Ferroscan Systems

It detects reinforcement like rebar, tendons, mesh and in some cases metallic conduits inside concrete. This, of course, helps avoid striking embedded objects when drilling or cutting.

It varies by model, but many systems can detect up to 100mm or more in depth. Devices like the Hilti PS1000 give layered rebar views at multiple depths.

Yes, it's completely non-invasive. It uses electromagnetic pulses to map what's inside concrete, so there’s no need for coring or cutting.

Most systems estimate rebar diameter based on signal strength and spacing, but exact sizing might need calibration or confirmation with physical measurement.

Ferroscans are designed for shallow concrete scanning and reinforcement mapping, while GPR can go deeper and detect a wider range of subsurface materials.
