Abstract

In this study, an evaluation was conducted for a total of 16 conditions to suggest an appropriate construction method for the construction joint of polyurea waterproofing membrane coating. It was analyzed that the longer the construction time difference, the higher the rate of water leaks through joints, and it was confirmed that water leaks could be prevented through primer construction. In addition, since the surface of polyurea exposed outdoors for a long period of time is deteriorated and weakened, it was analyzed that polishing the area increases surface damage and affects the formation of the interface. During maintenance construction, it would be desirable to apply a primer before construction, and it is believed that using the same urea-based material will ensure waterproofing stability.

본 연구에서는 폴리우레아 도막방수재의 시공 시차별 분석과 열화면에 대한 유지관리 시공 타입별 분석을 통해 시공 이음부위의 적정 시공 방안을 제시하고자 전체 16가지 조건을 대상으로 시공 이음부위에 대한 평가를 진행하였다. 결과 분석을 통해 시공시차가 길어지면 길어질수록 이음부를 통한 누수발생률은 증가하는 것으로 분석되었고, 프라이머 시공을 통해 누수 예방이 가능한 것으로 확인되었다. 또한 장시간 옥외 노출된 폴리우레아는 표면이 열화되어 약해진 상태이기 때문에 해당 부위를 연마할 경우 표면손상이 확대되어 계면 형성에 영향을 미치는 것으로 분석되어, 유지관리 시공 시에는 프라이머를 도포하고 시공하는 것이 바람직하겠으며, 동일한 우레아 계열의 재료를 시공하는 것이 방수 안정성을 확보할 수 있을 것으로 판단된다.
