About geo-membranes:

• They are impermeable membranes, used where the primary function is to have an impervious barrier for fluids.
• However, as the possibility of punctures or tears is high in many areas of use, it is common to protect these membranes by use of Geotextiles.
• Often the geotextiles also perform other functions besides protection of the membrane.
  
  
• Geomembranes are made from continuous polymeric sheets that are very flexible, but can also be made by impregnation of geotextile with asphalt or elastomeric sprays or bitumen composites. Geomembranes are used in applications such as liners for water canals, waste canals, solid-waste landfills, covers for solid-waste landfills, waterproofing within tunnels, to control odors in landfills, to prevent infiltration of water in sensitive areas, and beneath asphalt overlays as a waterproofing layer.
