Product Description
Product Description

This high sealing bentonite GCL liner is engineered for landfill containment systems where reliable leakage prevention is essential. It integrates sodium bentonite between two geotextile layers to form a durable composite barrier.

Upon hydration, the bentonite swells and fills voids within the structure, creating a dense and impermeable layer that blocks liquid migration. This sealing mechanism ensures long term protection even under pressure and harsh environmental conditions.

Compared with compacted clay liners, this product offers uniform quality, faster installation, and reduced construction costs. It also provides flexibility during installation, allowing it to conform to uneven landfill surfaces.

It is widely used in municipal waste landfills, hazardous waste containment, and environmental engineering projects requiring strict anti seepage performance.
