Concrete Diamond Grinding

Concrete diamond grinding removes roadway imperfections caused by construction and/or heavy usage. The immediate result is an improvement in pavement smoothness, surface texture, skid resistance, safety, and noise reduction.


  • Runway GroovesImproved costs over other rehabilitation techniques
  • Work is usually conducted during off-peak hours, which shortens lane closure times and minimizes encroachment into adjacent lanes.
  • Fewer lane closures (diamond grinding in one lane does not require grinding of the adjacent lane which may have acceptable surface characteristics)
  • Eliminates the need for taper (a requirement with overlay alternatives at highway entrances, exits, and side streets)
  • Does not affect overhead clearances underneath bridges or hydraulic capacities of curbs and gutters on municipal streets.
