How we work

We visit and assess the area for the proposed borehole. We obtain a geological report to ascertain ground conditions for heat pump boreholes. For waterwells we obtain a water prognosis report from the most appropriate hydrologists or use a more traditional method and dowse for water using a water diviner. We then supply you with a no-obligation quotation including a detailed analysis of how we would manage your project. With our own staff and equipment we drill the borehole and install all the necessary components, leaving you with your own water supply or ground loops ready for connection. We use some of the cleanest drilling techniques available and are leaders in technological development for the borehole and GSHP industries.
