Detection of defects on Concrete using Lamb waves.

Please tell me the possiblity to success this inspection.

I am using:
Frequency 50kHz
Size of specimen 31cm
Defect types: honeycombed, water filled & air defect inside concrete about middle of the specimen.

Problem:

not consistence
Too sensitive.
Large thickness.
Higher mode due to large thickness.

Suggestion:

I need some suggestion for my master & Ph.d thesis doing this research.
please feel free to comment and give me some hope and advise for my study at university.

nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
