Self-Repairing Mechanism - The sodium bentonite core rapidly hydrates upon contact with moisture, expanding up to 15 times its dry volume to seal punctures, cracks, or seam gaps.
Instant Leak Prevention - Unlike rigid liners, this active sealing eliminates the need for manual repairs in minor damages (<10mm).
Long-Term Reliability - Maintains sealing capacity even after multiple wet-dry cycles, critical for landfill caps & seasonal water storage.
Product Introduction:
A high-performance geocomposite liner combining a durable geomembrane (HDPE, PVC, or LLDPE) with a bentonite clay core. Designed for landfills, mining, and industrial containment, it offers puncture resistance, UV stability, and self-sealing properties. The membrane layer enhances hydraulic performance (≤1×10⁻¹² cm/s) while the bentonite provides automatic crack repair. Ideal for slopes, tunnels, and exposed applications.
Product Features:
1. Superior Crack-Bridging Capability – Adapts to substrate movements, preventing leakage even under stress.
2. Non-Toxic & Environmentally Safe – Free from harmful additives, making it suitable for potable water and ecological projects.
3. Exceptional Chemical Resistance – Withstands aggressive leachates, acids, and hydrocarbons without degradation.
4. Self-Healing Properties – Bentonite swells upon contact with water, sealing minor damages automatically.
5. High Tensile Strength – Reinforced for stability in high-load applications like landfill caps and pond liners.
Installation & Best Practices
1. Surface Preparation: Ensure subgrade is smooth, compacted, and free of sharp debris; Use a protective geotextile layer if substrate is rough.
2. Liner Deployment: Unroll liner smoothly, avoiding folds or wrinkles; Overlap seams by min. 300mm, seal with bentonite tape or adhesive
3. Anchoring & Covering: Secure edges with trench anchors or ballast; Cover with soil, gravel, or concrete for added protection
4. Quality Control: Conduct leak detection surveys (electrical or vacuum testing); Inspect seams & overlaps for integrity
