The adjoining figure shows the longitudinal profile of the foundation down to a depth of 2 m. This information is based on a georadar measurement. The foundation's constitution can be validated analysing the shown core drill. The coloured encoding represents clean ballast (light grey), polluted ballast (dark grey) and silt (blue). (...)

This screenshot demonstrates the presentation of the foundation's longitudinal profile down to a depth of 2 m. Below the foundation layers several evaluations are shown. Parameters like wetness and bearing strength are rated through a three state encoding according to traffic lights. In this way, the bottom diagram illustrates the foundation's water drainage ability.. (...)
