Composite Geomembrane

   The composite geomembrane liner has the advantages of geomembrane and geotextile at the same time. Geomembranes provide excellent seepage, leak, moisture, tear, and puncture resistance. The geotextile layer increases the tensile strength, and the composite geomembrane lining plays a great role in the landfill.

   On the basis of HDPE geomembrane, the composite geomembrane liner has both flexibility and ductility to improve the waterproof and seepage resistance.

   The composite geomembrane is thermally bonded by non-woven or woven geotextile and HDPE geomembrane through calendering technology. Composite geomembrane and geomembrane have the advantages of geomembrane and geotextile at the same time. It not only maintains the waterproof, anti-seepage, and tear resistance of the geomembrane while maintaining the characteristics of the geotextile but also protects the geomembrane.

Composite Geomembrane Price:

• The material has new material and recycled material, the new material price is high.
• According to the production process of blowing geomembrane and rolling, the price will be different.
• With different product thicknesses, the price is also different, common geomembrane thickness is 0.75mm, 1MM, 1.5mm, 2MM, and 3MM, the higher the thickness, the higher the price.
• The color of the product will also affect the price. Black is the most commonly used color, and other colors need to be customized, so the price will be high.

Composite Geomembrane Installation

Geotextile serves as a protective layer for geomembrane, protecting the anti-seepage layer from damage. To reduce ultraviolet radiation and increase anti-aging performance, it is best to use the buried method for laying.
(1) The buried method must be used: the covering thickness should not be less than 30cm.
(2) The renovation of the anti-seepage system should consist of: cushion layer, anti-seepage layer, transition layer, and protective layer.
(3) The soil should be solid to avoid uneven settlement and cracks. The grass and tree roots within the anti-seepage range should be removed. Sand or clay with small particle size should be laid as a protective layer on the contact surface with the membrane.
(4) When laying the geomembrane, do not pull it too tight. It is better to have the parts buried in the soil at both ends in a corrugated shape. Especially when anchored with rigid materials, a certain amount of expansion and contraction should be left.
(5) During construction, stones and heavy objects should be avoided from directly hitting the geomembrane. It is best to lay the membrane and cover the protective layer while constructing.

Composite Geomembrane Application

1. Composite geomembrane is suitable for water conservancy. Such as anti-seepage, plugging, reinforcement of dams of rivers, lakes, and reservoirs, anti-seepage of canals, vertical core walls, slope protection, etc.
2. Composite geomembrane can be used for environmental protection and sanitation. Such as landfills, sewage treatment plants, power plant conditioning pools, industrial, hospital solid waste, etc.
3. Composite geomembrane can be used in gardens, artificial lakes, rivers, reservoirs, pond bottoms of golf courses, slope protection, green lawns, etc.
4. Composite geomembrane can also be used for municipal engineering, subway, underground engineering of buildings, planting roofs, seepage prevention of roof gardens, and sewage pipes.
5. Composite geomembrane is suitable for mining, washing tanks, heap leaching tanks, ash dumps, dissolution tanks, sedimentation tanks, storage yards, tailings bottom lining anti-seepage, etc.
6. Petrochemical, chemical plants, refineries, oil storage tanks, seepage prevention, chemical reaction tanks, sedimentation tank linings, secondary linings, etc. can still use composite geomembrane.
7. The composite geomembrane is also used in aquaculture, intensive, factory farming ponds, fish ponds, lining of shrimp ponds, sea cucumber circle slope protection, and other fields.
8. Composite geomembrane can be used in the Salt industry, salt field crystallization pond, brine pond cover, salt geomembrane, and salt pond plastic geomembrane.
9. Composite geomembrane is also used in agriculture, reservoirs, drinking water pools, storage ponds, and anti-seepage irrigation systems.
10. Transportation facilities, foundation reinforcement of highways, and seepage prevention of culverts can be constructed with a composite geomembrane.
