GCL
GCL is usually Geosynthetic Clay Liner. YR GCL Manufacturer from China, Supplier offers a range of high quality GCL.Here is its detailed introduction:
Description
GCL is a new type of geosynthetic material, which is mainly composed of bentonite particles and geotextiles or geomembranes. Bentonite is a clay mineral with montmorillonite as the main component, which has the characteristic of swelling when it comes into contact with water. Its structure is generally to sandwich bentonite particles between two layers of geotextiles or geomembranes, and make them into a whole through processes such as needle punching and suturing.

GCL Features
Excellent waterproof performance:
GCL will expand rapidly when it comes into contact with water, forming a dense and impermeable gel layer with an extremely low permeability coefficient, which can effectively prevent water penetration. For example, in some water conservancy projects, it can well prevent leakage of water bodies such as reservoirs and pools.
Self-healing:
Even when the waterproof layer is punctured or partially damaged to a certain extent, the GCL particles can move to the damaged area after coming into contact with water and fill the pores, repairing the waterproof layer by themselves, and ensuring the continuity of the waterproof effect.
Good aging resistance:
Since its main component, bentonite, is a natural mineral with stable chemical properties, and the outer geotextile or geomembrane has a protective effect on it, it can resist the influence of environmental factors such as ultraviolet rays and temperature changes during long-term use, and is not easy to age and damage.
Simple construction:
It can be laid like a roll material, has strong adaptability to the construction site, does not require complex construction equipment and technology, can be constructed under various terrains and environmental conditions, and has a fast construction speed, which can effectively shorten the construction period.
Scope of application of GCL
– Water conservancy projects:
commonly used in anti-seepage treatment of reservoirs, dams, artificial lakes, channels, etc., to prevent water leakage and ensure the normal operation of water conservancy facilities.
Landfill:
As an anti-seepage material for the bottom and side walls of the landfill, it prevents the leachate from polluting the groundwater and the surrounding soil environment.
Underground engineering:
It is used in the waterproof construction of underground buildings such as basements, subways, tunnels, etc. to protect underground structures from groundwater erosion.
Roof waterproofing:
In the roof waterproofing projects of some buildings, bentonite waterproof blankets can also be used to provide a reliable waterproof barrier.
