Key applications

  • Geotechnical & geological investigations: obtain high-quality rock and soil samples for accurate laboratory testing.
  • Construction projects: characterise subsurface conditions to inform foundation design and site planning.

Monitoring wells: install wells at precise depths for groundwater or environmental studies
