What does a geologist do at Heidelberg Materials?
Heidelberg Materials is one of the world's largest manufacturers of building materials and, in addition to cement, also sells aggregates such as sand, gravel, stone chippings and crushed stones. The mineral raw materials for the various building materials are extracted and processed in the Heidelberg Materials own quarries and opencast mines around the world.
My job as a geologist is to carry out the geological and raw material investigations required beforehand through boreholes and to evaluate them in a model. Before an approval procedure for mining can be initiated, there must be a proof that the respective raw materials, e.g. sand, gravel and hard rock, are also available in the sufficient quality and required quantity. The high investments that are needed for the extraction and the processing need to produce standard and certified concrete, mortar or asphalt products in the end.
Many rock samples can be taken from the drilled meters. They are then transported from the investigation field to various building materials laboratories. Spontaneity, flexibility and improvisation are often required.
