Abstract

A sprayable waterproofing membrane which is composed of polymer-based material is relatively easy to install due to its construction method comparing with sheet-type membranes. And a sprayable waterproofing membrane has very similar material composition to the TSL which is for a permanent support. In this study, material composition of the sprayable waterproofing membrane was changed to enhance structural properties of membrane while maintaining waterproofing performance. In order to compare with a previous research for the TSL, series of tests were performed according to the performance criteria used for permanent support material (TSL) by EFNARC (2008). From the test result, the structural performance of the sprayable waterproofing membrane considered in this study showed a performance that could be used as a permanent support material.

차수용 박층 멤브레인은 폴리머로 구성된 재료로 기존 방수포(sheet membrane)를 대체할 수 있는 뿜어 붙이는 방식의 차수 재료이다. 시공에 있어서 뿜어 붙이는 방식을 사용하기 때문에 타설이 용이하고 상대적으로 높은 부착성능을 보인다. 차수용 박층 멤브레인의 배합은 영구 지보재로 쓰이는 TSL(Thin Spray-on Liner)와 매우 유사한 구성을 갖으나 적용 목적에 따라 차수와 지보재로 구분하고 있다. 본 연구에서는 차수용 박층 멤브레인의 차수 성능을 확보한 상태에서 구조적인 성능을 보강할 수 있도록 배합비를 조절하였다. 이를 검토하기 위해, 영구 지보재용 멤브레인 재료에 사용되는 성능 기준에 따라 시험을 수행하고 결과를 검토하였다. 시험결과 본 연구에서 고려한 차수용 박층 멤브레인의 구조적 성능은 영구 지보재로도 사용이 가능한 정도의 성능을 보였다.
