Microtrenching uses a machine the size of small car to cut a slot in the road surface ensuring that installing Fibre no longer involves days of trenching, burying pipes, and then backfilling and reinstating the pavement back to its original state. Depending on the type of road and the depth of existing services – like electrical power and water – this ‘micro trench’ can be 20mm to 60mm wide and 300mm to 500mm deep, usually near the edge of the roadway. The machine has a blade in front (much like a giant angle grinder) that cuts into the road surface.
Depending on the terrain and the experience of the team, a four-man team and a machine can conceivably complete between 200m and 400m of trench per day.
Note that only select suburbs allow microtrenching.
