SPGS Earth Plus® Conductive Concrete

SPGS Earth Plus® conductive concrete will provide the low resistance ground that is essential to facility earth grounding system. Low earth ground resistance is now possible even where soil resistivity is high. SPGS Earth Plus® conductive concrete is economical, environmentally safe, and permanent.

Earth Plus® conductive concrete conforms to IEC Standard 62561-7 Lightning protection system components (LPSC) - Part 7: Requirements for earthing enchancing compounds. Part 7 specifies the requirements and tests required for earthing enhancing compounds producing low resistance of an earth termination system.

Earth Plus® conductive concrete has a resistance value around 20 Ohms per centimeter (cm). See chart below for typical soil resistivities.

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
