Product catalog summary
Overview: The nVent ERICO Ground Enhancement Material (GEM) is a carbon-based conductive material designed to improve grounding effectiveness, particularly in challenging soil conditions. It is maintenance-free, long-lasting, easy to use, and environmentally sensitive.
Key Features:
  • Effectiveness: Reduces earth resistance and impedance, maintains constant resistance, and performs well in all soil conditions.
  • Maintenance-Free: No need for periodic treatments or continuous water presence.
  • Longevity: Sets within 3 days, cures in 28 days, and is non-corrosive.
  • Ease of Use: Available in 25 lb bags or buckets, requiring only one person for installation.
  • Environmental Compliance: Exceeds IEC 62561-7 standards and is EPA compliant.
Installation Instructions:
  • Trench Installation: Mix GEM into a slurry, spread in trench, place conductor, cover with GEM, and backfill with soil.
  • Ground Rod Backfill Installation: Auger hole, place ground rod, premix GEM, pour around rod, and backfill with soil.
Specifications:
  • Standards Compliance: IEC 62561-7 and EPA TCLP.
  • Leaching Limits: Specific limits for arsenic, barium, cadmium, chromium, lead, mercury, and selenium.
  • Resistivity: Less than 2 Ω-cm for powder and less than 20 Ω-cm for mixed material.
  • Corrosion Performance: Specific polarization resistance for copper-plated and galvanized electrodes.
  • Strength: Flexural strength of 300-450 psi and compressive strength of 100-200 psi.
Ordering Information: GEM is available in 25 lb bags or buckets. Contact local nVent ERICO sales representatives for quotes.
Customer Support: Support is available for product or application questions through nVent's website.

nVent ERICO Ground Enhancement Material (GEM) is the effective, maintenance-free, long-lasting, easy to use, and environmentally sensitive solution to your toughest grounding problems. GEM is a low-resistance, non-corrosive, carbon-based superior conductive material that improves grounding effectiveness, especially in areas of poor conductivity such as rocky ground, mountain tops and sandy soil. GEM is also the answer in situations where ground rods can't be driven or where limited land area makes adequate grounding difficult with conventional methods. GEM contains portland cement, which sets...

1. Auger a 3-inch (7.5 cm) or larger diameter hole to a depth of 6 inches (15 cm) shorter than the length of the ground rod. 2. Place ground rod into augered hole and drive 1 foot (30 cm) (if possible) into bottom of the hole. The top of the ground rod will be approximately 6 inches (15 cm) below grade. At this time, make any connections to ground rod using CADWELD® connections. (See Note 1) 3. Premix GEM into a slurry form. Use 1.5 to 2 gallons (5.7 to 7.6 liters) of clean-potable water per bag or bucket of GEM. The installation of GEM in a dry state is acceptable for vertical ground rod applications....
