A Geosynthetic Clay Liner (GCL) is made up of two layers of geotextile with a layer of low-permeability sodium bentonite sandwiched in between. This design creates a strong, waterproof barrier that effectively blocks water from seeping through.
PENNLINER is a kind of geosynthetics used in artificial lake water, landfill, underground garage, roof garden, pool, oil depot and chemical yard, solving the problems of sealing, isolation and leakage prevention, and has good effect and strong destructive resistance.
There are two kinds Geosynthetic clay liner by category, needling type and film covered type.
1. Compactness.
2. Permanent waterproof performance.
3. Easy construction.
4. Not affected by temperature.
5. Integration of waterproof materials and objects.
6. Green and environmentally friendly.
