From October 2014 to January 2015 the GEO-BOHRTECHNIK GmbH was involved in the preparation of the excavation for the test tower Rottweil.

For the prestige project 200 soil nails were drilled to create a shotcrete shoring. Furthermore surveying holes were drilled on the sole of the pit in order to explore the cavities. The diameter of the pit was 50m and the depth was 25m. Click here to get information about the current state of the construction.
