Pilot Tubing also known as Guided Boring or “light” microtunneling, involves a three-step process: pilot bore, hole reaming and product pipe thrust. A very high accuracy is guaranteed by an optical guidance system that works in combination with a steerable drilling head, during the pilot bore stage.
This technology reveals its great effectiveness for the installation of gravity sewer pipes.
The minimum diameter of the starting shaft can be 2 meters (78 in).
