Welding of geomembranes for reservoirs and fish farms

Leaktightness is an extremely high priority when it comes to sealing systems for distribution reservoirs and fish farm tanks. For the most part, such sealing systems consist of HD-PE, PP, PVC or TPO material. Welding must ensure that the material remains totally leaktight in the long term. Reliable tools, but ones which also enable welding to be carried out quickly and, therefore, economically, are needed here to safeguard the safety of the sealing system. The small, easy to handle COMET and TWINNY tools adapt to the surface topography perfectly and weld the plastic geomembranes safely, making them leaktight for the long term. Vertical and horizontal work can be performed on walls too with the lightweight and flexible UNIDRIVE 500 semi-automatic welding machine. Leister offers a wide range of hand extruders and hand welding tools, together with matching accessories, for welding connections and details.
