Void hunting with Meridian Energy: why ERT was the right tool for the job

1/1

The challenge for Meridian Energy was to fully understand site geology beneath a proposed wind turbine farm in the Hawke's Bay Ranges.

RDCL used Electrical Resistivity Tomography (ERT) to map areas of limestone and interpret voids within highly variable ground across an area approximately 25 square kilometres.

Our geophysics field team tackled rough terrain and physically demanding conditions for three months to deliver a highly valuable dataset.

 

Geological data, including the identification of voids, was then fed into engineering models to reduce risk during the construction phase.
