The goal of waterproofing materials and construction method used for underground structure can be attained only when construction is done perfectly free of laitance, moisture and foreign substances on concrete surface. However, construction engineers agree that it is difficult to perfectly carry out such work in practice and realization of perfect waterproofing for underground structures is impossible in reality. Therefore, this study is to examine and explore waterproofing materials and construction method completely meeting environmental impacts that underground structures receive and thereby suggest waterproofing technology applicable to underground structures, in order to prevent problems caused by leakage for underground structures.

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.

This Waterproofing Material which mainly consisted of 2 components of waste tire chip powder and waste glass powder. This Study is abut development of waterproofing Material, There is not tried in domestic. The most Motive of this Study wishes to recycle resources and get the economic performance for waterproofing Material The result of this Study is as followings. (1) Dense waterproofing floor is formed between waste tire chip by Coupling Agent(the most effective method to encourage adhesive strength and raise cohesion of material by combination.) (2) Expected to bring effect to shorten construction period at spot application potentially space-time in moisture aspect. Also, shortening effect of construction period and spot work are considered to be gone efficiently selecting pre-mix construction method. (3) This development Waterproofing material has elasticity that nature side compatibility of cement ingredient and plastic Emulsion have when utilize and constructs waite resources (being waste tire chip and waste glass powdered).

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.

This technology is able to construct with hardening UREPALT adhesives and TPO URE-Sheet simultaneously using automatic equipments. the benefit of this construction method is that The layer of waterproofing is uniform and defect of construction would be reduced because of no construction joints between UREPALT adhesives and TPO URE-Sheet. Furthermore, this new method could accomplish shortening of construction period, quality control and saving of labor costs. Also the non-exposure waterproofing method would be protected from fire and safe for workers without using a torch.

A heat and room temperature construction method of asphalt have been mainly applying to rooftop waterproofing in concrete structure, and the rest construction method are sheet, membrane and mortar waterproofing construction method. In particular, joint method in sheet waterproof method is as overlap joint which on being reinforced with fiber and tape, have been applying for job site to mechanical fix using protection disk and anchorage and metal ironwork on the end of sheet. These construction method cause cutting off joint of sheet as behavior of structure according to repairs of sheet itself and thermal conduct, outdoor air environment. In conclusion, we analyzed and examined the application of various sheets and piece ashes about superior 'I' joint which divide from one and the other sheet and progressed about joint construction method of fixing method for overlap.

This paper intends to analyze the roles of regulations and certifications within the construction market that affect the effective recycling and application methods of construction waterproofing industries. Certifications, eco-labels, green certification patents, and new excellent technologies obtained in construction waterproofing industries are studied. In accordance to the study results, it was determined that, a total of 38 items obtained eco-labels with effective recycling as the theme, 10 items with green certifications, and 8 items with New Excellent Technologies.

There is a problem to be solved for improvement of durability and safety supervision. When you do the waterproofing and anticorrosive work of main concrete from the design stage, the material and method of construction need to be correctly applied to appropriate circumstance conditions. Epoxy have mostly been used for concrete water tank structure. Lately, lots of subjects on adaption of polyurea resin waterproofing and anticorrosive are under discussion. Then, we attempt to approach by evaluating and comparing every capabilities with another waterproofs in this study. Performance evaluation items include the adherence performance, the imprint of seal performance, temperature dependence performance, promotion weatherizing ability, inner chemical performance, drinking water eruptive performance. Through the experiment analysis, we found that the polyurea resin waterproofing membrane is dominantly superior to other waterproofs. According to this study, we suggest the polyurea resin waterproofing membrane as a new waterproofing material for concrete structure.
