The traditional method of concrete repair is to remove the cracked and degraded concrete to a depth of 20 to 30 mm behind the reinforcing bars to fully expose the rusted reinforcement and move the contaminated concrete away from the steel. All corroded material is removed and the steel is either treated or replaced. Concrete repair mortars are then applied to the surface.
