Geotechnical and geophysical surveys

Geotechnical and geophysical surveys:

• forecasting of soil conditions for various facilities;
• surveying for construction of various facilities;
• locating underground structures;
• seismic surveying;
• searching for ground water;
• environmental studies;
• identification of causes of damage to extended structures (oil and gas pipelines, rail- motorways).

Geophysical activities are performed using spectral seismic profiling method and equipment. Spectral seismic survey provides the following advantages:

• continuous tracking of geological boundaries;
• high definition and distance of survey;
• reliable identification of abnormal areas such as tectonic disturbances, cavities, floating layers, fracture areas and other underground structures;
• capability of subsequent survey for monitoring and verification purposes;
• capability of field software processing;
• mobility and flexibility in the course of field operations;
• relatively low cost of operations.

Geotechnical surveys (soil exploration) are required for:

• reconstruction of existing and construction of new facilities;
• monitoring of foundation soils of facilities in operation or under reconstruction;
• exploration drilling in confined spaces;
• application of express methods of soil conditions evaluation.

Field exploration of soil:

• static plate load test
• pressuremeter tests
• shear test
• static and dynamic probing

Hydrogeological surveys

• field geophysical and indicator techniques
