Hi, Following are some process to identify the defects and done inspection of Steel bars in reinforcement concrete

  1. Eddy current Technique,
  2. Single frequency method,

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.
