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.

In this study, the performance evaluation of waterproof sealant materials applied to the outer wall of PC apartment houses was conducted. The sealant for PC members must have resistance to movement, and since it is exposed to outside air, weather resistance and water resistance are required.

To overcome the limitation in relation to thermal insulator's selection and installation method that is suitable for exterior insulation and waterproof construction methods, a production basis of thermal insulators of which manufacturing knowhow is held by companies was ensured and future-oriented construction methods to adopt new materials were applied. Performance verification was conducted through performance and mock-up tests of thermal transmittance on the cross sections where the flexible insulators were applied based on the improved prototype and performance data were obtained. To overcome the biggest drawbacks (walking feeling and damage etc.) in the exterior insulation and waterproof construction method, inserting a protective layer between thermal insulator and water-proof layer was proposed, and polypropylene corrugated cardboards.

Waterproofing is a very important process in terms of durability of buildings. The materials used for waterproofing work to protect the concrete structure from external deterioration factors. In particular, the waterproofing materials applied to the exterior of the concrete structure have various problems due to changes in the external environment and variables in the construction process. The waterproof layer is repeatedly dried and shrunk according to changes in the external moisture environment, and the surface may be deteriorated due to exposure to long-term sunlight. In the case of the roof waterproofing in the structure, the waterproof layer which does not have a sufficient curing period shows much swelling and floating phenomenon. These defects, such as swelling and lifting, account for most of the defects that occur in the waterproof layer of the concrete slabs. Generally, it is difficult to expect the same level of performance as the initial state even if the waterproofing work is repaired when a defect occurs. Therefore, it is possible to reduce the defects of the waterproof layer such as swelling and lifting by forming a waterproof layer which can be integrated with the concrete surface by using a polyurethane type waterproofing material having a relatively low defective ratio compared to other waterproofing materials. So in this study, the basic properties of polyurethane waterproof sheet reinforced with non-woven fabric are investigated in order to understand field applicability.

Although the introduction of new materials and new construction methods and overseas materials has become more active due to the diversification of the construction market, the quality standards of waterproofing methods in Korea are insufficient. In particular, the quality control standard is applied to the KS F 2622:08 (Membrane Waterproofing layer performance test method), which is the existing standard, to prepare standards for quality control of waterproof materials, which is increased in Korea.

Concrete properties alone cannot provide satisfactory waterproof performance because concrete can generate cracks due to possible problems in design, construction and curing process, and various environmental factors. Therefore, concrete structures require installing waterproofing layers for concrete protection and various types of construction methods are currently being applied. The purpose of this study is to investigate the concrete strength changes when waterproofing admixtures are mixed into the concrete. The results of flexural strength testing confirmed that the initial strength of concrete specimens with the admixtures was lower than that of the concrete specimen without the admixture based on different curing periods.

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.

In 2017, 100 aftershocks with a magnitude of 2.0~3.0 and 615 minor earthquakes in Pohang in Korea caused the collapse and destruction of aggregate, tile, glass, and other structural components of multi-family houses constructed as finishing materials for buildings, causing damage to vehicles and casualties. Based on this factor, seismic design standards were established for non-structural elements of buildings that were applied only to past structures. Therefore, this study reinterpreted various vibration response spectra transmitted to waterproof layers as well as the definition and concept of the waterproof layer demand response spectrum derived by developing various vibration response test evaluation devices through a new testing apparatus.
