.... This paper focuses on non-destructive air channel testing of dual-track seams. The thermally welded 0.75 mm thick PVC geomembrane seams presented by Stark et al. (2004) and used herein to extend the correlation were evaluated by the standard peel test at 50 mm/min at 22.8°C (ASTM D 6392...

... constructed by EPI at low-temperature conditions are also used. A hot air welder was used to thermally weld the 0.75 mm-thick PVC geomembranes. The sheet temperatures range from –3.9°C to 2.8°C during thermal welding. Geosynthetics PVC geomembrane Air channel testing Seams Quality assurance Quality...

...R. W. Thomas; T. D. Stark; H. Choi Polyvinyl chloride (PVC) possesses excellent thermal welding characteristics, such as a wide thermal seaming range and the absence of a need for surface preparation such as grinding. The focus of this study was to utilise these welding characteristics to develop...
