Hydrotechnical structures monitoring

Thanks to investigation methods at our disposal and to a very long experience in the field (thousands of kilometers of GPR profiles), we are able to identify with high accuracy the structure and conditions of hydrotechnical complexes, such as dams, weirs, locks and flood barriers.

The study of the structural conditions of hydraulic complexes carried out exclusively on the basis of geognostic-geotechnical drillings results does not allow an objective assessment of the real situation throughout the whole development of the structure: the lithotechnical reconstruction by simple interpolation between boreholes does not allow for example to detect sinkholes, structure degradation, hydraulic fracturing, discontinuities caused by the presence of plants or rodents, frost line and natural weathering.

Concerning structural conditions monitoring in hydraulic complexes we purpose, in addition to GPR, seismic tomography, electrical tomography and conductometry.

Geopartner boasts of the first experiment in Poland for GPR underwater application: on behalf of Toruń Energy Department, through the use of a purpose-built bathyscaphe, was conducted a detailed study of the conditions of the concrete slab and the ground below at hydroelectric power plant in Włocławek. The results of this study open up new opportunities for the diagnosis of geotechnical and structural conditions of seemingly inaccessible areas of hydraulic structures. Other methods of investigation experienced in the past have proved to be too expensive or extremely complicated or unsatisfactory resolution; tests carried out have instead demonstrated the reliability of GPR method, mainly able to ensure analytical accuracy and an economic impact compatible with the monitoring goals of underwater portions of hydraulic structures.
