1. What Is A Composite Geomembrane Liner?
Composite Geomembrane Liner is a specialized material that combines geotextiles and geomembranes to create an impermeable barrier for various applications. It is produced by heat-bonding nonwoven or woven geotextile layers to HDPE geomembranes using calendaring processing technology.
BPM brand composite Geomembrane liner, for example, is manufactured by pressing one or two geotextile layers onto the geomembrane layer in a continuous far infrared ray heating oven. The production process involves the addition of polymer and anti-aging materials, which enhance its performance in unconventional temperature environments.
The composite geomembrane liner offers high physical and mechanical properties, including tensile strength, tear resistance, and bursting strength. This makes it suitable for diverse civil engineering projects such as water conservancy, municipal administration, construction, transportation, subway, and tunnel applications.
The composite geomembrane liner provides a multifunctional solution by combining the advantages of geotextiles and geomembranes,. The geotextile layer enhances tensile strength, while the geomembrane layer ensures impermeability, effectively preventing leaks and moisture penetration.
The applications of composite geomembrane liners are extensive. In landfills, they act as a barrier to prevent the migration of contaminants into the surrounding soil and groundwater. Wastewater treatment facilities utilize these liners to contain and manage effluent, ensuring proper treatment and disposal. During road construction, composite geomembrane liners provide stability and prevent moisture ingress, enhancing the durability of road structures. In aquaculture, they create secure containment systems for fish or shrimp farming, preventing water contamination and facilitating proper management. Composite geomembrane liners find application in landscaping and agriculture. They offer erosion control, water retention, and protection against soil contamination, contributing to sustainable and environmentally friendly practices.

3. What Are Features of Composite Geomembrane Liner?
composite geomembrane liners offer a range of features including the combined benefits of geotextiles and geomembranes, options for textured or smooth surfaces, enhanced durability, high tensile and tearing strength, chemical and UV resistance, reduced potential for delamination, simplified installation, OEM/ODM availability, and competitive factory pricing. These features make composite geomembrane liners suitable for diverse applications requiring impermeable barriers or containment systems.
3.1 Benefits of Geotextiles and Geomembranes
Composite geomembrane liners combine the advantages of geotextiles and geomembranes in a single product. This integration allows for enhanced performance and functionality, as the geotextile layer provides additional properties such as filtration, separation, reinforcement, and drainage, while the geomembrane layer ensures impermeability.
3.2 Textured or Smooth Surfaces
Composite geomembrane liners are available with options for textured or smooth surfaces. Textured surfaces provide increased friction coefficient, which improves stability and prevents slippage in slope and containment applications.
3.3 Enhanced Durability and High Friction Coefficient
The combination of geotextiles and geomembranes in composite geomembranes enhances durability and resistance to mechanical stresses. The geotextile layer helps distribute loads and protects against punctures or abrasions, thereby extending the overall lifespan of the liner system. Additionally, the high friction coefficient of composite geomembranes improves stability and reduces the risk of slippage.
3.4 High Tensile and Tearing Strength, Anti-Puncture
Composite geomembrane liners exhibit high tensile and tearing strength, making them resistant to ruptures and tears. They also provide excellent puncture resistance, ensuring reliable containment and preventing leakage.
