The Reinforced Concrete Tomography (RCT) method allows detailed visualization of the interior of structural elements and: 

    Determination of positions and dimensions of rebars and braces,

    Inspection of sheaths and cables in post-tensioned girders (defective grouting and corrosion),

    Detection of corrosion in steel bars,

    Identification of piping and obstructions,

    Detection of honeycombing,

    Location of optimum spots to drill holes without damage to the reinforcement. 

RCT is the only non-destructive technique capable of providing reinforcement information with the accuracy required to establish the ability of a structure to support a given load. In the past, to see the reinforcement in a concrete structure it was necessary to use hammers, chisels and drills to remove substantial amounts of material. 

Today, through a computed tomography the location, size and condition of the rebars can be known without causing any damage.

The fact that this method is non-destructive saves time, materials and manpower. 

The cost of repairing the damage is eliminated. In the case of inhabited buildings the advantages of cleanliness, speed and noise free operation, become even more important. Load tests or destructive inspections are risky for balconies and projections, where the location and condition of the reinforcements are particularly important. 

In these cases the Reinforced Concrete Tomography provides the only available solution.

THASA has successfully completed non-destructive testing of over 1000 public and private structures such as bridges, buildings, piers, etc. (see CUSTOMERS).
