Welding of plastic geomembranes for ponds and swimming pools
Flexible and safe

VARIMAT V2, TRIAC AT

Artificial lakes, swimming ponds, and swimming pools are all the rage! In order to ensure the safety of the sealing system, reliable tools are needed, which are not only able to weld perfectly, but can also work across large areas economically and ergonomically. Leister offers the right welding machines for all areas and materials. The VARIMAT V2 is particularly well suited to the overlap welding of large areas with an even surface, as are often encountered in swimming pool refurbishment projects. The flexible UNIROOF E, which is also used for roof covering systems, is appropriate for smaller areas. For uneven surfaces such as those found in artificial lakes, swimming ponds or biotopes, the answer is the hot-wedge machines otherwise used in civil engineering: The small, easy to handle COMET and TWINNY tools adapt to the surface topography perfectly and weld the plastic geomembranes safely, making them absolutely leaktight. Leister offers a wide range of hand welding tools and matching accessories, such as nozzles or the legendary Leister pressure roller, for welding connections and details.
