About NZDrill
We specialize in geotechnical site investigations to support a wide range of engineering and construction projects — including residential, commercial, roading, and infrastructure developments.
Our core services include:
Services
Cone Penetration Testing (CPT)
In-situ testing used to determine soil stratigraphy, strength, and deformation characteristics.
Our CPT investigations are carried out with a focus on efficiency, accuracy, and minimal site impact.
Data is recorded continuously during testing, allowing for clear subsurface interpretation and timely delivery of results.
Percussion Drilling & Soakage Testing
Drilling to assess subsurface soakage capacity, permeability, and the presence of rock or low-permeability layers.
We carry out soakage testing using percussion-drilled boreholes, allowing us to assess infiltration rates and subsurface conditions with minimal disturbance.
Our team is familiar with a wide range of ground profiles, including sites with variable soil layers and weathered rock.
Machine Borehole Drilling & Sampling​
In-situ testing used to determine soil stratigraphy, strength, and deformation characteristics.
Our CPT investigations are carried out with a focus on efficiency, accuracy, and minimal site impact.
Data is recorded continuously during testing, allowing for clear subsurface interpretation and timely delivery of results.
