The cost of our tomographic services is comparable with other methods currently in use for the inspection and diagnosis of reinforced concrete structures. The advantages we offer are however very clear.


The destructive inspection methods are obviously inconvenient for finished buildings, especially if they are inhabited.  These methods involve the removal of facings, the chipping of walls, the use of cooling water for the cutting tools, and, of course at the end, the additional time and expense for performing the repairs.


The chipping and drilling of holes in structures to inspect rebars is normally limited to areas and depths which are small compared with the volume that can be inspected by using a gammagraphy (the size of a gammagraphy is 14" x 17”).


The other non-destructive methods used in the construction industry, such as radar, sonics waves, IR or microwaves, only detect the presence of rebars located close to the surface, and only in a qualitative way. With these methods it is usually impossible to measure diameters and positions of the rebars with the required precision.  

RCT causes a minimum of disturbance as can be seen in this example of the study of a concrete wall in an inhabited apartment.

Detailed and precise non-destructive inspection and diagnosis, particularly for structures with high density of reinforcing steel, such as large beams with various layers of steel, for “seeing” corrosion and for assessing honeycombing, requires the gammagraphic techniques we have developed.  Also the volume easily accessible with these techniques are much larger that normally accessible with destructive methods.
