Abstract

This paper studies the leakage situation of domestic residential building underground parking lots and main leakage areas. 18 complexes were studied and the results showed that 80% of buildings with exterior waterproofing had no leakage, but all buildings with interior waterproofing had leakage. According to a survey among professionals, water leakage problems are considered to be severe in underground parking lots and a preventative measure is required by the government. 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. Based on the results, further study to develop a design manual for the appropriate prevention of leakage is deemed necessary.

본 연구에서는 현재 국내 공동주택 지하주차장의 누수실태를 파악하고, 실제 누수가 가장 빈빈하게 발생되고 있는 주요 누수부위를 파악하여 향후 공동주택 지하부위 누수 예방을 위한 기초자료로 기여하고자 하였다. 18개 단지를 대상으로 누수실태 조사를 진행한 결과 외방수를 적용한 전체 80% 단지에서 누수가 발생되지 않았으나, 내방수를 적용한 단지에서는 전부 누수가 발생되고 있었다. 방수와 관련된 건설분야에 종사하는 전문가를 대상으로 진행한 설문조사 결과, 현재 공동주택 지하주차장의 누수 문제는 심각한 수준으로써, 누수에 대한 대책이 요구되며, 무엇보다 정책적 기준 마련이 중요하다고 판단하고 있다. 누수 실태조사 결과와 설문조사 결과를 비교, 분석한 결과 누수가 빈번한 주요 구조부위는 외벽과 최하층 바닥 슬래브이며, 누수 취약부위는 벽체 시공 이음부와 바닥 신축줄눈으로 판단할 수 있었다. 향후 해당부위의 누수 예방을 위한 방수 설계지침 및 시공시방 등에 대한 후속적인 연구가 필요하겠다.
