HDPE & LLDPE Geomembrane Liner

Geomembrane Liner – HDPE & LLDPE for Water and Environmental Containment

Global Geomembrane Liner Case Study Collection

GeoSynSource supplies HDPE and LLDPE geomembrane liners for ponds, reservoirs, landfills, mining, wastewater and other containment applications.

Our current HDPE geomembrane range includes smooth and textured surfaces, with technical data covering 0.75–3.0 mm smooth geomembrane and 1.0–2.5 mm textured geomembrane.

Available roll widths can range from approximately 2 to 12 meters, depending on material, thickness and project requirements.

Geomembrane selection should consider more than thickness alone. The application, surface type, subgrade condition, puncture risk, slope, chemical environment and installation requirements can all influence the final product choice.

Which Geomembrane Fits Your Project?

The best place to start is the project application and site conditions, rather than choosing a geomembrane only by thickness or price.

Project	Commonly Considered Option	Key Selection Factors
Pond / Aquaculture	Smooth HDPE or LLDPE	Subgrade, puncture risk, depth, exposure and protection
Reservoir	Smooth HDPE	Project area, slope, seam layout, exposure and subgrade
Landfill	Smooth or textured HDPE	Interface conditions, chemical environment and liner-system design
Mining / Heap Leach	HDPE geomembrane	Chemical environment, puncture risk, slopes and QA/QC
Wastewater	Project-compatible geomembrane	Chemical compatibility, seams, subgrade and exposure
Sloped Containment	Textured HDPE may be considered	Interface friction, slope geometry and system stability

These are general selection considerations rather than project design specifications.

Final material, thickness and surface requirements should follow the actual site conditions, project specification and engineering requirements.

HDPE and LLDPE Geomembrane Options

HDPE Geomembrane

HDPE geomembrane is widely used as a low-permeability lining material in environmental and water-containment systems.

Typical applications include:

Landfills
Mining heap leach pads
Reservoirs
Farm ponds
Aquaculture ponds
Wastewater lagoons
Canals
Industrial containment
Environmental protection systems

HDPE geomembrane is available in both smooth and textured surfaces.

LLDPE Geomembrane

LLDPE geomembrane is available as an alternative liner option for projects with different material and installation requirements.

The appropriate material should be selected according to the project specification, site conditions and overall containment system.

For a more detailed material comparison, refer to our HDPE vs LLDPE Geomembrane Guide.

Smooth vs Textured Geomembrane

The geomembrane surface affects how the liner interacts with adjacent soil, geotextile or drainage materials.

Factor	Smooth Geomembrane	Textured Geomembrane
Surface	Smooth	Roughened / textured
Current Thickness Range	0.75–3.0 mm	1.0–2.5 mm
Asperity	—	0.25 mm in current TDS
Typical Use	General containment applications	Applications where interface friction is an important consideration
Common Projects	Ponds, reservoirs, lagoons and flatter containment areas	Landfill slopes and other sloped liner systems
Main Selection Factors	Thickness, seams, subgrade, puncture and exposure	Slope geometry, interface conditions and system stability

A textured geomembrane is not automatically better than a smooth geomembrane.

Smooth material is commonly used in general containment applications. Textured material may be considered where increased interface interaction is important, particularly on slopes.

Available Geomembrane Thickness

Current smooth HDPE geomembrane technical data covers:

0.75 mm · 1.0 mm · 1.5 mm · 2.0 mm · 3.0 mm

Current textured HDPE geomembrane technical data covers:

1.0 mm · 1.5 mm · 2.0 mm · 2.5 mm

The required geomembrane thickness depends on several project factors, including:

Application
Subgrade condition
Puncture risk
Contained liquid or waste
Slope geometry
Exposure conditions
Protective layers
Installation method
Project specification

A thicker geomembrane generally provides higher values for several mechanical properties under comparable test conditions, but thickness alone does not determine liner-system performance.

Poor subgrade preparation, sharp stones or poor seam quality can still affect containment performance even when a relatively thick liner is used.

Key Properties to Check When Comparing Geomembrane

Technical data is useful for product comparison, but no single value should be used alone to determine project suitability.

Tensile Properties

Tensile data describes material behavior under the stated test conditions.

These values are useful for comparing products tested on a consistent basis, but they do not replace project-specific liner-system evaluation.

Puncture and Tear Resistance

Puncture and tear resistance are particularly important where the geomembrane may be exposed to:

Irregular subgrade
Coarse soil
Stones
Aggregate
Construction handling
Localized mechanical damage

Where puncture risk is significant, subgrade preparation and protective geotextile may also need to be considered.

Carbon Black

The current HDPE geomembrane technical data specifies:

2.0–3.0% carbon black content.

OIT

OIT is one of the technical indicators reported in the current geomembrane TDS.

It should be considered together with material formulation, aging data, temperature and actual exposure conditions rather than being treated as a direct prediction of field service life.

Geomembrane Applications

Pond and Aquaculture Lining

HDPE and LLDPE geomembrane liners can be used for:

Farm ponds
Fish ponds
Aquaculture ponds
Irrigation ponds
Water storage ponds

Selection should consider subgrade preparation, puncture risk, water depth, exposure and protection requirements.

Reservoir and Water Containment

HDPE geomembrane is commonly considered for:

Irrigation reservoirs
Agricultural water storage
Artificial lakes
Canals
Water-conservation projects
Water-treatment reservoirs

Large projects should consider subgrade preparation, panel layout, slopes, seam arrangement, anchorage and protection requirements.

Landfill Containment

Geomembrane can form the low-permeability barrier within an engineered landfill liner or cover system.

Depending on the project design, the complete system may also include:

Compacted clay
Geosynthetic clay liner
Protective geotextile
Drainage geocomposite
Leachate collection layers

Geomembrane should therefore be evaluated as part of the complete containment system, rather than as a standalone solution.

Mining and Heap Leach Applications

Geomembranes are used in applications such as:

Heap leach pads
Process ponds
Solution ponds
Tailings-related containment
Mining water containment

Important factors include chemical exposure, puncture risk, slopes, liner protection and installation QA/QC.

Wastewater and Environmental Containment

Geomembrane liners can also be used for:

Wastewater lagoons
Sewage ponds
Industrial wastewater
Retention ponds
Waste containment
Environmental-protection projects

For project-specific chemical environments, material compatibility should be evaluated before final selection.

Installation Factors That Affect Performance

Geomembrane performance depends on both the material and the installed liner system.

Important installation factors include:

Proper subgrade preparation
Appropriate panel placement
Controlled seam welding
Puncture protection where required
Anchorage where required by design
Installation QA/QC for critical projects

Sharp stones, poor subgrade preparation or poor seam quality can affect containment performance even when the geomembrane meets its specified material properties.

Does a Geomembrane Need Geotextile Protection?

Geomembrane provides the primary low-permeability containment barrier, while geotextile may be used for protection, separation, filtration or drainage.

Where stones, irregular soil or adjacent materials create puncture risk, a suitable protective geotextile may be included according to the liner-system design.
