GPS Ground Resistance Enhancement Minerals (GREM) provides the ability to substantially reduce soil resistivity in soils of the poorest electrical conductivity such as rocky ground or sandy soils. GREM comprises specifically selected compounds, which possess excellent electrical conductivity.

When GREM is mixed with water and poured onto the earthing system and surrounding soil the powder and water react to form a gelatinous hygroscopic mass which forms an integral part of the earthing system, this effectively increases the surface area of the earthing system in contact with surrounding soil. GREM will not wash away under seasonal conditions and therefore provides a permanent presence in working to improve and maintain the integrity of the earthing system. GREM is supplied in two seperate 5 Kg containers; one 5 Kg kit contains a copper compound (Copper Sulphate), whilst the other 5 Kg kit holds a mix of compounds which assist in the mixing process (Hardener).
