Granular Bentonite Introduction
Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite. The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al). Our company mainly provide natural sodium bentonite.
Sodium bentonite expands when wet, absorbing as much as several times its dry mass in water. The property of swelling makes sodium bentonite useful as a sealant, since it provides a self-sealing, low permeability barrier. It is used to line the base of landfills, for example.
Our company uses natural sodium bentonite granular as sandwiched, nonwoven/woven geotextile as cap layer and carrier layer to needle punch together in order to produce a composite liner to be applied as a waterproofing barrier.

Application
The property of swelling on contact with water makes sodium bentonite useful as a sealant, since it provides a self-sealing, low-permeability barrier.
It is used to line the base of landfills to prevent migration of leachate, for quarantining metal pollutants of groundwater, and for the sealing of subsurface disposal systems for spent nuclear fuel. Similar uses include making slurry walls, waterproofing of below-grade walls, and forming other impermeable barriers, e.g., to seal off the annulus of a water well, to plug old wells.
So its application can be expanded to many industries including subway, tunnel, artificial lake, landfill, airport, hydraulic engineering, bridges and roads, building, etc.
