일반적으로 콘크리트 건축물 옥상의 누수원인은 구조체의 결함에 의한 균열 및 거동에 의해 방수층이 손상되거나 방수층이 노화되어 바닥면과 들뜸현상이 일어나, 손상된 방수층사이로 유입된 물은 방수층과 바닥면과의 들뜸사이로 확산 이동, 구조체의 결함을 통해 누수가 되는 것이다. 이러한 누수현상은 시간이 경과함에 따라 자연적인 발생현상으로 주기적인 방수보수가 요구되고, 다양한 방수재료와 공법이 제공되고 있다.In general, the cause of leakage on the roof of a concrete building is that the waterproofing layer is damaged or the waterproofing layer is aging due to the cracking and behavior caused by the defect of the structure. Diffusion movement, leaks through structural defects. Such leakage phenomenon is a natural occurrence phenomenon over time, requiring periodic waterproof repair, and various waterproof materials and methods are provided.
방수하자보수시 비노출식 공법은 손상된 방수층과 보호 콘크리트층을 철거하여 새로운 방수층과 보호 콘크리트층을 재시공하며, 노출식 공법은 보호 콘크리트층을 철거하여 이를 재시공하여 양생한 후, 완전히 건조된 상태에서 바닥의 레이턴스 제거등 바닥면을 정리하여 프라이머를 도포, 상부에 도막방수제등을 사용하고 있다. Non-exposed method removes the damaged waterproof layer and the protective concrete layer during the repair of the waterproof defect, and reconstructs the new waterproof layer and the protective concrete layer.The exposed method removes the protective concrete layer and reconstructs it to cure, and then the floor is completely dried.
