Concrete Repair and Reinforcement Method

16ddcd48b92a40a206a35d2a6a0b739b_1598863281_28.pngOverview of Raphah System  


 The word ‘Raphah’ from the Raphah system means ‘to cure’ in Hebrew and it is a system for repairing and reinforcing deteriorated concrete through basic curing principles.

This system is an inorganic repair and reinforcement method which has improved workability and economic efficiency through curing underlying causes with chemical and physical solutions, in order to repair and reinforce concrete structures deteriorated due to neutralization, salt damage, chemical corrosion, copper sea, alkali aggregate reaction, etc.

The Raphah system is a concrete repair and reinforcement method containing chemical solutions which features alkali recovery from inside concrete and inhibition of activities of chlorine ions in concrete, rather than  simply depending on physical repair of organic systems for improvement of durability. 

 In other words, the Raphah system is an inorganic repair and reinforcement method for doing re-alkaliation of neutralized concrete through applying an alkali restorer to neutralized concrete and, at the same time, preventing future neutralization and salt damage through strengthening vulnerable layers of the surface and applying inorganic polymer mortar.

(1) As an inorganic system that is the same as the matrix concrete, it has the same structural behavior and has the same life span as the matrix concrete, and fundamental repair is possible when it is used.
(2) It is an inorganic repair and reinforcement system with excellent compressive strength and bending strength, and workability, durability and adhesion of the system have been maximized.
(3) The system can be used for wet surfaces, can easily restore large sections, can easily do spray mechanization, and can shorten the construction period. 
(4) The system is highly economical in terms of materials and construction.
(5) Obtaining KC certification, the system can be adopted for water and sewage facilities and water conservation areas.
