Beams and Columns Strengthening is a structural rehabilitation technique aimed at enhancing the load-bearing capacity, stiffness, and durability of existing reinforced concrete members. This process involves the use of high-performance materials such as fiber-reinforced polymers (FRP), micro-concrete jacketing, or steel plate bonding to restore structural integrity and extend service life. It is ideal for structures showing cracks, deformation, corrosion damage, or requiring higher load performance due to design modifications, ensuring improved strength, safety, and stability.
