CONCRETE REPAIR work consists of STRUCTURE REPAIR and STRENGTHENING CONCRETE work.
STRUCTURE REPAIR work is the repairing of damaged concrete structures (e.g. concrete cracking, spalling, porous / honey-comb), so that the concrete condition returns to normal. STRENGTHENING CONCRETE work is the strengthening of existing concrete structures (e.g. due to function changes in a certain room), thus increasing the capacity of the concrete structure’s strength.
The first method used on STRUCTURE REPAIR work is injection method, used to repair cracks on concrete. The second method is patching method system, used to repair spalling concrete. The third method is grouting system, used to repair porous / honey-comb concrete.
On the other hand, the methods used on the STRENGTHENING CONCRETE work consists of Jacketing method, steel-plate, carbon-wrap and laminate systems.
