Concrete Repair
Normally, repairs of any structure are carried out under the following methods :

• Inspection of the original state of the structure by testing the quality of the materials as well as analyzing the bearing capacity of the original structure to find the cause of the problem and ways to provide proper solutions.
  
• Repair of structure according to result of inspection, using appropriate materials and solutions, as well as find ways to prevent recurrence.
  
• Appropriate efficacy testing of ongoing structural repair  
  

Nowadays, most buildings and factories in operation or under construction have steel reinforced concrete structures.  Therefore, a problem which often arises after long usage mostly concerns corrosion of the reinforced steel which has accelerated so extensively that the concrete cover for the steel cracks and the structure can no longer be used safely.

The method to repair reinforced steel concrete structures is therefore focused on how to solve the problem of reinforced steel corrosion and prevent recurrence as follows:

• Halting the corrosion process 
  
• Reinstating the concrete 
  
• Protecting against renewed corrosion 
  

After having analyzed the structure and finding that the damaged structure cannot bear the required capacity or wanting to increase the structure’s bearing capacity, the structure can be reinforced by a new technology called CFRP system (Carbon Fiber Reinforce Polymer). 

And in order to prevent renewed corrosion in the long run, a new corrosion prevention system called Galvanic Cathodic Protection System and ZLA (Zinc Layer Anode) can be used.
