Concrete must be cut to control unnecessary cracking. As concrete dries moisture is released causing the molecular structure of the concrete to shrink. The saw cut creates a weakness point which relieves the stresses built up due to shrinkage. The 10mm rebar will allow very little movement as the concrete cures and settles, it also contributes to future strength and stability.
Saw cuts allow for movement that may occur beneath the concrete due to temperature changes and climate conditions.
Benefits of Cutting Concrete
Cutting concrete allows it to expand and contract due to temperature change, move up and down due to frost action, and be poured in large panels thus eliminating point load settlement. It also increases surface runoff.
Example: Below you will see a comparison between concrete and pavers/interlocking brick.
As water penetrates the subgrade of your concrete unit pavers, it can become saturated and soft. Winter brings temperatures that freeze moist ground and cause heaving. As a result gaps in bricks get larger allowing more water into the subgrade, restarting the cycle.
