Every machine, consumable and test instrument used to weld and prove a thermoplastic liner seam, supplied from stock in Dubai and shipped worldwide.
Three welding processes cover a geomembrane installation, and a working crew carries all three. The hot wedge welder makes the long production seams. The hand extruder handles patches, penetrations and detail. The hot air gun tacks panels in position and welds thin material. Alongside them sit the consumables and the test equipment that turn finished welds into documented ones.
Our own-brand machines and the consumables that go with them. Real manufacturer specifications on every page.
The IZ-900 automatic hot wedge welder produces the long production seams. Self-propelled, with dual digital control of temperature and speed, and a dual track weld that leaves a sealed channel for air pressure testing.
The hand extrusion welder used for patches, repairs, pipe penetrations and every corner a wedge welder cannot reach. Feeds 3 mm or 4 mm HDPE rod and lays a fillet bead over the sheet edge.
The IZ-1600. For tacking liner in position, welding PVC and tarpaulin, and preheating before extrusion work. 1600 W, 180 L/min, 1.05 kg. The cheapest and most used item on a lining crew's plant list.
4 mm HDPE welding rod in black, blue, white and green, plus LDPE, PP and PVC. Using rod of the wrong grade, or the wrong colour on an exposed liner, is a common reason a repair fails.
Air pressure test kit with a dual scale psi and kPa gauge, hose and insertion needle for dual track seams. Vacuum boxes, spark testers and tensiometers to order. The kit that turns a finished weld into a documented one.
Heating elements, carbon brushes, welding boots, nozzles, fuses and drive parts for the IZ-900, IZ-620 and IZ-1600. Held in Dubai so a worn part does not stand a crew down for weeks.
Leister group machines supplied beside our own IZ range. Brand-specified projects and 0.8 mm liner go Weldy; price-led purchases on 1.0 mm and above go IZ. How to choose between them.
Wedge welder rated from 0.8 mm HDPE, the thin liner machine. Copper wedge, 0 to 8.5 m/min, hard transport box.
The extruder Weldy rate highest for geomembrane. Long barrel for standing work, ships with the UBL30 overlap shoe.
Compact extruder for tanks, pools, ducts and fabrication. 360 degree shoe, side handle, spare element in the kit.
1600 W hot air gun with a ceramic element and 700 degree ceiling. Three kit options; the overlap kit is the one for liner.
Liner, machines and consumables ship on one consignment. See the geomembrane range.
Most geomembrane specifications name the process explicitly. Primary seams are almost always required to be dual track hot wedge welds, tested by air pressure to ASTM D5820, because that is the only field method that proves an entire seam non-destructively. Extrusion welding is permitted for patches, penetrations, cap strips and repairs, tested by vacuum box to ASTM D5641. Hot air is generally allowed for tacking only.
If you are buying equipment to satisfy a specification rather than for general use, send us the relevant clauses. It is common for a contractor to buy a machine that cannot produce the seam the engineer will accept. Our selection guide works through the decision in more detail, and the liner specification page lists the seam strength values each gauge must reach.
For the wider context, see our geomembrane welding machine dealer page.
Send the liner thickness, the seam length and the specification clause. We will tell you what the work requires before you spend anything.
