Flexible membranes are used in a variety of applications, such as:
to protect the ground water from contamination.
to prevent fluid flow in the landfill, to trap and properly vent the gases generated during decomposition of organic waste and to permit efficient revegetation and restoration of the area.
for collecting rain-water before it reaches the sea.
Reservoirs for waste-water
to protect the groundwater sources or streams.
for artificial lakes and irrigation of farms.
an economic alternative to concrete and compacted earth for transporting water and irrigating large areas. Also used to reduce seepage from existing deteriorated concrete linings.
Protection of lake banks
for soil stabilization.
protecting the structure against humidity and water pressure.
for soil stabilization.
of chemical plants, petrol stations & roads to prevent chemicals, oil etc. from polluting the underground water in case of a leakage.
for preventing contamination of the soil and underground water and permitting extraction of precious metals by heap leaching, using chemical solutions.
secondary lining for preventing pollution in case of leakage or chemical spill.
Insulation of buildings & construction projects
Water reservoirs for fish breeding.
