New machine BM 400LCS
The new developed auger drill BM 400LSC combines the advantages of the well proven compact machines with the flexibility of the long frame machines. The jacking frame is designed as a modular system which allows for the use of different frame extensions. The special design of the BM 400LSC allows also to put the machine into a circular starting shaft. [...]

Hole Opener
The new developed extension tool Hole Opener allows for a millimetre accurate laying of pipes (also plastic pipes).
It is possible to use the Hole Opener system even in non displaceable soil and soft rock (up to 10 MPa) by combining it with the Front Steer […]

Front Steer for Guided Steel Pipe Drilling
Front Steer as a simple adaption to enhance the capability of existing unguided auger boring machines with a very simple navigation by inclinometer and elctronic hydrostatic water level. [...]

Front Steer
The new steering technology Front Steer enables pilot drillings in non-displaceable soil and soft rock up to a strenght of 10 MPa. [...]

Pilot drilling with active reamer
In ground, which allows for pilot drilling, but which is too dense to allow for the use of the standard reamer the use of an active reamer is possible. [...]

New Milestone in Guided Auger Boring
A novel steering technology from Bohrtec to extend the range of application of guided auger boring techniques was used for the first time in two pipe eating projects. [...]

Drainage Drilling for CityTunnel Leipzig - The Water Under Control
The performance of horizontal drainage drillings under seven meter ground water table and difficult ground conditions was a special challenge which was undertaken by the company Karo-San with a guided auger boring machine BM 400 from Bohrtec on the construction site of the CityTunnel Leipzig. [...]

Drainage dries up the Hoxberg
To minimise the future potential for landslips, the Hoxberg has been the focus of a challenging challenging pipe jacking project. This involved installing drainage pipes that run into a sewer in order to efficiently drain and permanently dry out the area at risk of major landslide. [...]
