How To Weld Dam Liners


Grekkon Limited trains technicians and farmers on how to weld dam liners during installation or pond liner repairs. Welding is for every dam liner who’s width is beyond 8M to fit the water pan or tank. This is because our dam liner rolls are 8M wide. It is irrespective of the fish pond liner’s thickness or material type. Our dam liners thicknesses are; 0.5mm, 0.75mm, and 1mm, and the material is either a high density polyethylene  (HDPE) geomembrane, or a poly-vinyl chloride (PVC) type. Both materials have anti-UV treatment to withstand solar degradation in UV intense tropical locations

Welding structures the pond liner to the water pan’s or tank’s shape, so as to hold water. The welded joints must be leak free for the dam liner to work effectively in the tank or water pan. Lined water pans are popular as water storage units for agricultural field crops irrigation in a country that has just one or two rany seasons

How To Weld Dam Liners

  1. Factory welding. Depending on the dam liner size, weld it whole or partially in the factory. The weight and volume of the welded material must be easily portable on site.  The latter factor guides on how much of the dam liner material will be put together in the factory
  2. Site  or field welding. This is done on site at the point of dam liner installation. It is the joining together of the partially welded dam liner pieces from the factory. Site welding is done when the entire dam liner could not be wholly put together in the factory. This is as a result of weight or bulkiness, which limits lifting and transportation of the bulky and heavy material. The weight size of the protable material depends on the thickness of the dam liner. The thicker it is, the less it is
  3. A wedge welding machine or a heat gun/ heat blower is the equipment that does dam liner welding. A wedge machine is what does it in the factory. The heat gun is highly portable, and so is best for field joinery

Dam liner welding involves melting the liner material under high temperture at the point of joining them. Once melted, the 2 layers are laid one over the other and as they harden, become one unit

Both equipment run on electric power. In off grid electricity locations, Grekkon Limited provides a generator to power the heat gun or wedge welding machine
