Wedge Welding Geomembranes, Liners & Heavier Heat-Weldable Materials
Geomembranes and liners were among the applications that established Novaweld’s wedge-welding experience. Today GT wedge-welding applications extend from handheld field work and repair to application-specific integrated BPR systems for membranes, liners, vinyls, and other heavier heat-weldable flexible materials.
BPR Wedge Welding for HDPE Geomembranes & Liners
Geomembranes and liners remain important wedge-welding applications. With BPR wedge welding, the material can remain supported while the welder moves along the seam, reducing unnecessary handling of large sheet materials. Current solutions include the genuinely handheld GT-100, while application-specific integrated BPR systems can be engineered for larger membrane, liner, and flexible-plastic applications.

GT-100 for Membranes, Field Work, Repair & Detail Welding

The GT-100 is the compact, operator-controlled member of the GT family. Its genuinely handheld architecture makes it practical where large membrane or liner assemblies are difficult to move, access is limited, or the operator needs to bring the wedge-welding system directly to the seam.
- No powered drive system is required for welding motion
- No drive-system jams and no downtime for clearing drive/feed jams
- Production, fabrication, field installation, repair, and patching
- Edges, overlap ends, straps, reinforcements, and detail work
- The GT-100 can also weld dissimilar flexible materials together when both materials can be heat welded
- GT-100 specifications list operating speed up to 60 feet per minute, depending on material and application
Heavier Plastics Can Call for Application-Specific GT Engineering
The GT-200 is specific to compatible nonwoven textile applications. For geomembranes, liners, vinyls, and other heavier heat-weldable plastics, other integrated GT/BPR systems can be engineered around the required material handling, seam geometry, tooling, controls, and production environment.
HDPE Geomembranes
Application-specific integrated BPR systems can be engineered around heavier membrane materials and the required field or production workflow.
Vinyls & Coated Materials
Different material weights, coatings, reinforcements, and seam geometries may call for a custom machine form rather than a standard field configuration.
Specialized Systems
Laser-guided tracking, split-wedge welding, pressure-verification channels, custom material handling, controls, and tooling can be considered when the application justifies integration.
HDPE, Vinyls, Liners & Other Flexible Plastics
A material label such as HDPE, polypropylene, vinyl, polyester, or nylon is only the starting point. Thickness, formulation, reinforcement, surface condition, layer structure, and required seam performance determine how the material behaves at the wedge.
