The present invention is a composite waterproofing structure composed of an inorganic waterproofing agent applied to the upper surface of a concrete structure and a butyl self-adhesive waterproofing sheet, and the inorganic waterproofing agent applied to the upper surface of the concrete structure is 30-50% by weight of dihydrogen oxide, natural preservative 5-chloro 10-20 wt% of rho-2methyl-4-isothiazoline-3-one. The butyl self-adhesive waterproofing sheet, which is composed of 20 to 40% by weight of microcement, 10 to 30% by weight of quicklime, and 1 to 10% by weight of calcium carbonate, and covers the upper surface of the inorganic waterproofing agent, is an HDPE-based film laminated on the upper surface, , A butyl waterproof adhesive, which is a mixture of butyl rubber, inorganic fillers, tackifiers, modifiers, pigments and additives, is laminated on the lower part of the HDP-based film, and wet molded with PVA soluble in water on the lower side of the butyl waterproof adhesive An adhesion layer is formed, characterized in that a release paper is attached to the lower portion of the wet adhesion layer, Even if the moisture content of the curing requirements is not met after pouring concrete, it is possible to shorten the construction period by constructing a waterproofing construction type, and also significantly reduce the indirect construction cost accordingly. It is possible to prevent environmental pollution in advance by securing flame retardant performance and using an eco-friendly cleaning agent. In addition, by attaching a butyl self-adhesive waterproofing sheet to the upper surface of the inorganic waterproofing agent, even non-professionals can easily perform waterproofing construction, and the inorganic material and butyl self-adhesive sheet are laminated in a composite waterproof structure for perfect waterproofing can have an effect. |
