Safety Marking, Inc. has developed specialized equipment designed to meet the ever growing demand for recessed pavement markings. With our state of the art grooving equipment, we can recess a line 50-120 mils below the surface of the road. The cut is smooth with vertical edges providing the optimal surface on which to place the markings.The grooving process protects the markings from snow plow damage as well as normal traffic wear and tear thus improving the reflectivity and extending the life of the line.
