GEOMEMBRANE INSTALLATION SPECIFICATION
FOR HAND-HELD WEDGE WELDING
 

Hand-Held Wedge Welders are used to “wedge weld” or “seam weld” together two or more sheets of thermoplastic film or synthetic geomembrane materials.  Wedge welding can also be used to fold over an edge of material to form a pocket seam. Geomembrane materials that are easy to wedge weld include vinyl (PVC), high density polyethylene (HDPE), low density polyethylene (LDPE), polyethylene (PE), polypropylene (PP), polyurethane (PU), thermoplastic olefins (TPO), Hypalon (CSPE) as used in geomembrane liners and other industrial applications.  Material thicknesses best suited for hand-held wedge welding ranges from 10 mil (0.25mm) to 80 mil (2mm).  Hand-held wedge welding is typically used for small production applications, patchwork and maintenance of a landfill liner system or repair of just about any plastic sheet or film product.
