Versatile Bentonite Geosynthetic Clay Liner For Waterproofing And Seepage Solutions
Product Introduction
Bentonite waterproof blanket (GCL) is an efficient waterproof
material, which is widely used in environmental engineering waste
landfill, underground reservoir, underground infrastructure
construction and other projects to solve the problem of sealing,
isolation and leakage prevention.
Product Properties
1. Waterproof performance: Bentonite waterproof blanket has
excellent waterproof and impermeable properties.
2. Durability: Since bentonite is a natural inorganic material, it
does not undergo aging reaction, so it has long-term durability.
3. Environmental protection: harmless to human body, non-toxic,
friendly to the environment.
4. Simple construction: no need to heat and paste, simple
construction and not limited by the construction environment
temperature.
Product Application
Bentonite waterproof blanket is suitable for a variety of projects,
including subway, tunnel, artificial lake, landfill, airport, water
conservancy, road and bridge, construction and other fields of
waterproof and anti-seepage projects.
