1. What Is A HDPE Geomembrane Liner?

A High-Density Polyethylene (HDPE) geomembrane liner is a synthetic, impermeable membrane made from virgin polyethylene resin, designed to prevent fluid migration in containment systems. With a density of 0.94 g/cm³, HDPE liners offer exceptional tensile strength (27 N/mm at break, per ASTM D6693) and low permeability (≤10⁻¹³ cm/s), making them ideal for harsh environments. Available in smooth or textured finishes, these liners are thermally welded on-site to create seamless barriers, ensuring 99% containment efficiency. Geomembrane HDPE liners is made with 0.2~3mm in thickness and up to 10m in length, they are widely used in landfills, ponds, and mining operations, providing a robust solution for environmental protection and resource conservation, backed by a 50+ year lifespan when covered.

3. How Thick Is the HDPE Geomembrane Liner? mm, Mils, and Micron

HDPE geomembrane liners are available in various thicknesses to suit project requirements, typically ranging from 0.5 mm to 3.0 mm. Thickness is measured in millimeters (mm), mils (1 mil = 0.0254 mm), and microns (1 micron = 0.001 mm). Common thicknesses include:

5 mm (20 mils, 500 microns): Used for low-stress applications like aquaculture ponds.
0 mm (40 mils, 1000 microns): Balances strength and cost for water storage and agricultural ponds.
5 mm (60 mils, 1500 microns): Standard for landfills and wastewater lagoons.
0 mm (80 mils, 2000 microns): Preferred for mining and hazardous waste containment.
0 mm (120 mils, 3000 microns): Used in high-stress environments like heap leach pads.

Thicker liners (e.g., 80+ mils) offer 30% greater puncture resistance (356 N, ASTM D4833) and 50% longer service life, per GRI GM13 standards. Selection depends on subgrade conditions, hydrostatic pressure, and regulatory requirements.

4. Key Features of HDPE Geomembrane Liner?

4.1 Exceptional Waterproofing

HDPE geomembrane liners are 100% waterproof, providing reliable protection against liquid seepage. This feature is crucial for applications such as aquaculture ponds, landfills, and wastewater treatment facilities.

4.2 High Tensile Strength

These liners exhibit high tensile strength, with a break strength of up to 28 MPa and an elongation at break of 700%. This makes them highly resistant to tearing and puncturing, ensuring long-term stability and durability.

4.3 Excellent Chemical Stability

HDPE geomembrane liners are resistant to a wide range of chemicals, including acids, alkalis, and salts. They can withstand corrosion from over 80 strong chemical media, making them suitable for use in harsh environments such as mining and chemical reaction tanks.

4.4 UV Resistance

Thanks to the addition of carbon black, HDPE geomembrane liners possess good UV resistance. This prevents degradation when exposed to sunlight, extending the lifespan of the liner.

4.5 Temperature Resistance

These liners can withstand extreme temperatures, making them suitable for use in various climatic conditions.

4.6 Environmental Friendliness

The materials used in HDPE geomembrane liners are non-toxic and environmentally friendly. They do not produce harmful substances during use, making them ideal for applications in aquaculture and drinking water ponds.

6. What Is the Difference Between HDPE Liner and PVC Liner?

HDPE and PVC geomembrane liners serve similar containment purposes but differ significantly in composition, performance, and application:

6.1 Material Composition

HDPE: Made from high-density polyethylene (96-97% resin, 2-3% carbon black), offering high density (0.94 g/cm³) and rigidity.
PVC: Composed of polyvinyl chloride with plasticizers, providing flexibility but lower density (1.2-1.4 g/cm³).

6.2 Thickness and Strength

HDPE: Typically 0.5-3.0 mm (20-120 mils); requires 60 mils for EPA compliance due to welding needs. Offers 30% higher puncture resistance (356 N vs. 267 N).
PVC: Ranges from 0.5-1.5 mm (20-60 mils); 30 mils meets EPA standards due to superior weldability. More flexible, with 50% greater elongation before failure.

6.3 Chemical Resistance

HDPE: Superior resistance to hydrocarbons and solvents, ideal for mining and oil containment.
PVC: Better suited for municipal solid waste (MSW) landfills with neutral pH leachates; less resistant to hydrocarbons.

6.4 UV and Temperature Performance

HDPE: Excellent UV resistance (20+ years exposed) and performs well in -20°C to 60°C.
PVC: Requires soil cover to prevent UV degradation; loses flexibility below 0°C.

6.5 Installation

HDPE: Requires field welding, increasing costs by 10-15%; less conformable to subgrades.
PVC: Flexible, allowing 20% fewer field seams; supports factory seaming and adhesive bonding.

6.6 Cost

HDPE: $0.5-$2 per m², cost-effective for large projects.
PVC: $0.8-$2.5 per m², often pricier due to plasticizer costs.

Recommendation: Choose HDPE for chemical-intensive, exposed, or large-scale projects; opt for PVC for flexible, smaller-scale applications like MSW landfills.

7. What Is HDPE Geomembrane Liner Used For?

HDPE geomembrane liners are versatile, serving critical roles across industries:

Landfills: Serving as base liners and caps to prevent leachate migration and gas emissions.
