Who we are

Permanent Earthing Solution PES

At COMCO, we’ve pioneered PES—a groundbreaking conductive material that’s your ultimate solution for challenging grounding issues. Our innovation in permanent earthing has been put to the test, meeting the rigorous standards of IEC 62561-7 and IEEE 80-2000 Clause 14.5. We’ve introduced a new era of corrosion resistance and electrical performance previously missing in the industry.
PES sets a new benchmark for environmental responsibility too. It’s free from sulfur, sodium chloride, sulfuric acid, and hydrochloric acid—no harmful leaching, no pollution concerns. Compliant with stringent regulations, it’s trusted by both provincial and federal authorities.
With a resistivity of under 0.12 Ohm-m, PES is here to stay. It’s permanent, maintenance-free, and won’t wash away. No matter the soil conditions, it enhances grounding effectiveness. It’s your go-to solution for areas with poor conductivity—think rocky terrain, mountain peaks, or sandy soil.
Remember, whenever you need permanent earthing, PES shines. Whether it’s wrapped around the rod in an augured hole or enclosing grounding conductors in a trench, we’ve got your back.”

Renewable Energy

Energy is the future, make it brilliant.

Our Solution

PES Delivers Effective Results:

• Drastically reduces earth resistance and impedance measures.
• Typically boasts a resistivity of less than 0.12 Ohm-m.
• Once it takes its ‘set form,’ it maintains consistent resistance throughout the lifespan of the ground system.
• Excels in all soil conditions, ensuring performance even during dry spells

PES: User-Friendly and Versatile:

• Conveniently available in 25kg (55.11 lb) bags.
• Can be effortlessly installed either in its dry form or as a wet slurry.
• Offers the potential to downsize grounding systems in situations where conventional methods fall short.
• Embraces various installation methods, including the Trench Installation Method and Ground Rod Backfill Installation Method.”



What we offer


“At COMCO USA, we take pride in pioneering Earthing Solutions that have redefined electrical power earthing for over 15 years. Serving a diverse clientele spanning the electricity distribution, transmission, generation, and construction industries across the globe, we are renowned as frontrunners in this vital safety discipline. Our contributions have been instrumental in shaping industry standards, including the influential 41-24 and S34 standards.”

The Importance of Electrical Earthing

In an electrical network, the primary reason for implementing earthing is safety. When all metallic components within electrical equipment are properly grounded, it ensures that in case of insulation failure within the equipment, there are no hazardous voltages present in the equipment casing. If the live wire accidentally makes contact with the grounded case, it effectively creates a short circuit, causing the fuse to blow immediately. This action safeguards against the presence of dangerous voltages.

Our Journey in Advancing Electrical Earthing

At COMCO USA, we take immense pride in our legacy of pushing the boundaries in electrical power earthing for over 15 years. Our commitment to excellence has allowed us to serve a diverse clientele spanning the global electricity distribution, transmission, generation, and construction industries. We are recognized as leaders in this critical safety field and have played pivotal roles in shaping industry standards, including the influential 41-24 and S34 standards.

The Vital Importance of Electrical Earthing

To Ensure Human Safety, Protect Structures, and Safeguard Equipment: The primary purpose of electrical earthing is to preserve human life by preventing the danger of electrical shocks or fatalities, achieved by blowing a fuse. It establishes an alternate path for fault currents to flow safely, thereby eliminating risks to users. Furthermore, it shields buildings, machinery, and appliances during fault conditions, ensuring that all exposed conductive parts remain at a safe potential. Additionally, electrical earthing provides a secure pathway for dissipating lightning and short circuit currents, creating a stable platform for various applications.

PES and Environmental Responsibility

⦁ Soil-Friendly: PES has no adverse effects on soil, ensuring soil health.
⦁ Groundwater Protection: It does not leach ions or contaminate groundwater, preserving water quality.
⦁ Meets EPA Requirements: PES complies with Environmental Protection Authority (EPA) requirements for landfill use.
⦁ Safety Data Available: You can request the Material Safety Data Sheet (COM #786) from COMCO® for additional information on product safetyOur Warranty for Permanent Earthing
We guarantee that our maintenance-free  Environmental Protection Authority (EPA) requirements for landfill use.

The Permanence of PES  

⦁ Durable and Non-Leaching: PES does not dissolve, decompose, or leach over time, ensuring long-lasting performance.
⦁ No Periodic Treatments: It doesn’t require regular charging treatments or replacements, reducing maintenance efforts.
⦁ Maintenance-Free: Enjoy the convenience of a maintenance-free solution.
⦁ Not Dependent on Continuous Water: PES remains effective without the need for a constant water supply.
⦁ Resilience in Freezing Conditions: Even in freezing temperatures, resistivity increases by only 10-15 percent, demonstrating its durability.


(PES) will consistently deliver the required level of resistivity and maintain it over time. With PES, your investments are safeguarded as it protects the electrode, including copper rods. Feel free to contact us for more information and peace of mind

Your Ultimate Permanent Earthing

PES by COMCO USA represents a cutting-edge conductive material designed to resolve even your most challenging grounding issues. It has undergone third-party testing in accordance with IEC 62561-7, confirming that PES complies with IEEE 80-2000 standard Clause 14.5 on page 68. This standard marks a significant milestone in corrosion resistance and electrical performance, filling a longstanding gap in the industry.
PES distinguishes itself by being free from sulfur, sodium chloride, sulfuric acid, and hydrochloric acid—substances that can leach out and harm the environment. These elements are strictly prohibited by both provincial and federal authorities due to their potential to contaminate surrounding areas, including the water table. With a resistivity of less than 0.12 Ohm-m, PES is not only permanent but also maintenance-free, ensuring it never leaches or washes away.
Regardless of soil conditions, PES enhances grounding effectiveness, making it the ideal choice for areas with poor conductivity, such as rocky terrain, mountain peaks, or sandy soil.”

Features of PES



Conventional Earthing cannot meet the standard. PES is advance and as per I.E.E.E standard .Cost of installation is very high. PES is low cost and permanent solution Lengthy installation procedure Quick and easy installation This method require sulphuric acid, salts etc.They absorb and pollute the earth and water table.PES does not comprise any such materials And will not leach away with the passage of time.Limited durability PES is durable & permanent.Weather conditions adversely disturbs the resistivity level. PES maintains resistance level in any weather condition It require maintenance on regular basis PES is maintenance free. The resistivity level obtained first time will remain stable Soil condition with low resistivity is highly corrosive. Any conductor in dry soil will be deteriorated instantly PES protects conductor from any corrosion effects in any soil condition Moisture is highly required to maintain resistance, in a dry conditions. PES is free from any such conditions water. ESTIMATED OF PES FOR BACK FILLING AROUND ROD
