Geomembranes are made from impermeable geosynthetic material consisting of thin continuous sheets of polymers. Geomembranes create an impermeable barrier that prevents the leakage of harmful contaminants or dangerous chemicals to surrounding environments. It is also regularly used as containment barriers for potable water and irrigation storage requirements to prevent leakage. Geomembranes are used in conjunction with other geosynthetic products to control fluid movement and provide containment in projects related to mining, sewage treatment and canal construction.
The growing application of geomembranes is noticeable in different industries due to the versatility of the product. Geomembranes have a wide range of applications in industries such as mining, marine, civil, water treatment and transportation. Some of the applications are detailed below.

Usage of geomembrane in the mining industry started in the 1970s and has increased thereafter. It is used as a lining solution for evaporation ponds, heap leach pads and tailing impoundments.
The design and construction of these heap leach pads are regulated to protect the environment from exposure to harmful chemicals so a lining system, usually a HDPE geomembrane, forms a critical component in construction of these heap leach facilities.
Geomembranes are also used during the end of a mine's lifespan. As a part of mine restoration, HDPE liners are used to seal the mine and prevent waste products from contaminating the surrounding environment. Overall, geomembrane lining is a safe and effective solution to protect the environment from harmful industries.
Water Industry
HDPE geomembranes play a major role in delivering clean water to the community. They are used in services related to drinking water and wastewater including sewage treatment. When canals, dams and reservoirs are sealed with geomembrane liners they avoid contamination from groundwater.
Geomembrane is also used to prevent contamination of potable water from soil and other pollutants as well as preventing loss of water through infiltration of the water into the surrounding soil. Lining a dam or canal can minimise seepage thereby improving the efficiency of storage and transportation. Geomembranes are also used as a secondary containment for underground storage tanks, solar ponds and brine solution.
