Non-Destructive slab scanning

Rebar Scanner & Concrete GPR Scanning

Locate reinforcement structures, conduits, and post-tension cables inside concrete slabs, columns, and walls. Prevent utility strikes and preserve structural integrity during renovations and coring projects.

Map Rebar & Conduits with Concrete GPR

Protect your site workers and preserve structural integrity. Our technicians use high-frequency concrete radar (GPR) sensors to scan concrete floors, walls, and columns, locating embedded elements with high precision before any drilling, coring, or cutting begins.

Unlike electromagnetic locating which only detects current-carrying lines, high-frequency GPR waves bounce off metal rebars, post-tension strands, voids, and plastic conduits. This provides a complete 3D picture of what is inside the slab down to 600mm.

Locate Post-Tension (PT) Cables & Tension Tendons

Cutting a post-tension (PT) cable can cause immediate structural collapse or severe injury due to the high energy released. Our scanning methods isolate tension tendons, allowing structural engineers to sign off on core placements with absolute safety.

01

Prevent electrical shock: Pinpoint plastic and metallic conduits containing live power lines before cutting slabs.

02

Avoid structural damage: Prevent the severing of structural steel bars to maintain concrete slab integrity.

03

Coring sign-off: Provide structural engineers with depth charts and coordinates for core drilling clearance.

Frequently Asked Questions

Get answers to common inquiries about concrete GPR scanning and rebar locating.

Concrete GPR scanning can typically penetrate up to 600mm depending on concrete age, moisture, and density, which is more than sufficient for most slab-on-grade and suspended slab configurations.
Drilling or coring through post-tension (PT) cables or structural reinforcing steel can cause catastrophic structural failure, and hitting embedded conduits can cause electrocution or gas leaks. Scanning ensures safe paths for slab penetrations.
Yes, unlike covermeters which only detect magnetic metals, Ground Penetrating Radar (GPR) detects both metallic and non-metallic objects (such as PVC conduit, plastic pipes, and voids) by sensing dielectric differences.
We provide immediate on-site marking directly on the concrete surface, followed by a comprehensive PDF report containing scan locations, depth profiles, and 3D reconstruction layouts if requested.
