Strengthening of reinforced concrete structures is given top priority in construction sector across the world. Due to ageing of existing structures and change of expected load patterns, the stability of structure may be reduced. In this case, Fibre Reinforced Polymer (FRP) materials have been recognized as vital constituents to solve stability issues of the modern concrete structures. The FRP material has improved structural performance in terms of stability, stiffness, strength and durability. Fibre-Reinforced Polymers wrapping is one of the widely used technique to restore the strength of a concrete structures.This review paper focuses on various wrapping techniques of fiber-reinforced polymer sheets for external strengthening of reinforced concrete structures such as reinforced circular columns, square beams, columns and column-beam joints. The purpose of this study is to present a constructive critical review of the techniques for FRP retrofit concrete structures.
