Bentoshield
Bentoshield
Bentoshield is a geosynthetic clay liner (GCL) manufactured by mechanically needling high-swelling-performance sodium bentonite granules between two layers of high-strength geotextiles. When in contact with water, the bentonite swells and forms an impermeable barrier against liquids, water vapor, and gases. One truckload of Bentoshield provides coverage equivalent to approximately 150 truckloads of conventional compacted clay required to achieve the same level of sealing. This results in significant savings in transportation, labor, and installation time on site.
Bentoshield Functions
Once hydrated, BentoShield swells to form an effective hydraulic barrier that is impermeable to liquids, water vapor, and gases. With a thickness of less than one centimeter, it provides superior hydraulic performance compared to meters-thick layers of compacted clay used in landfills.
Leak-proof
The swelling bentonite forms a low-permeability barrier that prevents the passage of liquids and gases.
Protection
Protects the underlying and overlying layers against mechanical damage and environmental impacts.
Reinforcement
The geotextile layers provide additional reinforcement to ground stability.
Separation
Prevents the intermixing of different material layers (e.g., soil and fill materials).
Bentoshield Features
- Self-healing capability
- Provides effective protection under high pressures.
- One truckload of BentoShield can cover the area covered by 150 truckloads of clay.
- With a thickness of less than 1 centimeter, BentoShield provides a significant amount of additional volume in a standard storage area, equivalent to 1 meter of compressed clay.
- BentoShield provides impermeability at a value of 5x10⁻¹¹ m/sec, demonstrating superior leak-proof performance compared to a 1-meter-thick clay layer.
- The Bentoshield application does not require any sources or stitches; you can simply apply it by overlapping the connection points.
- In highway projects, it is used in the base layer of road fill, combining impermeability, reinforcement, and separation functions to extend the life of the road structure.
- In railway projects, it is used under the foundation to prevent water rising by capillary action from reaching the ballast material, thereby extending the structure's lifespan and contributing to the creation of a safe structure.
- It provides unique insulation by utilizing its leak-proof properties in reservoir and dam projects.
Bentoshield Applications
- Solid waste landfills
- Pond, dam, and artificial water channel waterproofing
- Mining sites
- Railway and highway infrastructure projects
- Building foundation waterproofing
Why Choose Bentoshield?
Compared to traditional clay liners, Bentoshield provides equivalent performance with a much thinner cross-section, enabling fast and easy installation without the need for special equipment or welding. The self-healing properties of bentonite make Bentoshield a reliable solution for general-purpose waterproofing projects. For chemically aggressive leakage environments, refer to Bentoshield PE, the polymer-modified version of the product.
