In the present invention, disclosed is an integrated type complex waterproofing method using polyurea. According to the present invention, sheet blocks are prepared in advance by coating the surface of a waterproof sheet with a polyurea paint of a predetermined thickness using a low temperature and low pressure coating machine and assembled in fields. The connection gaps of the sheet blocks are bonded by a combining band, and the conventional top layer is coated on the sheet blocks and the combining band. Accordingly, the coating thickness of the polyurea paint is standardized, and scattering products generated from a polyurea paint coating operation in fields are prevented from contaminating vehicles or building outer walls around a coating operating place. Although the surface of a waterproof sheet is coated in case of rain, material property change of polyurea coated on the waterproof sheet, due to contact with rain, and coating quality reduction thereby are prevented, unlike the conventional coating method. Damage to a waterproof layer on the base layer of a concrete structure is prevented and the persisting life of the waterproof layer is extended. A complex waterproof layer can be constructed regardless of cracks or state of a base layer by arranging the waterproof layer on the base layer of the concrete structure in a non-contact manner. The waterproof properties of the base layer of the concrete structure are improved, and stress dispersion by the behavior of the base layer of the concrete structure reduces deviation on the height of the waterproof layer and minimizes a ponding phenomenon. |
