Environmental Drilling

Our methods

Sonic drilling

Achieve superior sample quality with advanced high-frequency sonic technology and continuous sampling through contaminated formations, while preventing cross-contamination.

Direct push

Advance sampling tools and monitoring equipment through shallow contaminated formations. Ideal for rapid environmental site characterisation and emergency response investigations.

Auger hollow & solid flight

Conduct shallow environmental investigations, install monitoring bores and gas vapour wells with hollow stem augers that prevent contamination of underlying formations.

Sampling & Testing

Critical data collection

Determine in-situ soil properties with precision and reliability. Environmental partners trust us to deliver reliable and accurate samples.

  • Sonic sampling – single / dual wall: Superior sample recovery with minimal disturbance
  • Dennison sampler: High-quality undisturbed sampling techniques
  • Hollow-stem auger systems
  • Water sampling
  • Direct Push sampling

client reviews

Heard on site

“On behalf of KNPL, your team has done a incredible job. The level of professionalism, pride and care factor the team has shown in their work has been outstanding. It’s been a pleasure to see how consistently high standards are maintained, both in quality of work delivered and in the way the team carry themselves each day. The commitment to safety and the strong team culture you have at J&S is equally as commendable. Thank you for creating a safe and supportive work environment and delivering us a safe and successful drill program. Much appreciated.”
“I would like to take the time to thank you for the work that was completed at our home. The crew that completed the drilling were exceptional, they explained the complete process and did it without fuss. I think I’ve learnt a little about drilling myself or at least more than you thought I did. Once again thank you I will certainly be very happy to recommend you to anyone.”
