Introduction: Why Column Jacketing is Important
RCC (Reinforced Cement Concrete) columns are the backbone of any building. They carry loads from slabs, beams, and walls, transferring them safely to the foundation. Over time, columns may weaken due to corrosion, cracks, poor construction practices, seismic activity, or increased load demands.
If left untreated, damaged columns can lead to structural instability, safety hazards, and even partial collapse. The most reliable solution to restore and enhance the strength of such columns is Column Jacketing.
What is Column Jacketing?
Column jacketing is a structural strengthening technique in which an additional layer of concrete and reinforcement steel is provided around the existing column. This increases the cross-sectional area, load-carrying capacity, and durability of the column.
It is one of the most cost-effective and widely adopted methods for retrofitting and rehabilitation of RCC structures.
When is Column Jacketing Required?
Column jacketing is essential in situations such as:
Corrosion and Spalling – Steel reinforcement corrodes and concrete starts peeling off.
Increased Load Demand – When additional floors are constructed or usage changes increase loads.
Seismic Upgradation – To make existing structures more resistant to earthquakes.
Settlement or Damage – Columns affected by ground settlement, impact, or poor construction.
Under-Reinforced Structures – Old buildings constructed without sufficient reinforcement.
Step-by-Step Process of Column Jacketing
Surface Preparation
Remove plaster and all loose or damaged concrete from the column.
Reinforcement Cleaning
Expose steel reinforcement and clean rust using mechanical tools or rust removers.
Additional Reinforcement Fixing
Place new steel bars and stirrups around the existing column as per design specifications.
Bonding Coat Application
Apply epoxy or polymer-based bonding agents on the old concrete surface to ensure strong adhesion with the new layer.
Formwork Installation
Fix shuttering/formwork around the column, maintaining adequate space for new concrete.
Concrete Placement
Place high-strength micro-concrete or non-shrink concrete to encase the column and new reinforcement.
Curing & Finishing
Cure the jacketed column properly and finish the surface with plaster.
