BentoSure® GCL

BentoSure GCL is a needle punched, reinforced barrier system that combines two durable geotextile outer layers and a core of high swelling sodium bentonite clay. This forms a uniform, multidirectional, shear resistant hydraulic barrier with self-sealing characteristics. BentoSure can also be supplied with a polymeric membrane attached for additional performance benefits.

Manufactured from strong and durable geotextiles in combination with fine granular sodium bentonite, ensuring the long term performance of the liner. When hydrated, the bentonite swells to form a low permeability layer with the equivalent hydraulic protection of a thick compacted clay layer.
