A study on the characteristic of adhesion on the low temperature concrete of self adhesive waterproofing sheet using interface leakage test.

계면 누수를 통한 자착형 방수시트의 저온 부착 특성에 관한 연구

Recently, waterproof construction used to self adhesive waterproofing sheet in the actual field in winter for reduce cost and term. However self adhesive waterproofing sheet's quality is declined in low temperature condition. So, this study was to confirm on the low temperature condition of concrete substrate effecting the adhesion of self adhesion waterproofing sheet using interface leakage test. As a result of this study, self adhesion waterproofing sheet must not be used at temperature below 5℃. Also, adhesion between waterproofing sheet and concrete is declined in low temperature.
