Column Jacketing for Structural Strengthening: Process and Benefits
Column jacketing is one of the most effective structural strengthening techniques used to enhance the load-bearing capacity and durability of existing buildings. Over time, columns may weaken due to increased loads, poor construction practices, corrosion of reinforcement, earthquakes, or aging infrastructure. Professional column jacketing services help restore structural integrity without demolishing the building.
What is Column Jacketing?
Column jacketing is a structural repair method in which additional material such as reinforced concrete (RCC), steel plates, or fiber-reinforced polymers (FRP) are added around an existing column. This process increases the cross-sectional area, improves confinement, and enhances axial and lateral load capacity.
Types of Column Jacketing Techniques
1. RCC Column Jacketing - Adding reinforced concrete layer with new steel reinforcement.
2. Steel Jacketing - Wrapping steel plates around columns for improved strength and ductility.
3. FRP Wrapping - Using carbon or glass fiber reinforced polymer for lightweight strengthening.
4. Concrete Encasement - Increasing column size to support additional floors or loads.

When is Column Jacketing Required?
Column jacketing is recommended when structural audits identify cracks, reinforcement corrosion, insufficient column size, increased load demand, foundation settlement, or seismic vulnerability.
