Customized Bentonite Geosynthetic Clay Liner For Seepage Control In Reservoirs And DAMS
Product Introduction
Sodium bentonite waterproof blanket (GCL) is a kind of waterproof and impermeable material with high performance. It utilizes the natural swelling property of sodium bentonite to achieve waterproof effect.
Product Properties
1. High expansibility: sodium bentonite can expand significantly when exposed to water, forming a gel-like waterproof layer.
2. Low permeability: It has very low permeability to ensure excellent water resistance.
3. Durability: As a natural inorganic material, it has good aging resistance and chemical corrosion resistance.
4. Environmental protection: Made of natural bentonite, non-toxic and harmless, friendly to the environment.
Simple construction: The construction process is simple, does not require special equipment, easy to operate.
Product Application
1. Landfill: Used for basic treatment and capping to prevent the infiltration of pollutants.
2. Water conservancy project: used as a waterproof layer in reservoirs, DAMS, rivers and other projects.
3. Subways and tunnels: used for waterproofing underground works to improve the durability of structures.
4. Basement and roof garden: Prevent leakage and retain moisture in the building area.
5. Artificial lake and landscape engineering: used for waterscape engineering seepage prevention, maintain water quality and water stability.
