Earlier we used to call it as JACKETING. Its generally done to increase the size of the compressive member which may have been underdesigned or needs additional strengthening. Nowadays this is replaced with new technology also called as FIBRE WRAPPING, GLASS FIBRE WRAPPING, CARBON WRAPPING ETC.

once reinforcement is laid then the said area is micro concreted after formwork is laid in place.
