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 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.
