Concrete building deterioration is a worldwide problem in the present environment. This is because some of the causes include natural hazards such as earthquakes, lack of adherence to some very important and necessary codal rules in construction, poor supervision, and many others. Hence, the structures are weak. Deformations and corrosion are severe when loads are applied on the structures, and they need to be addressed immediately. It is therefore imperative to mention that repair, retrofit, and strengthen are some of the usual processes that are currently employed in the construction industry in order to address all these effects on reinforced concrete structures. Even newly constructed buildings can require repair or reinforcement to address design flaws or construction deficiencies. Strengthening involves specialized techniques to enhance the capacity and restore structural elements damaged by fire, earthquakes, foundation settlement, impacts, or overloading. Retrofitting provides an effective method to ensure that existing structures are better prepared to withstand future earthquakes or other natural hazards. Retrofitting reduces the chances of damage to a structure in the event of seismic activity in the near future. It is an effort to bring a structure to comply with the present seismic design standards. In the last few years, a lot of effort has been put into the development of different types of strengthening and rehabilitation methods to enhance the seismic performance of structures. The aim of this paper is to present a number of innovative and cost-effective local retrofitting techniques that can be used to improve the strength of damaged structures.
