Abstract: 
Structures are assemblies of load carrying members capable of safely transferring the superimposed loads to the foundations. But after it is completed, it is inevitable that the process of deterioting starts on account of natural forces like rain, sun etc. Structural deficiency is also due to defect in construction, use of inferior material, poor workmanship and negligence in quality control and supervision, leakages from roofs, walls and other parts of the structure and corrosion in the reinforcement are the evidences. A correct diagnosis of the defects in structure and proper selection of materials for repairs is very essential. The diagnosis should establish the cause, nature and extents of damage and weakness or deterioration caused in the structure and assess the serviceability of the structure. Now days there are many methods and techniques available and Non-Destructive Evaluation (NDE) techniques are one of the methods to evaluate any damage in structure. Non destructive techniques can be used effectively for investigation and evaluating the actual conditions of the structures. These techniques are relatively quick, easy to use and cheap and give a general indication on the property of hardened concrete. The choice of particular NDT depends upon the property of concrete to be observed such as strength, corrosion, crack monitoring etc. In this paper, the NDT tests conducted on different case studies are discussed. The NDT tests conducted on Storage tank or silo (cylindrical shape) of a Cement Factory of height 81 meters and multistoried residential apartment. In these cases, the problems are different for each structure.NDT tests has been conducted to check the performance after rehabilitation done to these structures. From NDT experimentation it was found that the results are satisfactory.
