It often happen water leakage that roof membrane have a poor condition such as direct exposed to rain, ultraviolet lays, temperature change compare with other part of waterproofing. There are difficult to maintain the quality of waterproofing and durability due to use only few waterproofing materials in practical in spite of development and use the various waterproofing material as solution of these poor condition. Therefore, in this thesis, I would like to know the property to apply field and suggest other method to develop for this waterproofing method to adopt various field condition for roof tops, as searching exposed and complex waterproofing technology for roof tops which is reinforced sheet using rising system have a regular pitch, depth, space.

The waterproofing of Building on the roof has been exposed more underground or the other part of waterproofing than environmental factor(solar heat, UV, salt, acid rain, wind, temperature, snow, rain, etc.) or physical factor. So it must be have a waterproofing performance and it has a special technique for the maintaining of concrete durability. Therefore, exposed waterproof layer has to protected from UV, solar heat, rain and the outside environment also, to endurance durability methods spread face plate topcoat material on the waterproof layer. But, actuality faceplate waterproof layer of topcoat materials are unbearable to UV, solar heat and moisture etc. and it doesn't have adhesion with waterproof layer in the middle. So it happens to crack, separating and heaving etc. Therefore, in the study, we will suggest that using of the exposed roof waterproof layer topcoat materials test method manage rooftop waterproof layer for the durability and the stability.

최근 건설시장 규모가 확대되고 교통산업이 발전하면서 지하철 및 터널 등과 같은 개착형 Box 혹은 Shield형 터널 구조물 등 지하구조물의 건설이 다양화되고, 그 수요도 점차 급증하고 있는 실정이다. 그러나 주로 지하에 건설되는 콘크리트 구조물은 시공시 신축이음 및 시공 조인트 등과 같은 다양한 형태의 조인트 발생과 구조물의 수축팽창에 따른 거동, 부동침하, 과다하중, 진동발생에 의한 균열로 인하여 누수가 발생되고 있다. 이에 다양한 방수공법 및 재료들이 현장에 적용되고는 있지만 지하철도, 지하철 등과 같은 진동 및 구조물의 거동이 상시적으로 발생되는 환경조건에서는 방수층의 성능이 저하되어 균열, 침식, 들뜸 등으로 물이 확산되어 재누수가 되는 악순환을 겪고 있는 실정이다. 따라서 본 연구에서는 진동 및 구조물의 거동에 대응 가능한 점착 유연형 복합방수공법을 대상으로 구조물의 거동 대응성 시험을 평가하고, 거동 및 진동이 상시적으로 발생되는 지하철, 터널 등을 대상으로 실제 현장에 적용 후 사례를 통해 구조물 거동에 대응 가능한 방수기술을 검토하였다. 이러한 거동 대응 특성을 검토한 결과 방수재가 기건 및 수중환경에서도 재료의 유연성과 부착성을 유지하여 물의 침투를 방지하고, 거동폭 $5.0mm({\pm}0.5)$ 범위에서도 거동에 대응 가능함을 알 수 있었다.

Although many waterproofing materials and techniques have been developed and applied, there is still a leakage in concrete structures. The main reason for the failure of waterproofing is due to the lack of consideration of the environmental conditions and the inconsistent performance requirement of the waterproofing materials in response to the complexity of the environmental conditions., and materials that are unsuitable to the environment are still being selected for usage due to their low price. Moreover, there is no valid test assessment for waterproofing materials to be used prior to actual application in the construction site. The development of a testing method and apparatus that can evaluate the composite waterproofing method is proposed in this paper and an interpretation method that can analyze the results of the evaluation.

The Composite waterproofing began to rise gradually 2000s in domestic. However, the sheet-membrane composite waterproofing method also acts as an abutment vulnerability that was a problem in a single method, and had the problem of damage to the formation of leakage paths. The existing non-overlap method, through vigorous research abutting sheet shall or could be developed to improve the seal performance of this method with the I-type joint coating material. Nevertheless, it has an integral top coat paint membrane and a sheet abutment limitation, damage to the upper membrane is damaged junction coating membranes has been generated. In this study, a method that has a layer of insulation on the joint bond breaker concept development, and to determine the physical properties with insulated joints to determine the breaking off of the upper joint is damaged coating membrane and tensile performance.

In mountainous area, Two parallel tunnels have been usually recognized as a road tunnel which has benefits in aspects of cost and stability. However, Design and construction of 2-Arch road tunnel are growing recently due to environmental destruction, compensation of land and difficulty of route separation. As studies are mainly undergoing on only guaranteeing stability and developing a waterproofing-drainage system to avoid water leakage through comprehension for characteristics of 2-arch tunnel behaviors, there is a tendency to evaluate quantity of support by empirical method with a tunnel which has a complicated cross-section and lack of construction ability. In this study, therefore, we made a plan of tunnel cross-section which had shown good construction ability and developed the waterproofing-drainage system which is able to solve the water leakage problem fundamentally by analyzing precedented 2-arch tunnels and investigating their sites in and out of nation. We also determined fixed quantity of support by a large-scale model test and numerical analysis. We want to contribute to 2-arch tunnel design hereafter introducing design procedure and method applied here.

성공적인 방수 시공을 위해서는 건축에 사용되는 방수재료의 재질적 성능뿐만 아니라 시공 품질을 확보하는 것이 매우 중요하다. 건설경기 침체에 따른 장기적인 원가절감 정책으로 인해 대부분의 건설사에서는 명확한 품질관리 기준이 없는 고급 방수 자재보다는 일반 저가의 방수 자재를 사용하고 있으며, 건설에 대한 명확한 교육 없이 건설 활동에만 의미를 두고 건설을 진행하고 있다. 또한, 복합적으로 적용되는 방수공법은 시공공법이 복잡하여 시공 품질이 부족하고 방수 불량으로 누수가 발생하는 상황에 놓여있으며, 성공적인 방수공사를 위해서는 품질관리 방안(설계, 자재, 시공)을 검토하고, 파생되는 문제점을 개선하여 안정적인 방수공사가 이루어질 수 있도록 하는 것이 필요하다. 건축물의 누수방지 효과를 기대하기 위해서는 먼저 설계단계에서 건축물의 각 부분과 환경에 적합한 자재를 선정하여야 하며, 선정된 자재는 한국산업규격(KS)의 모든 항목을 만족하여야 한다. 둘째, 방수시고의 품질을 확보하기 위해서는 작업자의 성실한 시공이 요구된다. 본 논문에서는 자재 선정 후 품질관리 대책으로 "방수 설계 검토", "시공자 교육", "현장실사", "비평(수정/보완)"에관한 현장점검 체크리스트를 제시하여 현장에서 안전 및 고품질의 방수공사확보를 위한 개선방안을 제시하였습니다.

Utilization of underground construction if increased by the large size ＆ skycraperlization of building recently. Therefore. waterproof dependence of underground construction is risen. However, water leakage was happened by rupture by concrete conduct, drying shrinkage. form tie. In underground environment soil class, degradation of waterproofing is showing to corrode by oil. An odious smell by oil, promotion evil of reinforcing rod corrosion, declination of durability can happen. Then, practical un degree of underground spare becomes low, Because oil or water permeates by construction by degradation to waterproof class corrode by oil, is considered to affect evil durability of construction.

The need for this study must be considerable, as being activate of green roofs research that the organization and construction obtain access to more development technologies. Nevertheless, the green roofs system has begun to apply since 1980's, the green roofs technology was restricted to develop without verification of technologies such as a load or water leakage. There is a limit as urethane waterproofing to almost domestic waterproofing materials and methods of construction for general green roofs. The introduction of materials and methods of construction which are appropriated to property of green roofs could be a decisive factor in a long-range durability and economical maintenance cost, moreover, it support to variety construction system and organization. This present paper describes a necessity of waterproofing and root barrier system is one of the sub-organization based on green roofs construction, which have enormously large impact on the durability.
