Metatek provides geophysical survey services to support accurate and efficient site investigation across construction, engineering, environmental, and resource projects.
A geophysical survey is used to gather information about subsurface conditions without excavation. It helps identify what lies beneath the ground at an early stage, supporting better-informed decisions before intrusive investigation or construction begins.
This article explains what geophysical surveys are used for and how they are applied across different industries.

Geophysical exploration uses a range of survey techniques to investigate subsurface conditions by measuring the physical properties of the ground. Methods may include seismic, magnetic, electromagnetic, or ground
penetrating radar surveys, depending on project requirements.
The information collected helps identify variations below the surface, providing valuable insight into geological conditions across a whole site rather than at individual sample points.
Geophysical surveys are used across many different industries to explore what lies beneath the surface of the Earth.
In construction and civil engineering, geophysical surveys are used to assess ground conditions before development work begins.
They help identify variations in subsurface conditions that may influence foundation design and overall site suitability and are commonly used at the feasibility stage to inform how a site is developed.
Geophysical surveys are also widely used in infrastructure projects such as roads, rail, and utilities.
They help map subsurface constraints along proposed routes, identifying potential obstructions, changes in ground conditions, or areas of weakness that may affect design or construction.
One of the most common uses of geophysical surveys in this sector is locating ground hazards before work begins.
They are used to detect potential hazards such as voids, buried services, or unstable ground conditions, so that these can be located and mapped ahead of construction.
In mining and resource exploration, geophysical surveys are used to identify subsurface structures that may indicate the presence of mineral deposits.
This allows exploration teams to focus on areas with higher potential, improving the efficiency of early-stage investigation.
Geophysical methods are also used to understand geological structures beneath the surface.
They provide insight into rock formations, faults, and structural variations during the initial stages of resource assessment.
By providing early subsurface information, geophysical surveys allow high-potential areas to be prioritised before wider investigation work begins.
Geophysical surveys are commonly used in environmental investigations to identify subsurface anomalies associated with contamination or historic landfill sites.
This helps guide remediation planning and supports more targeted environmental assessment work.
Geophysical surveys support more sustainable investigation practices by reducing the need for intrusive groundworks.
Geophysical surveys play an important role in modern site investigation by providing early insight into subsurface conditions without the need for excavation.
Across construction, infrastructure, mining, and environmental projects, they are used to map ground conditions, locate hazards, and target further investigation where it is most needed.
Their ability to reduce cost, risk, and environmental impact makes them a valuable tool in delivering more informed and effective project outcomes.
