  • Retrofitting/ Strengthening of bottom slab and beam, girder using Carbon Fiber Sheet (CFS). Carbon Fiber Reinforced Polymer are lightweight, high strength systems for reinforcing concrete and masonry steel structures. This provides for a rapid construction schedule and a minimal disruption to an operating facility. Carbon fiber has gained wide-scale acceptability in the construction industry due to its strength, light weight, and cost-effectiveness. Carbon Fiber Sheet (CFS) composite material to add strength, last longer and ductility to structures.
  • 1. Removal of loose materials, and Concrete Plaster by means of chipping and grinding.
    2. Application of Carbon Fiber Sheet (CFS) with Chemical Epoxy resins
    3. Restoration of bottom slab, girder and beam on Affected by Carbon Fiber Sheets (CFS), and crack repair using epoxy injection Application
