LPI offers a selection of earth enhancing compounds for installation around earthing electrodes to reduce the earthing system impedance.

Our three most popular compounds are:

• SRIM (Soil Resistance Improvement Material) – a cementations, highly-conductive compound supplied in 20 kg bags. It is fully compliant with IEC 62561-7. It is suitable for all problem sites with moderate-to-high resistivity
• RESLO – an economical, betonies-based, specially-formulated compound supplied in 20 kg bags. It is best suited to problem sites with moderate soil resistivity, where underground watercourses, aquifers etc. do not predominate
• GRIP (Ground Resistance Improvement Powder) – supplied in 10 kg and 40 kg kits. It is effective in difficult sites, such as sandy soils and rocky ground.
