Microtrenching is an installation method in which a narrow and relatively shallow trench is cut, typically on one side of an asphalt roadway. Trench dimensions range from .75′ – 2.25′ (19.1 mm – 57. 2mm) wide and 8′ – 16″ (20.3 cm – 40.6 cm) deep. While cutting, a vacuum system connected to the cutter wheel attachment cleanly diverts and transports the dry and dusty spoil away from the worksite. Once the conduit pipe is laid, the trench is back filled with a grout compound.
