Ground Enhancement Material (GEM)

  • Maintains constant resistance for the life of the system once in its set form
  • Performs in all soil conditions even during dry spells
  • Does not require periodic charging treatments or placement
  • Does not require the continuous presence of water to maintain its conductivity
  • Fully sets within 3 days, fully cures within 28 days
  • Does not dissolve, decompose, or leach out with time
  • Non-corrosive
  • Reduces vandalism and theft since conductors are hard to remove from concrete
  • Easy-to-handle 25 lb (11.3kg) bags or buckets
  • Requires only one person to install
  • Exceeds IECĀ® 62561-7 which sets the benchmark for corrosion, leaching, sulfur content, and other environmental regulations
  • Complies to the United States Environmental Protection Agency (EPA) Toxicity Characteristic Leaching Procedure (TCLP), EPA test method 1311
  • Can be installed using trench or ground rod backfill methods


Ground Enhancement Material Specification

Ground enhancement material must be compliant to IEC 62561-7, must be permanent and maintenance-free (no recharging with salts or chemicals, which may be corrosive) and maintain its earth resistance with time. It must set up firmly and not dissolve or decompose, or otherwise pollute the soil or the local water table. It should not depend on the continuous presence of water to maintain its conductivity, and in its set form will have a festivity of not more than 2 ohm-cm.
