Needle-punched GCLs with unrivalled sealing capability
ELCOSEAL® Geosynthetic Clay Liners (GCLs) are used as a lining system in landfills and waste containment structures, and for liquid containment in effluent ponds, wetlands and canals.
What are ELCOSEAL® Geosynthetic Clay Liners?
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.
Why choose ELCOSEAL® GCLs?
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.
How do I know if ELCOSEAL® GCLs are right for my project?
We provide a high level of technical support and research & development for designers and engineers together with specialist installation equipment. Contact us for technical or installation support or advice.
How it works?
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.
