Legion Drilling is a leading geotechnical drilling company dedicated to delivering comprehensive and specialized investigation services tailored to your project's unique requirements. Our extensive range of geotechnical services includes:
Diamond Drilling Services
We specialize in geotechnical investigations utilising a variety diamond drilling techniques. Our capabilities encompass conventional NMLC to HQ3 and PQ3 wireline drilling, ensuring high-precision results for our clients. Our experienced geotechnical drillers are adept at navigating complex subsurface conditions to provide accurate and reliable data essential for your project's success. With drilling rigs available in many configurations we have machines suitable for both limited access metropolitan sites and crawler mounted geotechnical drilling rigs for remote locations with poor infrastructure.
Hydraulic Packer Testing
Our hydraulic packer testing services employ inflatable single and straddle packer systems to assess the permeability and hydraulic properties of geological formations. This method is crucial for understanding groundwater flow and pressure conditions, which are vital for the design and safety of structures such as dams, tunnels, and foundations.
Geotechnical Instrumentation Installation Services
We offer precise installation of geotechnical instruments, including vibrating wire piezometers, to monitor pore water pressures, and other essential equipment to measure soil and rock behavior. Accurate instrumentation is fundamental for ongoing monitoring and assessment of site conditions, ensuring long-term structural integrity and safety.
Cone and Piezocone Penetration Testing (CPT & CPTu)
Our CPT and CPTu services provide detailed geotechnical data by measuring soil resistance and pore pressure during penetration. This technique delivers real-time information on soil stratigraphy, density, and strength, facilitating informed decision-making for foundation design and ground improvement strategies.
Seismic Cone Penetration Testing (SCPTu)
We conduct SCPTu to measure both compression (Vp) and shear wave (Vs) velocities in soils and mine tailings. This data is essential for evaluating soil stiffness, liquefaction potential, and seismic site response, which are critical factors in earthquake-prone regions and for dynamic loading conditions.
Flat Dilatometer Test (DMT) Service
Our flat dilatometer Marchetti test is an in-situ method sensitive to soil stress history and compaction. It provides valuable information on soil deformation properties, lateral stress, and shear strength parameters, aiding in the design of earth-retaining structures and embankments.
Geotechnical Electrical Vane Shear Testing
We offer electrical vane shear testing to estimate undrained and remoulded (residual) shear strength in clays and mine tailings. This test is particularly useful for assessing the stability of soft soils and tailings, informing safe and effective design and construction practices.
Standard Penetration Test (SPT)
Our geotechnical drillers adhere to the highest standards for equipment and methodology, including the Standard Penetration Test (SPT). SPT provides essential data on soil density and strength, which are critical parameters for foundation design and geotechnical analysis. We can provide SPT calibration tests for each of our drilling rigs upon request.
At Legion Drilling, we are committed to delivering precise and reliable geotechnical services that meet the highest industry standards. Our team of experts utilizes state-of-the-art equipment and methodologies to ensure the success of your geotechnical investigation or drilling project.

The list of new additions to our range of sonic and geotechnical rigs continues in Sydney. We just received Comacchio MC-T 405 truck and MC900 sonic geotechncal rigs for our Sydney depot. This means more unique options to compete your investigation and less time waiting to get your hands on the best rig for the job.
