Customized Bentonite Geosynthetic Clay Liner for Impermeable Solutions in Different Construction Projects
Product Introduction
Bentonite Waterproof Blanket (Geosynthetics Clay Liner, abbreviated as GCL) is a geosynthetic material specifically designed for preventing seepage. It mainly consists of high-swelling sodium-based bentonite filled between specially designed composite geotechnical fabrics and non-woven fabric, which are formed through needling. When exposed to water, this material can form a uniform, high-density gelatinous waterproof layer, effectively preventing water seepage.
Product Properties
1. Waterproof performance: Bentonite waterproof blanket has excellent waterproof and impermeable properties.
2. Durability: Since bentonite is a natural inorganic material, it does not undergo aging reaction, so it has long-term durability.
3. Environmental protection: harmless to human body, non-toxic, friendly to the environment.
4. Simple construction: no need to heat and paste, simple construction and not limited by the construction environment temperature.
Product Application
Bentonite waterproof blankets are widely used in various environmental engineering applications, such as:
Man-made lake water scenery
Landfill
Underground Parking Garage
Rooftop Garden
Pool
Oil Depot
Chemical Warehouse
In addition, it is also used in water conservancy projects, highway projects and other projects that require waterproofing.
