How to detect/identify reinforcement bars inside the hardened concrete?

How to detect/identify reinforcement bars inside the hardened concrete, such as footings and columns without destructing the built concrete?

Where am I?

Hello,

A rebar locator can definitely identify the presence of a Steel reinforcement rebar as well as its orientation inside the concrete surface.

A rebar locator itself indicates its meaning.

Actually, we can use a pulse indicator method which is totally based on electromagnetic pulse induction Technology to detect rebars.

Thank you.
