Waterprooping Method with sheet need to study technology and multilateral verification considering the arctic conditions as low temperature and humidity, which is the result only considered of material aspects without environmental condition in construction But there are no measures up until now. To solve this problem by using high frequency induction heating method developed waterproof sheets, cold (5 ℃ or less) can be applied in a more stable environment, water-resistant materials and construction methods were studied for development. The results of the test showed that high frequency induction heating method is effective for usability in low temperature condition and securement of proper quality than existing Waterprooping Method with sheet need.

The combined waterproofing method is an excellent method to overcome the disadvantages of the single waterproofing method by composing two or more materials to complement each other, but it is a method that can cause defects such as separation and peeling between materials due to the heterogeneity of the applied two materials. In order to improve this, in this study, we aimed to develop a technology for inducing chemical unification between materials through a urea reaction with a coating material applied on the lower side by laminating a nonwoven fabric treated with a modified amine on the back surface of the sheet material, The adhesion performance test was carried out with the presence or absence of denatured amine treated nonwovens as variables. As a result of the test, it was confirmed that the adhesion performance of the specimen to which the modified amin - treated nonwoven fabric was applied was improved by about 60% or more as compared with the specimens not having the denatured amine treated specimen.

This is green roof bottom system which composed by aluminum valve and glass fiber together as major reinforcement, so the cooper sheet can have root proof, and using recycled tire gel-type membrane waterproofing system which dost not contains VOCs. The copper sheet reduce the plants' root growing, so it helpes to maintain the waterproofing layer and stability of root proofing. Gel type membrane waterproofing system can do waterproofing, stress dispersion, and reducing leakage expansion. So those two materials can help each other to make green roof bottom layer would have the stability and durability.

This technology employs a method of forming a single-ply PLUS waterproofing sheet layer comprised of applying a single-ply synthetic polymer layer on a vibrating structure (steel frame, RC) or an inclined surface by using a T joint lap-filling coil and an embedded metal coated sheet. The T - joint reinforcing lap-filling coil was used to block the ingress channel of the rainwater by applying the material in the vulnerable area where the three sides of the waterproof sheet overlapped. Conventional waterproofing techniques have a problem in that the waterproof sheet is pierced because the end portion of the waterproof sheet applied to the vertical portion is fixed by a nail, and the sealant applied to the end portion of the sheet cannot easily secure long-term waterproof durability due to the influence of the external environment. Therefore, the developed technology secured the waterproof durability against the vertical part by using the embedded metal sheet. In addition, automatic hot-air fusing is used to improve the quality of waterproof construction and point fixation method using fixed hardware. This is a technology that is not significantly restricted in the high degradation level regions of domestic waterproof construction environments in Korea such as low-temperature environment, wet floor.

건축물의 대형화, 고층화에 따라 지하 구조물이 증가하고 있으며, 지하상가 및 지하철 등 지하구조물의 활용도 및 용도가 다양해지고 있다. 이에 따라 지하수 영향으로 인한 지하 구조물의 보호를 위해 다양한 방수 공법이 개발되었다. 그 중 대표적으로 방수층이나 외벽방수의 품질 확보와 구조물 거동에 대한 하자 발생률을 줄이고자 아스팔트 씰과 아스팔트 방수시트를 복합으로 사용하는 복합공법이 지하주차장 및 지하구조물의 외벽 중심으로 국내에서 널리 사용되고 있다. 그러나 일부 건설 현장에서 기온이 높아지는 여름철에 외벽 시공된 아스팔트 씰재가 층분리되어 건축물의 균열부를 통해 내부로 흘러들어가는 누유현상이 발생되었다. 본 연구에서는 콘크리트 구조물의 계절변화에 따른 온도 특성을 파악하고 이 결과를 바탕으로 옥외와 실내에서 온도 변화에 따른 아스팔트 씰재의 특성을 확인하여 품질 기준 을 설정할 목적으로 연구를 진행하였다. 연구 결과 여름철 콘크리트 구조물 온도가 최고 $51^{\circ}C$까지 상승하며, 슬래브에 시공된 방수재료의 경우 $54^{\circ}C$까지 상승하는 것으로 나타나 콘크리트 표면보다 방수 재료의 온도가 $3^{\circ}C$ 높은 경향을 나타냈다. 옥외 콘크리트 구조물을 대상으로 한 흘러내림 특성 실험 결과 수분산형의 경우 수분의 증발이 늦고 낮은 점도로 인해 다량의 흘러내림이 발생되었으며, 실내 촉진 흘러내림 특성 실험 결과 용제형과 수분산형의 경우 상온에서의 점도가 낮고 용융점이 낮아 다량의 제품에서 흘러내림이 발생되었다. 이상의 결과로부터 점도와 용융점이 아스팔트 씰재의 품질 특성에 큰 영향을 주는 것을 알 수 있었고, 점도와 용융점에 관한 정량적 수준을 결정할 필요성이 있다.

It has been found that existing detects at the junction between waterproofing layer as well as the material and the surfaces of the construction when waterproofing sheet is employed in the currently used unground structures waterproofing technology, causing a series of problems such as the high cost to the maintenance for leakage and the durability. The purpose of this study is about reducing the waterpoofing defects in underground structures. consequently, the homogeneous sheet which has some quality such as the unvulcanizate, high-adhesion and high-elastic was examined on physical properties. As a test result, it was confirmed to have satisfied performance about the ks. However, it must be continued to study through mock-up test for confirming of site application.

본 연구에서는 공동주택의 주요 하자발생 부위인 지하주차장을 대상으로 부위별 누수원인과 보수방안에 대하여 검토하였다. 지하 1층 상부 슬래브의 누수 원인은 슬래브 상부에 조경과 같은 중량물이 설치되고, 공사 중 혹은 기타 요인에 의한 구조물 거동 시 바탕면에 균열이 발생됨에 따라 방수층이 이에 대응하지 못하고 파단되어 누수가 발생된 것으로 판단된다. 보수로는 합성고무계 폴리머 겔을 사용한 방수층 재형성 공법이 안정적이라 판단된다. 층간 슬래브의 경우 수팽창성 아크릴주입재를 사용하여 보수하며, 그 밖에 차량 진출입구는 시트+겔을 복합화한 복합방수와 폴리우레아 시공이 안정적이라 판단된다. 기초바닥과 지하외벽은 지하수의 수압(양압력)이 가해지는 부위로써 일반적으로 합성고무계 폴리머겔을 이용한 배면보수가 효과적이지만 수압이 높아 차수층 형성이 요구되는 시공구간에 대해서는 무수축 시멘트 밀크 그라우트재로 차수막을 형성시킨 후 구조체의 균열부에 수팽창성 아크릴재로 주입보수하는 것이 효과적이라 판단된다.
