This was a project for the Council of State Governments building renovation. We initially drilled (2) 300′ geothermal test wells and grouted the wells with thermally enhanced bentonite grout. We also performed a thermal conductivity test on one of the wells. A little bit later, we drilled the remainder of the well field, which consisted of (56) 300′ geothermal bore holes. Each well was grouted with thermally enhanced bentonite grout.
