Company History…


cohistoryGeotech Drilling was founded by Gary Barnett (Marks father), when Gary bought our companies first Rig from ECNZ in 1990. At the time Gary was working with ECNZ when he helped design and build a rig capable of geotechnical investigation, originally for the transmission pylons. This rig was equipped with one of the first CPT’s in NZ, as well as hollow stem augers for the remote locations they were working in, because water was not always available.

From our companies formation, this first rig has been on many trucks and the equipment used has been constantly upgraded so as to stay at the front of the drilling market.

June 2007, Geotech was purchased by Mark and Mel Barnett whose desire was to carry on the successful family business.  Under this dynamic and youth ownership the business was destined to change.

In September 2007 new coring hollow stem augers were purchased from Foremost mobile USA to comply with the strict health and safety rules of most Environmental sites.
In July 2008 Geotech Drilling purchased new Nova Cordless CPT system along with Geosoft Interpretation software.

Mark has been drilling for as long as he can remember, he became a driller at the feet of his dad, and would love to share his knowledge and experience with his clients, both present and future clients.
