Geophysics
Comprehensive Geophysical Services in New Zealand
Geophysics offers a non-invasive, cost-effective solution for uncovering what lies beneath the surface. Our geophysical surveys are ideal for projects requiring a clear understanding of subsurface conditions, including geological features, water tables, and even hidden voids like undisclosed gravesites. Whether you're investigating underground utilities, assessing seismic hazards, or mapping archaeological sites, our geophysics team provides reliable and accurate results.
At Cook Costello, we offer a full range of geophysical surveys using non-invasive techniques to provide detailed insights into subsurface conditions. From seismic hazard assessments to utility mapping, our geophysics team delivers reliable and accurate results for various industries.
MASW - Multi-channel Analysis of Surface Waves
We use MASW to evaluate subsurface shear wave velocities for engineering applications.
SRT - Seismic Refraction Tomography
SRT helps us assess subsurface structures by measuring the refraction of seismic waves.
GPR - Ground Penetrating Radar
ERT - Electrical Resistivity Tomography
We use ERT to image subsurface conditions and identify water-bearing layers or contaminants.
Concrete Scanning
We provide precise concrete scanning to locate embedded objects like rebar and post-tension cables.
Other Geophysical Services
Site Period and Classification
We perform site period and classification to assess ground conditions and ensure structural stability for construction projects.
Void and Fracture Mapping
Using geophysical surveys, we map subsurface voids and fractures, helping identify hidden risks before construction begins.
Saline Intrusion and Aquifer Mapping
Our team conducts aquifer mapping to assess groundwater conditions, identifying saline intrusion risks and ensuring proper water management.
Landfill and Contaminated Land Mapping
We provide landfill mapping and identify contaminated land, supporting environmental assessments and cleanup efforts.
Seismic Hazard Assessment
Our seismic hazard assessments evaluate earthquake risks to help design structures that withstand seismic activity.
Locating Buried Objects
We use non-invasive ground investigation techniques to accurately locate buried objects, such as pipes and storage tanks.
Landslide Assessments
We use geophysical techniques to evaluate slope stability, providing critical data for landslide assessments and mitigation strategies.
Utility Mapping
We offer detailed utility mapping to accurately locate underground utilities, preventing costly disruptions during construction.
Subsurface Stratigraphy and Depth to Bedrock Mapping
Our geophysical surveys map subsurface stratigraphy, helping you understand soil layers and pinpoint the depth to bedrock.
Archaeological Feature Mapping
We offer archaeological feature mapping to identify and preserve buried historical sites during development projects.
Depth to Water Table
Our depth to water table surveys provide vital information for foundation design and water resource management.
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.
