terratec has worked on geotechnical projects for hydro power, mining, road construction, etc.
We have used surface geophysical and borehole geophysical methodes to solve the problems brought to us by the client. Some of our services are listed below.
Geophysics applied to dams
Major applications:
Studies:
- support for the cartography of the basement.
- localization of fracture and fault zones.
- determination of direction and dip of fracture and faults
During construction:
- control of injections
- control of density
Monitoring of the existing dams:
- repetitive control of the underground downstream of the dam and the dam itself, even for the detection of the escapes (before and after the flooding)
- control of the argillaceous core
