Versatile Bentonite Geosynthetic Clay Liner For Various Waterproof
Needs
Product Introduction
Bentonite waterproof blanket is a new type of geosynthetic
material, which is widely used in various seepage prevention
projects. Its main component is high expansibility sodium
bentonite, which is made by fixing between two layers of geotextile
or woven cloth through a special needling process.
Product Properties
1. Excellent waterproof performance: sodium bentonite has a very
high self-water retention performance, and can rapidly expand to
form a dense diaphragm after encountering water, effectively
preventing groundwater penetration.
2. Good durability: Because bentonite is a natural inorganic
material, it will not suffer from aging or corrosion, so its
waterproof performance is durable.
3. Environmental protection: Bentonite is a natural material,
harmless to the human body and the environment, and belongs to
green environmental protection materials.
4. Simple construction: Bentonite waterproof blanket construction
process is simple and fast, suitable for a variety of complex
terrain and environmental conditions under the waterproof project.
Product Application
1. Artificial lakes and water features: prevent water leakage and
maintain water quality.
2. Landfill: prevent leachate leakage and protect the environment.
3. Underground garage and roof garden: prevent rainwater
infiltration and protect the building structure.
4. Oil depots and chemical dumps: prevent chemical leaks from
polluting the environment.
