Retrofitting & Repairing Service

What is Retrofitting in Construction?

Retrofitting & Repairing Service is the process of upgrading and strengthening existing structures with new materials, technology, or equipment. This method is essential for improving durability, safety, and efficiency. It is widely used in buildings, bridges, and other infrastructure that may have weakened due to aging, environmental exposure, or construction defects.

Retrofitting helps meet updated building codes, enhances energy efficiency, and strengthens structures against disasters like earthquakes and floods. Common retrofitting techniques include reinforcing foundations, installing insulation, and upgrading electrical and plumbing systems. This process ensures the long-term stability and safety of structures.

Advantages of Retrofitting & Repairing Service

Over time, buildings degrade due to weather conditions, structural weaknesses, and outdated construction standards. Retrofitting & Repairing Service provides a cost-effective solution to restore and improve these structures without the need for demolition.

Key Benefits of Retrofitting & Repairing Service:

• Enhanced Structural Strength: Improves resistance against earthquakes, storms, and other hazards.
• Energy Efficiency: Reduces energy consumption through better insulation and modern HVAC systems.
• Cost Savings: Extends the building’s lifespan and prevents costly future repairs.
• Sustainability: Reduces waste by upgrading old structures instead of replacing them.
• Regulatory Compliance: Ensures buildings meet current safety and environmental standards.

Retrofitting & Repairing – Column Jacketing Procedure

Jacketing is a widely used retrofitting technique to strengthen columns and restore their load-bearing capacity. It involves adding new materials around the existing column to enhance its durability and structural performance.

Steps for Jacketing of Columns:

1. Assessment & Planning:
   • Conduct a structural analysis to assess the extent of damage.
   • Prepare detailed designs and specifications for the jacketing process.
2. Surface Preparation:
   • Chisel the surface and remove plaster, loose, or deteriorated concrete.
   • Ensure sufficient propping as per the consultant’s recommendation before chiseling.
3. Reinforcement Placement:
   • Anchor the main bar as per structural drawings using La Barfix.
   • Fix shear connectors using La Barfix as per structural design.
4. Bonding Agent Application:
   • Apply an epoxy-bonding agent (La Bond EP) over the prepared surface using a brush.
5. Formwork Installation:
   • Set up shuttering around the column.
   • Seal gaps between the formwork using La Terra Plug to prevent leakage of micro-concrete.
6. Concrete Application:
   • Mix micro-concrete (La Struc Rep MC 40/60/70/80) with a water-powder ratio of 0.16-0.18.
   • Pour the micro-concrete into the formwork.
7. Curing & Finishing:
   • Remove the formwork once the concrete has set.
   • Spray curing compound (La Curecrete WB) or cure with water using the conventional method.
8. Quality Inspection & Testing:
   • Conduct load and non-destructive tests to ensure effectiveness.
   • Address any defects found during the inspection.

When Should Retrofitting & Repairing Service Be Considered?

Retrofitting is essential for improving structural stability, extending lifespan, enhancing safety, and upgrading buildings to meet modern standards. Including necessary:

• Aging Infrastructure: Cracks, leaks, or weak foundations indicate a need for reinforcement.
• Disaster Preparedness: Essential for buildings in earthquake, flood, or hurricane-prone areas.
• Regulatory Compliance: Necessary when building codes are updated.
• Energy Conservation: Helps reduce electricity costs with modern energy-efficient systems.
• Post-Disaster Repairs: Required after natural disasters to restore safety and integrity.

Conclusion

Retrofitting & Repairing Service is a crucial investment to improve building strength, efficiency, and safety. It helps extend the lifespan of structures, enhances durability, and ensures long-term cost savings.
