Geomembran 500 micron (0.5 mm or 20 mil HDPE geomembrane) is a lightweight, flexible, and cost-effective impermeable liner widely used for moderate containment applications. With good chemical resistance, low permeability (≤1×10⁻¹¹ cm/s), tensile strength of 10–22 kN/m, puncture resistance of 200–350 N, and elongation ≥700%, these liners provide reliable seepage prevention (95–99%+) and service lives of 20–50+ years when properly protected.

This thickness is popular for aquaculture ponds, decorative water features, agricultural lagoons, secondary containment, irrigation ditches, and small reservoirs. It is easier to handle and install than thicker liners while offering better durability than thinner materials.

The global geomembranes market, valued at ~USD 2.0–2.8 billion and growing at 5–7% CAGR, favors 500 micron HDPE for budget-conscious and lighter-duty projects. This 2026 comprehensive review ranks the 7 best geomembran 500 micron, with detailed analysis of quantifiable metrics, technical specifications, real-world performance, and value. It features solutions from The Project Material Co., Ltd. (BPM Geosynthetics) alongside leading international manufacturers.

  • Puncture Resistance: 200–350 N (ASTM D4833)
  • Tear Resistance: ≥80–150 N
  • Oxidative Induction Time (OIT): ≥100 minutes
  • Carbon Black Content: 2–3%
  • Permeability: ≤1×10⁻¹¹ cm/s
  • Temperature Range: -40°C to +80°C+

Key Benefits:

  • Lightweight and easy to transport/install (reduces labor by 30–50% vs thicker liners).
  • Good flexibility for irregular subgrades.
  • Cost savings of 20–40% compared to 1.0 mm or thicker options.
  • Excellent weldability with hot wedge methods.
  • Suitable for covered or semi-exposed use with geotextile protection.
