Geomembrane, also known as geosynthetic or geotextile, is an anti-penetration and reinforcing material used in civil engineering and geological engineering. It is usually made of synthetic fiber materials, such as polypropylene (PP) or polyester (PET), and is formed into a fiber network structure through a special processing process.

Geomembrane for Landfill
Due to their capacity to easily handle differential settling in the trash pile, geomembranes are suited for use in landfill caps, landfill coverings, landfill liners, temporary landfill closures, and more. PVC is the best environmental liner for these applications because of its high elongation and durability. To prevent rainfall leakage, they were first used as bottom liners for municipal garbage containment and landfill closures.
Geomembrane is an excellent geomembrane cover material for use in the following applications. They are used for landfill disposal facilities for municipal solid waste (MSW) and yard garbage (in numerous states), landfill disposal sites for low-hazard industrial waste, C&D construction and demolition waste debris, and other non-hazardous industrial trash, closure of the coal ash basin.
Geomembrane for Caps and Closures
Due to differential settlement and periodic gas pressure building from beneath, permanent geomembrane covers are subjected to a large level of strain in all directions. Caps are frequently used to cover sloped regions and are designed to hold a layer of other geosynthetics and soil above them for an extended period of time. In general, geomembrane covers are used to protect materials from water penetration and to reduce material loss due to wind or water erosion. Covers can also help to keep odors at bay.
Soil rehabilitation initiatives, temporary stockpile covers, and erosion protection on slopes in active construction sites are all examples of short-term cover applications. Covers or caps for landfill closures are examples of long-term applications. Another use is to increase the life of the roofs of above-ground storage tanks.
Geo-membrane for Pond Liner
Pond liners provide a variety of benefits, but not all of them are created equal. Even the same-material liners can function differently. The Geosynthetic Institute is responsible for developing test techniques, standards of practice, and product specifications for geosynthetics such as HDPE liner production, design, and installation.
Pond liners are robust and flexible, with excellent chemical and corrosion resistance. They are among the most long-lasting and robust polyethylene liners available. They can be fusion welded together in the field to make permanent sealing. To ensure a flawless installation, fusion welding requires an expert welder and accompanying equipment. Both fish and vegetation are safe in pond liners. Overall, liners are inexpensive and have one of the longest service lives of any polyethylene liners.
Geomembrane for Mining
The HDPE geomembrane liner serves as a separation barrier and is also the most significant component in heap leaching in this application. Chemical, point loads from normally high heap loading conditions, site-specific terrain, site-specific climate conditions, and site-specific building conditions must all be considered while designing the geomembrane. Geomembrane is a cost-effective composite liner system alternative, especially if on-site clay sources are insufficient.
A bentonite (water-absorbing material) layer is sandwiched between two nonwoven geotextile layers in GCL. A 10 mm thick GCL will often operate similarly to, if not better than, a 30 cm CCL, and may even self-heal. Additional filtration and barrier capabilities are provided by GCL. The nonwoven geotextile protection layer helps disperse loads and provides support for the underlying geomembrane. By keeping small particles and gravel from accessing the geomembrane, the protective layer also aids filtration and drainage.
Geomembrane for Canal Liners
Geomembranes are often used to prevent water from seeping into canals. HDPE, LDPE, and LLDPE geomembranes are among the various varieties of geomembranes available for this application. These geomembranes frequently require protection, and there are a variety of choices available, including compacted earth, concrete, or shotcrete. The United States Bureau of Reclamation (USBR) has done a variety of tests on canal-lining systems, including the Deschutes Canal-Lining Demonstration Project, which entails the completion of 34 canal test sections, many of which use geomembranes.
-
Impermeability: HDPE geomembranes provide excellent impermeability, acting as a highly effective barrier against water, gases, and liquids. They prevent the seepage of water, contaminants, and pollutants into the surrounding soil or groundwater, thereby protecting the environment and preserving valuable resources.
-
Chemical resistance: HDPE geomembranes exhibit exceptional resistance to a wide range of chemicals, including acids, alkalis, and organic solvents. This resistance allows them to withstand exposure to aggressive substances commonly found in industrial, agricultural, and waste management applications.
-
Durability: HDPE geomembranes are highly durable and possess excellent resistance to UV radiation, oxidation, and weathering. They can withstand long-term exposure to harsh environmental conditions, ensuring their integrity and performance over time. This durability translates into long service life and reduced maintenance costs.
-
Flexibility: HDPE geomembranes are flexible and conformable, enabling them to adapt to irregular subgrades and accommodate ground movements or settlement. This flexibility simplifies the installation process and allows for efficient lining of various structures, such as ponds, canals, landfills, and reservoirs.
-
High tensile strength: HDPE geomembranes have high tensile strength, which provides resistance against tearing, puncturing, and abrasion. This strength allows them to withstand mechanical stresses during installation and operation, ensuring the integrity of the lining system.
-
Ease of installation: HDPE geomembranes are lightweight and easy to handle, facilitating their installation in different types of projects. They can be factory-welded into large panels, reducing the number of field seams and minimizing the risk of leaks. Additionally, their flexibility allows for efficient installation even in challenging terrains.
-
Environmental friendliness: HDPE geomembranes are environmentally friendly and have a low environmental impact. They are chemically inert and do not release harmful substances into the soil or water, ensuring the protection of ecosystems. Furthermore, HDPE is a recyclable material, promoting sustainability and reducing waste generation.
-
Versatility: HDPE geomembranes can be fabricated into various sizes, thicknesses, and configurations to suit specific project requirements. They are widely used in applications such as landfill liners, mining heap leach pads, wastewater treatment facilities, agricultural ponds, and decorative water features.
HDPE, LDPE & LLDPE Film/Sheet/Liner, having long term durability of strength, flexibility, UV and chemical resistance, extensive range of products most widely used in civil and agricultural fields, irrigation, water and solid waste management, fluid conveyance and containment, ash ponds, soil protection and stabilization, land fills clousers , ponds and reservoirs, irrigation canals and waste treatment plants.
Several factors affect the degradation of polymers within the geomembranes. Factors like UV exposure, chemical impact, biological contaminants (animal, fungi) and thermal expansion impact the life span of the geomembranes.
Technical expertise is necessary when selecting the right type and thickness for the project. This is generally based on the depth of the containment and the geo technical conditions of the site.
