The processes that have been approved for field seaming and repairing are extrusion welding and fusion welding. All welding equipment is fitted with accurate temperature monitoring devices to ensure the proper measurement of the applicable fusion welding wedge temperature or the extrusion barrel temperature.

Double hot wedge weld
This is a thermal technique that melts the two opposing geomembrane surfaces together by running a hot metal wedge or knife between them.
Extrusion fillet weld
This seaming technique involves extruding molten polyethylene at the overlapping edge of geomembranes to form a continuous bond.
Testing Method
To ensure quality, longevity and a product that we can confidently hand over to the client, all seams are tested before general seaming operations may proceed via the peel test and air pressure test.
