    Geosynthetic Clay Liner

    Geofantex GCL is a Geosynthetic Clay Liner and represents one of the most modern geosynthetic products available today. Geofantex GCL is a triple-layer composite containment (waterproofing) system comprising two geotextiles sandwiching a layer of highly reactive sodium bentonite material. When this sodium bentonite comes into contact with water, it swells to form an impermeable layer, typically with similar permeability characteristics as a one metre compacted clay layer.
