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.

To build up the green roofs, it must not adverse effect to durability and structural safety. That is conducted by safety system which consist of waterproofing to form basically, root barrier to protect the waterproofing. The reason why root barrier form is to protect the penetration force of root growth and the root could penetrate concrete surface, move inward so far. It may cause shorten the life span on concrete structure. For this problem, government constantly demand the solution to form the root barrier for waterproofing and concrete structure before the building is service. However, the technical action is not fully prepared. Therefore, in this study, we would like to suggest the workability and suitability of the copper plate to solve not only the side of waterproofing but also root barrier for green roof system and exhibit the mechanism for root penetration resistance and corrosion resistance.

Waterproofing is one of the important factor to improve performance of building elements. But existing repair system for waterproofing have many problems like a damage of waterproof layer due to movement of concrete substrate, blistering effect and moisture condition. So waterproofing layer can not play an important part to improve waterproofing function and performance of building. Therefore, new waterproofing system to solve these problems of existing waterproofing system is developed. In this paper, new waterproofing system in water-leakage repair for remodeling is introduced

In addition to the waterproof sheet waterproof objectives that apply to the building roof it is being constructed, including a complex such as insulation performance, root-resistance. However, thermal insulation of the composite waterproofing sheet is an insulating effect a wide variety depending on the specific construction -specific, material and even the effect is this part of the test to the generation when insignificant compared to each other a number of roof insulation effect of the insulation composite waterproof sheet that is currently in effect analysis.

Cool roof coating materials generally use white color which has the highest reflectance, but it is a tendency to apply various colors because it can cause glare and fatigue of a nearby building user due to the urban beauty and high reflection. This study when applying color diversity material cool roof coating was carried out as a basic research for the degree of solar radiation reflectance change. Experiment result. As a result of the measurement of the reflectance of each specimen, white showed the best reflectance in the near infrared region, and black had the lowest reflectance. Also, in case of brown, it was confirmed that the reflectance of solar radiation in the near extrinsic region is lower than that of gray.

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.

In this study on the appliable Asphalt sheet of monolithic and inorganic matter waterproofing material using of field because of problem of complex waterproofing sheet. Before this cement polymer modified waterproof coating and appliable asphalt sheet of monolithic whether have stability by method of construction about all style waterproofing that evaluate to new method of construction development naturally big emphasis put and try to approach. Did performance test item first at, as a result, drew by suitable thing in all KS items. This is considered to have more effective spot construction work because if means that have stability by material as well as method 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.

We divided the planting bale into waterproof layer, drainage layer and soil layer so at to investigate changes of live load according to species of wood and composition of the base to make rooftops green. The results are follows, 1. As concerning construction and live load for green roof, sheet waterproofing is superior. 2. When materials of drainage are changed crushed gravel into artificial lightweight graval or ferrite, live load of planting bale is decreased about 22% and 25% in order. 3. When ingredients of soil are chased normal sand into volcanic sand, live load of base is decreased about 28%. Especially, when it is changed into ferrite, 54% of live load is decreased. 4. In this study, all live load we concerned excesses the standard about roof live load of office, school and house. Hence, structure has to be concerned thoroughly when making rooftops green. But, we judge that various methods for making rooftops green can be applied if we consider roof garden when we plan new buildings.

This study deals with the characterizing and the application like as insulation materials in the joint part in concrete surface layer and waterproofing sheet especially for roof slabs. Using steel materials and butil-rubber tape to band waterproofing sheet and concrete surface together before this waterproofing system will be applied. It can be expected to both the curability and the watertightness by coating poly-urethane 2 or 3 times with sheet surface. Therefore this waterproofing system can be possible to protect water without the damage when vapor is going out from concrete and without air pockets because of the difference temperature inside and out. This system particularly consists of air bents and elastic waterproofing sheet considering the physical damage while water can cause purely physical damage. This system is one of the most efficient ways of waterproofing system without air pocket.
