Soil Resistivity Testing Method – The Wenner 4 Probe Test
Introduction to the Wenner 4 Probe Test The Wenner probe test is a geotechnical investigation method used to determine the electrical resistivity of the soil. Soil resistivity testing can be carried out using different methods. The Wenner 4 Probe test is one of the most common of these. Furthermore, its one of the three most […]
Soil Resistivity Testing Method -The 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
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
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 […]
Soil Resistivity Survey Methods – A few Short Videos
We receive a lot of questions asking how to do a Wenner test or what are the steps in a soil resistivity testing. The key thing to take away is that once you have the appropriate equipment. The act of ‘doing’ a Wenner Soil Resistivity Test is not that complicated. However, you must take a […]
Understanding Soil Resistivity & Soil Resistivity Testing Methods
Understanding Soil Resistivity is critical to Electrical Earthing System Design. Soil Resistivity Soil resistivity is a measure of how much the soil resists the flow of electricity. So an understanding of the soil resistivity and how it varies with depth in the soil is necessary to design the grounding – earthing system in an electrical […]
