GCL (Geosynthetic Clay Liner)
Geosynthetic Clay Liners (GCLs) are geotextile and bentonite composites (typically sodium bentonite sandwiched between two layers of geotextile) engineered for a variety of environmental containment applications. The geotextiles offer a long-lasting resistance to physical or chemical break-down in harsh elements, while the bentonite’s high swelling capacity and low permeability provide an effective hydraulic seal.
GCLs provide an excellent alternative to conventional Compacted Clay Liners by replacing a thick section of compacted clay with a thin layer of pure sodium bentonite. Benefits include easy installation, better hydraulic performance, and resistance to varying weather conditions. GCLs also have unique self-sealing attributes, reducing the risk of failure due to adverse field and operating conditions.
GCL Applications Include:
- Landfill liners
- Landfill caps
- Secondary containment
- Mining
- Canals, stormwater impoundments, and wetlands
- Ponds
