How it works
We combine millimetre-accurate 3D tracking with ground penetrating radar, then turn the raw signals into rebar geometry you can act on straight away.
The process
GPR and lidar in a single handheld unit
01
Roll the tracked unit across the surface. Ground penetrating radar, lidar and camera capture the structure together, at up to 500 m² per hour. The handheld scanner fuses ground-penetrating radar with LiDAR-based positioning. Every radar trace is registered to a millimetre-accurate point cloud as you sweep, so every reading knows where it came from.
Rebar detected and positioned while you scan
02
The signals are fused and interpreted on board. No upload, no waiting for an office to process the raw data.
Diameter, cover and spacing, in the field
03
Rebar position, cover and diameter appear as a 3D model with millimetre accuracy while you are still on site.

04
Everything lands in one place in the cloud, and you decide who gets in. The structural engineer, the client and the contractor each get their own access and see exactly what you see. Nothing emailed around, no two versions in circulation. If someone needs the data inside their own software, it comes out in the formats their tools already read.
Under the hood
Three pieces of physics and maths make a non-destructive survey trustworthy.
Instead of reading peaks in a radar trace, we model the entire waveform and solve for the material properties that could have produced it. The method comes from seismic imaging in oil and gas, where it is used to reconstruct kilometres of rock, we apply it to centimetres of concrete.
The radar emits short electromagnetic pulses into the concrete. Every change in material (a steel bar, a void, a moisture front) reflects part of that pulse back. Travel time and shape of the reflection tell us depth and size, and millimetre-accurate 3D tracking ties every single trace to an exact position on the structure.
Models trained on field data from more than 70 projects separate rebar from noise, follow each bar through the volume and estimate diameter and cover automatically. The interpretation is consistent between operators, and the output is a structural model rather than an image someone has to read.
