Comparing the GIM Family
- GIM — carbon-base, polarization resistance above 8, for highly corrosive environments.
- GIM Light — a lighter variant (full technical content pending — see the product page).
- ECO GIM — clay-base, economical, a solid alternative to bentonite and traditional methods.
Applications
Industrial projects with corrosive soil, high-rise building earthing systems, and railway/metro infrastructure — anywhere durable earth-resistance reduction to IEC 62561-7 is required.
