Introduction to geomembranes and their types

Geomembranes are impermeable membranes that prevent fluid migration and enhance terrain stability in human projects, systems or structures. They are made from impermeable geosynthetic material and consist of thin, continuous sheets of polymers. Still, a few types of geomembranes are manufactured by combining geotextiles with asphalt, elastomer or polymers, and multilayered bitumen geocomposites. Geomembranes made from continuous polymer sheets can be used in various applications, including civil and mining, transportation, and environmental applications. They are cost-effective and have properties to solve problems related to soil reinforcement, erosion control, and soil containment.

By forming an impenetrable barrier, geomembrane sheets stop pollutants or hazardous compounds from leaking into the environment. It is frequently utilised as containment barriers for irrigation and potable water storage requirements to stop leaks. In mining, sewage treatment, and canal building projects, geomembranes are combined with other geosynthetic materials to regulate fluid flow and for safe containment. This blog covers types of geomembranes suitable for various industrial applications:

Types of geomembranes

  1. HDPE geomembranes

    HDPE ( high-density polyethylene) has the properties of strong UV/ temperature resistance, durability, and high chemical resistance. Along with this, HDPE has a low manufacturing cost. This makes HDPE geomembranes the first choice for pond lining, canal lining, landfills, reservoir projects and several other industries. HDPE geomembranes offer high protection levels due to increased thickness compared to other types of geomembranes. Strong chemical resistance properties enable HDPE to be used for storing drinking water.

  2. LLDPE geomembrane

    LLDPE ( linear low-density polyethylene) geomembranes are manufactured from virgin polyethylene resins. They are strong, durable, and have UV-resistant properties. LLDPE geomembranes are the preferred choice for engineers and installers who require higher flexibility than HDPE geomembranes. They are commonly used in industrial applications, animal and industrial waste contaminants, and liquid storage tanks.

  3. PVC geomembrane

    PVC geomembranes (polyvinyl chloride) are thermoplastic, waterproofing sheets made with vinyl, plasticisers, and stabilisers. They are manufactured by splitting ethylene dichloride into a dichloride and polymerising the end-product for polyvinyl chloride resin used in PVC geomembranes. As PVC geomembrane is tear, abrasion, and puncture-resistant, it is used to line tanks, landfills, wastewater lagoons, canals, and for soil stabilisation. PVC geomembranes also guard effectively against contaminants trying to enter water sources.

  4. RPP geomembrane

    In RPP (reinforced polypropylene) geomembranes, UV-stabilised polypropylene copolymer is used, giving the geomembrane chemical resistance, flexibility, and material stability. The geomembrane durability of RPP is further enhanced with nylon scrims. RPP geomembranes are commonly used across all industrial sectors for long-term water containment and waste applications. They are also used for municipal applications, evaporation pond liners, etc.

  5. TRP geomembrane

    TRP (reinforced polyethylene) geomembranes are manufactured from polyethylene fabric. They have a low-temperature range, chemical resistance, and UV stability. TRP geomembranes are used for landfills, canals, soil remediation, lining temporary ponds, and other agricultural applications.

  6. EPDM geomembrane

    EPDM ( ethylene propylene diene monomer ) geomembranes have a rubber-like texture because of the manufacturing process, which enhances geomembrane durability. The rubbery texture makes it a durable, UV-resistant, strong and flexible geomembrane. EPDM geomembranes are used during extreme weather conditions. They cannot be punctured easily due to their texture. EPDM geomembranes offer easy installation and are generally used as surface barriers for dams, liners, covers, and backyard landscaping.


High-quality geomembrane liners are crucial for environmental, construction, mining, and oil projects. Choosing the best type of membrane that is cost-effective, fulfils your requirements, and complies with environmental regulations is essential for operational excellence.
