Bentoshield PE - Chemical-Resistant Geosynthetic Clay Liner
Bentoshield TH
Bentoshield PE is the polymer-enhanced version of standard Bentoshield. Polymer-modified sodium bentonite granules are mechanically bonded between woven and nonwoven geotextile layers. Standard sodium bentonite can lose swelling capacity - and with it, hydraulic performance - in high-ion-concentration environments such as saline water or heavy-metal-bearing leachate. Polymer modification slows this cation-exchange degradation, preserving long-term impermeability in chemically aggressive conditions.
Bentoshield PE Functions
Once hydrated, BentoShield PE swells to form an effective hydraulic barrier that is impermeable to liquids, water vapor, and gases. Compared to the meters of compacted clay soil used in storage areas, BentoShield PE provides superior hydraulic performance with a thickness of less than one centimeter.
Leak-proof
The swelling bentonite forms a low-permeability barrier that prevents the passage of liquids and gases.
Protection
It provides reliable protection for structures by maintaining low permeability under aggressive chemical conditions.
Reinforcement
Prevents intermixing of adjacent soil or fill layers.
Separation
It prevents intermixing between different materials, maintaining structural stability and long-term performance.
Polymer-modified Geosynthetic Clay Liner (GCL)
Thanks to the polymer-modified sodium bentonite granules in its Bentoshield PE structure, it effectively creates an impermeable layer even in areas with highly hazardous chemical leaks, protecting our soil, our living spaces.
Bentoshield PE Features
- High liquid impermeability under hazardous chemicals
- Unique self-healing capability
- Provides effective protection under high pressures
- BentoShield: 2x10⁻¹¹ m/s impermeability, superior leakproofing compared to a 1m clay layer
- Polymer-modified sodium bentonite granules
- BentoShield: No welding or stitching required; apply by overlapping the connection points
- It prevents hazardous wastewater from mixing with nature by being used in mining waste storage areas.
- BentoShield creates an environmentally friendly structure by preventing leachate from leaking into the soil at landfill sites.
Bentoshield PE Applications
- Mining sites and tailings dams (high mineral-content leachate)
- Industrial waste containment facilities
- Solid waste sites with aggressive chemical leachate risk
- Contaminated land isolation projects
