The earthquake stroke Sabah in 2015 have given an alarm to structural engineers on the importance of ensure concrete structures to resist seismic load. The damaged column due to the seismic load needed to be repaired. Research and development of rapid repair techniques have emerged as one of the most critical researches globally as the money spent on repairing damaged structures are more than the cost of building new structures. Confinement is one of the popular and effective rapid repairing of damaged concrete under cyclic loading. This paper reviewed the uses of confinement as a repairing technique to facilitate the research development in this field. The findings have proven that confinement repair techniques are effective and can restore the original capacities of damaged concrete members.
