Eurobent GCL CS – HDPE-Coated Geosynthetic Clay Liners
HDPE-Laminated Composite GCL Barriers For Critical Containment Systems Across Africa
At Geosynthetics Africa, we supply and install certified Eurobent GCL CS HDPE-coated geosynthetic clay liners engineered for high-performance containment, waterproofing, and environmental protection in mining, landfill, infrastructure, and industrial projects.
Designed as an advanced composite barrier liner system, Eurobent GCL CS integrates reinforced needle-punched sodium bentonite with a thermally bonded HDPE geomembrane backing. This dual-layer configuration delivers enhanced sealing performance by combining the ultra-low permeability of bentonite with the impermeability, durability, and chemical resistance of an HDPE geomembrane — ideal for critical containment applications including tailings facilities, hazardous waste cells, tunnels, reservoirs, and foundation works
Also referred to as composite GCL liners or geomembrane-backed bentonite liners, HDPE-coated GCL systems provide enhanced barrier performance for critical containment infrastructure.
Why Choose Eurobent GCL CS?
Dual Sealing System – HDPE geomembrane + bentonite core
Thermally Locked Bond – prevents delamination
High Puncture Resistance – reinforced structure resists mechanical stress
Self-Sealing Capability – natural sodium bentonite swells to seal punctures
Excellent Chemical Resistance – suitable for aggressive leachates
Fast & Easy Installation – reduces labour and overlap time compared to traditional CCLs
Product Structure
Eurobent GCL CS consists of:
Upper layer: High-strength woven geotextile
Core: Natural sodium bentonite with high swell index
Lower layer: Nonwoven geotextile
Laminated barrier: HDPE, LLDPE or PVC geomembrane, thermally bonded to the nonwoven side
📌 The geomembrane layer enhances the GCL’s barrier properties while protecting the bentonite from desiccation, chemical attack, and root intrusion.
