... assurance/quality control test instead of destructive sampling and testing of PVC geomembrane seams (Thomas and Stark 2003). Therefore it is necessary to develop a relationship between sheet temperature, burst pressure and peel strength. This relationship allows field personnel to determine the air channel...

... 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...

... control Seams Thermal welding The need to have field seams that can be checked quickly with measurable results has caused geosynthetic engineers and quality assurance/quality control (QA/QC) technicians not to prefer field chemical seams for polyvinyl chloride (PVC) geomembranes. In recent years...
