Utility Services in Geelong

A Victoria-based company, Geoscan is a nationally accredited company that offers specialised services in underground utility, structural and geophysical investigation.

Utility Locating

Excavating without knowing the exact position of underground services can be risky. At Geoscan, we provide reliable utility location services in Geelong, using advanced underground pipe and cable locators to ensure every excavation is safe, accurate, and efficient.

Our services include detecting utilities such as:

Domestic water services
Fire services
Gas networks
Electrical networks (high and low voltage)
Telecommunications
Stormwater systems
Sewer and drainage conduits

When it comes to non-metallic services such as drainage pipes, sewer lines, or even empty conduits, Geoscan uses flexible tracer rods, Ground Penetrating Radar (GPR) and other state-of-the-art tools to deliver accurate results where traditional methods fall short.

With Geoscan, you can dig with confidence. Our approach reduces risk, prevents costly damage, and ensures projects across Geelong are completed with precision and efficiency.

Ground Penetrating Radar Investigation

Ground Penetrating Radar (GPR) is used to detect underground utilities, structures, and natural features that can impact your project. By identifying objects, voids, cracks, or changes beneath the surface, GPR helps reduce risks, protect assets, and keep works on track.

At Geoscan, our team has over 60 years of combined experience in subsurface investigations across the Geelong region. Using advanced radar systems and intelligent software, we deliver accurate results that give you clarity and confidence.

Our GPR investigations can identify:

Pipelines and utilities
Bedrock and geological features
Tree roots and voids
Underground storage tanks and hidden structures

Once anomalies are detected, we:

Mark them directly on the ground so clients can clearly understand their location.
Survey all anomalies for pre-design investigation work.
Provide a permanent record that supports safe excavation and long-term planning.

With Geoscan, you don’t just get detection — you get actionable data, mapped with precision, to support safer excavation, smarter planning, and better outcomes.

Surveying and Mapping

Clients often need a reliable record of underground service identification to support both structural and administrative project decisions. At Geoscan, we go beyond simply marking lines on the ground — we deliver comprehensive Utility Surveys that provide a clear, permanent picture of subsurface conditions.

Our surveys:

Record and map all identified services and GPR anomalies.
Highlight areas where services are not detected.
Show how utilities are connected and the networks they feed into.

All findings are carefully mapped to:

Match a local coordinate system or overlay onto existing surveys and architectural drawings.
Provide dimensions and offsets of pipes and cables relative to fixed features such as fences, building edges, and permanent structures.
Deliver clear visual references for both design teams and on-site crews.

For quick site clarity, we can also supply a Mud Map — a simplified drawing that shows service alignments and key offsets at a glance.

Our deliverables include:

AutoCAD (DWG) drawings.
PDF plans.
GIS-ready outputs for QGIS and ESRI.
Integration of MetroMap or high-resolution drone imagery for added context.

With Geoscan’s Utility Surveys, you gain more than just detection — you receive a complete, professional record that supports safe excavation, confident planning, and better project outcomes.

Underground services detection

Underground Cable Fault Detection

Underground services detection is a method that is most needed by the telecommunication, electricity and other branch of engineering companies. This method is exploited by these companies when they want to identify possible fault in the functional services meted out to their customers or for starting a new excavation.

Geoscan uses latest underground cable locators to help locate cable faults in Geelong exploiting underground cable fault finding method in Telstra cables; Communication/Data cables; Low voltage electricity cables, High voltage cables; Irrigation cable systems.

Metal Detection

Detecting metal involve broad spectrum of industries as well as purposes including but not limited to irrigation repair business; mining industry; security business at airport, government agencies; mining industry; construction industry, food industry; apparel industry etc…

The trained staff at Geoscan endeavors to detect both ferrous and non-ferrous metals in Geelong. The detection of ferrous metal is aimed at locating steel, cast iron and galvanized pipes. Our metal detectors can also locate buried utility valve box covers; buried irrigation valve box covers; buried stop taps; buried meter services; buried pit lid covers (metal or concrete covers); underground metallic storage tanks etc…
