Description

Composite waterproof structure with coupling holes and construction method thereof The present invention relates to a composite waterproofing structure using connecting holes and a method of constructing the same. More specifically, it relates to a composite waterproofing structure in which each component interacts to maximize waterproofing performance and enhance construction convenience and durability, thereby compensating for the disadvantages of existing waterproofing methods and ensuring long-term stability and excellent waterproofing effects. Conventional waterproofing systems tend to rely primarily on a single material, resulting in limited waterproofing effectiveness and physical strength. Due to a lack of resistance to displacement, these systems are highly likely to experience a degradation in waterproofing performance over time. In addition, there was a problem where displacement could occur at the joint with the primer due to the weak bonding strength between the asphalt sheet and the base concrete. This reduced structural stability and made it difficult to guarantee long-term waterproof performance. In addition to issues with bonding strength and long-term waterproofing performance, the overall efficiency of the waterproofing system was low due to insufficient protection from the external environment. Furthermore, the lack of additional measures necessary to prevent water penetration into the base concrete entailed many problems, such as shortening the lifespan of the building and increasing maintenance costs.
