the best method for detecting and localize the rebars

Hi,

To confirm the appropriate overlapping of the rebars at the construction joint, I am looking for the method that can tell me if there is rebar or not at the joint.

if anybody could tell me the potential methods that may answer my question, I will definitely apprepriate.

Thanks!

With the information you have provided, I assume you are talking about reabars in a cement floor? If you have access to both side of the slab, I suggest doing radiography using Co 60. I believe the equivalence factor for cement is 10:1 compare to steel. This way you will also have an exact picture of the way it is inside. There maybe other ways that I don't know. My experience in that field is very limited. I hope this will help you.
