Applications and Benefits of Geomembranes in Agricultural Water Conservancy

Applications

1. Canal Seepage Prevention

• Reduces Water Loss: Geomembranes have extremely low permeability. When installed on canal beds and slopes, they effectively minimize water seepage, improving irrigation efficiency. For example, in arid regions, geomembranes can reduce canal leakage by over 90%.

• Prevents Erosion: By separating water flow from soil, geomembranes protect canal structures from erosion, enhancing stability and longevity.

• Easy and Fast Construction: Lightweight and customizable, geomembranes can be quickly cut, spliced, and installed, significantly reducing construction or repair time.

2. Reservoir and Cistern Construction

• Superior Seepage Control: Used as liners, geomembranes prevent water leakage, ensuring reliable water storage for irrigation and livestock. In water-scarce regions, they minimize evaporation and seepage, optimizing water conservation.

• Cost-Effective Design: Compared to traditional brick or concrete structures, geomembrane-based reservoirs and cisterns require fewer materials and simpler techniques, lowering costs.

3. Saline-Alkali Soil Improvement

• Blocks Salt Migration: Installed below the topsoil, geomembranes isolate saline groundwater, preventing salt damage to crop roots and creating healthier soil conditions.

• Accelerates Desalination: Combined with drainage systems, geomembranes facilitate salt removal with water discharge, speeding up soil desalination and improving fertility for better crop yields.

Implementation Considerations

For optimal performance, geomembrane type and specifications must be selected based on project needs and geological conditions. Strict adherence to installation standards ensures long-term seepage control and durability.

Key Advantages:
✔ Water Conservation – Minimizes seepage & evaporation.
✔ Cost Efficiency – Reduces construction & maintenance expenses.
✔ Soil Protection – Enhances land productivity in saline areas.
✔ Durability – Resists erosion and extends infrastructure lifespan.
