Geothermal Drilling by GeoCon is undertaken to facilitate the installation of geothermal ground loops (ground collectors) as part of any ground source heat pump system. GeoCon undertake Geothermal Drilling, ground loop installation, subsequent backfill with a thermal enhanced bentonite grout (this gives a greater thermal conductivity than a regular civil engineering grade grout), pressure test and flow test on each loop and subsequent sign off, where we sign off each geothermal borehole as completed with ground loop correctly installed.
As part of our service we can also provide test holes for larger projects with thermal testing to give a preliminary indication as to the thermal properties of the ground. This should confirm the findings of the geothermal desk study and can help to reduced the number of holes required.
Drilling is facilitated via rotary open hole drilling methods using techniques such as air mist and water flush.
Our drillers are BDA accredited and are very experienced in Geothermal drilling.
