As concrete is placed and being finished, chemical reactions begin to take place, causing the slab to increase in temperature. Stress, caused by shrinkage, begins to accumulate rapidly. At this time the concrete is looking for relief. If not relieved in a timely manner the concrete will relieve itself, resulting in random cracks appearing across the surface of the slab.

Without a control or relief joint made into the material, heat and cold aligned with curing can cause expanding and contracting of the concrete, creating uncontrolled cracks throughout. Those cracks will eventually ruptures and sections that can pull apart from the rest of the material.

Making a controlled cut in the concrete controls where the cracks appear. When this is done in determined spaced sections, the damage and cracking is kept at a minimum which prolongs the life of the concrete slap.

By placing True Early Entry joints at the appropriate spacing (usually 10' to 12' apart) the concrete finds the relief it is looking for and cracks directly beneath he cut.

The timing of True Early Entry joints are critical! Controlling random racking is all about the timing of the cut, not the depth of the cut. Cuts must be places between the initial set and the final set of the concrete. This control zone is the optimal time to give concrete relief when it is looking for it the most. Two hours after concrete finishing and before the final set is a general guideline.

The First Cut Skid Plate Guard System protects concrete spalling during the cut. A spring loaded skid plate holds it down and keeps aggregate from pulling out of the slab. The guard system is low maintenance and heavy-duty to withstand extended use on the job.
