Microtunnelling is a full-face method where pipes are remotely pushed forward below groundwater level. SONNTAG has experience throughout Europe and cooperates on-site with partner companies from the respective country. As a pioneer of microtunnelling in Germany, we are capable of carrying out even the most complicated sewer construction measures on time and accurately.
We work with state-of-the-art micro machines that allow for the replacement of worn drill bits underground. This can reduce the number of intermediate shafts, significantly lowering construction costs. From cohesive soils to sand and solid rock, drives can be executed in various soil types. We are also equipped for microtunnelling with air-supported face.
