HDPE geomembranes are used worldwide as sealing elements for water retention and in environmental protection. To achieve a fully impervious layer, single geomembrane panels are joined by the methods of hot wedge welding or extrusion welding.
These welding methods demand specific machinery and specific knowledge of the operators on external factors that have an impact on the weld quality. While the welding work itself is highly specialised and will be carried out by expert plastic welders, some considerations are already to be made when specifying and scheduling welding works.
The upcoming webinar will show some of the key factors that have an influence on the weld quality. It shall be an aide for designers and contractors of the potentials and limitations (e.g. weather) of geomembrane welding.
