Corrosion is the gradual destruction of material – typically metals – caused by a chemical reaction with its environment. Corrosion degrades the useful properties of materials and structures including strength.

According to the National Association of Corrosion Engineers (NACE), there are multiple types of corrosion. Two of the most common for ground rod connections are soil corrosion and galvanic. Soil corrosion occurs when the chemicals within the soil interact with the ground rod metal, causing it to breakdown. Galvanic corrosion occurs when two dissimilar metals are in contact with each other and come in contact with water, causing both to breakdown. Galvanic corrosion is one of the most common types and typically the most destructive.

In 2002, The U.S. Federal Highway Administration released a study on the costs associated with metallic corrosion, that impacted nearly every U.S. industry sector. The results showed that metallic corrosion affected U.S. industries annually in the amount of $276 billion, with $1.1 billion of that in agriculture.


Grounding electrical charges protects against damage to machinery, buildings and personnel. Because corrosion is inevitable with ground rod connections, one way provide long-term protection against environmental corrosion and the disconnection of ground rod connections is to install the Strong Cap – a 3-in-1 kit from Strong Cap LLC.
