GCL – Geosynthetic Clay Liner is a woven fabric like material sandwich with bentonite clay in the middle. When installed correctly it behaves like a geomembrane, resulting lower permeability slowing down any seepage out of the dam. Due to bentonite clay having a very low hydraulic conductivity it makes for an effective GCL.
A typical GCL roll construction would consist of two layers of geotextile stitched together enclosing a layer of processed sodium bentonite. Approximate thickness of GCL is 6mm.
GCL is predominately used in landfills as a backup to a geomembrane layer.
Engineering wise, GCL is containment as a hydraulic barrier to water, leachate or other liquids. GCL is used as a replacement for compacted clay liners in landfill cells and capping. For best practise liner security, a three component composite of compacted clay liner/ GCL and Geomembrane can be used.
1, bentonite waterproof geosynthetic clay liners construction, foundation should be checked and inspected, the foundation should be rammed flat, no potholes and water, no gravels, no roots and other sharp objects.
2, bentonite waterproof geosynthetic clay liners in the process of handling and construction should be to avoid vibration and impact, to avoid the blanket body having a large degree of bending.
3. After the installing and acceptance of GCL, backfill shall be carried out as soon as possible. If it is in conjunction with the use of HDPE geomembrane, which shall be installed and welded in time to prevent it from being wet or broken by rain.
