Geosynthetic Clay Liners (GCLs)
 |
 |
 |
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 durability than several feet of compacted clay with a total composite thickness of less than one quarter of an inch.
GSE GSLs offer these benefits to exceed your GCL expectations:
- Highest quality, pure, non-amended Wyoming grade sodium bentonite
- Scrim reinforced
- Needle-free product
- Highest internal shear strength product
- Proven GCL dimensional stability
- More versatile than compacted clay
- Easy Installation
- Optimum freight loadability
