Our Engineering Geologists are experts in working out what lies beneath the ground, and in 3D too.
We are nationally sought-after leaders and the turn to people for engineering geology in complex sites, particularly in the Northland and East Coast regions. We have the geologists, and we know our country.
Slope Instability and Stabilisation Specialists
We excel in understanding the nature and causes of slope instability and can therefore offer practical remedial solutions. From small slips to major large-scale and deep-seated landslides – we can determine what makes them tick with surprising accuracy. We’ll identify, map and quantify geological risks, including active fault lines, so that you can plan with confidence.
Intelligent Geological Investigations
Getting the geology right for your project is essential, for efficient design and long-term performance. We can help with your geology jobs from identifying the ground they stand on, to designing specialised earthworks and landfill solutions for your future buildings.
