Investigating and Protecting Structures
HCS are concrete scanning specialists. We provide our clients with fast and precise insights into the structure, strength and composition of their concrete structures. We give structural engineers, building contractors, forensic experts and concrete specialists the essential information they require and service multi-national companies, engineering and construction specialist, local and state government bodies as well as residential and small business clients.
Concrete scanning is a cost-effective solution for your construction or engineering project. We are a trusted service provider using the latest technology in the industry. Utilizing the latest GPR (Ground penetrating radar)/ concrete scanning technology to reduce the risk associated with trench cutting and core drilling. We carry the best technology available, including the Proceq GP8000, to deliver the most accurate results on every project.
Whether we’re assessing the strength of a slab to accommodate a great load at a warehouse or reporting on the impact of holes drilled for cathodic protection, our concrete scanning specialists provide the critical information people need to make important decisions.
Much of the information produced by our technicians is acquired in real time, we are often able to provide on the spot information about where services, reinforcement and defects lie. Images and interpretations of them are provided in a timely manner and the process of acquiring the information is safe, non-destructive and can be done without significantly disrupting the space being scanned.
Concrete Scanning Applications
- Detection of frequency and position of ligatures in structural beams.
- Column analysis for ligature position and depth.
- Non-Destructive testing for construction failure analysis.
- Reinforcing steel positioning prior to drilling/coring.
- Bridge Deck Analysis
- Construction quality assurance
Concrete Scanning Experience
HCS have significant concrete scanning experience in various facets of infrastructure.
Our concrete scanning specialists have been engaged for concrete scanning requirements on facade investigations, structural integrity checks and core hole clearances.

Areas We Service in Melbourne
HCS technicians run concrete scanning projects across metro Melbourne, from CBD high-rise builds to growth-corridor developments, wherever a slab, beam, column or bridge deck needs to be understood before it’s cut, cored or drilled.
Inner Melbourne and CBD: Melbourne CBD, Docklands, Southbank, Fitzroy, Carlton, Richmond, South Yarra, high-density sites where structures are often decades old, plans are incomplete, and multiple trades are working around a single scan window.
Growth corridors: Tarneit, Truganina, Point Cook, Craigieburn, Epping, Pakenham, Cranbourne, new-build commercial and residential projects where slab specifications are known but as-poured reinforcement still needs verification before penetration works.
If your site isn’t listed here, get in touch. Melbourne coverage extends across the metro area, and Newcastle and Brisbane are serviced from HCS’s other offices.
Working on a Melbourne site? See our Concrete Scanning Melbourne page for local coverage details, or our Structural Investigation Melbourne page if you need a full structural assessment.
What Affects Concrete Scanning Accuracy and Depth
GPR performance inside concrete isn’t fixed – it depends on the structure being scanned. Dense, low-moisture concrete with standard aggregate gives the clearest reads; heavily reinforced sections, high moisture content, or non-standard aggregate all reduce how far a signal reliably penetrates. Closely spaced reinforcement can also mask what sits behind it, which is why HCS scans critical elements from multiple angles rather than relying on a single pass. If a scan reaches the practical limit of what GPR can confirm on a given element, that’s flagged as part of the report – not glossed over as an unqualified all-clear.
Frequently Asked Questions
What is concrete scanning and why is it needed before cutting or coring?
Concrete scanning uses ground penetrating radar (GPR) to see inside a concrete slab, beam or column before any cutting, coring or drilling begins. It identifies reinforcing steel, post-tension cables, conduits and other embedded services so you can avoid cutting into critical infrastructure, reduce the risk of structural damage, and keep the job safe.
What can concrete scanning detect?
HCS's GPR concrete scanning can identify the position and depth of reinforcing steel and ligatures, post-tension cables, conduits and voids, and other embedded services within a concrete structure — giving a clear picture of what's inside before you cut, core or drill.
Is concrete scanning safe and non-destructive?
Yes. Concrete scanning is a non-destructive, non-invasive process — no drilling or damage to the structure is required to gather the data. Scanning can typically be carried out without significantly disrupting the space being investigated.
What areas do you service?
HCS provides concrete scanning across Melbourne and Victoria, with additional offices in Newcastle, NSW and Brisbane, QLD.
Are your concrete scanning technicians accredited?
Yes — HCS's concrete scanning technicians are accredited CERTLOC, helping minimise the risk of service strikes on and around the structures we scan.
What applications is concrete scanning used for?
HCS's concrete scanning supports a wide range of applications, including detecting the frequency and position of ligatures in structural beams, column analysis, non-destructive testing for construction failure analysis, reinforcing steel positioning prior to drilling or coring, bridge deck analysis, and construction quality assurance.
What do I receive after a concrete scan?
Much of the information is captured and interpreted in real time, so our technicians can often provide on-the-spot findings about the location of services, reinforcement and defects. You'll also receive images and interpretations of the scan results in a timely manner to support your project decisions.
How do I book a concrete scan or get a quote?
Call 1300 859 027 or submit an enquiry through the form below, and the team will confirm scope and scheduling for your site.
Is this the same as slab scanning?
Yes, 'slab scanning' and 'concrete x-ray' are both terms people use for the same core service: using GPR to see what's inside a concrete slab, beam or column before you cut or drill into it. HCS uses 'concrete scanning' as the umbrella term because GPR isn't the only technique involved in a full investigation, but if you've been searching for slab scanning or concrete x-ray in Melbourne, this is the right service.
Does Melbourne's concrete construction affect how a scan is read?
Slab composition varies more than people expect: aggregate type, mesh vs. bar reinforcement, post-tensioning, and moisture content in the concrete itself all affect how clearly a GPR signal reads back. This is a different variable to ground conditions, which matter for underground service locating rather than concrete scanning, but it's exactly why HCS technicians calibrate scan settings to the structure in front of them rather than running a single default setting across every job.
How long does a concrete scan take?
Most single-element scans (a wall, a column, a section of slab) take under an hour on site. Larger areas or multiple elements take longer – HCS confirms scope and an estimated timeframe with you before the job starts.
How much does concrete scanning cost?
Cost depends on the size and number of elements being scanned, site access, and how quickly you need results. Call 1300 859 027 or submit an enquiry and the team will scope a quote for your project.
How deep can concrete scanning detect reinforcement or services?
Effective depth depends on the concrete itself – density, moisture, aggregate and reinforcement spacing all affect it. See ‘What Affects Concrete Scanning Accuracy and Depth’ above for detail; HCS flags it clearly if a scan reaches the practical limit of what GPR can reliably confirm.
