Description of Service
1. DC-Geoeletric
A geoelectrical measurement is carried out by recording the electrical potential arising from current input into the ground with the purpose of achieving information on the resistivity structure in the ground. In a homogeneous ground (halfspace) the current flow radially out from the current source and the arising equipotential surfaces (red surfaces) run perpendicular to the current flow lines (blue lines) and form half spheres.
Applications
- Mineral exploration
- Groundwater
- Geophysical-Archaeology
- Cavities detection
- Geotechnical Investigation
2. Ground Penetrating Radar (GPR)
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR uses high-frequency (usually polarized) radio waves, usually in the range 10 MHz to 2.6 GHz. A GPR transmitter (Tx) emits electromagnetic energy into the ground. When the energy encounters a buried object or a boundary between materials having different permittivities, it may be reflected or refracted or scattered back to the surface. A receiving antenna (Rx) can then record the variations in the return signal.
