Smooth or Textured 45 Mil Hdpe Pond Liner , Fish Farm Geomembrane Liner
Agricultural Pond Liner 45 Mil Hdpe Geomembranes for Fish Farm
- HDPE is a very technical product to work with. It must be installed by certified welding technicians using specialized welding equipment to ensure performance.
- Installations are temperature and poor weather sensitive.
- 40 mil HDPE liner requires extra effort to ensure that the subgrade is in excellent condition. It is suitable as an upgrade from products like the 20 mil RPE for larger installations and is an excellent secondary containment liner on multi-layer systems (for example; subgrade, geotextile layer, 40 mil
- HDPE layer, drainage net layer, 60 mil HDPE layer, geotextile layer, fill.)
- 60 mil HDPE liner is the staple of the industry and is suitable for most applications.
- 80 mil HDPE liner is a thicker design for more aggressive subgrades.

HDPE geomembrane application areas
Agriculture and Aquaculture
Definition: Improve agricultural production efficiency through anti-seepage and isolation functions.
Fish pond/shrimp pond: 0.5-1.0mm film thickness for anti-seepage, 30% increase in yield, 60% reduction in disease.
Methane tank/irrigation system: 1.5mm film thickness to resist methane corrosion, 2 times longer service life than traditional concrete structures.
Mining and industrial anti-seepage
Prevent mining waste liquid and chemical raw materials from polluting the surrounding environment.
Tailings pond anti-seepage: 1.5-2.0mm rough surface membrane resists puncture of sharp objects in ore, reducing leakage accident rate by 85%.
Chemical plant storage tank area: double-layer membrane + leakage detection system, in line with GB18598-2019 hazardous waste landfill standards.
Innovation:
Conductive HDPE membrane: integrated carbon fiber sensor network, real-time monitoring of leakage location (accuracy up to ±0.5m).
Municipal and construction engineering
Solve the problem of waterproofing and moisture-proofing in urban underground spaces.
Subway tunnels: Used in combination with ECB waterproofing boards, the anti-settling deformation capacity reaches 300% elongation.
Roof gardens: Anti-root thorn formula membrane (with chemical root inhibitors) replaces traditional asphalt waterproofing layers, reducing weight by 70%.
Trends:
Photovoltaic integration: Transparent HDPE membrane (85% transmittance) is used in agricultural photovoltaic greenhouses to achieve dual benefits of power generation and planting.
