Earthing Solutions
Vertical Rod – Efficient and Reliable GroundingSystems
Vertical rod grounding systems are among the most commonly used types of earthing, especially in areas with low to medium soil resistivity. These systems offer a practical and cost-effective solution for achieving the required earth resistance. The rods can be manufactured from various materials—such as copper-bonded steel, galvanized steel, or stainless steel—selected based on the soil’s chemical composition and environmental conditions. Proper selection ensures system durability, corrosion resistance, and long-term electrical performance.
Copper-bonded earth rods
The rods are manufactured from low carbon, high tensile steel with a 99.9% pure electrolytic copper thickness of 250 microns. Thread rolling after plating preserves the copper thickness en-suring corrosion resistance across the threads. Threads comply with ANSI/ASME B1.1-2003.
Extensible earth rods are coupled using thread-ed, easy to use brass couplings. Connections can be made by using bolted clamps or exother-mic welding process.
By specifying UL listed earth rods you ensure full compliance to the standard UL 467. Only products bearing the UL listing mark are cov-ered by UL’s listing and follow-up service.

Exothermic Welding
The exothermic welding process, also known as thermite welding and alumina-thermic welding is a simple, self-contained method of forming hight quality electrical connections of various metals such as coper to copper, copper to steel and steel to steel.

Mesh Grounding: The Practical Choice for High-Resistivity Soils
This solution is effective because a mesh grounding system increases the contact area with the soil, reducing overall resistance and providing a safer, more reliable path for fault currents—especially in high-resistivity soils where traditional rods or plates are less effective.
Earthing Enhancement Compounds
Marconite®
By adding MARCONITE instead of the sand and aggregate used in a standard concrete mix a highly conductive concrete is formed. Used as a backfill material around the earth electrodes, it provides a conductive medium increasing the surface area of the electrode and ensuring a highly conductive path between the earth electrode and the surrounding ground. Being a concrete it provides a permanent solution.
Bentonite®
BENTONITE is a moisture retaining clay consisting of sodium montmorillonite. By mixing BENTONITE with water the resultant slurry will swell to many times its original dry volume. When used as a backfill material, within a borehole earth system, it will continue to absorb water from the surrounding soil thus helping provide a stable earth resistance. This is also true when the clay is used to surround earth plates and lattice mats. It strongly adheres to the earth electrodes ensuring good electrical conductivity between the electrodes and surrounding ground.
Foundation Earthing: The Ultimate Solution for Safety and Equipotential Bonding
Because foundation earthing uses the building’s concrete-reinforced structure to create a large, low-impedance grounding system. This ensures broad equipotential bonding, minimizes step and touch voltages, and provides long-term stability and corrosion resistance.
Connecting Clamps for Reinforcements
In accordance with DIN 18014 “Earthing systems for buildings – Planning, execution and docu-mentation”, the equipotential bonding conduc-tor/foundation earth electrode must be con-nected to the reinforcement of the foundation slab every 2 metres.
For connecting reinforcing steel mesh or rein-forcements with round and flat conductors.
