Self-Healing Waterproofing
Natural sodium bentonite core swells up to 15X its dry volume when hydrated, automatically sealing punctures
Forms a low-permeability gel (<5×10⁻¹¹ m/s) upon contact with water
Exceptional Durability
Non-degradable bentonite maintains performance for 100+ years
Resists freeze-thaw cycles and UV exposure when properly covered
Installation Efficiency
Lightweight rolls (5-7kg/m²) enable 3X faster installation vs compacted clay
No special equipment required – deploys like standard geotextile
Overlaps self-seal without additional treatment
Introduction:
The Bentonite Waterproofing Blanket (GCL) is a high-performance geosynthetic clay liner that combines natural sodium bentonite with reinforced geotextiles to create an exceptionally effective waterproofing system. This Bentonite Waterproofing Blanket is engineered to provide automatic self-sealing capabilities, making it ideal for containment applications where reliable, long-term hydraulic performance is critical.
Key Features
1. Self-Sealing Technology:
The Bentonite Waterproofing Blanket contains high-quality sodium bentonite, which swells up to 15 times its original volume when exposed to water, forming a low-permeability gel layer (≤5×10⁻¹¹ m/s).
Even if punctured, the Bentonite Waterproofing Blanket can self-repair, ensuring continuous waterproofing protection.
2. Superior Hydraulic Performance:
The Bentonite Waterproofing Blanket achieves hydraulic conductivity of <5×10⁻¹¹ m/s, outperforming traditional compacted clay liners.
Its bentonite core remains stable in pH 4-13 environments, resisting chemical degradation.
3. Easy Installation & Cost Savings:
The Bentonite Waterproofing Blanket is supplied in pre-fabricated rolls, allowing for quick deployment—up to 3X faster than clay liner installation.
Unlike rigid barriers, the Bentonite Waterproofing Blanket conforms to uneven surfaces, reducing the need for extensive subgrade preparation.
4. Durable & Environmentally Safe:
The Bentonite Waterproofing Blanket is non-toxic, making it safe for potable water applications.
It resists freeze-thaw cycles and UV exposure when covered, ensuring 100+ years of service life.
