Overview



Composite geomembranes are advanced geosynthetic composites that integrate the liquid - and gas - barrier properties of geomembranes with the reinforcing attributes of geotextiles. Typically, they consist of a geomembrane sheet, made from polymeric materials such as HDPE, LLDPE, or PVC, laminated or coated with a geotextile fabric. This combination results in a material that not only provides excellent containment but also exhibits improved mechanical behavior under various loading conditions.


The production of composite geomembranes involves meticulously controlled processes to ensure a strong bond between the two layers, maximizing their synergistic effects. These materials have gained widespread acceptance in numerous fields due to their ability to deliver reliable performance in challenging environments.



Features



Effective Liquid and Vapor Containment: The geomembrane component of the composite provides a reliable barrier against the migration of liquids and vapors. Its low permeability ensures that even trace amounts of contaminants are contained, making it suitable for applications with strict environmental requirements, such as hazardous waste containment and chemical storage facilities.


Chemical Compatibility: Composite geomembranes are available in various formulations to suit different chemical environments. The choice of geomembrane material and geotextile fabric is based on their chemical resistance properties, ensuring that the composite geomembrane remains stable and effective when exposed to specific chemicals or contaminants.


Thermal Stability: These materials maintain their performance across a wide range of temperatures. They do not become overly brittle in cold conditions or excessively flexible in hot conditions, ensuring consistent barrier performance and dimensional stability.


Easy Sealing and Connection: The smooth surface of the geomembrane layer facilitates the creation of effective seals using techniques such as heat welding or chemical bonding. The geotextile layer also helps to protect the seal during and after installation, ensuring the long - term integrity of the connections.


Eco - Friendly Solution: Composite geomembranes offer an environmentally friendly approach to containment and separation. By preventing the leakage of harmful substances and reducing the consumption of natural resources through efficient water management, they contribute to sustainable development and environmental protection.



Applications



Environmental Protection Projects: Composite geomembranes are widely used in the construction of landfill liners, landfill leachate collection systems, and landfill caps. They play a vital role in preventing the spread of pollution from waste sites and facilitating the safe disposal of municipal and industrial waste.


Water Resource Management: They are employed in the lining of reservoirs, dams, and canals to minimize water loss due to seepage. This helps to conserve water resources and improve the efficiency of water distribution systems, particularly in regions where water scarcity is a concern.


Mining and Mineral Processing: In the mining industry, composite geomembranes are used to line tailings ponds, heap leaching pads, and wastewater treatment facilities. They contain mining - related contaminants and prevent their release into the surrounding environment, supporting more sustainable and environmentally responsible mining practices.


Civil and Geotechnical Engineering: Applications in civil engineering include the lining of tunnels, culverts, and underground structures to prevent water infiltration and provide long - term waterproofing. They are also used in slope stabilization and erosion control projects to reinforce soil and prevent slope failures.


Energy and Fuel Storage: Composite geomembranes provide containment solutions for oil tanks, fuel storage facilities, and pipelines. They prevent leaks and spills, protecting the environment and ensuring the safe storage and transportation of energy resources.



FAQ



What is the difference between this product and the double-geotextile composite geomembrane?

The single-geotextile composite geomembrane has a structure of one geotextile layer plus one geomembrane layer, while the double-geotextile type has two geotextile layers sandwiching one geomembrane layer. The latter has better protection and reinforcement performance, and the former is more cost-effective for general scenarios.


What is the minimum peel strength requirement of this product?

The peel strength of the Single-Geotextile Composite Geomembrane is no less than 6 N/cm, which ensures a firm bond between the geotextile layer and the geomembrane layer, and avoids delamination during construction and use.


Does this product have good chemical compatibility?

Yes. The product can be formulated with different geomembrane materials and geotextile fabrics according to specific application scenarios. It has good chemical stability and can adapt to various chemical environments such as acid and alkali.


Is this composite geomembrane an eco-friendly product?

Yes. It is an environmentally friendly containment and separation solution. It can prevent the leakage of harmful substances, reduce water resource consumption through efficient water management, and contribute to sustainable development and environmental protection.
