Ground Enhancement Material (GEM) Now Conforms to IEC 62561-7 Standard
ERICO offers Ground Enhancement Material (GEM) – a superior conductive material that solves your toughest grounding problems. Third party testing has been completed to verify that GEM conforms to IEC 62561-7. This new standard introduces a benchmark for corrosion and electrical performance that has been absent from the industry to date.
GEM is a low-resistance, non-corrosive, carbon dust-based material that improves grounding effectiveness, especially in areas of poor conductivity. Its resistivity factor is less than
2 ohm-cm, which is less than 1% the resistivity value for bentonite clay.
GEM contains portland cement, which hardens when set, to become a conductive concrete that is permanent, maintenance-free and will never leach or wash away. GEM improves grounding effectiveness regardless of soil conditions.
It is the ideal material to use in areas of poor conductivity, such as rocky ground, mountain tops and sandy soil.
