Low-Impedance Electrical Earthing Grounding solutions for problem soils including rock
When facing a problem like electrical earthing in rock or design with problem geology. We have a solution that we feel will make your life easier when designing & dealing with High Voltage & Low Voltage electrical earthing system or grounding systems design compliance.
The problem
Granite, millstone, siltstone, sandstone, limestone and mudstone! All rock formations found in your area, and all types of rock that have a high electrical resistivity. Which can cause a real headache when designing/installing a High Voltage & Low Voltage electrical earthing systems.
The Answer
Electrical earthing rod – Chem-rod™. When installed the Chem-rod saturates the interfacing cylinder with naturally occurring electrolytes to solve even the most challenging of sites. A certain National Utility was so impressed, they invested in a 5-year evaluation with amazing results, up to 10 times the reduction in resistance when compared with traditional electrodes.
Applications
Efficient electrical earthing systems reduce the risk of electrical arcing and fires. The Chem-Rod improves reliability for many applications, including:
- Lightning protection systems
- Prevention of accidents caused by static charge and stray currents
- Protection of central communications, electronics, and AC power systems
- Meeting electrical grounding safety requirements for electrical substations
- Ground fault neutralization
- Safeguarding critical instrumentation and process-control equipment

The Chem-Rod uses advanced engineering to achieve a consistent, low-impedance electrical connection with the earth, even in unfavourable and varying ground conditions (like permafrost).
- Large surface area: The wider 25/8 inch diameter provides a larger surface area for a better connection to the earth.
- Electrolytic salts: In the presence of moisture, these salts dissolve and seep out of leach holes along the electrode. The salts continually increase the soil’s conductivity, further reducing impedance and resistance.
- Soil augmentation: Ground Augmentation Fill (GAF) is a combination of organic soil materials which optimize the conductivity of the soil around the Chem-Rod. In- creasing the amount of GAF can decrease the overall system resistance, increasing the system efficiency.
- Easy refills: Every Chem-Rod comes with a standard removable cap and access cover for easy maintenance of the ground salt charge.
- Optimised pigtail: The 2-foot long, 90mm2 stranded pigtail is exothermically welded to the body of the Chem-Rod.
