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 the 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.
