Geomembranes are mainly made of HDPE (high density polyethylene sheet), LLDPE (low-density polyethylene sheet), PP (polypropylene) and PVC (polyvinyl chloride) and are VFPE which highly flexible and are used based on the type of polymeric materials used in the structure of these sheets such as: plasticizers, carbon blocks, Vulcanizes, lubricants and other additives. Geomembrane sheets are manufactured in two methods of rolling (lava flow into the rotating rollers) and intravenous (flow the molten polymer resin material through the wiredraws by the rotating injection device). The sheets are available in various thicknesses (from 75/0 mm to 2 mm), and in various forms (ridged or smooth).

Geomembrane Applications
- Construction of artificial lakes and decorative fountains
- Construction of wastewater treatment lagoons
- Construction of urban and industrial landfills
- Construction of drinking water tanks
- Construction of artificial lakes
- Construction of fish farm shrimps
- Construction of sediment retention pools made by industrial factories, mineral and chemical pollutants
- Isolation and sealing of tunnels and subway and buried structures in soil such as Metro
- Construction of agricultural ponds
- Construction of water canals
- Construction of rubber dams

Advantages of Geomembranes:
- Significantly reduce implementation time and increase the speed of construction
- Create a totally isolated and sealed surfaces in comparison with concrete and clay surfaces
- Ease of constructing lakes, reservoirs and ... in different forms
- Good resistance to oil and chemicals materials.
- Good resistance against weathering and environmental factors and UV radiation
- No decay and destruction occurs in adjacent to soil and moisture (especially in isolating underground structures with long useful life like Subway)
- Easy to repair in operation time
