LST800 Geomembrane Hot Wedge Welding Machine

The LST800 Geomembrane Hot Wedge Welding Machine is a compact and efficient thermoplastic welding solution designed for joining geomembranes, waterproof membranes, and other synthetic liner materials. Ideal for landfills, reservoirs, mining operations, aquaculture projects, tunnels, environmental protection systems, and civil engineering applications, this machine delivers strong, consistent welds with excellent seam integrity.

Powered by an 800W heating system, the LST800 utilizes advanced hot wedge welding technology to create durable double-track welds with a central air channel for seam testing and quality verification. The adjustable temperature range of 50°C to 450°C allows operators to optimize welding performance for various material types and site conditions.

With a variable welding speed of 0.5 to 5 metres per minute, the machine provides flexibility for both small and large-scale installation projects. It is suitable for welding geomembrane materials with thicknesses ranging from 0.2 mm to 1.5 mm, ensuring reliable performance across a wide variety of waterproofing and containment applications.

Weighing only 5 kg, the LST800 is lightweight, portable, and easy to operate, making it an ideal choice for field installations where mobility and efficiency are essential.
