Soil Resistivity Testing Method – Driven Rod

Driven Rod Method

Soil Resistivity Testing Method – Driven Rod 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 […]

Why Greymatters Consultants Use CDGEGS HIFREQ Earth Modelling Software

Soil Resistivity Testing

Clients often ask us why we use CDEGS HIFREQ instead of XGSLab or, any of the other packages available in the market. And our usual response is simply. “It’s the market leading product (Top 1%)”. So, I thought it might be useful to quantify exactly why it is the leading product and also why it […]
