A geosynthetic clay liner (GCL) is comprised of two geotextiles that are needlepunched together, encapsulating a layer of sodium bentonite clay between them. GCLs are known for having consistent, very low permeability. They have the unique ability to seal around penetrations, self-heal punctures, and self-seam at the overlaps.

Get PriceBentofix® geosynthetic clay liner (GCL) outperform significantly thicker layers of compacted clay. The exceptional, immediate swelling characteristic of powdered sodium bentonite provides a long-term barrier that can “self-seal and re-heal” (e.g., swell to fill potential punctured/damaged zones) and rehydrate to renew the barrier even if it has been exposed to desiccation.
Get PriceLining farm dams with Geosynthetic Clay Liners is very cost effective because it can be done with basic farm machinery. Unlike HDPE membranes, clay liners do not require specialised equipment to weld the joins. Before laying the GCL, the surface must be well prepared. A heavy roller then compacts and smooths the soil.
