Enhance Earth Ground Resistivity With Earth Plus® Conductive Concrete
Earth Plus® Conductive Concrete is Safety Protection Grid Solution’s brand name for conductive concrete. Our Earth Plus® Conductive Concrete has a resistance value around 20 Ohms per centimeter (cm).
Why use Earth Plus® Conductive Concrete.
- Earth soil resistivity is typically high
- Earth Grounding System is required to have a very low Ohmic resistance value
- Compound area has a very small footprint
- Earth Ground System is required to be maintenance free
- Earth Ground System is required to be environmentally safe
- Copper electrodes is required to be protected
Where can Earth Plus® Conductive Concrete be used?
- Any type of soil including solid rock
How can Earth Plus® Conductive Concrete be installed?
- Dry
- Slurry mix
- In a trench
- In a hole
- Over conductors
How is can Earth Plus® Conductive Concrete made?
- Custom blend of Portland Cement and fine graphite powder that lowers the Ohmic value of the concrete.
