GEOTECHNICAL INVESTIGATION FIELD
Our geotechnical engineers are available to organize, supervise and carry out investigations including boreholes, trial pits, field tests throughout the country. The company is highly experienced in carrying out deep sampling boreholes using water drilling rigs and Wire-Line sampling instrumentation, as well as carrying out horizontal boreholes in tunnels. Boreholes that have been carried out during the excavation of Kallidromo tunnel were as deep as 515m using Wire-Line sampling instrumentation 95’’ in diameter. During drilling, various types of in situ tests are carried out (Maag and Lugeon tests, groundwater level monitoring etc.). The results are documented on daily borehole logs by our highly experienced scientific teams.
