Product Description
Product Overview
Sodium Bentonite Geosynthetic Clay Liner is an advanced environmental protection and ecological composite impermeable material. Its unique anti-seepage properties make it ideal for various engineering applications requiring reliable waterproofing solutions.
Key Properties
Manufactured from natural sodium bentonite (montmorillonite), this material expands more than 24 times when exposed to water, forming a uniform colloidal system with high viscosity and low filtration. As an inorganic natural material, it offers excellent durability without aging reactions and is completely environmentally safe.
Applications
- Municipal Engineering: Subways, building underground works, roof reservoir seepage prevention
- Environmental Protection: Landfill sites, sewage treatment facilities, industrial waste management
- Water Conservancy: Rivers, lakes, reservoirs for seepage prevention and reinforcement
- Landscaping: Artificial lakes, golf course ponds, garden water features
- Industrial Applications: Petrochemical, mining, agriculture for corrosion protection and leak prevention
