Vertical bore hole being drilled for Geothermal Both Drilling Rigs at work Geothermal supply and return pipe going to the building Fusing the Geo pipe together Drilling Rigs Sand and Grout that goes in the vertical bore holes for better thermal conductivity Drilling Rigs Again Geothermal pipe making our loops Sand and Grout going in the bore hole All the bore holes before being connected Fusing pipe from the building to the loop field Drilling more bore hole for vertical loops The loop field in progress The bore holes are drilled in parallel lines Work in progress
