5000g geosynthetic clay liner mat for artificial lakes
Description:
GCLs are high performance environmental liners comprised of a layer of low-permeability sodium bentonite combined with geosynthetic carriers, such as
woven and/or nonwoven geotextiles, and in some cases polymer geomembranes.
GCLs have been proven to provide better engineered performance and durabilitythan several feet of compacted clay with a total composite thickness of less than one quarter of an inch.
Advantages:
- It was possible to order the exact length of liner required across the channel to be supplied on one roll. This eliminated the need to ‘cut and paste’ the liner.
- The material is suitable for sites where no clay source was available..
Features:
- Improved leakage performance
- Permanent waterproof performance
- Simple construction and short time limit for a project.
- Not influenced by air temperature.
- A kind of green material and good to environmental protection.
- More versatile than compacted clay
- Increased airspace and liner efficiency

Application:
GCL is the material of choice for primary or secondary containment in
composite landfill cells and closures, mining leach pads, tailing
impoundments and reclamations, and pools and lagoons.
