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.

  • Excavate & Base

    During the basing phase, it is also the time to develop a drainage plan that dos not leave you with puddles of water or a drainage plan allowing water to flow towards your house or garage.

    We will take the extra step on projects which have drainage issues to shoot elevations and work with the homeowner to make sure the best drainage possible is set before we install asphalt or concrete.
