As concrete hydrates and begins to set, it develops internal stresses. The objective in controlling shrinkage cracking is to relieve these stresses before they seek their own relief in the form of random cracks. * Husqavarna
Using this system eliminates random cracking. Stress is relieved every time below the cut, exactly where the contractor wants it to. Cutting in the green zone allows a shallower cut, which achieves a greater aggregate interlock for a stronger slab, and minimises the amount of joint filler that might be needed.
