TUNNELLING
Denys is a past master of boring tunnels in soils with varying geology, under rivers or global cities using unique tunnelling machines. Our highly driven drilling specialists work in many European and North African soils. With great success! Through our in-depth knowledge of micro- and mid-size tunnelling (just about the most difficult underground discipline) Denys is also the right partner for larger diameters.
