Heavy Duty Pond Liner Textured Geomembrane

Heavy Duty Pond Liner Textured Geomembrane is a high-strength polymeric impermeable liner with engineered surface texturing, designed to provide long-term seepage control and enhanced interface friction in ponds, reservoirs, and water containment systems under demanding engineering conditions.

Technical Parameters and Specifications

The following parameters represent commonly accepted industrial ranges for heavy-duty textured geomembranes used in engineered pond lining systems:

• Raw Material: HDPE or LLDPE resin (virgin or controlled blend)

• Nominal Thickness: 1.0 mm / 1.5 mm / 2.0 mm / 2.5 mm

• Density: ≥ 0.94 g/cm³ (HDPE)

• Tensile Strength at Yield: ≥ 15 MPa

• Elongation at Break: ≥ 700%

• Interface Friction Angle: 22°–30° (textured-to-soil)

• Carbon Black Content: 2.0–3.0%

• Oxidative Induction Time (OIT): ≥ 100 min (Std OIT)

• Service Temperature Range: -40°C to +60°C

Structure and Material Composition

Heavy Duty Pond Liner Textured Geomembrane typically adopts a monolithic structure with engineered surface profiling:

• Base Polymer Layer: High-density polyethylene matrix providing impermeability

• Textured Surface: Single-side or double-side asperities for friction enhancement

• Carbon Black Dispersion: UV resistance and long-term durability

• Thermal Stabilizers: Resistance to oxidative aging

Manufacturing Process

The production of Heavy Duty Pond Liner Textured Geomembrane follows an industrial extrusion-based workflow:

1. Resin drying and gravimetric batching

2. Flat-die or blown-film extrusion under controlled temperature profiles

3. Inline texturing using nitrogen injection or embossing rollers

4. Calendering and thickness calibration

5. Controlled cooling and stress relaxation

6. Automated winding and dimensional inspection

7. Laboratory testing (tensile, OIT, density, friction)

Key process controls include melt temperature stability, texture uniformity, and carbon black dispersion consistency.

Industry Comparison

Application Scenarios

Heavy Duty Pond Liner Textured Geomembrane is widely specified by:

• Distributors: Stocking standardized rolls for infrastructure projects

• EPC Contractors: Design-build water and environmental systems

• Engineering Firms: Slope stability–critical containment designs

Typical applications include irrigation reservoirs, aquaculture ponds, stormwater retention basins, leachate ponds, and industrial water containment.

Core Pain Points and Engineering Solutions

• Slope Instability: Textured surfaces increase interface friction

• Long-Term Leakage: High-density polymer ensures impermeability

• UV Degradation: Carbon black stabilization extends service life

• Thermal Cracking: Controlled resin formulation reduces stress cracking

Risk Warnings and Mitigation Recommendations

Improper use of Heavy Duty Pond Liner Textured Geomembrane may introduce risks:

• Over-texturing may complicate welding quality

• Incorrect thickness selection can lead to puncture risk

• Poor subgrade preparation increases stress concentration

Mitigation includes certified welding technicians, subgrade smoothing, and project-specific thickness calculations.

Procurement and Selection Guide

1. Define pond geometry and maximum slope angle

2. Confirm chemical exposure and temperature range

3. Select appropriate thickness based on load analysis

4. Specify single or double textured surface

5. Request compliance test reports (ASTM / ISO)

6. Evaluate roll dimensions and logistics efficiency

7. Assess supplier quality control and traceability

Engineering Case Application

In a 50,000 m² agricultural reservoir project, Heavy Duty Pond Liner Textured Geomembrane (1.5 mm, double-sided) was installed on 3H:1V slopes. Interface shear testing confirmed a friction angle exceeding 26°, enabling stable lining without anchor trench enlargement. Post-installation leak detection reported zero defects after commissioning.
