ABSTRACT:
A cementitious Grout 111MG, with improved thermal and electrical conductivity over Grout 111, for use in at least one of geothermal heat pump systems and metal electrical grounding rod systems, with improved conductivity achieved by means of substituting metal grit for sand, a cementitious grout where both Grout 111MG and Grout 111 have mix water pH level limitations so as not to be corrosive to metals, a new use for Grout 111 as a fill material surrounding electrical grounding rods for enhanced electrical conductivity over traditional grouts, and a new use where both Grout 111MG and Grout 111 may be utilized to surround at least one of geothermal heat pump sub-surface heat transfer fluid conductive tubing/piping and electrical grounding rods installed within at least one of a well/borehole, a trench, and a pit.
