When construction of self-adhesion waterproof sheet, moisture conditions of concrete substrate is ignored. In this study, based on overdry condition, air dry condition, saturated surface-dry condition, wet condition states classified by the bond strength test was conducted. As a result, the state of air dry condition was good, saturated surface-dry and wet conditions of adhesion was reduced. It is confirm that concrete substrate wet conditions have effect on the bond strength of self-adhesion waterproofing sheet. Therefore, quality standard and comply with specification for surface moisture conditions should be strengthened, and under construction of self-adhesion waterproofing sheet, moisture conditions on surface of concrete should be strictly managed. |
