Achieving bore stability through highly fractured rocks and rubble
In addition to our standard geotechnical drilling services, Legion Drilling also offers specialised services to meet your unique project requirements. Our diamond drilling services are suitable for both geotechnical and exploration purposes, with conventional NMLC through to PQ3 Wireline drilling available. We also offer hydraulic packer testing with inflatable single and straddle packer systems, as well as vibrating wire piezometers and other geotechnical equipment for precision instrument installation.
Our capabilities extend to cone and piezocone penetration testing (CPT & CPTu), which provide precision geotechnical data and drilling capacity in a single machine. Legion Drilling also offers seismic CPTu (SCPTu) services, which measure both compression and shear wave velocities (Vp, Vs) in mine tailings and soils. Our flat dilatometer Marchetti test (DMT) is an in-situ test that is sensitive to soil stress history and compaction. At Legion Drilling geotech drilling company, our staff also provides electrical vane shear testing for the estimation of undrained and remoulded (residual) shear strength in clay and mine tailings.
At Legion Drilling, our geotech drillers adhere to the highest standards for equipment and methodology, including the Standard Penetration Test (SPT). We also offer Tubex and casing advance systems to achieve bore stability through highly fractured rocks and rubble. Contact us to discuss your geotechnical investigation or geotechnical drilling project and learn how our geotech drilling company can help you achieve your goals with our expertise and specialised geotechnical drilling services.
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.
