Waterproofing materials applied in underground structures are commonly exposed to environmental factors such as rain water, vibration, structural movement. Particularly in the case of rain waters, the pollutants and chemical substances penetrate into the waterproofing layer surface and cause complex degradation. Approaching this problem with only conventional leakage preventative measures may prove difficulties in solving it. In this regard, 3 dimensional material evaluation methods (waterproofing system structure) should be employed over 2 dimensional methods, and a testing method that allows the simultaneous testing of various degradation conditions found in underground environments is necessary.
