CONCRETE Expansion CUTTING IN BALLARAT AND MELBOURNE
Concrete Expansion Cutting
Expansion or Control joints are shallow, specifically positioned cuts in concrete structures, at regular intervals, to allow cracking to occur in a controlled environment.
Control joints are planned cracks which allow for movements caused by temperature changes and drying shrinkage. In other words, if the concrete does crack, you want to have an active role in deciding where it will crack and that it will crack in a straight line instead of randomly.
