Geomembrane Wedge Welder

Geomembrane Wedge Welder – is a specialized tool used in the construction and civil engineering industries to weld or fuse together sheets of geomembrane material. Geomembranes are synthetic liners used to control fluid movement in various applications, such as landfill liners, pond liners, and containment systems.

How It Works:

1) Welding Process: The wedge welder uses heat generated by an electrically heated wedge or a hot air nozzle. The heat melts the surfaces of two overlapping sheets of geomembrane. When the material cools, the rollers press the melted surfaces together while the wedge or nozzle advances along the seam, producing a strong, waterproof weld.

2) Adjustable Parameters: The machine allows the operator to adjust parameters like temperature, speed, and pressure, which are crucial for achieving a proper weld depending on the type and thickness of the geomembrane material.

Wedge welders are essential for ensuring the integrity of geomembrane installations, providing a long-lasting and reliable seal in critical applications.

Applications

Landfills
To seal waste from the environment.
Ponds and Reservoirs
To prevent water seepage.
Tunnels
To protect against water ingress.
Mining Operations
For containment of chemicals and waste products.

Types of Welders:

Single Wedge Welders: Typically used for thinner geomembranes.
Dual Wedge Welders: Often used for thicker materials or for applications requiring higher strength welds.
