In present era, there are so many buildings which collapse fully or partially due to lake of maintenance, improper construction method and material or even due to earthquake. They need repairing to make them safe. Repair are always neglected or delayed by many people in most of building owing to lack of awareness and financial ability and so it leads to major hazards. Hence, it is needed proper repair and reconstruction application. In this project we have more focus on repairing on building which have required maintenance, because most of problem occurs after certain life of building. In addition, we have also focus on repairing of that sort of structure which have more than of their certain life and which has affected by some disaster like earthquake, flood, etc. At last, we will suggest some useful innovative materials and its application, how to apply on damage part, which would ultimately improve the strength of the structure.
