Microtunnelling ND 250 - ND 2400
Microtunnelling is a full section system. You can drive pipe remote-controlled.
SONNTAG has its practical experiences from projects in Europe and the cooperation
with partners in the particular country. As pioneers of microtunnelling in Germany
we are in the position to realise difficult sewer projects punctually and exactly.
We work with the state-of-the-art microtunnelling machines so it is possible to
replace worn out boring cutters underground. Thereby we can reduce the number of
pits and so the construction costs can be much reduced. From compacted soil beyond
sand until consolidated rock we pass different kinds of ground. We are equipped
for microtunnelling and compressed air supported working face.
