Concrete Scanning
Scan slabs, walls and structural elements for detectable reinforcement, conduits and embedded features.
Know what's inside the slab.
Hitting post-tension cables, reinforcement or conduit can be costly and dangerous. A cut tendon or live conduit can stop a job, damage the structure and put people at risk.
Concrete scanning uses high-frequency GPR to identify detectable embedded features before you core, drill or cut, then marks clear zones directly on the surface.
Typical uses
- Coring and drilling
- Wall and slab saw cutting
- Electrical and hydraulic penetrations
- Fixings and anchors
- Reinforcement and conduit investigation
- Pre-demolition checks
Embedded conduit
Flag detectable conduits running through slabs and walls before saw cutting or coring.
Clear-zone marking
Mark safe areas and targets directly on the concrete, with photos of each location.
Mark it. Then cut it.

Example scenarios
Where this service fits.
Illustrative scenarios based on common site work. They are examples, not completed ASGPR projects.
100 mm cores through a suspended slab
The risk
Hydraulic risers need several 100 mm cores. The slab may contain post-tension cables, reinforcement and embedded conduit.
What ASGPR does
Scan each core location and a margin around it to identify detectable reinforcement, conduits and tendons.
What you get
Clear-zone markings at each core, notes on anything that could not be resolved, and photos of every marked location.

FAQs
Common questions.
Can you scan both sides of a slab?
Where access allows, scanning from the side you'll be working on is usually enough to mark detectable features. Some situations benefit from checking the soffit as well.
Will scanning tell me rebar size and cover?
Scanning can estimate spacing and approximate cover of detectable reinforcement. It is not a structural assessment; consult your engineer for structural decisions.
