BentoSure is a reinforced needle punched geosynthetic clay liner (GCL) which is made by encapsulating a layer of high quality sodium bentonite between two geotextiles.

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.

BentoSure is commonly used for water reservoirs, dams and river embankments, liquid wastes disposals sites, transfer stations, secondary containment, solid wastes storage and disposal sites where the high performance, guaranteed quality, and ease of installation make it an economical and environmentally responsible option.

Benefits & Features

  • Utilise the natural swelling properties of Sodium bentonite to provide a very low permeability
  • Reduce transport costs and emissions by reducing the cartage of clay to site
  • Robust polypropylene geotextile encapsulates and contains the bentonite
  • BentoSure can handle differential settlement better than compacted clay liners
  • High shear strength and interface friction angles from the needle punch process
  • Quick, easy and cost effective to install
  • Self seeming overlap technology
