Bentonite Waterproof Blanket For Seepage Prevention Of Artificial Lake
Product Introduction
Sodium bentonite waterproof blanket is a new type of geosynthetic material, which is widely used in various seepage prevention projects. It is made of graded natural sodium bentonite particles and corresponding admixtures mixed as raw materials, and the bentonite particles are fixed between geotextile and plastic woven cloth by acupuncture process and equipment.
Product Properties
1. Excellent impermeability: Sodium bentonite has the property of swelling in contact with water.
2. Environmental protection and durability: Because sodium bentonite is a natural inorganic material, even after a long time or changes in the surrounding environment, there will be no aging or corrosion phenomenon, so the waterproof performance is durable.
3. Simple construction: Sodium bentonite waterproof blanket is easy to operate, short construction period, can adapt to the uneven settlement of the foundation, and has a good healing ability for cracks and other defects.
Product Application
1. Landfill: As the basic treatment and capping material of landfill, sodium bentonite waterproof blanket is widely used in many developed countries or regions at home and abroad, such as the United States, South Korea, Germany and other countries in the landfill impermeable layer.
2. Water conservancy projects: In water conservancy projects, sodium bentonite waterproof blankets are used for anti-seepage treatment of reservoirs, channels, rivers, etc.
3. Municipal engineering: In municipal construction, sodium bentonite waterproof blanket can be used for seepage prevention of underground garages, roof gardens, artificial lakes, pools and other projects.
4. Traffic engineering: In rail transit engineering, sodium bentonite waterproof blankets have also been applied to ensure the waterproof performance of underground structures.
