Black and Green Geomembrane
A green geomembrane, also known as a black-green dual-color geomembrane, is a type of geomembrane usually made of high-density polyethylene (HDPE), It is commonly used in landfill closure and rainwater and sewage diversion projects.One side of the geomembrane is black. A certain carbon black content can ensure the anti-aging performance of the geomembrane. One side is green. Green can ensure the environmental protection and beauty of the landfill.

Why Peoppe Choose Green and Black Geomembrane
After the operation of a landfill, with the continuous deposition of waste, various issues such as leachate, landfill gases, and pest infestations may arise to varying degrees. Therefore, it is necessary to temporarily cover the landfill to address these concerns.
Benefits of temporary covering for a landfill site:
1，Rainwater and sewage diversion, reducing the volume of leachate to be treated.
2，Encapsulation, facilitating the collection of landfill gas.
3，Encapsulation, covering odors, facilitating environmental maintenance.
4，Reducing the use of clay layers, increasing storage capacity.
So, green geomembrane are primarily used for daily cover, intermediate cover, and final closure of landfill sites, it can also be applied in projects such as landscape lakes, swimming pools, water channels, and aquaculture reservoirs.
Funtions of Black and Green Geomembrane
A high-quality black-green dual-color geomembrane not only exhibits excellent anti-seepage effects but also possesses high puncture resistance, strong tensile strength, extended aging resistance, weather resistance, and chemical stability. It can withstand high temperatures up to 110°C and low temperatures down to -70°C, making it a reliable anti-seepage material. Additionally, it is resistant to corrosion from strong acids, alkalis, and oils.
This standard black-green geomembrane demonstrates robust tensile strength and elongation at break, allowing HDPE dual-color anti-seepage geomembranes to be used in various challenging geological and climatic conditions.
Issues to be Mindful of During Construction
When working with black-green dual-color geomembranes, attention should be given to the following issues during construction:
Substrate Preparation: Ensure the substrate is smooth, clean, and free from sharp or protruding objects to prevent damage to the geomembrane.
Seam Treatment: Proper treatment of seams between rolls of geomembrane is crucial. Employ professional seam methods to ensure secure and leak-free joints.
Temperature Control: Monitor ambient temperatures during construction to ensure proper laying and bonding of the geomembrane. Avoid construction in extreme temperatures to prevent adverse effects on the geomembrane's performance. When laying HDPE geomembranes, it is essential to consider the local temperature variations and the performance requirements of the HDPE geomembrane. Allow for the expansion and contraction caused by temperature changes and anticipate the expansion and contraction of the geomembrane based on the site topography and the conditions of geomembrane installation to accommodate uneven foundation settlement.
Protective Measures: Implement necessary protective measures on the construction site to prevent damage to the geomembrane from sharp tools, mechanical equipment, or other potential hazards.
Construction Personnel Training: Ensure construction personnel undergo professional training, understanding the correct construction methods and procedures to ensure effective use of the geomembrane.
Quality Control: Conduct quality control checks during construction to ensure the geomembrane meets specified standards.
