Elcoseal is a needle punched Geosynthetic Clay Liner (GCL) that consists of sodium bentonite powder embedded and sandwiched between two or more geotextiles. The sodium bentonite acts as the swelling and sealing component of the liner.

Elcoseal is typically used as base liner and final cover in landfills, Canal lining, effluent ponds, tank farms and cut off trenches.

Elcoseal can completely or partially replace thick, multi-lift compacted clay layers in composite landfill liners and caps due to the efficiency of the high swelling sodium bentonite clay.
