GeoThermal-Dynamic Drilling, Inc. 

Geo Thermal-Dynamic Drilling specializes in drilling vertical wells for residential and commercial geothermal heat pump applications. Our services include drilling boreholes for geothermal "loops", installation of loops, grouting the boreholes with thermally enhanced grout to further enhance the efficiency of the heat pump, trenching piping into the structure, and backfill and compacting of the trenches. Our thermally enhanced grout serves two purposes, first to enhance the thermal heat transfer with the surrounding soils, and second to ensure that the grout does not dry out and crack leaving voids in the borehole and destroying the thermal heat transfer. After the job is done we also provide a detailed wellfield layout, showing dimensions to each well and location of piping trenches. We also install a short length of rebar directly above each well, but a few inches below grade, to give a second method for locating wells utilizing a metal detector.
