ELECTRICAL RESISTIVITY

Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is a fundamental property that quantifies how strongly a given material opposes the flow of electric current. This method is based on the measurement of the electrical resistance of the soil from its surface to great depths through an array of electrodes used to channel the current to the ground and measure the potential generated by this current at the same time.

The measurements require special geophysical equipment and extensive experience. These are applied in many areas such as:

• Water research
• Research on minerals
• Geotechnical research
• Investigation of invisible faults
• Research for support of geotechnical studies (foundations, bridges, tunnels, roads, etc.).
• And many others

GEOSERVICE has a lot of experience with these measurements since it has been practicing for over 25 years (since 1988) and a record of thousands of measurements from every part of Greece. It uses equipment from ABEM SA and can carry out measurements that derive information on depths of 200 meters below the ground.
