Concrete buildings are facing some serious issues around the world. There are a few reasons for this, natural disasters such as earthquakes, lack of knowledge about important building codes, and poor supervision during construction. Because of these problems, many buildings are weaker than they should be. If these structures are under too much weight, they can bend and corrode, which means immediate repairs are needed. To tackle these problems with reinforced concrete, repair and strengthening methods have become really important in construction today. Even new buildings sometimes end up needing fixes because of design mistakes or problems during building. Structures that have been damaged by unexpected events like fires or earthquakes need special techniques to make them strong again. Fixing up buildings helps protect them from earthquakes and reduces the risk of damage. It's all about boosting a building's strength to meet safety standards. Many studies have looked into effective ways to reinforce them. This paper will take a brief look at some new and cost-effective methods for repairing damaged buildings.
