Surgical Division > Composite Structural Strengthening


Structural strengthening systems include Glass Fibre Reinforced Fabric (GFRF), Carbon Fibre Reinforced Fabric (CFRF) and Carbon Fibre Plates (CFP) are best used for

  • Flexural capacity of beams & slabs
  • Column capacity/ductility
  • Shear strength
  • Stiffness
  • URM strengthening

Using Structural strengthening systems and connement techniques the capacity of the structure can be enhanced without increase in the sections of the components.


At Varthitha we can Design and execute Structural Strengthening systems with out trained manpower and Design Team.
