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.
