Abstract

For successful waterproofing construction, it is very important to secure construction quality as well as material performance of waterproofing materials used in construction. Due to the long-term cost reduction policy following the economic downturn in the construction market, most construction companies are using general low-priced waterproof materials rather than high-quality waterproof materials without clear quality control standards. Without clear education on construction, construction is being carried out with meaning only on construction activities. In addition, the waterproofing method applied in combination is a situation where water leakage occurs due to waterproofing failure due to insufficient construction quality because the construction method is complicated. Therefore, it is necessary to review the quality control measures(design, materials, construction) for successful waterproofing work and improve problems that are derived so that stable waterproofing work can be done. In order to expect the leakage prevention effect of a building, first, it is required to select appropriate materials for each part of the building and environment in the design stage, and the selected materials must satisfy all items of the Korean Industrial Standard(KS). Second, to secure the quality of waterproofing construction, sincere construction by workers is required. In this paper, we tried to describe "review of waterproof design", "constructor education", "site inspection", and "criticism(correction/supplementation)" as quality control measures after material selection.

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.
