High-Performance Bentonite Geosynthetic Clay Liner For Environmental Engineering

Product Introduction

The characteristics of sodium bentonite waterproof blanket (GCL) are mainly reflected in its waterproof and impermeable ability, construction convenience and environmental adaptability.

Product Properties

1. Excellent waterproof performance: Sodium bentonite has a strong water absorption, can absorb water equivalent to several times its own weight, and expand to form a gel, effectively prevent water penetration.
2. Low permeability: The permeability coefficient of sodium bentonite waterproof blanket is very low, usually far below 1×10^-9 cm/s, which can provide long-term reliable waterproof effect.
3. Versatility: In addition to being waterproof and impermeable, the sodium-bentonite waterproof blanket can also be used as a geosynthetic material for other geoengineering applications such as reinforcement, isolation and filtration.
4. Economy: Compared with other waterproof materials, sodium bentonite waterproof blanket has a higher cost performance and can reduce engineering costs.

Product Application

1. Environmental engineering: Used for the basic treatment and capping of waste landfill, to solve the problem of sealing, isolation and leakage prevention, with good results and strong destructive resistance.
2. Water conservancy engineering: Used in underground reservoirs, channels, rivers and other projects, to provide waterproof and impermeable function, enhance the stability of the structure.
3. Civil engineering: Used as a waterproof layer in underground buildings such as basements, subways, tunnels, and underground passages to improve the durability and reliability of the project.
