Bore hole sounding

Bore hole soundings are carried out by means of auger drilling and jetting.
This process consists of the sectional drilling of the points to be checked using plastic piping and the subsequent release from regulatory control. With this process bore holes with a depth of down to 30.0 m can be achieved.
The probes are lowered down into the bore hole, creating a continuous diagram. This process can be carried out manually as well as computer-aided.
The key objective of bore hole soundings consists of the release of drilling points for the establishment of shoring shafts as well as for the insertion of supporting braces. Thus, accidents during the installation of the shoring due to exploding bombs are impossible.
The method also serves to examine sites where unexploded bombs are suspected.
