Geotechnical Drilling Services

Geotechnical Drilling

Geotechnical drilling is carried out to determine soil and rock characteristics and groundwater tables. 

As leaders in the geotechnical drilling field in New Zealand, our team of specialists regularly encounter major fault lines, glacial valleys and volcanic materials. This means that difficult drilling conditions are all in a days work, and any problems arising are quickly overcome. This is just one of the reasons why we are New Zealand’s only ‘result driven geotechnical drilling specialists’.
