Geophysics is a non-invasive, low-cost way of discovering what lies below the surface. Our surveys can be performed for projects that need an understanding of what is underground, such as geological features, the water table, or even hidden voids like undisclosed gravesites.

Geophysical Methods

Our team can combine geophysics with intrusive methods in order to provide our clients with the optimum amount of information in a cost-effective package.

Add Colour to Your Ground Investigation

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.

How can our Geophysics team help you?

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.

Get in touch with our team, we’d love to hear from you.
