The present invention relates to a composite waterproofing method of a concrete structure and, more specifically, to a composite waterproofing method of a concrete structure capable of improving the construction efficiency and construction quality of a concrete structure by improving durability of a waterproof layer by complexly forming the waterproof layer by using various waterproof materials containing a primer, a coating waterproof agent, a waterproof sheet, and a reinforcement sheet when the waterproof layer is formed to prevent water from being penetrated through a crack of a wall when a concrete structure is formed. According to the present invention, the composite waterproofing method of a concrete structure comprises: a concrete structure forming step; and a composite waterproof layer forming step for forming a composite waterproof layer in the surface of a concrete structure after the concrete structure forming step. Moreover, the concrete structure forming step includes: a primer coating step for coating the surface of a concrete structure with a primer; a first coating waterproof agent coating step for coating the coated primer with a first coating waterproof agent; a waterproof sheet attaching step for attaching multiple waterproof sheets in the fixed form to the coated first coating waterproof agent, and attaching to allow lateral surfaces to be face each other and fixing by a fixing means; a second coating waterproof agent coating step for coating an outer surface with a second coating waterproof agent by containing a lateral surface connecting part of the waterproof sheet; and a reinforcement sheet attaching step of adding a reinforcement sheet to the coated second coating waterproof agent. |
