DMI does carry out normal drilling work as part of specialist foundation
engineering, including anchors for construction pit linings or small-diameter
bored piles, but concentrates mainly on specialised drilling such as freezing
boreholes, sleeve pipe drilling, core drilling and drilling against pressing water.

 

Our drilling department is also able to offer all-round underpinning and slope
reinforcement services using shotcrete.

 

Owing to the specifically chosen equipment increments (3, 10 and 18 t), DMI
can execute all drilling processes and boreholes and above all also work under
extreme conditions. What’s more, our powerful hydraulic core drills, which are
small but perfectly suited to our drilling work, enable us to drill boreholes for
injection, ground freezing and exploratory purposes in rooms, shafts and
tunnels where it is not possible to deploy a crawler vehicle.
