Retrofitting strengthens existing structures to improve their load capacity, durability, and seismic performance without full demolition. It is commonly used in aging buildings, structures with design deficiencies, or elements damaged by corrosion or overload. Column jacketing involves enlarging an existing column with additional reinforced concrete and steel reinforcement to increase strength and stiffness. This method significantly enhances the column’s load-bearing capacity and ductility. Wall jacketing is applied to structural walls to increase thickness and reinforcement, improving their ability to resist shear and lateral forces. Both techniques require careful surface preparation, including roughening and cleaning the existing concrete. Chemical anchoring systems are used to fix new reinforcement bars into the existing structure with high-strength bonding resins. These anchors create a reliable load transfer between old and new concrete elements. Specialized repair mortars or micro-concrete are then applied to complete the jacketing process. Retrofitting solutions extend structural life, improve safety, and offer a cost-effective alternative to rebuilding.
