Geotechnical data directly impacts the viability of your project. That’s why J&S Drilling has built a team of only the most committed and knowledgeable drillers. We seamlessly integrate with your workflows to deliver the most accurate, high-quality samples. Our geotechnical drilling services have formed the foundation of the most successful operations across Australia for over 40 years.
Environmental Drilling
Assess contamination with accurate data while minimising risks for successful site assessment and remediation. We provide expert drilling with care for the environment.
Marine Drilling
Certified marine jackup platforms and experienced marine teams ready to mobilise for challenging water environments. We conduct drilling, sampling and testing for coastal and marine projects.
Bore Maintenance
Keep your production, injection and monitoring bores performing at their peak. We offer maintenance services that extend the life of assets and reduce operational downtime.
Our Capabilities
Our superior drilling methods
Rotary air drilling
Fast penetration rates and precise rotary air control for deep investigations, monitoring programs, and preliminary site assessments.
Rotary mud drilling
Executes complex drilling programs with engineered drilling fluids that ensure superior borehole stability and precise control in challenging subsurface conditions.
Diamond core drilling
Drives detailed analysis with precision at diameter capabilities (NQ, HQ, PQ) for substantial sample volumes with high core recovery rates. Conventional coring (4C, 6C, 8C) is available.
Sonic drilling
Delivers superior samples with minimal disturbance. Our advanced high-frequency sonic technology enables continuous sampling across diverse formations and challenging project conditions.
Overburden systems
Penetrates unconsolidated materials with specialised overburden drilling systems designed for shallow investigations, site assessments, and access installations across various applications.
Direct push
Rapidly advance sampling tools and monitoring equipment through shallow formations using continuous advancement techniques.
Hollow & solid auger
Hollow stem augers enable simultaneous drilling and sampling, while solid augers provide rapid advancement through suitable formations.
Aircore / RC (reverse circulation)
Delivers accurate samples from the bit face to minimise cross-contamination through efficient air core and reverse circulation methods.
Sampling & Testing
