Micro Trenching
Micro Trenching is the process of deploying fiber optic or other communications cable in a narrow, shallow saw cut in roadways or sidewalks. Micro trenching is an alternative construction method to Open Cut Trenching and Directional Drilling.

Micro trenching is performed using a standard concrete saw or specialized saws designed specifically for micro trenching by manufacturers including Marais, Ditch Witch and Vermeer.



A narrow saw cut ranging from 13 mm (0.5 inch) wide to to 38 mm (1.5 inch) wide is cut to a depth of 150 mm (6 inches) 400 mm (15 3/4 inches) deep is made in a roadway or sidewalk and the cable is either direct buried or placed in a protective conduit.

Micro trenching reduces the amount of excavation required in comparison to an open cut trench which results in faster deployment and reduces the amount of materials required to restore the excavation thereby reducing costs. The cost benefits of micro trenching are realized primarily in deployments where trenches must be made in asphalt or concrete roadways and sidewalks.

Micro trenching also reduces the impact on the community during the construction process
