Geosynthetic Clay Liner (GCL) – Production Introduction

Bentonite Geosynthetic Clay Liner (GCL) is a high-performance waterproofing and anti-seepage material made from premium sodium bentonite encapsulated between geotextiles or geomembranes. With exceptional swelling ability, self-sealing performance, low permeability, and easy installation, GCL is widely used in landfill liners, artificial lakes, canal lining, reservoirs, embankment reinforcement, subway tunnels, and mining heap-leach projects.​

Our automated production lines ensure uniform bentonite distribution, needle-punch reinforcement, and stable composite structure. This ensures higher shear strength, enhanced durability, and superior adaptability to engineering environments. Compared with traditional compacted clay liners, GCL is thinner, easier to transport, faster to install, and more cost-effective.​

If you are looking for a reliable, eco-friendly waterproofing solution, bentonite GCL provides long-term protection, improved installation efficiency, and reduced overall project costs.
