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.

  1. Earth soil resistivity is typically high
  2. Earth Grounding System is required to have a very low Ohmic resistance value
  3. Compound area has a very small footprint
  4. Earth Ground System is required to be maintenance free
  5. Earth Ground System is required to be environmentally safe
  6. Copper electrodes is required to be protected

Where can Earth Plus® Conductive Concrete be used?

  1. Any type of soil including solid rock

How can Earth Plus® Conductive Concrete be installed?

  1. Dry
  2. Slurry mix
  3. In a trench
  4. In a hole
  5. Over conductors

How is can Earth Plus® Conductive Concrete made?

  1. Custom blend of Portland Cement and fine graphite powder that lowers the Ohmic value of the concrete.

Note 1: Low resistivity soils are highly influenced by the presence of moisture

Note 2: Low resistivity soils are more corrosive than high resistivity soils
