G&S’ Underground division is a leading provider of design, engineering, mechanical, electrical and structural maintenance services to the underground mining industry, with these services delivered across four key pillars: Longwall equipment, Development equipment, Spare parts and Site Services.

G&S’ Underground team have developed and operate under a clear mantra of being the “Safest set of hands” for their clients and in doing so, consistently deliver superior performance outcomes.

The safest set of hands mantra is based on the following 5 principles:

  1. We do not hurt anyone or expose them to harm on or off-site;
  2. We do what we say we will do and meet schedule timelines or better;
  3. Through a relentless focus on quality we maximise post overhaul/project availability;
  4. We put the customer first, we are agile and we over-communicate;
  5. We sustain our competitiveness through a focus on innovation and continuous improvement.
