Curb Grinding eliminates saw cuts in the gutter which allows water to create a void under the street. Grinding texturizes the curb so the surface is not slippery. Adjusting the angle of the slope is a quick and easy task by moving a lever from a minus 14 degree slope, 0 degrees, to plus 14 degrees and anywhere in between. A horizontal saw position on the machine eliminates a chipped edge on the dirt side of the curb which assists in an even transition and a straight and consistent edge to make the concrete approach expand and retract evenly.
Previous to curb grinding, cutting the curb along the gutter and using a piece of machinery to break the curb off was the standard operation. There is a major problem with this method. Making a saw cut in the flowline, allows water to creep under the street and under newly poured approach. When water is trapped under the street and the temperature drops below freezing, the water will freeze and heave the approach and the street separating the two, which increased the gap of the saw cut. Most Cities are requiring curb grinding, horizontal cutting or if cutting the street is necessary, the full depth cut must be 24 - 36" away from the flowline.
Having a steep rolled curb with an abrupt bump will ruin tires and shocks, mess up the vehicle's alignment, and scrape up vehicle ground effects. We can grind the curb and about 10 - 12 inches of the approach to eliminate that harsh bump.
ADA requires handicap accessible curb ramps. Grinding curbs to attain this requirement is accepted as an alternate solutions to cutting, removing and repouring the curb.
