Product Introduction
Composite geomembrane liner combines 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. This composition makes it possible to obtain a geomembrane with specific properties in addition to reducing the manipulations and the time required for the installation of a multilayer system.
Composite geomembrane liners combine the benefits of geotextiles and geomembranes to provide a versatile solution for impermeable barriers. It is widel used in various industries, including landfill management, wastewater treatment, road construction, aquaculture, landscaping, agriculture, and more.Its versatility and effectiveness make it a preferred choice for projects requiring impermeability, durability, and protection against environmental hazards.
As the leading geomembrane manufacturer and supplier, BPM offers high quality custom composite geomembrane for you needs at best factory price.
Product Properties
The composite geomembrane has a certain amount of deformation, and the stress transfer and dispersion speed of the concave and convex defects of the base cushion are fast, and the strain capacity is strong. The pore pressure and buoyancy on the interface between composite geomembrane and soil are easy to dissipate. It has a certain heat preservation effect, increased the soil frost heave on the destruction of geomembrane and HDPE geomembrane, thus increasing the soil deformation. In addition, the composite geomembrane has excellent anti-aging function and engineering maintenance and other advantages
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.
