Rehabilitation of Structures is changes done to existing structures to increase the overall strength of the building. Retrofitting of Structures is necessary to prevent further damage to concrete constructions which are more vulnerable to earthquake and failures by seismic forces. Retrofitting of structures is one of the best options to make an existing inadequate building safe against future probable earthquake or other environmental forces.
Retrofitting of concrete structures becomes necessary for old concrete structures that are more venerable to earthquakes. Retrofitting of Structures is the process of strengthening of structure along with the structural system, if required so as to comply all relevant codal provisions in force during that period. Retrofitting of concrete structures of repair or retrofit solutions should address the main performance challenges in the structure, be performed with minimum intervention, and stay economical. It helps to increase the strength, resistivity and overall lifespan of the structure.
Retrofitting of RCC structures should start with investigation and diagnosis of cracks and then by applying suitable retrofitting measures. The structures process involves repair, retrofit, renovation and even part reconstruction.
Retrofitting Techniques :
We provide various methods of Retrofitting of RCC structures like
Spray Polymer – Ready to use cement based sprayable polymer mortar for High Early strength recommended for use in Reinstating of columns, cement silos and chimneys, retaining walls, water front structures, dams, irrigation canals, tunnel linings etc.
Carbon Fiber Wrapping– Carbon Fiber Wrapping is used for structural strengthening of weaker concrete members, like concrete columns, beams, etc. The process of Fiber Wrapping Columns or beams uses structural carbon fiber.
Carbon Laminate– Carbon FRP “Laminates” are used to strengthen existing RCC, wood or masonry members, structurally. Carbon Laminates are used to correct a structural defect in structural members.
Micro Concrete Jacketing – Micro concrete is the ready to use, self flowable mixture generally made under strict quality control in automated factories
Polymer Modified Mortar – To be applied where structures have deteriorated due to corrosion and where changes in use and/or design code do not demand increase in loading capacity.
Epoxy Mortar – A three-component, water-washable 100% solids epoxy mortar system for exceptional high-strength and chemical and impact resistance.
