Model M5C San-Earth Conductive Concrete by Farwest Corrosion
Description
Developed in 1975 in Japan, SAN-EARTH M5C is the original conductive cement. When used in cathodic protection systems, it extends the life of the anode and reduces the overall cost. SAN-EARTH M5C doesn’t expand, shrink, or crack over time. It yields consistent performance and is both environmentally safe and maintenance free. It can be easily installed as a mortar, or as a slurry and, over time, it hardens to become conductive concrete. It helps protect water resources by sealing aquifer, aquitard, and aquiclude / confining layers and helps prevent cross-contamination. Unlike carbon coke, venting is not required as any gas that forms is on the outside surface of the hardened SAN-EARTH M5C. The current is dispersed over the large surface area reducing the breakdown reaction resulting in a smaller amount of gas bubbles which easily dissappate into the surrounding soil. This reduced reaction also allows the cathodic protection system to have a much longer life. SAN-EARTH M5C creates a special enviroment where the galvanic reaction with the anode is minimized.

Packaging
- 55lb (25kg) 4-Ply bags holding 0.827ft3 (0.02342m3) of SAN-EARTH M5C. 36 bags per pallet. 720 bags per 20ft container.
- 2000lb (907kg) super sacks holding 30.07ft3 (0.8516m3) of SAN-EARTH M5C
Storage, Transportation and Handling
Treat it the same as cement. Keep dry at all times. Keep away from moisture. SAN-EARTH M5C will harden after exposure to water. The SAN-EARTH M5C particle size is very small, so use of an approved dust mask is recommended.
Mixing Instructions
- MORTAR - SAN-EARTH M5C may be mixed with a small amount of water so that it forms a mortar that can be easily shaped. Slowly add clean water until desired consistency is reached.
- SLURRY - SAN-EARTH M5C may be mixed with a large amount of water so that it forms a slurry that can be easily poured or sprayed. Start with approximately 3 gallons (11L) of clean water per 55lb bag. Add additional water to reach desired consistancy.
Typical Vertical Installation
Auger the hole to the required depth. Lower MMO anodes to desired depth and make sure that they are centered in the hole. Pour or pump (slurry is recommended) SAN-EARTH M5C into hole around electrode making sure it reaches to the proper depth and that there are no air pockets or gaps. Make sure electrode is completely covered in SAN-EARTH M5C to protect it. The electrodes or connected cables should be insulated at any point where they exit or are not embedded in the SAN-EARTH M5C to help prevent corrosion. The chart below will help determine the amount of SAN-EARTH M5C that will be required.

Description
Invented and patented by Sankosha, SAN-EARTH® M5C is used to build conductive concrete grounding electrodes. SAN-EARTH M5C is manufactured in accordance with Sankosha's ISO 9001 Quality Standards. Independent third-party testing confirms that SAN-EARTH M5C meets IEC Standard 62561-7 (“Lightning Protection System Components (LPSC), Part 7: Requirements for Earthing Enhancing Compounds”) which specifies the requirements and tests for earthing enhancing compounds producing low resistance of an earth termination system. SAN-EARTH M5C electrodes are easily installed by spreading the dry powder in a strip over and around a counterpoise conductor in a horizontal trench. When the trench is refilled SAN-EARTH M5C absorbs moisture from the surrounding soil and hardens to become a conductive solid. The surface area of the electrode is dramatically increased, resistance to ground is substantially reduced and surge impedance is lowered significantly.
SAN-EARTH M5C is also effective in building vertical electrodes. Typically installed as a slurry around the electrode in a hole 3-6 inches in diameter, SAN-EARTH M5C ground enhancement material molds itself to the walls of the hole and hardens. Ideal contact with the surrounding soil is achieved and the diameter of the electrode effectively equals the diameter of the hole.
The consistent performance of SAN-EARTH M5C grounding systems has been monitored for 30 years. Independent testing has proven SAN-EARTH M5C is environmentally safe and has shown that SAN-EARTH M5C covered copper electrodes last ten times longer than bare copper ground wires.
SAN-EARTH M5C electrodes provide the low resistance ground that is essential to any lightning protection system. Good grounds are possible even where soil resistivity is high. SAN-EARTH M5C grounding electrodes are economical, environmentally safe and permanent.
