Research has begun to change the waterproofing design of domestic underground structure parts from the current negative-side waterproof design to the positive-side waterproof design. For this, active review from the design stage to prevent the ingress of external ground water into the waterproofing measures of the underground of apartment buildings is needed. Therefore, in this study, proper waterproofing method for the major leaks identified in the previous studies and a waterproofing method for the waterproof design of the underground floor and the outer wall is proposed. It is hoped that a follow-up study, such as a review of field applicability, for the proposed methods will provide an alternative to secure leakage stability in waterproof design.

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.

현재 대형 빌딩이나 공동주택에 건설되는 지하구조물은 건조수축, 시공이음, 폼타이부 등에서 콘크리트 균열로 인한 누수가 많이 발생되고 있다. 누수가 발생하게 되면 구조물의 지하공간은 결로, 곰팡이 등이 발생되어 지하 환경을 악화시키고 구조물의 콘크리트로 흡수되면 철근의 부식 등을 유발하여 구조물의 안전을 위협한다. 이는 지하구조물의 사용과정에서 장기적인 쾌적성과 구조물에 안전성이 고려되지 않은 설계와 시공의 결과이며 누수 하자에 대하여 유도배수처리로 대응하기 때문에 근본적인 누수보수가 이루어지지 않아 지하구조물은 항시 누수를 허용하고 있는 실정이다. 따라서 본 연구에서는 지하에 적용되는 방수공법을 내방수와 외방수로 분류하고 이를 바탕으로 지하구조물과 유사한 간이시험체를 제작하였으며, 결로가 많이 발생되는 동절기의 온도조건을 기준으로 지하환경의 방수공법별 습도변화량을 분석할 것이다.

The waterproofing in slab and wall of underground structure, have a couple of construction methods which are inside waterproofing methods for inner surface, and outside waterproofing methods for out wall and slab surface waterproofing. In resent years, however, it has been adapted the inside waterproofing construction method, as increasing of construction expenses cost and low workability and technology, nevertheless, outside waterproofing has set a most high value construction method. In inside waterproofing construction method, it is difficult to repair and assure durability and safety for concrete which has direct water-press. So, It is necessary for adopt the outside waterproofing method.

Waterproofing techniques used in underground structures do not reflect material and construction environments, but rely only on material properties, which inevitably lead to their limits in durable life. In particular, the government intends to investigate the current underground water treatment method and analyze the problems in order to prevent serious corrosion and aging of structures caused by underground water leaks and poor construction.

Recently, various maintenance materials and construction methods have been developed to secure the sustainable performance of structures. However, waterproofing of underground structures where groundwater infiltration is present is very difficult. In particular, the location of underground structures such as subways is very deep, and it is difficult to apply waterproof materials and construction methods in the case of structures accompanied by vibration. Therefore, we intend to study materials and methods for waterproofing leakage resistance in special environments such as underground structures.

Existing studies highlights the problems about the negative-side waterproofing design of apartment complex underground structures. This study suggests the alternatives for waterproof design construction details of as a solution, and a review on the applicability of this new construction design details through a mock-up construction is provided.

The accidents of oil leakage is increasing in the Underground Concrete structures for Oil Storege. In the result, the waterproofing in the underground structures is melt down and cannot fulfil its Performance. This study shows an experimental study in the effects of the oil leakage to on the performance of Waterproofing Materials. In order to investigate the actual condition and the problems, a comparative analyses were conducted considering the various types of leakage. Utilizing the obtained results at the basic data for test methods and the standard of quality, we intended to propose a strategy to develop an innovated waterproofing Materials and improve the clean environment of underground structures.

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 purpose of this study was to contemplate the effectual waterproofing materials and construction methods for the restoration of underground infrastructures using precast arches(PC-Arch). Until now, there were no proper waterproofing guidelines for waterproofing precast arch tunnel when restoring cultural heritage or building underground infrastructures for noise control. Asphalt membrane sheets were commonly used, but the efficacy of waterproofing done on the precast segment was vulnerable. This study aims to examine the Synthetic Rubber Polymerised Gel(SRPG) proposed in ISO TR 16475, a guideline for the repair of water-leakages, and to demonstrate field applicability based on the waterproofing solution used on the road improvement project in front of Changgyeonggung Palace in Yulgok-ro, Seoul, Republic of Korea.
