About us

For over 35 years Bohrtec, situated in Aachen, Germany, has been desiging and manufacturing machines for the trenchless construction of sewers.

All Bohrtec machines can be operated guided or non-guided. Compared to the conventional microtunnelling machines the guided auger boring machines are low-price, simple to use and have been steadily developed by Bohrtec over the last 35 years. Today these machines can be used in almost all ground conditions.

With all these machines the excavated ground is removed by augers which also transmit the torque from the rotary drive to the drilling head.

A solid and practical design characterises all Bohrtec machines which can also be equipped with a number of additional components:

Different drilling heads for different soil conditions and diameters.
Front Steer for guided auger boring in non-displaceable soil and rock.
Hole Opener for the precise trenchless laying of plastic pipes.
