Bentonite Geosynthetic Clay Liner The Ultimate Geosynthetic Material for Seepage Prevention
Product Introduction
Geosynthetics Clay Liner(abbreviated as GCL) is a geosynthetic material specifically designed for preventing seepage. It mainly consists of high-swelling sodium-based bentonite filled between specially designed composite geotechnical fabrics and non-woven fabric, which are formed through needling. When exposed to water, this material can form a uniform, high-density gelatinous waterproof layer, effectively preventing water seepage.
Product Properties
1. High expansibility: sodium bentonite can absorb five times its
own weight in water, and the volume can expand to more than 15-17
times the original.
2. Low permeability: The formation of a high-density diaphragm
under water pressure, water permeability can reach 5×10^-11m/s,
with strong waterproof performance.
3. Durability: As a natural inorganic material, sodium bentonite
will not reduce performance due to aging or corrosion, and has
long-term durability.
4. Environmental protection: harmless to the human body, friendly
to the environment, is an environmentally friendly material.
5. Easy construction: no need to heat or paste, easy and fast
construction.
Product Application
Bentonite waterproof blankets are widely used in various environmental engineering applications, such as:
Man-made lake water scenery
Landfill
Underground Parking Garage
Rooftop Garden
Pool
Oil Depot
Chemical Warehouse
In addition, it is also used in water conservancy projects, highway projects and other projects that require waterproofing.
