Excellent Chemical Resistance HDPE Smooth Geomembrane for Tailings Management 

Smooth Geomembrane for Tailings Management

Product Overview
Our smooth geomembrane is a robust, impermeable barrier engineered for tailings storage facilities (TSFs), mine waste containment, and industrial waste management. Crafted from high-density polyethylene (HDPE), this geomembrane delivers unmatched resistance to harsh chemicals, extreme environmental conditions, and mechanical stress, ensuring long-term containment of toxic materials and compliance with environmental regulations.

Key Features & Benefits

1. Superior Chemical Resistance

   • Hazardous Material Containment: Resists acids, alkalis, heavy metals, and leachates commonly found in mining and industrial waste.

   • Zero Permeability: Ultra-low permeability coefficient (<1×10⁻¹³ cm/s) prevents contaminant migration to soil and groundwater.

2. High Mechanical Strength

   • Puncture & Tear Resistance: Withstands pressure from sharp rocks, equipment, and settling tailings (Tensile Strength: ≥30 MPa).

   • Dimensional Stability: Maintains integrity under heavy loads and hydraulic stress.

3. UV & Temperature Resilience

   • Carbon-black stabilized for UV resistance, suitable for extreme temperatures (-50°C to +80°C) and prolonged outdoor exposure.

4. Environmental Compliance

   • Safeguards ecosystems by preventing toxic leakage, aligning with global mining sustainability standards.

   • Non-reactive and inert, ensuring no secondary contamination.

5. Cost-Effective & Durable

   • 30+ year service life reduces long-term replacement costs.

   • Compatible with geotextiles and drainage layers for composite liner systems.

Technical Specifications

Applications

• Tailings Dams & Ponds: Securely contain mining waste and prevent groundwater pollution.

• Heap Leach Pads: Resist corrosive chemicals in gold, copper, and uranium extraction.

• Industrial Waste Landfills: Line hazardous waste storage sites.

• Acid Rock Drainage (ARD) Control: Block sulfide oxidation and acidic runoff.

Installation Guidelines

1. Subgrade Preparation: Compact and level the base; remove protrusions; add protective geotextile if required.

2. Liner Deployment: Unroll geomembrane with minimal wrinkles; overlap seams by 10–15 cm.

3. Seam Welding: Use dual-track hot wedge welding or extrusion methods for leak-proof joints.

4. Anchoring & Covering: Secure edges in anchor trenches; cover with soil or ballast to prevent wind uplift.

5. Quality Assurance: Conduct electrical spark testing or vacuum tests to verify seam integrity.

FAQ
Q: Can it withstand acidic leachates from sulfidic tailings?
A: Yes, HDPE is highly resistant to pH extremes (pH 1–14) and corrosive chemicals.

Q: What thickness is recommended for high-pressure tailings dams?
A: 2.0mm–3.0mm, combined with geotextile protection, ensures optimal performance.

Q: Is it recyclable?
A: HDPE is 100% recyclable, supporting sustainable mine closure practices.
