개량 아스팔트 방수시트 위에 폴리 우레탄 도막방수재가 도포되는 복합방수공법의 경우 시공성 향상을 위하여 도막 방수재에 유기용제를 희석해 사용하고 있지만, 유기용제가 폴리 우레탄 도막방수재의 완전 경화 전에 전부 휘발되지 못하고 시트재와 도막재 사이에 잔류하게 되고 이는 아스팔트 층을 융해시켜 방수층 손상 및 누수문제를 발생시켰다. 이에 용제에 의한 융해 문제를 개선하기 위해 내용제성이 강한 PA 필름을 개량 아스팔트 시트에 코팅(적층)하였고, 그 결과 융해에 대한 안전성을 육안을 관찰하였고, SEM 분석, EDX 분석을 통하여 PA 필름에 대한 내용제성을 정량적으로 확인하였다.

This study started to confirm and prove for the applicability of the dry-process waterproofing system to cover the defects of the wet-process waterproofing system according to weather circumstance, foundation condition and maintenance, etc. This process has triple combined waterproofing system using asphalt sheet, metal sheet, engineering plastic film. It is not influenced by the concrete's crack as the foundation of the roof according to the movement of the building because the waterproofing system is designed for maintaining good quality by absorbing the stress of contraction and expansion that is occurred by the variation of temperature. Ali components used in this process can be recycled environmentally. The superiority of this process proved and reconfirmed through with the investigation of about 130 fields, around 30,000nf for two years.

New waterproofing technologies have emerged in the field of building waterproofing due to the recent diversification of the size and type of structures, the enhancement of required performance, and the diversification of new technologies (such as materials and methods)(Sheet waterproofing material, coating waterproofing material) is reduced, and composite waterproofing materials that utilize mutual benefits are widely used by compounding them (sheet+coating film, coating film+sheet). However, it is true that there is no evaluation method that can verify these composite waterproof materials, which is the most widely used at present, but the KS standard only specifies tests for individual materials However, there is a situation in which the countermeasures without a test method for composite waterproofing become sudden.

Integrated water-soluble film is dissolved in the rubber asphalt waterproof sheet to secure adhesive strength on freshly cast concrete on the adhesion side of waterproofing layer on the floor slab. In addition, in order to determine whether the water in the concrete slurry can dissolve the water-soluble film sufficiently, the adhesive strength of the waterproofing sheet was compared between difference wetness condition at the upper part of the concrete specimen before the concrete casting.

Engineers in the construction field have been using bonded waterproofing sheets in an attempt to resolve the imbalance in the quality, the risk of fire, safety of workers, and environmental pollution, as well as to eliminate separate use of organic adhesives on the surface of concrete. Recently, self-laminated waterproofing sheets have been developed. The purpose of this research is to find an appropriate processing speed according to the changes in physical properties, and visual observation of the waterproofing sheets laminated by the aluminum thin-film and viscosity layer that can be attached through self-adhesiveness on the surface of concrete and waterproofing sheets. Therefore, this research is conducted using a physical performance test. Based on the result of the test, when the high-frequency inductive heating apparatus was used, an improved adhesion and bonding stability effect were confirmed after the anti-hydrostatic pressure and bond strength in the temperature condition, and the surface observation in the processing speed condition.

This is a double Composite Waterproofing Method of Mastic Asphalt Film ad Sheet(MAS) on concrete structure and its working method. MAS is characterized as having excellent strength and adhesion to concrete. To make a good waterproofing system, it is needed the information on the performance tests. The designer should choose a material that can be applied in almost all conditions. During their service life, Underground spaces have been keeping to dry enough for habitable or utilitarian used. This method is of use for waterproofness in various spaces.

In securing durability of underground structure non-exposed waterproof materials, the company aims to improve durability of waterproof materials by studying more realistic weather conditions than KS standards and developers' durability standards. Analyzing the actual climate data in Korea and the temperature of the basement layer, it is a waterproofing sheet method, a self-adhesive sheet method in which a film and a compound, which are currently widely used as underground water-proofing, and a self-adhesive waterproofing sheet method, etc. We would like to present the guidelines necessary to prevent the temperature situation and waterproof defects that are ideal for setting the endurance conditions later.

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. In this paper I focused to assure the basic system for waterproofing materials and root barrier apply to green roof as searching the application of field condition. And I suggest proper waterproofing and root barrier as considering the mutual connection and plant growth. and it can be a standard model to adopt to domestic green roof system.

Safe, economical and environment-friendly tunnel construction are required again along with social continuous development, the importance of waterproof work that is portion that actually all of user and builder can find that is embossed by tunnel construction's one of important construction. Also, ECB (Ethylen Copolymer Bitumen) sheet that is used in existing tunnel waterproofing method (ECB waterproofing method) being black because asphalt (Bitumen) is added, by purpose that make illumination of tunnel interior brightly and scar discovery eases in sheet with coating white film, but ECB that is used present according as ECB that asphalt is added does not satisfy high tensile strength of construction field, quality standard of extension. Also ECB denigrates color of black M/B that asphalt is excepted.

본 연구에서는 보편적으로 건물의 옥상 등에 사용되는 폴리 우레탄 방수재의 바탕구조물의 함수정도와 시공환경조건에 따른 하자원인을 분석하기 위한 것으로 바탕판의 함수조건에 따른 부착강도, 표면상태를 육안관찰하였고, 온도, 습도의 양생조건에 따라서 방수재 도막의 기계적 성능을 평가하였다. 실험결과 바탕판의 함수상태가 10%이상일 때 도막의 부착이 이뤄지지 않음을 확인하였고, 온습도 조건이 20℃, 80% RH일때는 기초물성이 모두 확보되었으나, 40℃, 60% RH일 때 표면에 기포가 관찰되었으며, 40℃, 80% RH일 때 건조도막 기초물성이 KS F 3211 성능기준이하로, 우레탄 방수재 도포에 있어 시공환경조건의 하자원인 중 바탕판의 함수조건 및 양생 시 절대습도가 중요한 요인임을 확인하였다.
