The HEM Magna Cut pavement saw is a unique solution to the challenge of sawing longitudinal expansion joints into continuous concrete slabs before they crack. To avoid marring the green concrete, only the blade touches the surface. Crawler tracks straddle slabs as wide as 50 feet, and the saw suspended from a beam moves across it at the operator’s control. The unit can handle crowned slabs and curbs, skewed joints and full-depth cuts.
