GCL Bentonite Geosynthetic Clay Liner (3500–6000 g/m²)

Eurobent reinforced GCL satisfies EN 13493 for solid waste storage and disposal sites. As a base liner component, GCL provides the low-permeability clay barrier required by waste disposal regulations without clay borrow dependency or compaction programme risk. As a closure cap component, GCL provides the moisture barrier preventing rainwater infiltration into waste cells. CE marked. ITR documentation supplied with every roll for Environment Agency, DEA, and regulatory authority compliance on landfill projects across Africa.

Eurobent reinforced GCL is compliant with EN 13361 for reservoirs and dams. Installed on the upstream face of earth embankment dams and in reservoir base and side slope lining systems, GCL provides a permanent self-sealing hydraulic barrier replacing compacted clay puddle core or conventional clay lining. Used for irrigation reservoirs, potable water storage, industrial water supply dams, and agricultural water harvesting structures across Africa where compacted clay is unavailable locally or programme time is constrained

Eurobent reinforced GCL is compliant with EN 13362 for canal construction. Installed beneath concrete or aggregate canal lining, or used as a standalone barrier in low-velocity irrigation canals, GCL prevents seepage losses that account for 30 to 50% of delivered water in unlined canal systems. GCL canal lining is faster and more cost-effective than conventional concrete lining on canals with active clay subgrades or differential settlement risk - a common condition on African irrigation infrastructure.

Eurobent reinforced GCL compliant with EN 13492 for liquid waste disposal sites and secondary containment. Specified beneath fuel storage facilities, chemical storage bunds, transformer oil containment, and industrial process areas where secondary containment is required by regulation. The self-sealing bentonite provides redundancy that rigid concrete bund liners cannot match. Rapidly deployable on existing industrial sites with minimal civil disruption - a critical advantage on operational mine sites and industrial facilities.

Eurobent reinforced GCL is compliant with EN 15382 for transportation infrastructure. Used beneath road and railway embankments over contaminated ground to prevent upward migration of contaminants, as environmental protection under airports and logistics facilities on sensitive groundwater zones, and as a waterproofing barrier in below-ground civil structures. The self-sealing bentonite layer provides long-term barrier performance that synthetic membranes alone cannot guarantee under differential settlement conditions common in African road and rail embankment construction.

Eurobent 3500 is the entry grade with 3500 g/m2 net bentonite content and 5.8mm total thickness. Carrier layer 100 g/m2 PP woven, cover layer 200 g/m2 PP nonwoven. Permeability less than or equal to 5.0 x 10-11 m/s. Tensile strength MD 10.4 kN/m, CMD 8.5 kN/m. Peel strength 60 N/10cm. Roll format 5.1m x 40m - 204m2 per roll. Suited to secondary containment, stormwater retention ponds, and applications where a moderate bentonite mass satisfies the engineer or regulatory requirement. CE marked. EN 13361 and EN 13492 compliant.

Eurobent 4000 provides 4000 g/m2 net bentonite content and 6.6mm total thickness. Same permeability, tensile, CBR, and peel performance as all Eurobent grades. Roll format 5.1m x 40m - 204m2 per roll. Suited to irrigation reservoir lining, stormwater management ponds, environmental protection liners under infrastructure, and secondary containment for fuel and chemical storage. CE marked. Full EN harmonised technical specification compliance.

Eurobent 4500 provides 4500 g/m2 net bentonite content and 6.8mm total thickness. Standard mid-heavy specification for mining containment structures, tailings facility perimeter berms, small dam and weir sealing, canal lining, and applications requiring increased bentonite mass for higher hydraulic head or more chemically aggressive leachate. Roll format 5.1m x 40m - 204m2 per roll. CE marked. 25-year material warranty.

Eurobent 5000 is the primary specification grade for demanding African containment projects. 5000 g/m2 net bentonite, 7.4mm thickness, total GCL mass 5300 g/m2. Tensile MD 10.4 kN/m (-1kN/m), CMD 8.5 kN/m (-0.8kN/m). CBR puncture 1.8 kN (-0.18kN). Peel strength 60 N/10cm (-6N/10cm). Roll format 5.1m x 40m - 204m2 per roll. Specified for tailings storage facilities, landfill base liners, high-head reservoirs and dams, and primary containment for toxic and hazardous liquid waste. The most widely specified Eurobent grade on African mining and environmental projects. CE marked. 25-year warranty.

Eurobent 6000 is the highest bentonite content standard grade at 6000 g/m2 net bentonite and 7.8mm total thickness. Total GCL mass 6300 g/m2 (+-10%). Tensile MD 10.4 kN/m (-10%), CMD 8.5 kN/m (-10%). CBR puncture 1.8 kN (-10%). Peel strength 60 N/10cm (-10%). Roll format 5.1m x 35m - 178.5m2 per roll. Specified where maximum bentonite mass is required by the engineer or regulatory authority - primary liner systems for hazardous waste containment, high-head tailings facilities, and projects requiring maximum specification GCL as the secondary barrier behind a geomembrane primary liner. CE marked. 25-year warranty.
