Geomembrane sheets

The main reason for using geomembrane sheets in insulating a range against water penetration into the soil. The main properties of polyethylene are its high durability (between 50 and 100 years) and excellent corrosion resistance against solvents and even acidic environments. These intrinsic properties of polyethylene, along with the design of a special formulation in Farnam Baspar Company to resist the environmental conditions of weather and sunlight, help the geomembrane sheets made in this company to have a very high quality and durability. The main application of Farnam Baspar geomembrane sheets is in the construction of agricultural water storage ponds, insulation of concrete tanks, fish ponds, insulation of buildings and tunnels, and prevention of infiltration of effluents in landfills.

   Farnam Baspar Company is the only company in Iran that produces these sheets up to 7 meters wide for easier installation and less sewing line on the surface of the pool or tank. This (production of very high width sheets) directly affects the quality of the entire coated surface (On large surfaces, to extent the sewing lines are smaller, the number of weak and vulnerable points will decrease). The additives used in this sheet lead to its highly resistant to both weather and sunlight conditions and to decomposing bacteria in the soil. In landfills, it is important not to infiltrate the subsoil before the decomposition of environmentally hazardous materials and effluents is completed. This company’s geomembrane product with corrosive additives of the sheet have resisted corrosion and perforation against various acidic, alkaline or chemical conditions in the effluents and it maintains them until the end of decomposition and elimination of environmental hazards of the effluents.

   One of the most important uses of geomembrane sheet is its utilization in the process of extracting precious metals from its ore (Heap Leaching). For this purpose, after installing the geomembrane sheet in the pre-prepared place, the extracted ore is spread on the sheet and while spraying sulfuric acid according the schedule, it dissolves existing metals and is transported to predetermined channels by geomembranes.

   This product is produced and supplied in a width of 7 meters (the largest width in our country and the most common in the world) with a thickness of 0.8 to 3 mm and according to the indicators GRI-GM13 standard as a universally accepted standard for this product, And the size of the mentioned indicators in the laboratory equipped and located in the factory is carefully controlled and then provided to the consumption network. Although the national consumption is lower, but for the annual production capacity of 7 million square meters has been invested and with a history of 10 years of activity, millions of square meters of it has been used in various industries, including power plants to cover evaporation ponds. Other records of the use of these sheets include the projects of Isfahan 2 (Montazeri), Yazd (Sedighi), Parand, Abadan, Mahshahr, Shahid Rajaei and Shazand Arak power plants as the only domestically produced product.

   Farnam Baspar Company, with 22 years of experience in the automotive parts and geosynthetic products industry, produces this product with very good surface quality and excellent mechanical properties (resistance to cold, heat, moisture, and impact, etc.). Farnam Baspar does its best to achieve product quality through selecting appropriate raw materials.
