Making relief cuts in concrete is an overlooked technique that extends the life of concrete by controlling random cracking. Making these relief cuts is done using an early-entry blade and soff-cut saw during the concrete's finishing process called the "green zone". Adhere to the following list of best practices will ensure your relief cuts are made confidently!

Best Practices for Quality Soff-Cut® Joints

1) Timing of cut! Make sure you cut in the Green Zone. (1 to 2 hours after finishing and before the final set. Use hand, foot & roll test.)

2) Make sure the blade break-in time is honored. Operate the soff-cut saw at half of the normal forward speed for approx. 100 lineal feet to allow the blade to open up, remain cool, cut faster, and promote full blade life.

3) Make sure the blade is aligned in the skid slot and not cutting into the skid causing damage!

4) Find the optimum forward travel speed. (Pulling left, too slow. Pulling right, too fast.) The blade must cut as freely as possible, not putting too much pressure on either side of the joint.

5) Don’t walk on saw joints while cutting!

6) Transport and store saw without blade but always with a skid plate attached!

7) Change the skid plate with every new blade! (If starting out the day with a used blade and skid, inspect the bottom surface of the skid to make sure there is no damage.)

8) Inspect the used blade to make sure none of the diamond segments are overheated and glazing over!

9) Check blade block plungers making sure they are moving up and down freely allowing proper pressure of skid on the concrete surface! (Clean blade block daily.)

10) Use joint protectors at saw joint intersections and at saw drive wheel locations!

11) Don’t sweep across the soff-cut joints only in the same direction as the joints!
