Industrial Plastics is excited to announce that we will be adding geosynthetic clay liner, also known as GCL to our comprehensive Industraline geosynthetics range in the 4th quarter of 2021. This innovative product is a manufactured alternative to compacted clay liners (CCL’s) and consists of a layer of bentonite clay bound between two layers of geotextile.

Unlike compact clay liners, installation of GCL does not require clay and other earth minerals to be imported and compacted to form a barrier. The GCL arrives on site in rolls and can be conveniently rolled out with lifting machinery, saving the need for labour intensive earth moving operations. The GCL is easily joined with a small overlap between sheets, with the joints held in place with a layer of soil placed on top of the overlap to create an impermeable barrier. There is no need for welding or other complex joining methods.
