Wenner 4-Point Testing

Soil resistivity testing is the cornerstone for building a solid site design or when conducting a GPR study. Knowing how conductive or resistive the soil is can be critical. A properly conducted soil resistivity test arms one with the information needed to ensure the safety of equipment and personnel when building your site. A proper soil resistivity test can also save valuable time and money. It takes the guesswork out of the construction and design process and gives a predictable outcome. The most reliable and widely accepted soil resistivity test in the world today is the Wenner 4-point Test Method.

The Wenner 4-point Soil Resistivity test is conducted by using 4 probes spaced at equal distances across the surface of the earth in a straight line. The distance that the probes are spaced is approximate to the depth into the soil that the test will read. Multiple tests are typically conducted at a variety of probe spacing. The resultant data can then be entered into specialized computer software and specific resistivity reading at various depths can be calculated.

E&S Grounding Solutions has the equipment, software, and experience needed to properly perform soil resistivity testing. Utilizing the Wenner 4-point Test Method, E&S can accurately model the electrical resistance characteristics of the soil at your site. Our trained technicians know where and how to conduct the tests so that the minimum amount of electrical interference will not affect the test results at your site. With the correct soil resistivity information, you now have the tool needed to build a safe and cost-effective design.
