Geosynthetic Clay Liner – Containment

Bentoliner GCL - Geosynthetic Clay Liner

Geosynthetic Clay Liner – Containment

Bentoliner GCL is a reinforced Geosynthetic Clay Liner composite, consisting of a layer of sodium bentonite granules encapsulated by layers of durable geotextiles and shear reinforced by needle punching together all components.

The material is typically anchored in a trench around the perimeter of a containment basin to provide the required pullout resistance. Bentoliner GCL should be placed in the trench extending down the inside wall face and along the entire trench floor, secured by the controlled placement and compaction of backfill into the trench prior to placing cover soil on the slopes.

The Bentoliner GCL is ideal for containment applications and provides a cost-effective engineered solution for clients and consultants. It is well proven to save money against  natural clay liner options.

THE BENEFITS OF GCLs

  • Has been used world-wide for more than 20 years
  • When the sodium bentonite is hydrated under confinement, it swells to form a low permeability layer
  • Alternative to compacted clay liners (CCL) and plastic liners

IDEAL USAGE

  • Ponds
  • Dams and dam wall liner
  • Containment areas
  • Cut-off walls
