Rebar Mapping
Full reinforcement mapping with depth, spacing, and layout — delivered in CAD-ready formats.
Rebar mapping UK from Corvus is part of our gpr concrete scanning service. Rebar mapping with GPR gives a top-and-bottom-layer view of reinforcement at survey-grade accuracy. Output goes into your CAD environment as a DXF or DWG plan with depths annotated for each bar.
Built around the question being asked.
A surveyor passes a high-frequency antenna over the surface in a grid pattern. The antenna emits short electromagnetic pulses. Anything with a different dielectric to the host concrete — steel, water, voids, plastic conduit — reflects part of the signal back. Software builds a depth-indicative map of detectable reflectors and likely target positions within the scanned area. Targets are then marked up on the slab itself and supplied as a digital deliverable.
For rebar mapping specifically, the brief drives the choice of frequency, density, and reporting style. We quote a method that fits your access window, your accuracy requirement, and the downstream use of the data.
What you get
- On-slab marker plan in survey paint or chalk
- Annotated PDF report with depths and locations
- Digital DXF / DWG plan compatible with your CAD software
- Photographs of marked-up areas
- Surveyor sign-off and method statement
Calibrated. Qualified. Defensible.
- 01
Calibrated kit checked at the start of every session, with the calibration record supplied in the project pack.
- 02
Surveyors qualified for the method, signed off on the report by the person who did the work — no anonymous deliverables.
- 03
Reporting written for the engineer or contractor who has to act on it, not for the file.
- 04
Same-day quotations and a date in the diary. UK-wide coverage. No minimums on small jobs.
