When Metal Detection Is the Right Tool
Some jobs don’t need ground penetrating radar or cable locating — they need a targeted, systematic sweep for buried or surface-level metal objects. Metal detection is the appropriate method when the task is to locate, count, or recover metallic objects across a site, structure, or area: whether that’s cleaning up fasteners and debris after construction, recovering buried irrigation or service infrastructure, confirming clearance of a secure facility after a build, or locating buried valve boxes, stop taps, and meter covers that have been lost underground.
Geoscan’s metal detection service covers both ferrous metals (steel, cast iron, galvanised pipe) and non-ferrous metals (brass fittings, copper cable, aluminium infrastructure) — giving you a complete picture of what’s in the ground before excavation, handover, or commissioning.
What We’re Called In For
Metal detection is required across a range of commercial, construction, and infrastructure scenarios. Common applications Geoscan supports across Victoria:
Post-Construction Site Clearance
Systematic sweep of construction sites after completion
Locating and recovering fasteners, reinforcing offcuts, fixings, and metallic debris
Area-by-area clearance with documented results
Suitable for handover, DA compliance, and insurance requirements
Correctional Facilities & Secure Building Sweeps
Post-construction or post-renovation metal sweeps in correctional facilities, remand centres, and secure buildings
Confirms no metallic contraband, tools, or fixings have been left accessible
Written sweep certification and compliance records provided
Discreet, professional service for sensitive environments
Buried Infrastructure Recovery
Locating buried valve boxes, stop taps, meter service boxes, and pit covers
Recovering service infrastructure that has been lost through resurfacing, fill, or vegetation
Supporting maintenance programmes and asset management records
Marking in the field for excavation or service access
Underground Storage Tank Location & Perimeter Marking
Detecting and marking buried fuel tanks, chemical storage vessels, and metallic containment structures
Used for environmental due diligence, property transactions, and pre-development investigation
Perimeter marking supports targeted excavation
Can be combined with GPR for non-metallic features
Irrigation System Recovery
Locating buried irrigation valve boxes, solenoids, and metallic fittings
Recovering irrigation infrastructure after fill, levelling, or vegetation growth
Suitable for farms, golf courses, parks, and commercial landscaping
Marking positions for maintenance and system reinstatement
General Buried Metal & Site Investigation
Locating buried metallic objects across any site type
Underground metallic storage tanks, anchoring structures, and buried assets
Historical infrastructure investigation and pre-demolition surveys
Can be combined with GPR and utility locating for a complete subsurface picture
What Geoscan’s Metal Detection Can Find
Geoscan’s metal detection equipment is capable of detecting both ferrous and non-ferrous metallic objects — in the ground, within fill or aggregate, and in some cases within concrete or masonry structures. Detectable objects include:
Reinforcing steel (rebar) and structural steelwork
Cast iron and galvanised pipes
Copper cable and wiring
Brass fittings, valves, and connectors
Aluminium conduit and infrastructure
Buried valve boxes, meter boxes, and pit covers
Underground metallic storage tanks and vessels
Irrigation solenoids and metallic fittings
Fasteners, bolts, wire, and construction debris
Buried anchors, stakes, and structural elements
How Geoscan’s Metal Detection Service Works
Contact Us & Define the Scope
Tell us the site location, the type of area to be swept (construction site, facility floor, paddock, car park), and what you’re looking for or need to confirm is clear. We’ll advise on the approach, provide a quote, and confirm mobilisation.
On-Site Metal Detection
Geoscan’s technician arrives on site and conducts a systematic sweep of the nominated area using professional-grade metal detection equipment. The sweep follows a defined pattern to ensure full coverage. All detections are flagged in the field and logged — including object type (where identifiable), approximate depth, and location.
Clearance Confirmation or Report
For most site clearance and facility sweep jobs, the primary deliverable is an on-site sweep confirmation — a clear record that the nominated area has been swept and any detections have been identified or recovered. Where written certification is required (particularly for correctional facilities and secure building handovers), a formal sweep certificate and compliance record is provided.

Frequently Asked Questions
What types of metal can you detect?
Geoscan’s equipment detects both ferrous metals (steel, cast iron, galvanised iron) and non-ferrous metals (copper, brass, aluminium). This covers the majority of buried infrastructure, construction debris, and service fittings typically encountered on commercial, construction, and agricultural sites.
How deep can metal detection reach?
Detection depth depends on the size of the object, soil composition, moisture content, and the presence of competing metallic material in the area. Geoscan will advise on expected detection capability for your specific site and application at the quoting stage.
Do you provide a written report or compliance certificate?
Yes. For correctional facilities, secure building handovers, and other jobs where compliance documentation is required, Geoscan provides a formal sweep certificate confirming the nominated area has been swept, detections have been identified, and the area has been cleared to the agreed standard. For standard clearance jobs, a site sweep record is provided as a matter of course.
Can metal detection be combined with utility locating or concrete scanning?
Yes — and this is often the most efficient approach. Many sites require both utility locating and a metal sweep, or a concrete scan alongside a general site clearance. Geoscan can combine services in a single mobilisation, reducing cost and site disruption.
Do you carry out sweeps in correctional facilities and secure buildings?
Yes. Geoscan provides post-construction and post-renovation metal sweeps in correctional facilities, remand centres, and other secure buildings across Victoria. Our team is experienced in working within sensitive environments and understands the compliance and documentation requirements specific to these engagements.
What areas do you service for metal detection?
Geoscan is based in Geelong and services the Surf Coast, Bellarine Peninsula, Melbourne metropolitan area, and broader regional Victoria. Contact us to confirm mobilisation availability for your location.
