Bentonite Waterproof Blanket For Road Railway Roadbed Reinforcement
Bentonite Waterproof Blanket For Road Railway Roadbed Reinforcement And Waterproofing
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, and the bentonite particles are fixed between two layers of geotextile by a special process to make a blanket waterproof sheet.
Product Properties
1. Excellent anti-seepage performance: sodium bentonite can be highly expanded after water, forming a gel, with a strong anti-seepage ability
2. Simple construction: Because of the light weight and small size of the sodium bentonite waterproof blanket, the construction does not need large machinery and equipment, and can be completed manually, which greatly reduces the difficulty and cost of construction.
3. Strong durability: Sodium bentonite waterproof blanket not only has good waterproof performance, but also has high destructive resistance and durability, and can effectively resist the impact of water erosion and environmental factors.
Product Application
1. Environmental engineering: waterproofing and impermeability of landfills, sewage treatment plants, etc.
2. Water conservancy engineering: the waterproof layer of reservoirs, DAMS, river management and other projects.
3. Traffic engineering: roadbed reinforcement and waterproofing of roads and railways.
4. Construction: Waterproofing of basements, roof gardens, etc.
5. Garden landscape: seepage prevention of water feature projects such as artificial lakes and ponds.
