 Mr Wang with customers from different countries

1.Introduction: 

Geosynthetic Clay Liners (GCLs) are hydraulic barriers made of clay bonded to a single geosynthetic layer or to multiple geosynthetic layers. Because of its low permeability, swelling capacity and relative abundance, natural sodium bentonite is the preferred clay component of GCLs.

A wide range of materials, including geotextiles and geomembranes, are used to carry and encapsulate the clay. Also, they provide the product with structural support.

GCLs are used primarily as substitutes for compacted clay liners (CCLs), providing significant advantages in cost, ease of installation, and performance.

2.Features: 

Self Healing with consistent thickness throughout provides a higher degree of confidence

Fast and easy to install

Low thickness

High shear strength due to the bentonite being captured within the needle-punched fibres

Uniform distribution of bentonite within the GCL is maintained throughout

The material is fully needle-punched composite which contains highest quality sodium bentonite between two layers of geotextile.

The purpose of the GCL is for the bentonite to swell when hydrated and form a natural hydraulic barrier

3.End Use Application:  

Surface Impoundment

Secondary Containment

Landfill

GCL for Construction and Real Estate
