Soil resistivity testing is a crucial process in assessing thee potential for corrosion in underground structures. It helps determinate the e electrical resistance of soil, which influences the e likelihood of corrosion existring on metal surfaces such as corrives, tanks, and cables.

Co to jest Soil Resistivity?

Soil resistivity measures how strongly soil opposis thee flow of electrical current. It i s expressed in ohm- meters (mbH · m). Low resistivity indicates high conductivity, incrowing the risk of corrosion, while high resistivity supplests lower corrosion potential.

Methods of Soil Resistivity Testing

Appliing Soil Resistivity Data

Resistivity values guides the design of corrosion protection systems. For example, areas with low resistivity may require more robutt cathodic protection or insulating measures to prevent metal defacation.
