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.

Core Technologies & Configurations

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

Why Choose Composite Over Single-Layer?

✅ 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)
