Comet 700
Overlap welding with data recording in civil engineering
The geo-welding machine, COMET 700, is equipped with WIFI, GPS and the Leister Quality System (LQS) for quality documentation. It welds thick and thin geo-membranes reliably and efficiently to deliver ultimate user-satisfaction.
Comet 500
Reliable overlap welding of geomembranes in civil engineering
The COMET 500 hot-wedge welding machine is compact and easy to transport. It is particularly suitable for welding of thick and thin geomembranes made of PE, HDPE and LDPE in civil engineering.
Geostar G7
Civil engineering redefined: With the GEOSTAR G7 hot wedge welding machines for welding geomembranes.
The workhorse. Undefeated champion in its weight class (17.7 kg / 39 lbs.) With turbo motor and extra large hot wedge (130 x 50 mm) for maximum welding speeds.
Geostar G5
Civil engineering redefined: With the GEOSTAR hot wedge welding machines for welding geomembranes.
The super-fast and flexible all-rounder (with many accessories) welds practically every type of plastic while itself weighing only 16.4 kg / 36 lbs. Maximum reduced construction with cast aluminum frame and strong performance. With the G5, thinner materials can be welded just as securely as PVC with the steel wedge intended for that purpose.
Comet
Our smallest and most easy-to-handle welding machine COMET (only 7.5 kg), with integrated operating unit for civil engineering.

UNIROOF 700
The UNIROOF 700 is a compact, automatic welding machine suited to weld thermoplastic membranes (for example made of TPO, PVC, EVA, PIB and modified bitumen) on flat roofs up to approx. 500 sqm and slightly inclined roofs (inclination up to 30 degrees). It complements Leister's globally proven line of automatic roof welding machines. With the Leister Quality System (LQS) the important welding parameters (temperature, air volume and speed) are not only under control, but the welding quality is precisely documented.
Weldplast 605
Powerful hand extruder with high output
The powerful hand extruder, WELDPLAST 605, with LQS and 6 kg/h (13.2 lbs/hr) output is suitable for welding geomembranes made of PE and PP, even in large-scale civil engineering projects.
WELDPLAST S1
With the new WELDPLAST S1 compact extruder, you can achieve perfect seam quality with plate thicknesses of 4 to 12 mm (0.16 to 0.47 inch) and a maximum output power of 0.8 kg/h (1.76 lbs / hr) (PVC: up to 1.15 kg/h / 2.53 lbs / hr). The double-sided, twist-free wire intake can work with 3 to 4 mm (0.12 to 0.16 inch) wires. Integrated LED lighting plus the innovative operating panel are the perfect way to monitor the process of welding all typical kinds of materials.
