Buildings and other structures have a certain useful life, which depends on the specifications adopted. The large numbers of monuments, which are cherished heritage structures have stood well over a period of time. But some of these have shown signs of distress due to age, aggressive natural environment/industrial pollution etc. Further, distress gets aggravated due to overloading and misuse of buildings. A few buildings have also failed due to faulty design or construction. The various causes of structural failure and the principles of rehabilitation of structures are discussed. In the proposed approach we used Damage Detection and It's Repairs and Rehabilitation Techniques in RCC Structures Using NDT 1) Half-cell potential meter 2) Resistivity meter For Corrosion Mapping 3. Ultrasonic Pulse Velocity 4. Rebound Hammer. In the structures, the cracks are generated due to different causes e.g. in some cases cracks are caused after the structure has been completed for a few years which results in shortening of life and strength of structure. The purpose of this paper is damage detection and its repairs and rehabilitation techniques in RCC structures using NDT. For corrosion mapping to justify the latest techniques, advanced materials and various requirements of repairing work to obstruct the deterioration which is necessary and economical than to reconstruct the building.
