Repair and Rehabilitation: Strengthening Structures for Longevity
Repair and rehabilitation have become crucial aspects of modern infrastructure management. With aging buildings, bridges, roads, and industrial facilities worldwide, ensuring the safety, functionality, and sustainability of existing structures is just as important as constructing new ones.
What is Repair and Rehabilitation?
Repair refers to restoring damaged or deteriorated structures to their original condition or functionality. Rehabilitation goes a step further, involving modifications and upgrades to improve performance, extend lifespan, and often comply with updated standards or new usage requirements.
Key Methods and Techniques
Common repair techniques include crack injection, patching, grouting, and replacement of damaged components. Rehabilitation may involve structural strengthening using fiber-reinforced polymers (FRP), steel plate bonding, jacketing, or advanced concrete overlay systems. Techniques like cathodic protection are also used to prevent further corrosion, especially in reinforced concrete structures.
