ELCOSEAL® Geosythetic clay liners ( GCLs )
LCOSEAL Geosynthetic Clay Liners (GCLs) are used as an easy to install lining system in landfills and waste containment structures and for liquid containment in effluent ponds and tailings dams. ELCOSEAL GCLs are also effective liners for dams, ponds, lakes, wetlands, irrigation canals and channels.
ELCOSEAL GCLs consist of a layer of bentonite bonded between two layers of woven and nonwoven geotextiles. The needle-punching process reinforces the bentonite layer with thousands of fibres, maximising the product’s internal resistance. An additional heat treating process called “thermal locking” secures the needle-punched fibres, further improving strength and performance.
Function
ELCOSEAL GCLs have been used in environmental, civil and landfill liner applications since 1996. They have an unmatched sealing capability and are cheaper to install than natural clay layers. When hydrated, the sodium bentonite layer forms a barrier that prevents contamination of surrounding groundwater.
ELCOSEAL GCLs can replace thick, compacted clay layers in composite landfill liners and caps, thanks to the fast swelling sodium bentonite clay liner. This creates a highly effective containment barrier for landfill final cover systems and base landfill liner systems. ELCOSEAL GCLs can self-heal around holes or punctures so there is less chance of leaks due to installation damage.
Applications
Landfill
Landfill lining and capping systems reduce leakage of leachate out of the landfill waste body and prevent water infiltration through the top surface of the landfill. ELCOSEAL GCLs can be used in landfill base liners, side slopes and caps to replace or supplement traditional lining systems.
Mining
ELCOSEAL GCLs allow tailing ponds and rehabilitation projects to be built faster and more cost-effectively. They reduce leakage of contaminant materials from the site and help mining companies achieve environmental compliance.
Liquid containment
GCLs have low permeability and high internal shear strength, making them ideal for liquid contain ment such as reservoirs, wetlands and irrigation canals, as well as effluent, industrial and landscaped ponds and lagoons.
Ponds & Dams
The low permeability, high internal shear strength and easy installation process enables ELCOSEAL GCLs to provide excellent liquid containment, such as in reservoirs, irrigation canals, as well as ponds and lagoons.
