Non-Destructive Subsurface Inspection

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I am interested to find out if there is an inexpensive solution for finding 
subsurface voids (sinkholes) via ultrasound etc.  If so can it be used 
directly on the surface of the soil and also through a concrete slab.  If 
anyone has any experience with this type of NDI please let me know.
