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.
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.
