Invented and patented by Sankosha, SAN-EARTH is used to build conductive
concrete grounding electrodes. 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
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. Read the SAN-EARTH Technical Review for more details
about grounding with SAN-EARTH
SAN-EARTH 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 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 25 years. Independent testing
has proven SAN-EARTH is environmentally safe and has shown that SAN-EARTH covered copper electrodes last ten times
longer than bare copper ground wires.
SAN-EARTH 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
grounding electrodes are economical, environmentally safe and permanent.
