In the absence of any previous ground investigation, what lies below our feet is like a big black box.
Drilling a borehole, obtaining a Cone Penetration Test (CPT), or performing other invasive techniques will supply accurate ground information at specific point locations, BUT the rest of the ground is still widely unknown terrain.
By having our Geophysics team investigate and provide geophysical profiles, you will complement any necessary invasive investigations by having larger-scale ground information and variations.
At Cook Costello, we believe the best way to serve our clients is by giving them the best understanding possible of their site.
We work closely with our clients, making a point to discuss the goals of the investigation and any potential limitations in our detailed proposal. We also gather all possible local and regional information to fully understand each site, its condition, and access. Finally, we supply all this information, and our findings, in a detailed report.
Our services can be accessed throughout New Zealand, for a wide variety of projects. We are a multi-disciplinary company so we can provide the whole package at a competitive price.

This investigation aimed to assess the structural integrity of stopbanks using several geophysical techniques.
A new development in a previously unused area of a cemetery requires clarity on the existence of potential unmarked graves.
The purpose of this project was to investigate the presence of, and map, potential voids underneath the working level of an active quarry.
Our expert team determined the location, depth and extent of a historic landfill to correctly lay a pipeline.
The amount of geophysical information we gathered allowed us to interpolate the interpreted depth to groundwater and depth to basalt.
From the GPR results, targeted invasive tests could be planned to accurately determine the extent and damage from the voids.
