WebObtain soil samples from test holes and confirm the corrosion potential of soils to material types to be used for any subsurface structure. Report test results of laboratory analysis of soil. Typical laboratory testing includes pH, resistivity, sulfates, chlorides, and soluble salts. Use test results to determine corrosion potential of soil. WebSoil Resistivity Measurement Techniques. Soil electrical resistivity measurement might be carried out using different methods such as geological maps, seismic testing and ground penetrating radar. In these methods, the soil resistivity estimation is mainly based either on (i) electrodes spacing, or (ii) satellite imaging techniques [1].
