Cut Concrete Pavement: When to Cut and How To Cut
2020-8-26 · Wet concrete is very hard to cut and can dismantle very easily on the application of force. When the concrete is cut too early, ravelling occurs, which causes the aggregates to dislocate from their position. This leads to weakened edges along the cut. This can also cause permanent damage to the diamond saw cut machine.
