Waterproof Bentonite Geosynthetic Clay Liner For Reservoirs And Channels
Product Introduction
Sodium bentonite waterproof blanket (GCL) is a new type of geosynthetic material, which is widely used in various seepage prevention projects. Its main components are graded natural sodium bentonite particles and corresponding admixtures, which are made by fixing the bentonite particles between two layers of geotextile and plastic woven cloth by needling process.
Product Properties
1. Excellent waterproof performance: Sodium bentonite will be highly expanded after water, forming a gel-like impermeable body, with high self-water retention performance.
2. Good durability: Because bentonite is a natural inorganic material, it will not occur aging reaction or corrosion phenomenon, so it has a long-term waterproof effect.
3. Simple construction: sodium bentonite waterproof blanket construction operation is simple, short construction period, suitable for a variety of complex environment waterproof project.
4. Environmental protection: As a green material, sodium bentonite waterproof blanket does not contain toxic and harmful substances, and is friendly to the environment.
5. High deformation resistance: It has good overall stability and deformation resistance, and can effectively cope with changes in various geological conditions.
Product Application
1. Water conservancy and environmental engineering: used for anti-seepage treatment of landfill, artificial lakes, reservoirs, channels, rivers, etc.
2. Traffic and infrastructure construction: used in subway tunnels, underground passages, basements, roof gardens and other underground buildings seepage prevention.
3. Municipal construction: It is also widely used in municipal projects such as sponge city construction, river and lake ecological protection and restoration.
4. Industrial applications: Used in chemical yards, oil depots and other places that need to prevent leakage.
