Where are surface groundbed anodes typically installed?

Surface groundbed anodes are typically installed 5-15 feet below the surface to maximize their effectiveness in providing cathodic protection. This depth helps to ensure consistent and effective electrical contact with the soil, which is essential for the operation of cathodic protection systems.

By being buried at this depth, the anodes can take advantage of the moisture and electrolyte present in the soil, allowing for better current distribution and reducing the resistance that electrical currents face.

Additionally, this depth protects the anodes from environmental factors such as freezing temperatures or physical damage from surface activities. It also helps maintain a stable temperature for the anodes, which is important for their longevity and efficiency in preventing corrosion in the connected metal structures.

In contrast, installing anodes at ground level, above ground, or at shallow depths (like 3-5 feet) does not provide the same level of protection and can negatively impact their operational effectiveness in a cathodic protection system.
