LaserPro diamond saw blades for joint widening concrete (16 - 72hp). Joint Widening blades are used to widen, control joints in concrete or in sealed joints in old concrete. These blades are also ideal for grooving concrete and asphalt roads and airport  runways.  Also the insulation of traffic loop sensors. 

These blades are fitted with sandwich segments. A sandwich segment contains a high concentration of diamonds on the outside layers of the segment.  This maintains the segment's shape and width significantly increasing the life of the blade.
