The deterioration of our aging underground pipe network emerges as a critical problem. Concrete pipes may be damaged due to salt attack from outside and sulfide attack from inside, hence compromising its structural integrity. Repairs for such pipes are time-consuming and expensive. A revolutionary trenchless structural rehabilitation technique is introduced. In this technique Innovative honeycomb-FRP Composite Sandwich (HCS) are used for retrofitting concrete pipes (InfinitPipe™).
