Geosynthetic clay liner is a needle-punched non-woven impregnated membrane. The membrane structure comprises water absorbing and water swelling polymers. An optional one-side polyethylene film on top of the needle-punched non-woven membrane and the self-healing properties of the Taian Hongyuan Seal Waterproofing System ensure optimum performance for various water sealing applications.
Bentonite mats, also referred to as geosynthetic clay liners (GCLs), are geosynthetic barriers used for various sealing and waterproofing applications in underground Mining and Civil Engineering.

The application range of Bentonite Mats comprises waterproofing, gas sealing, and usage as a vapor barrier. Geosynthetic clay liners are a proven and versatile sealing system that has been used in many construction projects around the world.
