This GCL waterproof liner is widely used in underground construction and basement waterproofing systems. It provides a reliable anti seepage barrier that prevents groundwater infiltration.
Its flexible structure allows it to conform to complex surfaces, ensuring complete coverage. After hydration, the bentonite layer forms a dense seal that blocks water movement.
It is ideal for underground garages, foundation systems, and construction projects requiring long term waterproofing performance.
