Important applications of geomembranes in various industries

A geomembrane is a very low permeability synthetic membrane liner or barrier used with any geotechnical material to control the migration of fluids (liquids or gases) in a man-made project, structure or system. Geomembranes are made from relatively thin continuous sheets of polymer, but they can also be made by impregnating geotextiles with sprays of asphalt, elastomer, or polymers, or as multi-layer bituminous geocomposites. Continuous polymer sheet geomembranes are by far the most common.

Geomembranes have variety of applications

Geomembranes have been used in the following environmental, geotechnical, hydraulic, transportation and private development applications:

  • As a liner for drinking water
  • As a liner for reserve water (e.g. safe shutdown of nuclear facilities)
  • As a liner for liquid waste (e.g. sewage sludge)
  • Coatings for radioactive or hazardous liquid waste
  • As a liner for secondary containment of underground storage tanks
  • As foil for solar ponds
  • As a coating for saline solutions
  • As a liner for the agricultural industry
  • As liners for the aquaculture industry, e.g. B. Fish/Shrimp Ponds
  • As a coating for water holes and sand bunkers on golf courses
  • As a sheet for all types of ornamental and architectural ponds
  • As a coating for water supply channels
  • As a lining for various waste transport channels
  • As a liner for primary, secondary and/or tertiary landfills and landfills
  • As liners for heap leach pads
  • As covers (plugs) for landfills
  • As covers for aerobic and anaerobic slurry tanks in agriculture
  • As covers for steam coal ashes
  • In lining of vertical walls: single or double with leak detection
  • As barriers in zoned earth embankments to prevent seepage
  • As liners for emergency overflows
  • As a sealing coating in tunnels and pipelines
  • As a watertight lining for earth and rockfill dams
  • As a waterproof coating for roller-compacted dams
  • As a waterproof coating for masonry and dam walls
  • Interior cofferdams for leachate control
  • As a pool for leachate control
    As floating container lids to prevent contamination
  • For storing and transporting liquids in trucks
  • To receive and transport drinking water and other liquids in the ocean
  • As a barrier against landfill odors
  • As a barrier against vapors (radon, hydrocarbons, etc.) under buildings
  • To check extensive soils
  • To combat frost-sensitive soils
  • To protect sink-prone areas from running water
  • To prevent water from entering sensitive areas
  • to form barrier pipes like dams
  • Facing structural supports as temporary cofferdams
  • To direct water flow in preferred paths
  • Under highways to avoid contamination from de-icing salts
  • Under and along highways to contain hazardous liquid spills
  • As capture structures for temporary loads
  • To help establish uniform subsoil compressibility and settlement
  • Under asphalt coatings as a sealing layer
  • To contain seepage losses in existing aboveground tanks
  • In the form of flexible shapes where no loss of material is allowed.
