Site investigation using Robertson Geo wireline geophysical logging in test boreholes is available at all stages of the working life of the Dam:

Concept
Characterizing ground conditions for feasibility studies
Design
Ground investigation to feed into the design process
Build
Targeted ground investigation providing detailed data in key areas
Working Life
Routine monitoring
Events (e.g. overload)
Targeted evaluation of to assess condition or potential damage
Upgrade/Replacement
Investigation to feed into the decision making process
