What is the ISOBENT ( GCL)?
This product includes 2 layers of geo-textiles (woven and non-woven) with grained sodium bentonite in between. The nonwoven textile is locked to the woven textile through the sodium bentonite using needling. This way, a composite is formed as a perfect layer to stop transferring fluids. ISOBENT is produced in the form of rolls with different length and width.
How ISOBENT WORKS?
Sodium Bentonite is a Solid material from the Clay category which is formed from volcano activities during 16 millions of years. This material will swell rapidly and forms a gelatin type of state if exposed to a fluid and stops gases and liquids from getting through it. This formed gelatin type of material is sandwiched between two layers of textiles and forms a sealing film with the thickness of 6 millimeters.
There is a unique specification in ISOBENT highlighting it from other products which is its self-curing specification. In other words, ISOBENT will cure itself in case it gets damaged during installation or thereafter.
Why using ISOBENT
A) - Protection of environment
In order to avoid from pollution of soil, surface water and underground water, it is essential that polluted materials to be surrounded and conducted by means of protecting layers. It is recommended to use ISOBENT in the following cases:
- Mine heaps and tailing dams
- Landfills ( sanitary garbage dumping cells )
- Wastewater lagoons
- Tank farms in oil projects
- Waste materials resulted from drilling of oil wells
B) Water sealing
Dams and lake of dams
Water transferring channels
Artificial lakes
Agricultural water storage pools
Shrimp and fish pools
Tunnels
Road making
Underground structures
Deep foundation
C) Agriculture
ISOBENT keeps water inside itself and it will stop water from wasting as well. Besides, the possibility of growing roots of plants inside ISOBENT can give a special advantage to this product. In arid and dry areas in which sandy soils and plants need a permanent moisture, the ISOBENT has a high usage .
