Concrete Scanning with GPR

Concrete scanning with Ground Penetrating Radar (GPR) uses radar pulses to detect objects embedded within concrete structures. It helps locate rebar, post-tension cables, pipes, conduits, and voids—ensuring safe cutting or drilling without damaging hidden elements.

GPR uses radio waves and requires access to only one side of the structure, making it faster, safer, and more versatile than X-ray. X-ray imaging, while detailed, involves radiation exposure, requires access to both sides, and often comes with higher costs and safety protocols.

For most construction and renovation projects, GPR is the preferred choice due to its speed, safety, and real-time data output. X-ray may be better suited for extremely dense materials or high-precision applications in medical or forensic environments.

GPR can typically scan up to 18 inches deep into concrete, depending on the material’s density, moisture content, and the amount of reinforcement. Lower-frequency antennas can reach greater depths but with lower resolution.

GPR scanning can identify:

Rebar and post-tension cables

Conduits and embedded pipes

Voids or air pockets

Slab thickness and layer composition

Hidden utilities and anomalies

Locating utilities before cutting, drilling, or excavating prevents accidental damage to electrical lines, water pipes, gas mains, and communication cables—reducing safety risks, costly repairs, project delays, and liability.

Utility locating is essential for:

• General contractors
• Electricians and plumbers
• Facility managers
• Excavation crews

Homeowners planning renovations

These services ensure a safe, code-compliant start to any construction activity—especially in urban or densely developed areas.

Yes. GPR is effective on vertical surfaces such as walls, columns, and ceilings, allowing safe detection of rebar, conduits, and other embedded elements before drilling or coring.

Yes. GPR is completely non-destructive and emits no harmful radiation. It is safe for use on active construction sites as well as in sensitive environments like schools, hospitals, and residential properties.
