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

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)
