Eurobent™ Geosynthetic Clay Liners (GCL) | South Africa
Reinforced needle-punched geosynthetic clay liners (GBR-C) with a natural sodium bentonite core, engineered with a Thermal Locking system
Reinforced Needle-Punched Bentonite Barrier Systems – South Africa
Geosynthetics Africa supplies Eurobent™ Geosynthetic Clay Liners (GCL) across South Africa and Africa for landfill lining, mining containment, tailings storage facilities (TSF), secondary containment systems and civil environmental barriers.
Eurobent GCL is a factory-manufactured hydraulic barrier consisting of high-swelling natural sodium bentonite encapsulated between geotextiles and mechanically reinforced through needle-punching and thermal locking.
The result is a low-permeability, self-sealing bentonite barrier engineered for long-term environmental containment performance.
Thermal-Lock Bonding: Superior Structural Integrity
EuroBent™ GCLs are constructed with Thermal-Lock bonding, where the nonwoven geotextile is heat-fused to the woven carrier layer after needle-punching. This:
Enhances internal shear strength for slopes and elevated load conditions
Prevents bentonite migration even under settlement or hydration
Improves durability and resistance to puncture or pull-out forces
Maintains consistent liner performance throughout installation and service life
Why Choose EuroBent™ GCLs?
Engineered to ISO 10318-1 standard: GBR-C classification
High-purity natural sodium bentonite core
Ultra-low hydraulic conductivity (≤ 5.0 × 10⁻¹¹ m/s)
Lightweight, roll-based system for rapid installation
Lower CO₂ impact than compacted clay liners
Available in multiple performance grades (EB3500 to EB6000)
Applications of EuroBent™ GCLs
EuroBent™ GCLs provide impermeable containment in:
Mining: tailings dams, leach pads, processing ponds
Waste: municipal and industrial landfill liners and capping
Water: stormwater basins, dams, canals, and irrigation ponds
Civil Infrastructure: road embankments, tunnels, culverts
Agriculture & Aquaculture: fish ponds, lined reservoirs, water harvesting
EuroBent™ vs Traditional Clay Liners
