Will concrete crack?

​Q: Will the concrete crack?
A: Concrete requires control joints to allow for shrinkage when the concrete is curing.  The control joints we install in all our concrete work are completed in specific locations and design to greatly reduce uncontrolled cracking.  All of our concrete projects have a very low chance of uncontrolled cracking.  Uncontrolled (cracking) joint is when the contractor has not installed the control joints in the correct location and before 30 hours of placement.  If the concrete hasn't been cut with expert precision ,  than yes the concrete will crack randomly and uncontrolled.   Controlled (cracks) joints basically means that the contractor controls the time and location of where the concrete cracks.  The control joints are designed prior to concrete placement or during.  Successful controlled cracks are done with expert precision, within 30 hours of placement and other skilled tricks that aren't mentioned here.  The controlled joint will be a straight line cut into the surface of the concrete approximately 1/3 of the thickness of the concrete.  This is more structurally sound and visually appealing.
