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.


ADVANTAGES GEOTHERMAL GROUT improves the efficiency and performance of ground source heat loop systems by matching the thermal conductivity of the surrounding soil and creating a permanent flexible seal to prevent aquifer contamination. Depending on site soil conditions, GEOTHERMAL GROUT can be mixed and adjusted to meet individual thermal conductivity requirements, improving the transfer of heat between the fluids circulated in the loop and the surrounding soil for optimum system performance.
