A Study of the Field Test Method for the Adhesive Performance Evaluation of Self-Adhesive Waterproofing Sheets

In the field of waterproofing concrete structures, use self-adhesive sheets has become a popular technique for ensuring long-term performance. One important characteristic such sheet materials is maintaining their stable adhesion strength over an extended period. Adhesion testing serves as crucial method assessing However, standardized test method, including equipment and criteria, directly measuring applied to onsite walls not yet been established. Therefore, reliance on laboratory evaluation results only option thus far. this study, field-applicable measurement device was developed in effort provide quality control demonstrate validity utilizing device. The designed based principle peel-out compliance with requirements outlined KS F 4934, where specimen backing plate can slide into 1:1 ratio at same distance rise tension jig when raised 45° angle. By device, values were compared those obtained using universal machine (Salem, MA, USA) (UTM) specimens. Comparative analysis yielded that standard deviation varied tested materials, overall UTM measurements 0.17, while it 0.18 portable equipment. comparison indicated limited scope specifications, possibility wider usage be made possible more data studies.
