There is increasing application of geomembranes in several industries because of their versatility. Some of the sectors that register extensive use of geomembrane liners include:
1. Agricultural Sector – Farmers extensively use geomembrane liners in dam and pond lining since they offer reliable and cost-effective containment solutions. They also serve numerous roles in nurseries such as waterproofing and soil containment.
2. Mining Industry – Geomembrane in mining serve as lining solutions for tailing impoundments, heap leach pads, and evaporation pads. The geomembrane barriers prevent environmental pollution by hazardous chemicals from the mines.
3. Water Industry – There is immense geomembrane application in wastewater and drinking water treatment plants. The material prevents groundwater contamination when used to seal reservoirs, dams and canals.
Geomembrane liners are also valuable in avoiding potable water contamination by soil and other contaminants. It also hinders water loss via infiltration into the bordering soil.
Lining a canal or dam can reduce seepage, which enhances transportation and storage efficiency. Moreover, geomembrane linings also act as auxiliary containment for solar ponds, underground storage tanks, and brine solution.
4. Marine Industry – HDPE geomembranes find immense use in marine industry, especially in the building of jetty platforms or floating docks reinforced by pontoons. They give a protective barrier that elevates the longevity of the structure.
The HDPE geomembrane barrier guards the construction from destruction by environmental elements, marine life, and other pollutants inside the water. It equally provides the pontoon with extra buoyancy and avoids degeneration due to severe weather conditions, enhancing the general resilience of the pontoon.
5. Solid Waste Management Sector – Use of Geomembranes for landfills include employing them as landfill coverings or closures, cut-off walls, and base liners for leachate and waste containment. Landfills often incorporate composite liners comprising of geomembrane and geosynthetic clay liner.
6. Civil Construction – Civil engineering projects immensely use geomembrane liners, from integrated drainage systems, tunnels to roads and dams. They are essential in quickening installation times and controlling expenses whilst safeguarding existing structures. Furthermore, geomembranes are applied in geotechnics industry to curb flow issues, deformation, and failure load.
