Production Description:
The double-sided green geomembrane is generally used for the final cover of the landfill site. Specifically, it is a covering layer system laid on the top of the landfill site after the completion of the landfill. It is the follow-up stage and the key stage of landfill operation. The final cover system of landfill provides cover protection for waste, and it is also the basis of land use and recovery of landfill.
The Geomembrane liners are plastic sheets or films made of High Density Polyethylene (HDPE), Low density Polyethylene (LDPE) and linear low density polyethelene(LLDPE) by film blown or extrusion process. HDPE Geomembranes are the most popular anti seepage material. They're the high density version of PE plastic and is harder and denser than the LDPE. Their main component is 97.5% HDPE resin,about 2.5% is carbon black, anti aging component, anti oxidizing component, UV absorbent and stabilizer and so on. They are manufactured under permanent quality control and comply with national and international standards.
It has excellent temperature adaptability, weldability, tolerance and aging resistance, chemical corrosion resistance, environmental stress cracking resistance and anti pierce performance. Therefore, it is especially suitable for underground engineering, mining engineering, sewage and waste residue treatment plant as impermeable materials.

Application:
- Reduce rainwater and external water infiltration into the body of garbage heap to achieve the purpose of reducing landfill leachate
- To control the odor emission of the landfill, the combustible gas from the upper part of the landfill can be dispersed and collected in an organized way, so as to achieve the purpose of pollution control and comprehensive utilization
-
Inhibition of reproduction and spread of pathogens and their vectors
- To prevent surface runoff from being polluted, to avoid the spread of garbage and its contact with people and animals
- Prevent soil erosion
-
Promote the stabilization of garbage dump as soon as possible
-
It can provide a landscaping surface, provide soil for the growth of vegetation, and facilitate the reuse of landfill land
Advantage:
- Effective isolation of liquids and gases
- The flexibility of the material is suitable for landfill closure
- Anti leakage
- Moisture-proof
- Isolation
- Root resistance
- Anti puncture
- Resistance to environmental stress cracking
Package:
Rolling with pipe in core, double layer woven bags with strengthened belt for unloading convenience and protecting.
