Abstract: Major problem in the construction industry is deterioration of concrete structural elements. Replacement of deficient structural elements is uneconomical and inconvenience due to interruption of function of the structure. It is often better to upgrade the structure by retrofitting. External strengthening has become an acceptable way of improving the load carrying capacity of the existing structure. The present study intended to develop a technique of retrofitting of RCC beams, using geonet. In this study biplanar geonet was used as an externally bonded material. Prior to retrofitting, the specimens were subjected to different levels of distressing, 67%, 80% and 90% of the flexural capacity of control specimen. The flexural behaviour of control specimen and retrofitted specimen were studied. From the result obtained, a significant improvement in load carrying capacity was observed, which depends upon the distressing level.
