SAN-EARTH M5C Conductive Cement for Grounding Systems

http://www.sankosha-usa.com/sanearth.asp

SAN-EARTH is used to build Conductive Concrete Grounding Electrodes.

SAN-EARTH absorbs moisture from the surrounding soil
and hardens to become a Conductive Solid.

SAN-EARTH covered Copper Electrodes last ten times longer
than Bare Copper Ground Wwires.

Note - The surface area of the Electrode is dramatically
increased, Resistance to Ground is substantially reduced
and surge Impedance is lowered significantly.

SAN-EARTH Electrodes provide the low Resistance Ground
that is essential to any Lightning Protection System.

I'm sure you can roll your own conductive cement, just like you can
build something that is patented. Selling your own conductive cement
would be another story.

As a side note, when you deal with sheets of conductive material, the
term sheet resistance (Doh!) comes into play. This is really common in
chip design where you roll your own resistors. However, getting back
to the cement, even though the copper wire is much lower resistance
than the carbon embedded cement, the cement makes up for it with
greater contact to the soil.

If you watch construction in expensive areas (i.e. where you don't
have land to waste), the engineers use what is generally known as
geotex. They place the dirt in layers with geotex in between layers in
such a manner where the slope can be steeper than is just soil was
used. Well, I had a hunch and sure enough they have conductive geotex

It gets a bit messy since some refer to heat conductivity rather than
electrical conductivity.

I most places with poor soil conductivity, they just use a
counterpoise. You can often see the radials from satellite
photographs. I have a few documented he
