Our composite geomembranes combine high-performance polymeric barriers with protective geotextiles or bentonite cores in a factory-bonded system. Delivering zero-leak integrity, these engineered solutions outperform single-layer liners with certified hydraulic isolation for critical containment projects.
| Composite Type | Structure | Ideal For |
|---|---|---|
| GM-GT (Reinforced) | Geomembrane + Nonwoven Geotextile | Landfill caps, mining leach pads |
| GCL-GM (Bentonite) | Bentonite core + Geomembrane | Secondary containment, ponds |
| GM-GT-GM (Sandwich) | Dual geomembranes with geotextile core | Hazardous waste, fuel storage |
✅ Enhanced Protection
Geotextile layer absorbs punctures (CBR > 3,500N)
300% longer service life vs. exposed geomembranes
✅ Guaranteed Hydraulic Performance
Permeability: ≤1×10⁻¹³ cm/s (ASTM E96)
Zero leakage at seams (factory pre-bonding)
✅ Installation Efficiency
40% faster deployment (no separate protection layer)
Pre-qualified seam integrity (destructive tested)
✅ Lifecycle Cost Savings
Eliminates $8–15/m² separate geotextile costs
Reduces leakage liability by 90% (GRI studies)
