Civil engineering applications
Safe and ergonomic welding of plastic membranes with Leister
In civil engineering, tunneling, and disposal applications, the quality of the sealing system is the top priority. Any leaks can have fatal consequences. Therefore, it is incredibly important that the processing quality fulfills extremely stringent requirements. Not only the material itself and the processor are responsible for this – in large part, so is the tool used to carry out the work. Leister tools not only facilitate incredibly precise welding, they also stand out from the crowd thanks to their ergonomics. They can be relied on, no matter where in the world they are used.
Automatic Welders
The new UNIROOF AT automatic roof welder solves every problem. Close to the edge and service-friendly. Reliable and no modifications necessary: Close edge welding right out of the box.
This lightweight tool TWINNY S is optimized for overhead welding and is ideal for thin materials used in civil engineering and tunnel construction.
TWINNY T USB makes data storage and is excellent for welding PVC and other thin or soft membranes.
The TWINNY T is available in two performance classes: TWINNY T7 and T5. Both automatic welders are ideal for welding thick and thin geomembranes.

The small powerhouse, COMET, is specially designed for the demands of landfill sites, mines and tunnels.
COMET USB's memory system is designed for use on construction sites, because this compact, hot-wedge welding machine records all relevant welding parameters.
The workhorse. The undefeated champion in its weight class (17.7 kg / 39 lbs.) With extra amounts of driving force and large welding wedge (130 x 50 mm).

Extrusion welders
Extrusion welding redefined - the brilliantly maneuverable Fusion 1 one-hand extruder with reduced design for more flexibility when welding with double-sided wire intake, automatically controlled air temperature, LED light, practical suspension device and removable handle.
The FUSION 2 convinces with its ergonomic design. The simple operation and first-class welding quality have helped it to become the breakthrough product.
The WELDPLAST S2 is a compact, ergonomically designed workhorse. The handy size extrurusion welder puts out two kilograms per hour without difficulty.
The WELSDPLAST S2 PVC has integrated corrosion protection and has been especially designed to satisfy the high requirements of PVC extrusion welding.
The WELDPLAST S2 TPO is a compact, ergonomically designed workhorse. The handy-sized extrusion welder puts out two kg / 4.4 lbs. of extrudate per hour and can even weld TPO materials without difficulty.
The WELDPLAST S4 is the first extrusion welder of its kind with brushless, maintenance-free motor for generating preheated air. Output of up to 4 kg / 8.8 lbs. of extrudate per hour is made possible thanks to the S4's powerful drive system.
WELDPLAST S6 is the world's highest rated handheld extrusion welder. With an output of 6 kg / 13.2 lbs per hour, the S6 surprisingly maneuverable.
The somewhat shorter FUSION 3C provides an astounding output volume of up to 3.6 kilograms (8 lbs.) per hour.
Hot air hand tools
The TRIAC AT is an intelligent hot-air hand tool for welding and shrinking plastics that is suitable for on-site use.
This is why it is lighter, quieter and more durable than any other hot-air hand tool. Discover its unbeatable advantages – SOLANO AT.
