Concrete Repair & Rehabilitation

Structural Rehabilitation & Retrofitting

Rehabilitation & Retrofitting are very daunting tasks which involve visual inspection of the structure, detailed analysis and to provide effective solutions.

 

Our team follows best practices and has tested methodologies in providing durable and long-lasting solutions. Combined with great experience, skill and use of latest technology, we find areas to be fixed based on scientific analysis. Based on the project study and analysis report, NVLN comes up with a solution that provides a right fix to the problem in the most cost-effective model.

 

Here are the few techniques giving the vivid picture of various methodologies that we use for retrofitting purposes.

 

  • Micro Concrete Jacketing

 

  • Shotcreting/Guniting

 

  • Steel Plate Jacketing

 

  • Protective Coatings

 

  • High-Performance Concreting

 

  • Epoxy Injection Groutings.

Composite Structural Strengthening

The use of FRP to existing structural elements is one of the dominant alternatives to traditional strengthening techniques.

 

Our solutions include FRP techniques using Carbon Fiber Reinforced Polymer (CFRP) and Glass Fiber Reinforced Polymer (GFRP). We execute both EBR and NSM techniques.

 

Based on our study and analysis we develop active solutions for the most complex strengthening challenging with a range of combinations.

 

Advantages:

 

  • FRP –ER acts as reinforcement in tension zone (in beams).

 

  • FRP-ER enhances flexural strength and stiffness (in beams).

 

  • For depth limitations in beams or when high demands of ductility are needed, we can use FRP.

 

  • Faster field installation, higher stiffness and strength.

 

  • Increasing the shear strength of in-service concrete members.

 

  • Enhances the service life of concrete members.

 

  • FRP composites are resistant to Corrosion, Can be used in Marine applications also with greater ease because of higher strength to weight ratio.

 

  • FRP –ER confines the concrete which reduces tension cracks.

 

  • Can be customized depending on the requirement.
