Welcome to a new dimension in civil engineering with Leister‘s new „Faster, Lighter, Smarter Wedge“! The advent of the GEOSTAR for welding geomembranes marks the appearance of a hot wedge welding machine perfected for civil engineering that redefines state-of-the-art technology.

The compact, cast aluminum frame construction offers sporty maximum power for the hardest applications: With heating capacity/heating power of up to 2500 Watts, peak welding speeds of up to 12 m/min (39 ft/min) and height-adjustable chassis, the GEOSTAR can handle any terrain without difficulty.

The digital operating unit (“eDrive”) with integrated display permits permanent monitoring of all the key weld parameters (heat, speed, pressure and voltage) during work process.

This sleek new design makes field servicing a cinch – wedge can be removed and replaced in under a minute. Additional features include easy loading of material, natural flow of material through the machine, integrated clamping grip engagement, innovative ergonomics that allow one-hand operation and three different parking and maintenance positions.
