Composite Geomembrane
Description
Composite geomembrane is a combination of geotextile and geomembrane liners, creating an impermeable material. This product combines the benefits of both geomembranes and geotextiles. It is primarily utilized for anti-seepage applications in waste landfills, road construction, and fish ponds. The composite geomembrane effectively prevents the migration of liquids and provides excellent seepage control, making it an ideal solution for projects requiring reliable containment and environmental protection.
As the leading geomembrane manufacturer and supplier, GEOSINCERE offers high quality custom composite geomembrane at best factroy price.
1. What Is Composite Geomembrane?
Composite geomembrane is a geosynthetic material that combines the benefits of geotextiles and geomembranes. It consists of multiple layers bonded together to form a single unit. The geomembrane layer is typically made of materials like HDPE, LLDPE, PVC, or EPDM, providing excellent chemical resistance and durability. The geotextile layer, composed of synthetic fibers, offers added strength, puncture resistance, and filtration properties.
Composite geomembranes can be produced through thermal bonding using non-woven or woven geotextiles and HDPE geomembranes. Another method involves casting, resulting in different configurations such as one layer of geotextile and one layer of geomembrane, two layers of geotextile and one layer of geomembrane, or vice versa.
The geotextile layer acts as a protective barrier for the geomembrane, safeguarding it against damage. To enhance UV resistance and anti-aging properties, proper installation methods should be followed. During construction, a layer of sand or clay is placed on the base surface, followed by the placement of the geomembrane. The geomembrane should not be stretched tightly, and the ends should be buried with soil to allow for corrugation. A transition layer of fine sand or clay is then added, followed by a protective layer of stone or concrete blocks. Care should be taken to avoid direct impact of stones on the geomembrane, and the protective layer should be constructed on the side of the geomembrane.
Composite geomembrane liners are created by combining non-woven geotextile with smooth HDPE geomembrane liner through heat-bonding and calendaring processes. The resulting liner exhibits the advantages of both geotextiles and geomembranes. The geotextile layer enhances tensile strength, while the geomembrane layer provides impermeability, leak resistance, moisture proofing, tear resistance, and puncture resistance. With excellent quality and adaptability, composite geomembrane liners are widely used in applications such as landfills, wastewater treatment, road construction, aquaculture, landscaping, and agriculture.
