Geomembranes are flexible sheet materials that are commonly used as barriers to prevent the passage of gases, liquids, or solids. They are known for their long-term durability, strength, flexibility, and chemical resistance, extensive range of products 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..There are several types of geomembranes available, including PVC (Polyvinyl Chloride) liners and Polyethylene liners (HDPE and LLDPE).

- Tailings management: Geomembranes can be used to line tailings ponds, preventing the leakage of toxic chemicals and heavy metals into the environment.
- Water management: Geomembranes can help manage water resources in mining operations, such as lining water storage ponds, preventing water contamination, and reducing evaporation.
- Waste containment: Geomembranes can be used to contain and manage mining waste, including hazardous materials, to prevent environmental pollution.
- Heap leach pads: Geomembranes can be used to line heap leach pads, allowing for the efficient extraction of metals from ore while preventing environmental contamination.
- Process water storage: Geomembranes can be used to store process water, reducing the risk of contamination and ensuring a reliable water supply for mining operations.
These applications can help minimize environmental impacts, reduce costs, and improve operational efficiency in the mining industry.
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.
Please see the corresponding depth and thickness chart for a general overview. This is for guidance only, speak out for advice relevant to your requirements.
