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:
In addition, it is also used in water conservancy projects, highway projects and other projects that require waterproofing.
