Sodium Bentonite GCL Liner for Artificial Lake Waterproofing and Water Containment Systems
This bentonite waterproof liner is designed for water containment and artificial lake construction projects. It uses natural sodium bentonite as the core sealing material, which expands upon hydration to form a dense impermeable layer.
The liner is encapsulated between geotextile layers that provide mechanical strength and ensure even distribution of the bentonite. This structure enhances durability while maintaining excellent flexibility.
It is widely used in artificial lakes, ponds, reservoirs, and landscape water features where reliable waterproofing is essential. The material ensures minimal leakage while supporting long term water retention.
Unlike traditional waterproofing systems, this liner offers a self sealing function that automatically repairs minor punctures or damage when exposed to water.
