Our Capabilities
Our 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 / reverse circulatio
Delivers accurate samples from the bit face to minimise cross-contamination through efficient air core and reverse circulation methods.

Instrumentation
Instrumentation capabilities
Maintain optimal performance, obtain accurate data and manage associated risks through highly sensitive geotechnical instrumentation by one of the leading drilling companies in Western Australia.
Vibrating wire piezometers (VWPs)
Precision pore water pressure monitoring for dams, embankments, foundations, tunnels, and slopes. Long-term groundwater condition and monitoring with measurements for hydrogeological evaluation.
Inclinometers & extensometers
Real-time monitoring of lateral movement and vertical displacement in retaining walls, slopes, and deep excavations. Critical for early warning systems and construction quality control.
Shape arrays
3D deformation monitoring for complex structures and geotechnical elements. Continuous measurement of bending, displacement, and shape changes.
Multi-point borehole extensometers
Deep subsurface settlement monitoring at multiple elevations within single boreholes. Essential for tracking ground movement, heaving, and layer-specific deformation in complex geological conditions.
Standpipe piezometers
Pore water pressure measurement for routine groundwater monitoring. Reliable long-term performance for construction dewatering, slope stability and environmental compliance programs.
Gas monitoring wells
Subsurface gas concentration monitoring for methane, CO2, radon, and VOCs. Essential for landfill management, environmental remediation, and hazardous gas detection compliance.
Settlement monitoring points
Surface and structural settlement tracking for infrastructure monitoring. Precise vertical displacement measurement for buildings, bridges, roads, and critical facilities.
