Soil Resistivity Testing Method -The Schlumberger Array

Schlumberger Array

The Schlumberger array is a geotechnical investigation method which determines the electrical resistivity of the soil. This is similar to the Wenner probe test, but it uses multiple current electrodes rather than just two. This allows for a more detailed and accurate measurement of soil resistivity. Soil resistivity testing carried out using different methods, this […]

Soil Resistivity Testing Method – Driven Rod

Driven Rod Method

The driven rod test is a geotechnical investigation method which determines the resistance of soil to the penetration of a rod or other penetrometer.  The Soil resistivity is determined using different Soil Resistivity Testing methods. However the Driven Rod, described below is the last of the three most popular Soil Resistivity Testing methods we use […]
