Microtrenching

Diamond microtrenching is a method of using diamond blades to place ducts in roads and sidewalks.
By using diamond blades the impact becomes minimal on the existing asphalt while the by-product is a fine powder.

  • Advancement of 500 meters per day, due to a highly automated process.
  • Constant sawing depth
  • Less cost when it comes to project management
  • Less disturbance when it comes to traffic and emergency vehicles
