How to choose a geomembrane welding machine
Which of the three processes your specification requires, what to compare between machines, and the mistakes that cost the most.
Guides and technical resources
How the three welding processes actually work, how to set them for the liner in front of you, how seams get tested, and what to do when a weld fails.
All guides
Wedge versus extrusion welding
Two processes, two purposes. How each joins the sheet, why one is testable by air and the other is not, and where each belongs.
Temperature and speed settings by thickness
Starting parameters for every liner gauge, why they change with the weather, and why trial welds are not optional.
Geomembrane seam testing methods
Air pressure, vacuum box, peel and shear. What each proves, what each misses, and why failure mode matters more than the number.
Seam defects and their causes
Cold welds, burn through, lifting beads and porosity. What each looks like, what caused it, and what to change.
Operating an extrusion welder
Preparation, purging, preheat and bead technique, in the order they happen, with the errors that cause most peel failures.
Types of plastic welding machines
Hot wedge, extrusion and hot air, plus the variants within each, and why MIG and TIG have nothing to do with liner work.
What a geomembrane is used for
The applications that drive liner demand, the materials used, and why the seam rather than the sheet decides whether containment works.
Mil to mm thickness conversion
60 mil is 1.5 mm. Why two measurement systems exist, and the ordering mistakes that follow when they get mixed up. With a converter.
Landfill liner and CQA requirements
The strictest seam regime in lining work. Trial welds, sampling frequency, testing and the paperwork that decides whether a cell is accepted.
Small and portable machines
When compact kit is the right answer, what you give up, and the jobs where a small machine genuinely beats a large one.
Supplier, manufacturer or factory?
What the words actually mean in this trade, who carries which risk, and how to tell what you are dealing with.

A working list of sheet suppliers, pool specialists and price guides across Dubai, Sharjah and Abu Dhabi, with the checks to run before ordering.
All of this is backed by the machine range we stock and export from Dubai.
Question the guides do not answer?
Send the specification clause, the liner grade or a photograph of the seam. We would rather answer a technical question than sell you the wrong machine.
