| Abstract |
The blister of waterproofing layer, less adhesiveness under a low temperature, peel off of sheet overlapping joint which were occurred from the existing waterproofing membrane methods, have been influenced the decrease of durability in buildings. For this reason, this study suggested the application of non-exposure waterproofing membrane which was laminated by HDPE-butyl rubber sheet with twist glass fiber mesh. And physical properties of it was evaluated to solve the problems as mentioned above. As a result of evaluation of physical properties, twist glass fiber mesh can disperse water vapor pressure which come up from concrete substrate. And it prevents the blister of a waterproofing layer and transformation of materials, So, it was confirmed that twist glass fiber mesh contribute to the rigid property of waterproofing layer. Moreover, an effective adhesiveness under a low temperature and watertightness of sheet's joints were improved by using of modified butyl rubber. Through the application of waterproofing membrane which was laminated by HDPE-butyl rubber with twist glass fiber mesh, existing problems of sheet membrane method will be solved. |
