Bentonite GCl Geosynthetic Clay Liner For Waterproof And Impermeable Needs

Product Description

Bentonite GCl Geosynthetic Clay Liner For Waterproof And Impermeable Needs

We, Changsha Jianyi, is a geosynthetic clay liner (gcl) manufacturer in China. Our GCL price is competitive in abroad and domestic market with good quality.

Geosynthetic Clay Liner introduction

It is betonite geo-synthetic waterproofing barrier. It is self-attaching and self -sealing to concrete or other construction structures. It is made of a non-woven geotextile, a natural sodic bentonite layer, with or without a pe geomembrane layer, and a polypropylene sheet.

These layers are connected with a dense felter that makes the bentonite a self-confinement with controlled expansion. With this system it is possible to avoid slippage and the accumulation of bentonite as a consequence of cuts, tears, vertical applications and movements.

Its performance can meet or exceed GRI-GCL3 and our national standard JG/T193-2006.

Geosynthetic Clay Liner product process:

Material Preparation
- Sodium bentonite (high-swelling clay) is purified and dried.
- Geotextile layers (woven/nonwoven polypropylene or polyester) are prepared.
Bentonite Spreading
- Bentonite powder (4.5–5 kg/m²) is evenly distributed between two geotextile layers.
Bonding Process
- Needle-punching: Fibers are mechanically entangled to hold bentonite in place.
- Stitching/Adhesive bonding (optional): Some GCLs use stitching or glue for extra strength.
Calendering (Optional)
- Rollers compress the blanket for better density and uniformity.
Quality Control
- Tests include peel strength, hydraulic conductivity, and bentonite distribution.
Cutting & Rolling
- The blanket is cut to size and rolled for packaging.

GCl Geosynthetic Clay Liner Function:

The engineering function of a GCL is containment as a hydraulic barrier to water, leachate or other liquids and sometimes gases.

As such, they are used as replacements for either compacted clay liners or geomembranes, or they are used in a composite manner to augment the more traditional liner materials.

The ultimate in liner security is probably a three component composite geomembrane/geosynthetic clay liner/compacted clay liner which has seen use as a landfill liner on many occasions.

Geosynthetic Clay Liner Application

1. Roadway separation and stabilization

2. Landfill leachate collection

3. Steepened slopes

4. Retaining walls

5. Embankments over soft soil

6. Lagoon closures

7. Silt fence

Geosynthetic Clay Liner Installation

1) Analyze the material cutting and draw the laying order and cutting diagram of bentonite waterproof blanket.

2) Check the surface quality of bentonite waterproof blanket and record the mechanical damage, manufacturing trauma, holes and other defects found to facilitate repair during laying.

3) The construction of waterproof blanket should be carried out in rainless and snowless weather. If it rains or snows during construction, use plastic film to cover it to prevent GCL from hydrating prematurely.
