Fusion welding

The welders heat and melt the surface of the geomembrane and then compress the material between two rollers

Extrusion fillet

Extrusion fillet welding consists of extruding a bead of molten resin along the edge of a panel lapped on top of another panel.

Seam Testing By Air Pessure

The wedge welded seam process creates a hollow channel approximately 3/8 of an inch between the two weld seal.   The sealed channel is inflated to a predetermined air pressure and is observed over a period of time for stability.

Pipe Boot Attachment

Pipe boots can be fabricated from the geomembrane.  Fabrication and attachment of the boot to the geomembrane should be done with the extrusion welding process.
