Concrete Scanning vs X-Ray: What’s the Difference?
When it comes to investigating what’s inside a concrete slab, two common methods are used: Ground Penetrating Radar (GPR) scanning and X-Ray imaging. Both aim to locate reinforcement, post-tension cables, conduits, and other embedded objects — but the way they work, and where they’re best applied, are quite different.
How Concrete X-Ray Works
Concrete X-Ray uses radiation to create an image of what’s inside the slab. It produces highly detailed visuals but comes with some drawbacks:
Safety concerns – Radiation requires site evacuations and strict controls.
Access to both sides – To capture an image, the technician needs access to both sides of the slab or wall.
Time and cost – Set-up, evacuation, and processing make it slower and more expensive than other methods.
How GPR Concrete Scanning Works
GPR uses radio waves to detect changes in material density inside the slab. At ConcreteX, we use advanced GPR equipment to quickly scan and interpret subsurface conditions. Key advantages include:
Safe and non-invasive – No radiation, no evacuations, completely safe for active sites.
Single-side access – We only need access to one side of the slab.
Speed – Fast mobilisation and scanning, with same-day or next-day reporting.
Cost-effective – Lower setup costs compared to X-Ray.
Which Method Should You Choose?
While X-Ray can provide very detailed images in certain specialised situations, GPR scanning is the preferred method for most projects. It’s faster, safer, and more practical on active construction sites. That’s why builders, engineers, and facility managers across Sydney rely on GPR for everyday drilling, coring, and investigation needs.
Why ConcreteX?
At ConcreteX, we combine advanced scanning technology with engineering insight to deliver accurate results quickly. Our team provides clear, detailed reports so you can move forward with confidence, knowing exactly what lies beneath the surface.
