Ground Penetrating Radar?
Ground Penetrating Radar?
(OP)
I am trying to perform a non destructive testing of a building shear wall which is about 20" thick. I was thinking of using GPR (ground penetrating radar) to do the probe. Due to congestion of reinforcing in the wall, I am giving second thought to this GPR, as it will be unable to descern closely spaced reinforcing and reveal the delamination behind them!
Can you guys point me to any other NDT methods that can reveal any structural imperfection in this wall under these circumstances?
Thanks in advance.

Keep in mind, thermography won't show the reinforcement only the delaminations but not the depth, and the surface needs to be exposed to sunlight for a few hours. There's a firm in Milwaukee that I've dealt with in the past.
You can use an x-ray but I wouldn't recommend it. There are too many safety concerns to deal with.

IE would work in the hands of a seasoned NDE engineer, as reflections from a backside delam would be indicated as a thinner section of wall. Areas where the wall is say 15 in. would likely indicate a delam. As always with any NDE methodology, confirmational testing (coring, drilling, etc.) is recommended.
