Introduction: Waterproofing Simplified, Performance Maximized
BentoSeal NB Sodium Bentonite Waterproofing Blanket represents a breakthrough in geosynthetic technology, combining natural sodium bentonite with advanced carrier geotextiles to create an intelligent, self-sealing barrier system. This innovative solution delivers unmatched waterproofing performance while significantly reducing installation time and costs compared to traditional methods.
What Makes BentoSeal NB Unique?
Our waterproof blanket features a precisely engineered layer of high-quality sodium bentonite encapsulated between two robust geotextile layers. When hydrated, the bentonite swells to form a continuous, low-permeability gel barrier that automatically seals punctures and seams. This unique self-healing capability ensures long-term reliability even in demanding conditions.
Key Product Advantages:
Superior Waterproofing Performance
Achieves permeability coefficients as low as 5×10⁻¹¹ m/s
Withstands hydrostatic pressures exceeding 1.0 MPa
Provides waterproofing equivalent to 1 meter of compacted clay in just 6mm thickness
Exceptional Self-Healing Capability
Automatically seals cracks and punctures up to 2mm wide
Maintains integrity even under structural movement
Self-sealing properties remain effective throughout the product's lifespan
Rapid Installation & Cost Efficiency
Simple roll-out installation requires no specialized equipment
Reduces installation time by up to 50% compared to conventional methods
