Long-Lasting Waterproof Performance Sodium Bentonite Geosynthetic Clay Liner for Environmental Projects

Product Introduction

Sodium-based bentonite waterproof blanket is a new type of geosynthetic material mainly composed of sodium-based bentonite particles and geotechnical fabric through specific processes. Sodium-based bentonite, also known as sodium-based montmorillonite, can swell more than 24 times when it comes into contact with water and forms a stable colloidal waterproof layer through needling technology. Due to its unique waterproof properties, this material has been widely used in various fields.

Product Properties

Sodium-based bentonite waterproof blankets have the following performance characteristics:

Swelling in Water: Sodium bentonite expands when it comes into contact with water, forming a uniform colloidal system with high viscosity and low filtrate loss, thereby exhibiting waterproof properties.

• Durable Waterproof Performance: Due to its unique waterproof mechanism, sodium-based bentonite waterproof blankets can provide long-lasting waterproof effects.

• Environmentally friendly: As a natural and environmentally friendly impervious material, sodium bentonite waterproof blankets do not pollute the environment after use.

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.
