Structural Strengthening

Common Strengthening method for strengthening of R C C structure is been carried by Jacketing, guniting and steel plate and steel plate bonding. These techniques are cumbersome, messy, time-consuming and labor-intensive. It also increases dead load; reduce usable space by increasing size of member & recurring maintenance.

But wrapping with advance fiber composite can eliminate all disadvantages of conventional technique. Following are it advantages:

  • It is very light in weight so increase in dead load is very insignificant (approx. 1 Kg per sqmt)
  • Faster and convenient application results in lot of time saving
  • It is highly durable material (major contain are epoxy and glass/carbon fibre)
  • It is does not corrode and inhibits future corrosion
  • Very little maintenance during service life
  • It enhance compressive and tensile strength of RCC by 40% to 50%

We have increase strength of various components of bridge (e.g Pier, Girder, Diaphram Girder and Bearing Pedestal) by wrapping.
