What is another name for a concrete encased grounding electrode?

A concrete encased grounding electrode is commonly referred to as a Ufer ground. This term originates from the work of Herbert Ufer, who developed this grounding method in the 1940s. The Ufer ground typically consists of a grounding conductor that is encased in concrete, providing a low-resistance path to ground that is both durable and effective. The concrete itself enhances conductivity due to the electrolytic properties of the moisture within it, especially when it is in contact with a ground source.

This grounding technique is particularly advantageous in areas where soil conditions may not be ideal for other types of grounding methods. By utilizing the concrete encasement, the grounding system gains additional stability and resistance against corrosion, which can be a concern in traditional grounding methods like driven rods or plates. Understanding the Ufer ground's function and characteristics is essential for electricians and inspectors to ensure safe and compliant grounding practices.
