Product Description

High quality bentonite waterproof pad(GCL)

Bentonite composite waterproof blanket (GCL) is a new type of geosynthetics. It is inflated by a natural sodium bentonite waterproof blanket spraying to protect the work surface above graded shotcrete waterproof blanket above the work surface protection bentonite particles and the corresponding mixing additives for raw materials, acupuncture technology and equipment, the bentonite particles fixed between the geotextile and plastic woven blanket made of waterproof membrane.

High quality bentonite waterproof  pad (GCL)Specification:

 

Unit weight≥4000g/sqm, width4m~6m

Made from two layers geotextile with natural sodium in the centre

 

Bentonite Geosynthetic Clay Liner :

 

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.

 High quality bentonite waterproof  pad (GCL) feature:

1)Improved leakage performance

2)Permanent waterproof performance

3)Simple construction and short time limit for project

4)Not influenced by air temperature

5)A kind of green material and good to environmental protection

6)More versatile than compacted clay

7)Increased airspace and liner efficiency

3.Usage:

1)Slope protection

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
