Over time, reinforced cement concrete (RCC) columns may show signs of stress, cracks, or reduced load-bearing capacity due to age, environmental exposure, or structural defects. RCC Column Jacketing Services provide an effective solution to restore and strengthen these critical structural members. Gubbi Civil Engineers Limited® specializes in offering tailored column jacketing services across India, ensuring durability, safety, and compliance with modern engineering standards.
What is RCC Column Jacketing?
RCC Column Jacketing is a structural strengthening technique that encloses an existing RCC column with further reinforcement and concrete or micro-concrete. This increases its load-bearing capability, ductility, and resistance to future degradation. Gubbi Civil Engineers Limited® performs this work with accuracy, resulting in little disturbance and long-term stability for both residential and commercial constructions.
When is Column Jacketing Required?
Column jacketing is recommended in a variety of scenarios:
- Deterioration caused by corrosion
- Overloaded structural members.
- Design flaws in the original construction.
- seismic retrofitting in earthquake-prone locations
- Structural damage caused by accidents or natural disasters.
Gubbi Civil Engineers Limited® does detailed structural examinations to decide whether jacketing is the best option for rehabilitation.
Types of RCC Column Jacketing
Depending on the requirements, a variety of jacketing procedures are used:
- Concrete Jacketing: Increases cross-sectional area using conventional concrete.
- Micro-Concrete Jacketing: Ideal for crowded reinforcement; made of high-flow, shrinkage-compensated material.
- Steel jacketing: Uses steel plates or pieces to provide extra confinement.
- FRP Jacketing: Uses fiber-reinforced polymers such as carbon or glass fiber for lightweight reinforcement
Gubbi Civil Engineers Limited® primarily recommends concrete and micro-concrete jacketing for Indian projects since they are compatible and cost-effective.
Step-by-Step Procedure of Column Jacketing
Gubbi Civil Engineers Limited® has a well-defined technique for successful jacketing:
- Structural assessment: Engineers use NDT and crack mapping to evaluate the column’s condition.
- Surface Preparation: Remove damaged concrete and clean the existing reinforcement.
- Formwork Installation: Moulds or shuttering are placed around the column.
- Pouring Concrete or Micro-Concrete: The material is carefully poured to fill the jacket evenly.
- Curing: Proper curing ensures strength and longevity.
This systematic approach ensures excellent performance with minimal maintenance requirements.

- Seismic Weaknesses: Bringing older structures up to new earthquake-resistant standards
FAQs: Understanding Column Jacketing Better
Q1: How long does it take to complete column jacketing?
A: The duration varies depending on the extent of the damage, although it typically spans between a few days and two weeks each area.
Q2: Can it be done without vacating the building?
A: Yes, the technique allows engineers to carry out the work while inhabitants go about their normal routines..
Q3: Is jacketing permanent?
A: When done correctly, jacketing can survive for decades with regular inspections and minor maintenance.
Q4: Is it suitable for seismic retrofitting?
A: Absolutely. RCC jacketing improves lateral strength and ductility, resulting in dramatically increased seismic resistance.
