Product Description
Bentonite Geosynthetic Clay Liner for River and Lake Seepage Prevention
Sodium bentonite waterproof blanket (GCL) is an efficient and environmentally friendly waterproof material widely used in various engineering applications. When exposed to water, sodium bentonite absorbs five times its own weight and expands to 15-17 times its original volume, forming a high-density impermeable barrier with excellent self-water retention properties.
Key Product Properties
- Superior Waterproof Performance: Excellent impermeable properties for reliable seepage prevention
- Environmental Safety: Non-toxic and harmless to humans, environmentally friendly with excellent ecological compatibility
- Easy Installation: Simple construction process requiring only bentonite powder, nails, and washers for connection and fixation
- Long-Term Durability: Natural inorganic material that resists aging reactions for extended service life
Application Areas
- Municipal Engineering: Subways, building underground works, and roof reservoir seepage prevention
- Environmental Protection: Landfills, sewage treatment sites, and industrial waste seepage control
- Water Conservancy Projects: River, lake and reservoir dam seepage prevention, plugging, and reinforcement
- Landscape Architecture: Artificial lakes, golf course ponds, and water feature seepage prevention
- Industrial Applications: Petrochemical, mining, agriculture, and other engineering fields requiring seepage prevention, corrosion protection, and reinforcement
