In the demanding terrain of the Snowy Mountains in NSW, CPTu testing delivers accurate subsurface data for geotechnical decision‑making.

Reliable drilling contractors in Cairns delivering geotechnical, sonic, environmental, and remote‑access drilling across Far North Queensland.

Brisbane’s Woolloongabba 2032 Arena project relies on Legion Drilling for critical geotechnical investigations. Their drilling data supports planning for the future Olympic venue.

Every Australian state requires licensed drillers for any bore that intersects groundwater. This protects aquifers, ensures safe construction and prevents contamination or long‑term structural failure.

"Our clients prioritize efficient rod handling and minimizing manual contact with drill rods," Hansen said. “The SRC30DT sonic rod carrier resolves 90 percent of these risks."

These training sessions are designed to help geotechnical engineers, environmental consultants, project managers, and field teams better understand how drilling methods, sampling conditions, and equipment capabilities directly affect sample quality, data reliability, and design decisions on site.

Dual tube direct push soil sampling provides the least disturbed core samples using a cased borehole to reduce chance of cross contamination.
