Resistant to natural weathering, compression, and settlement.

Maintains integrity under heavy loads and over extended periods, ensuring a reliable long-term solution.

The bentomat geosynthetic clay liner material adapts to ground movements without cracking, making it suitable for sites with differential settlement.

Its long-term durability reduces the need for frequent replacements, lowering maintenance costs for landfill operators.

1.3 Environmentally Safe

Made from natural, non-toxic clay materials.

Provides a sustainable solution by minimizing environmental contamination and protecting local ecosystems.

Because the clay is sourced from natural deposits, it has no harmful chemical ingredients and poses zero risk to water or soil quality.

Its natural composition makes it compatible with eco-friendly landfill designs focused on long-term environmental stewardship.

1.4 Customizable Thickness and Compaction

Available in various thicknesses depending on project requirements, typically ranging from 300mm to 600mm or more.

Compaction standards can be tailored to meet local regulatory guidelines or specific landfill designs.

Engineers can adjust moisture content and compaction energy to achieve the exact permeability and strength required for the project.

This flexibility allows the bentomat clay liner to perform effectively across diverse climates, soil types, and waste load conditions.

1.5 Easy Integration with Other Liners

Can be combined with geomembranes or geosynthetic clay liners (GCL) for double-layer protection.

Supports composite liner systems for enhanced safety in high-risk landfills.

The clay layer forms a stable foundation for geomembranes, reducing the risk of punctures and enhancing the performance of the entire system.

When used as part of a multilayer barrier, the geo clay liner significantly improves overall containment efficiency and long-term leakage control.
