1. Mining Industry
Tailings Dams & Leach Pads - Prevents toxic seepage and ensures environmental compliance.
Heap Leach Pads - Offers chemical resistance against acidic/alkaline solutions.
Washing Pools - Provides a durable, impermeable barrier for mineral processing.
2. Water & Liquid Containment
Floating Covers - Reduces evaporation and contamination in reservoirs/pits.
Potable Water Liners - Safe for drinking water storage (certified for non-toxicity).
Wastewater Lagoons - Blocks pollutants from infiltrating groundwater.
3. Waste Management
Landfill Liners & Caps - Secures hazardous leachate in municipal/industrial landfills.
Leachate Ponds - High puncture resistance for long-term containment.
4. Infrastructure & Civil EngineeringTunnel Waterproofing - Textured surface enhances friction for slope/stability.
Canals & Irrigation - Smooth surface optimizes flow efficiency.
5. Aquaculture & Agriculture
Fish Pond Liners - Non-toxic and UV-resistant for sustainable farming.
Decorative Water Features - Flexible installation for landscaping projects.



Exceptional Durability
Resists punctures, tears, and UV degradation for long-term performance (service life: 20+ years).
Stable in extreme temperatures (-70°C to +80°C).
Chemical & Environmental Resistance
Impermeable to acids, alkalis, and hydrocarbons (compatible with leachate, brine, and wastewater).
NSF-certified options available for potable water contact.
Customizable SurfacesSmooth Surface: Ideal for fluid flow (e.g., canals, floating covers).
Textured Surface: Enhanced friction for slope stability (e.g., landfill caps, tunnel linings).


Easy Installation
Lightweight yet robust; compatible with welding (dual-hot wedge, extrusion) and anchoring systems.
Superior Hydraulic Performance
Extremely low permeability (≤1×10-13 cm/s) ensures zero leakage, ideal for sensitive environmental containment.
Advanced Stress Resistance
High tensile strength (up to 40 MPa) and elongation at break (≥700%) to withstand ground settlement and dynamic loads.
Eco-Friendly & Non-Toxic
Free of heavy metals, phthalates, and volatile organics (VOC-free), safe for aquatic life and drinking water storage.
Cost-Effective Lifecycle
Low maintenance requirements and 50+ year design life reduce total ownership costs vs. traditional materials (e.g., clay or PVC).
