Recently, in addition to greening of roof and artificial soil, Rootproofing to prevent damage to the waterproof layer and structures by roots is recognized as an important task. Therefore, various related products and construction methods have been developed and applied in the field. However, in the case of synthetic polymer-based sheets most commonly used in domestic construction sites, Most are produced using 100% new materials that are not suitable for green trends such as resource conservation and environmental protection. Therefore, in this study, we developed TPO sheet using recycled material, which is a technology that can secure eco-friendliness by utilizing recycled resources. As a result of the evaluation of tensile performance of the TPO sheet according to the recycled material content, The tensile strength of the specimens with the recycled content of 50 ~ 70% was the highest, The elongation rate of the specimen with the recycled content of 30 ~ 40% was the best.

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.

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.

Increase in use of deck plates is accelerated by a manpower shortage and the high cost of construction. Some of problems including fire resistance, waterproof, and low corrosion can be solved by development of new deck plates. This paper evaluates the structural performance of the LAMO Deck which metal laths instead of galvanized steel sheet is covered by mortar.

Due to various kind of waterproof materials and methods, which is difficult to select the most appropriate to waterworks. The materials used to prevent the deterioration of the service life is short, because of the chemical erosion. So, in the 2010 Office of Waterworks Seoul Metropolitan Government has set new standards. Recently, SMC panel is a trend that is being applied to water treatment facilities. However, SMC panel has not yet implemented a performance evaluation. Therefore, this study to confirm that satisfaction for the Office of Waterworks Seoul Metropolitan Government of the performance requirements, when the applied the SMC panel to water treatment structure.

The problem of water leakage due to damaging waterproof in concrete structure, causes the impediment in a long term and shortened the life span of durability. There are a lot of techniques for repair and reinforcement to improve using environment. However, the improper construction which is unconsidered various environmental conditions, could effect to increase the maintenance expenses. Therefore, this study will be compared and estimated the adhesion liquid and sheet integrate waterproofing material, as analyzing the existing problem. For those result, we would like to arrange the alterative plan for the long durability and user needs of concrete structure.

Recently, apartment houses are becoming more and more sophisticated and attention has been focused on the design of the interior of the bathrooms. As bathrooms always use water, the importance of waterproofing is very high. However, there continues to use the method that was used 30 years ago. And no one was trying to improve. It is necessary to be converted to a dry method, because waterproofing methods and materials have developed. Therefore, this study proposes the required performance before applying the dry waterproofing material to bathroom.

The exist waterproofing membrane cause not to assure proper thickness in constructing. It become a serious problem which as decreasing of durability, waterproofing membrane to be tom and break down. Therefore, it is necessary that the expert have to construct waterproof works,, if not, it can be frost and thawing or chemical corrosion called one of the reason in maintaining the safety of concrete structure. In summarize, for this paper, it would be understand that exposed and compound experimental study of waterproofing sheet using coat material filling into the protuberance to improve the durability for concrete structure can widely apply to field to solve the these significant problem.

Recently, As a part of urban forestation, the introductions of green roofs into public projects has been actively driven. Supported by this policy, the sizes of domestic green roof related markets have been rapidly expanding and many types of root barrier materials developed in Korea or abroad are being commercially distributed. In this study, root barrier tests were conducted over two years with nine types of sheet type waterproof materials that are the most commonly used as root barrier layers in green roof systems. The test conditions prepared considered the climates, natural features and vegetation in Korea and the results and related root barrier performance were verified. From the results of this study, the necessity to improve the joint part of root barrier sheets and forming methods has been identified and a measure to improve domestic root barrier testing methods was proposed.
