The PlastoSol Wedge Welding Machine is a fully automatic, self-propelled welding system that creates dual-track fusion welds with a test channel on geomembranes. This industry-standard machine is designed for high-speed, long seam welding on HDPE, PVC, PP, and other thermoplastic liners. The dual-track weld with air channel allows for non-destructive testing of every weld.

The industry-standard method for geomembrane seaming with built-in quality assurance
Dual-track (or double-track) wedge welding creates two parallel fusion welds with an unwelded air channel between them. This design is the industry standard for geomembrane installation because it allows for non-destructive testing of every seam.
The automated process for creating consistent, high-quality seams
Two sheets of geomembrane are overlapped (typically 75-100mm) and positioned in the machine's track guides.
The electrically heated wedge slides between the sheets, heating both surfaces to fusion temperature simultaneously.
Immediately after heating, pressure rollers compress the softened materials together, creating the fusion bond.
The machine automatically travels along the seam at a controlled speed, creating consistent welds continuously.
Advanced features that make our Wedge Welder the professional's choice
Self-propelled operation with automatic speed and temperature regulation for consistent welds.
Creates two parallel welds with air channel for 100% non-destructive testing capability.
Welding speeds up to 5 meters per minute for maximum productivity on large projects.
LCD display with precise digital controls for temperature, speed, and pressure settings.
Built-in data logger records welding parameters for quality documentation and traceability.
Easily adjustable overlap width to accommodate different material thicknesses and specifications.
Simple wedge replacement and cleaning procedures minimize downtime and maintenance costs.
Heavy-duty construction designed to withstand harsh field conditions and continuous operation.
