Slab Scan
Slab Scan: The Complete Guide to Concrete Slab Scanning in Sydney
When it comes to construction, remedial work and fit-out projects, knowing what lies within a concrete slab is critical. A slab scan using Ground Penetrating Radar (GPR) is the safest and most effective way to identify reinforcement, services, and post-tension cables before any drilling, cutting, or coring takes place.
At ConcreteX, we specialise in concrete slab scanning in Sydney, helping builders, engineers, and trades avoid costly mistakes and keep projects safe and compliant.
What is a Slab Scan?
A slab scan is a non-destructive test that uses GPR technology to “look inside” a concrete slab. By sending high-frequency radar waves into the structure, we can detect changes in material and identify embedded objects.
A professional slab scan can reveal:
Post-tension (PT) cables
Steel reinforcement (rebar)
Electrical conduits (plastic and metallic)
Water and drainage pipes
Voids, cracks, or weak points
Foundations below the slab
This information is then mapped to guide safe drilling and cutting.
Why Concrete Slab Scanning Matters
Failing to carry out a slab scan can result in:
Damaging PT cables, which compromises structural integrity and creates major safety risks.
Cutting through electrical conduits or pipes, leading to costly repairs, shutdowns, and delays.
Non-compliance with safety standards and potential liability for rework.
By scanning first, you avoid these risks and gain confidence that your work can proceed without issue.
Slab Scan vs Concrete X-Ray
Many still refer to concrete x-ray when talking about locating objects in slabs. However, modern slab scanning with GPR has significant advantages:
Safer – no radiation hazards.
Faster – results are immediate.
More versatile – works with single-sided access to structures.
Cost-effective – no need to close off large work areas or length post-site processing.
In short, slab scanning provides the accuracy of x-ray with none of the downsides.
Who Needs a Slab Scan?
A slab scan in Sydney is essential for:
Builders and contractors preparing to drill or cut concrete.
Plumbers and electricians installing new services.
Engineers carrying out structural assessments.
Asset and facility managers planning upgrades in existing buildings.
If your project involves penetrating a slab, a scan should always come first.

Frequently Asked Questions About Slab Scanning
How much does a slab scan cost?
Costs vary depending on the slab size, access, and project complexity. Contact us for a tailored quote.
Is slab scanning safe?
Yes. GPR is completely safe, unlike x-ray, and poses no risk to workers or the public.
How long does it take?
Most scans can be carried out quickly on site, with results available the same day.
Do I need a report?
For some projects, on-site markings are enough. For others, a full PDF report provides clear documentation for compliance and records.
