Geothermal loop installation
As a geothermal drilling company, we handle the entire process from drilling to installation. After drilling the boreholes to the required depths, we install 32mm or 40mm geothermal loops using hydraulically powered loop winders. Our drillers mix thermal grout using our hydraulic or electric powered mixers to ensure the correct consistency, preventing future issues.
The borehole is then grouted from the base upwards using a pump and tremie method, which removes debris and seals the borehole against contamination. The thermal grout also enhances heat conduction between the earth and the pipework fluid.
All geothermal loops undergo rigorous air and hydro-static pressure tests before installation, with certificates provided as proof of reliability. Finally, we cut the loop to ground level, insert plastic soil pipes, and backfill with pea gravel to protect the loop before connecting it to the geothermal system.
