Preventive Inspections                                                               


There are two basic motivations for the early diagnosis of possible problems in reinforced concrete structures. There is the financial motivation given by the need to protect the large investments made during the construction.  But there is also a social motivation and responsibility to protect the life and well being of the occupants of buildings and the users of facilities such as bridges and highways, especially in cases where there are indications of possible structural problems.

We show below, examples of disasters that could have been avoided through the use of appropriate inspection techniques.  The non destructive inspections, and in particular, the gamma ray tomography provide technical, practical and economical advantages described on the pages on Services and Technology.
