to use a good base, strong concrete, and install rebar and control joints for reinforcement.

Be sure to choose a concrete contractor that is experienced in proper driveway basing and reinforcement, and that knows how to properly cure a driveway during the drying process, as cement that dries too quickly is also prone to cracking.
