GROUNDING GROUT is a high-solids, single-component bentonite grout. GROUNDING GROUT is specially formulated to provide a conductive seal around grounding rods. When used to seal drilled boreholes in which vertical grounding rods are placed, GROUNDING GROUT increases the grounding system’s conductivity by lowering the resistivity from 300 ohms/meter with normal soil to 0.76 ohms/meter. GROUNDING GROUT adheres to the entire surface of the grounding rod, providing the smallest surface area and, consequently, offering the greatest effective resistance area. This helps to stabilize the ground resistance despite seasonal changes in temperature and soil moisture content.
