Microtunnelling is a widely used trenchless technique to install pipelines underneath the ground. It brings new opportunities for expansion of underground infrastructure in urban areas where conventional methods are uneconomic or impossible.
This technology is very accurate and can be used in all ground conditions.
Microtunnelling O 1000mm ÷ O 4000mm with the use of “open cutterhead” MH-2 and MH-3 Machines
Microtunnelling O 250mm ÷ O 4200mm with the use of “closed cutterhead” AVN Machines
