Are these changes a gradual erosion of standards due to competitive pressures, or a recalibration driven by evolving regulations and risk-based assessment?

These activities are subject to groundwater protection standards to prevent contamination and aquifer interference, even when licensing exemptions may apply.

Correct installation of vibrating wire piezometers (VWPs) is critical for reliable pore water pressure data.

With over 30 years of experience starting in electronics and calibration, Wassenaar explains why ground investigation is crucial for construction safety.

Some guidance on when you should take the plunge on a sonic rig for your next drilling program.

Conventional site investigations generate substantial quantities of waste, including contaminated soil, water, PVC wells, and single-use sampling consumables.

We are excited to present the 2nd Workshop on Advanced Technologies for Integral Contaminated Land Management, featuring an even larger delegation of North American experts for 2024.

Some of the most interesting and exciting drilling programs are completed from barges along Australia’s east coast lakes, rivers and harbours.

Bud Ivey will join us from Canada to discuss how hydrogeochemistry can guide in-situ remediation efforts and present new surfactant-based technology for PFAS recovery

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.

BOS 200® operates as a complete remediation system, utilising an activated carbon platform and is injected as a slurry at high pressure.

The publication has contributions from 50+ global experts from industry and academia . The objective was to give visibility to recent developments in the investigation and management of petroleum-impacted sites, as well as

Legion Drilling invited Eng. Diego Marchetti (Studio Prof. Marchetti) to present a webinar on in-situ testing using seismic profiling techniques (SCPTu-SDMT) for all our geotechnical and mining clients. Diego Marchetti shared his vast experience…

Our new Sydney Depot location provides greatly improved facilities for the support of our Geotechnical, Sonic and Geoprobe rigs and crews….

Sonic drilling rigs have emerged as innovative solutions for problems across multiple sectors of the larger drilling market, offering significant advantages for environmental, geotechnical, and mining applications. This article explores the benefits of using sonic drilling rigs, with a particular emphasis on their application in landfill, mine waste and tailings dam projects.
