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 westernizing 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.

In recent years, residential apartment building parking lots are built in underground spaces, and with conjunction to improve the environment of the urban area, artificial greeen roof systems are installed on the upper slabs. However, early plant growth are resulting in root penetration into concrete cracks and in turn into the waterproofing membranes, leading to degradation and damaging of the waterproofing system and structural durability. This issue highlights a problem of conventional maintenance system of concrete structures, and proposals for amendments follow. In this study, a waterproofing and root barrier construction design for the upper slabs of residential building underground parking lots is proposed, and motioned to be added into future construction specifications.

By comparing the survey and the actual situation at hand, the results showed that the lowest floor slab, wall construction joints, and floor expansion joints were the most prone to leakage. A waterproofing design method in underground parts of apartments is proposed to prevent leakage in underground of apartments. Further research is required for the establishment of this detailed design and construction guideline in regards to this study.

There is a problem to be solved for improvement of durability and safety for concrete When the waterproofing and anticorrosive work of main concrete are design, the material a of construction need to be correctly applied to appropriate circumstance conditions. Epoxy mostly been used for concrete water tank structure. Lately, lots of subjects on adaption res in mortar for waterproofing and anticorrosive are under discussion. Then, we attempt to approach by evaluating and comparing every capabilities with waterproofing materials in this experiment. Capability evaluation items include the bond age and curing conditions, the bond strength after accelerated weathering test and fret impact resistance, a mount of water, seepage quan Through the experiment analysis, we found that waterproofingtity, drinking water chemicals resistance. and anticorrosive resin mortar used with glass fiber cloth, inorgar material is dominantly superior to other waterproofing materials. According to this paper, we suggest the resin mortar as a new surface treatment material water tank structure.

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.

Waterproofing materials should be expected to last the life of the structure. An approximate life cycle cost should be to compare different materials based on initial and periodic repair / maintenance costs. Waterproofing applicators like materials that are easy to set up and clean up. The designer should choose a material that can be applied in almost all conditions. Design Professionals should specify independent inspection on critical jobs or in all cases where the budget permits. The basic causes of defection occurred during construction should be minimized.

It is socially increasing the need to maintenance of building's durability and management for building's safety. It has happened in waterproofing field, especially in case of water leakage in expansion joint and cracks, lacking basic design for waterproofing. After the completed of construction, there are many troubles something like this. Therefore it need for development to prevent from water leakage, using oakum and urethane in expansion joint and cracks as a method for waterproofing.

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.
