Geothermal Industries Australia (GIA) was engaged by a residential plumbing contractor to deliver the geothermal drilling scope for a substantial residential project in Burraneer, NSW. The project required drilling 18 geothermal probes to a depth of 135 metres each on a notoriously tough site. Burraneer’s coastal geology presented significant challenges, including shallow sandstone, clay lenses, and unexpected groundwater inflows that complicated drilling operations. Despite these difficult conditions, GIA’s experienced team deployed advanced drilling techniques and real‑time geological logging to navigate the subsurface variability. Working within a constrained residential footprint, our team successfully completed all 18 boreholes to the full 135‑metre specification while protecting adjacent structures and maintaining a clean, safe worksite.
For this installation, GIA utilised our 45DN Muovitech Turbo pipe as the geothermal probe material. The 45DN diameter was selected for its superior thermal transfer characteristics and hydraulic efficiency over the 135‑metre depth. Muovitech Turbo pipe’s robust construction, enhanced burst pressure ratings, and resistance to deformation proved invaluable given the tough ground conditions encountered in Burraneer. Each of the 18 probes was carefully installed, thermally grouted to maximise ground contact, and pressure‑tested to verify system integrity. The combination of GIA’s drilling precision and the high‑performance Muovitech Turbo pipe delivered a durable, energy‑efficient geothermal loop field that will serve the residence reliably for decades.
Finally, GIA extends its sincere thanks to the residential plumbing contractor for engaging us as their trusted drilling partner on this challenging Burraneer project. Their confidence in GIA’s ability to deliver on a tough site was instrumental to the project’s success. We look forward to future opportunities to work alongside them on demanding residential geothermal installations across the Sutherland Shire and beyond.
