In arid regions located on metamorphic rock-type geology, the weathered bedrock generally doesn’t contain groundwater anymore. In this case, people can be forced to extract water contained in the unweathered rock at large depth.

In sedimentary geology, the groundwater is generally located in ground water tables. Depending on the soil/rock porosity, soil/rock permeability and sometime fracture and karstic network, the number of ground water table, their thickness and their spatial heterogeneity may vary greatly.

In coastal areas, the multiplication of groundwater pumping can sometime modify the natural salt water wedge and create salted water intrusion under land area. This intrusion may have a catastrophic impact on water resource, agriculture and industry.

The location and temporal extension of soil pollution is of paramount importance for land-use planning, agriculture, water resources and soil depollution. According to the type of pollution, electrical resistivity or induced polarization can be linked to the presence of pollutants.

Waste disposal are objects that need to remain under supervision during their whole lifetime. The first aspect of this supervision consists in checking the proper containment of wastes to avoid lixivia’s leak through the geomembrane and through the possible clayey layers. The second aspect deals with the monitoring of the homogeneous circulation of lixivia in the waste disposal to ensure an optimal degradation.

During archeological studies, the determination of the location and of the spatial extension of the buried structures (e.g. walls of ancient buildings) allows to determine precisely the area of investigation and the geometry of the buried structure. Electrical resistivity has been shown useful to image remains of buildings, graves and other traces of ancient human activity.

Cavities generally occurring in calcareous soils (karst) or due to mining activity may constitute a real danger for all type of activity on the ground surface. The cavity may create ground surface subsidence to sinkhole, generating from fissure in the masonry to the total collapse of building. This phenomenon can also occur in dams. In all cases, the early detection of cavity is the only way to minimize risk for population and structures. Usually employed complementarily to other methods, the electrical resistivity tomography may be sensitive to the presence of cavities.

Landslide is one of the major natural hazard in the world. Whether ancient and reactivated or recently triggered, the knowledge of the slip surface depth and geometry allow to estimate the landslide volume to analyze the risk for population and buildings.

Geotechnics can benefit greatly from geophysics. It can be used to identify different contrasted soil layers, to position drillings, to detect depth of foundations or to monitor soil remediation work such as resign infiltration.

For mining exploration applications, the method and equipment to use depend on how the precious metal is concentrated or disseminated in rocks, on the size of the orebody but also on its depth.

All areas of the country, whether urban or not, have needs for irrigation, water supply, fire protection, forest protection, etc. To cover the above water storage-storage needs, our company can propose from the wide range of sizes and canopies that has the appropriate solution for each application in regions and municipalities. The size of the tank depends on the needs for the application that is addressed and the available space. Our company manufactures metal water tanks in a variety of dimensions and capacities. So it can supply you with water tanks from 5m³ up to 1600m³.

What it is : It is a photovoltaic system that pumps water whenever there is sunshine. No batteries with zero consumables and operating costs.

How it works and what parts it consists of : The principle of operation is based on Inverter technology (frequency adjustment Hz) so that the performance is adjusted according to the sunshine.
