Marine
Our specialist drilling and testing services cover marine environments, rail networks, and remote sites, including helicopter access. We provide comprehensive site investigations, soft marine soil sampling including sonic drilling, and the patented Aqualock soil sampling system for marine and alluvial deposits along with all our other drilling and testing technics, ensuring accurate data for your critical infrastructure projects.
Our experienced teams and specialised equipment overcome logistical hurdles to deliver reliable results, no matter the terrain. From offshore platforms to remote rail corridors, trust us for your complex drilling and testing needs.
Rail
Geotechnical drilling is vital for KiwiRail's network stability and safety, particularly in New Zealand's challenging terrain. Griffiths Drilling, with its specialized light-weight rigs, is a key partner. These compact rigs are essential for accessing remote, steep, and logistically difficult areas along the rail corridor where traditional, heavy machinery can't operate. They perform critical tasks like soil sampling, installing monitoring instruments (piezometers and inclinometers), and conducting in-situ tests like Standard Penetration Tests (SPT) to assess ground conditions. This data informs KiwiRail on slope stability and foundation design, ensuring the network remains resilient against geological hazards like slips and earthquakes.
Remote Access
Geotechnical drilling in remote, inaccessible areas often requires heliportable rigs, which are broken down into lightweight modules for helicopter transport. This capability is crucial for projects like landslide investigations or infrastructure development in mountainous or forested terrain. Griffiths Drilling excels in this niche, utilizing their specialized light-weight rigs to overcome logistical hurdles. These compact, yet powerful rigs can be flown piece-by-piece to a precise location and then quickly reassembled. This allows Griffiths to perform essential tasks such as soil and rock coring, in-situ testing, and instrumentation installation, all in locations that would be otherwise impossible to access with traditional heavy machinery.
