The Ufer Ground is an electrical earth grounding
Ground (electricity)

In electrical engineering, ground or earth may be the reference point in an electrical circuit from which other voltages are measured, or a common return path for electric current, or a direct physical connection to the Earth....
 method named after Herbert G. Ufer, who developed the technique during during World War II in Arizona. A synonymous term is "concrete encased ground electrode". It is installed by connecting the ground wire to the steel reinforcement bars
Rebar

A rebar, or reinforcing bar, is a common steel bar, and is commonly used in reinforced concrete and reinforced masonry structures. It is usually formed from carbon steel, and is given ridges for better mechanical anchoring into the concrete....
 in foundation concrete, or by embedding a length of wire in the foundation near the bottom of the concrete. Its effectiveness is based on the idea that concrete is more conductive than most soil, and this semiconducting characteristic increases surface area contact with the soil the foundation is built on.

An Ufer ground of specified minimum dimensions is recognized by the U.S.
