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.
