Composite geomembrane combines an impermeable film with nonwoven geotextile on one or both sides, giving waterproofing and filtration in a single roll. The fabric layer protects the film from puncture and works as a filter, which simplifies installation and lowers overall system cost in canal, artificial lake, reservoir and landfill capping applications.
Specifications

| Standard | GB/T 17642 (Nonwoven Composite Geomembrane) |
| Film Thickness | 0.3 – 2.0 mm |
| Fabric Weight | 100 – 400 g/m² (one or both sides) |
| Peel Strength | ≥30 N/cm (hot-melt lamination) |
| Permeability | ≤1.0×10⁻¹² cm/s order |
| Roll Width | 3 – 6 m, custom available |
One-Side vs Two-Side Fabric — How to Choose
- Two-side fabric (two cloth, one membrane): double protection, higher puncture and tear resistance — best for poor base conditions and areas needing protection on both sides.
- One-side fabric (one cloth, one membrane): single-side protection at lower cost — ideal for well-prepared canal and reservoir bases.
- For demanding projects, select fabric weight and film thickness by zone to balance performance and budget.
Typical Applications
- Irrigation canal lining and anti-seepage
- Landfill final capping cover (with drainage layer)
- Artificial lakes, landscape water bodies and fish ponds
- Reservoir and pond embankment protection
Quality You Can Verify
Peel strength (≥30N/cm) means the fabric and film will not delaminate during installation or welding. Every batch ships with its test report covering thickness, tensile, peel and permeability — third-party re-testing on random rolls is welcome before delivery.
