Bentonite Geosynthetic Clay Liner The Best Geosynthetic Material for Seepage Prevention in Environmental Engineering
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.
Density: Sodium-based bentonite forms a high-density diaphragm under water pressure, exhibiting an extremely strong self-water retention property.
Permanent Waterproofing: Sodium bentonite is a natural inorganic material that does not age or corrode due to the passage of time or changes in the environment.
Easy Construction and Short Duration: Compared to other waterproof materials, the construction of bentonite waterproof blankets is relatively simple, requiring no heating or adhesion, and is convenient for maintenance.
Temperature-independent: Bentonite waterproofing blankets maintain good waterproofing properties even in cold conditions.
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.
To sum up, bentonite waterproof blankets are an efficient, durable, and easy-to-construct material for preventing leakage, suitable for a variety of engineering fields.
