Advanced Sealing Solutions for Railway Soil Structures Using Geosynthetic Clay Liners

In railway construction, ensuring effective sealing of soil structures is crucial for environmental protection and infrastructure longevity. Novura’s Bentofix® NSP 5400 DB geosynthetic clay liners (GCLs) offer a robust solution, combining two durable geotextile layers encapsulating high-swelling sodium bentonite powder. This composition provides a uniform, multi-directional, shear-resistant hydraulic barrier with self-sealing and re-healing properties. The needle-punched reinforcement, with over 2 million fibres per square metre, ensures excellent shear stress transfer and installation robustness. Bentofix® GCLs are particularly advantageous in areas requiring environmental protection, such as sealing deep drains in groundwater-sensitive zones. Their high swelling capacity ensures immediate sealing performance, while the durable geotextile layers protect against installation damage, making them a reliable choice for enhancing the integrity of railway soil structures.
