Diamond Grinding

Diamond Grinding concrete and asphalt pavements. Including full lane and bump grinding to meet DOT/FAA regulations.

Diamond grinding is a concrete pavement restoration (CPR) technique that provides a smooth riding surface with the desirable friction characteristics on concrete pavements that have developed excessive roughness. Diamond grinding offers numerous advantages over other rehabilitation alternatives, including the following:

  • Costs substantially less than an overlay.

  • Enhances surface friction and safety of an old pavement surface.

  • Can be accomplished during off-peak hours with short lane closures and without encroaching into the adjacent lanes.

  • Grinding of one lane does not require grinding of the adjacent lane, which may have perfectly acceptable surface characteristics.

For concrete pavements in good structural condition, diamond grinding can be a highly effective and economical rehabilitation alternative. The history of continuous diamond grinding for pavement restoration dates back to 1965, to a 19-year-old section of the San Bernardino Freeway (I-10) in California that was diamond-ground to eliminate excessive faulting. Since then, diamond grinding has become a major element of CPR projects.
