THE WATERPROOFING STRUCTURE BY PROTECTIVE MORTAR SURFACE'S REINFORCEMENT AND THEREOF METHOD

In the present invention, a rooftop waterproofing structure having a waterproof protection layer and a construction method thereof are disclosed. The present invention is configured to protect a waterproof mortar layer by the waterproof protection layer made of slag composed of a porous layer, thereby being useful for cooling and heating due to the low heat generation and protecting the waterproof layer even in harsh environments, and maintaining durability for a long time. The construction method of the rooftop waterproofing structure comprises (a) a process of evenly organizing a concrete layer (10) of a rooftop floor and primarily constructing a waterproof mortar layer (20) on the organized concrete layer (10); and (b) a process of secondarily constructing a waterproof protection layer (30) on the surface of the waterproof mortar layer (20). 본 발명은 방수 보호층을 가지는 옥상 방수 구조 및 그 시공법을 개시한다. 이러한 본 발명은 다공층으로 구성된 슬래그로 이루어지는 방수 보호층을 통해 방수 몰탈층을 보호하도록 구성한 것이고, 이에 따라 저발열성으로 냉,난방에 유용하고 혹독한 환경에서도 방수층을 보호할 수 있도록 하는 등 내구 수명이 장기간 유지되는 것이다.
