What happens if you don't cut concrete?
Cutting too early can mark the pavement surface as well as cause joint raveling. Late sawing can result in random concrete cracks. Shallow cracks aren't sufficient to prevent uncontrolled cracking while deep cuts are excessively labor intensive and undermine the aggregate interlock in the concrete.
Why do you cut lines in concrete?
Concrete lines are also called control joints or cuts. When contractors pour concrete, they include these lines in specific places to control and prevent cracks. As the concrete dries, shrinks, moves and bears weight, it can crack.
Why do they cut lines in concrete driveway?

What is scoring concrete?
An excellent option for both new and old slabs, scoring is an easy way to add depth and texture to an otherwise blank slate.
