Pre-Core & Pre-Cut Concrete Scanning
Before any core, sawcut, trench or anchor goes into a slab, you need to know what is inside it. Pre-core and pre-cut concrete scanning uses GPR to locate rebar, post-tension cables, electrical conduit and embedded pipe at each penetration — so your crew cuts with confidence instead of guessing and hoping.
Scan before you cut — every time
Coring or sawcutting blind risks striking rebar (delays and weakened structure), post-tension cables (a life-safety failure), live conduit (electrocution) or pipe (flooding). A quick GPR scan at each location turns a gamble into a controlled, documented operation.
What we locate at each penetration
We mark every embedded hazard around the planned cut or core:
Reinforcing steel
Rebar mats and their cover depth, so you avoid or plan around them.
Post-tension cables
The critical no-cut hazard in PT slabs.
Conduit & embedded pipe
Electrical conduit and in-slab plumbing that must not be struck.
Same-visit marking on site
Results are real-time: we scan, interpret and mark safe cut/core zones on the slab on the spot, with depth — so your trades proceed the same visit.
Detection methods we use
GPR scan at each location
Maps embedded elements directly around the planned penetration.
Safe-zone marking
Clear cut/core points marked on the surface with depth.
Multi-penetration layouts
Efficient scanning of many core/cut locations across a floor.
Where this applies
- Mechanical, electrical & plumbing penetrations
- Slab sawcutting for repairs or drainage
- Commercial tenant-improvement coring
- Industrial floor and equipment-base penetrations
What you receive
- Marked safe cut/core points at every location
- Embedded hazards (rebar, PT, conduit, pipe) flagged
- Depth guidance for the operator
- Scan record for the project file

Frequently asked questions
Why scan before coring or cutting?
To avoid striking rebar, post-tension cables, live conduit or pipe — each of which causes delay, cost, structural damage or injury. A scan makes the penetration safe and documented.
Can you mark multiple core locations in one visit?
Yes. We scan and mark as many penetration points as your layout requires in a single mobilisation.
Do you provide depth so we know how far to core?
Yes. We mark safe zones and provide depth estimates for the embedded elements so coring depth is planned safely.
Is GPR safe to use in an occupied building?
Yes. GPR is non-ionising with no exclusion zone, so we scan in occupied spaces during business hours.
