|Each activity will be documented entirely. Precise sampling and reports of our drilling team on the spot are the prerequisites for the comprehensive evaluation following completion of the work. Experienced and theoretically well-trained operators know what is important and what must be recorded. Layer specifications, pump diagrams and structural drawings are collected and evaluated using special software and CAD.
Logger supported pump trials during which the most important parameters are automatically recorded over a longer period of time as well as sieve analyses which can be carried out on the spot if required, are a matter of course for Vormann in order to determine the ideal grain size for the filter gravel filling.
All measurement results of cone penetration tests such as peak resistance and skin friction are promptly recorded electronically and provided to the customer for further processing. We undergo these efforts so that the customer is finally satisfied with our work and see clearly on his computer what we found and what we did. For our work is a matter of trust and we do not want to betray our customers' trust.
