Geomembrane price per square meter

Geomembrane price per square meter refers to the unit-area cost of polymeric liner materials used for containment, waterproofing, and environmental protection in civil and industrial engineering. Pricing reflects material type, thickness, quality standards, manufacturing process, and project-specific technical requirements rather than simple commodity value.

Technical Parameters and Specifications

Understanding geomembrane price per square meter requires evaluating core technical parameters that directly influence cost and performance.

• Material Types: HDPE, LLDPE, PVC, EPDM

• Thickness Range: 0.5 mm – 3.0 mm

• Density (HDPE): ≥ 0.940 g/cm³

• Tensile Strength: 15–28 kN/m (depending on thickness)

• Elongation at Break: ≥ 600–700%

• Tear Resistance: ≥ 200 N

• Puncture Resistance: ≥ 400 N

• UV Resistance: Carbon black content 2.0–3.0%

• Surface Options: Smooth or textured (single/double)

• Compliance Standards: ASTM, ISO, EN, GRI

Structure and Material Composition

The internal structure of a geomembrane plays a decisive role in determining geomembrane price per square meter.

• Polymer Base Layer: Virgin or controlled-grade polyethylene or PVC resin

• Carbon Black: Enhances UV stability and weather resistance

• Antioxidant Additives: Improve long-term thermal and oxidative stability

• Optional Textured Surface: Increases interface friction for slope applications

• Homogeneous Sheet Structure: Ensures uniform mechanical performance

Manufacturing Process

1. Raw Material Qualification

Resin selection directly affects geomembrane price per square meter. Certified virgin resin and additive packages increase cost but ensure compliance and durability.

2. Compounding and Blending

Automated gravimetric dosing systems ensure precise formulation of resin, carbon black, and antioxidants.

3. Extrusion Forming

Flat-die or blown-film extrusion produces sheets with controlled thickness and width tolerances.

4. Cooling and Calibration

Calendering and controlled cooling stabilize dimensions and prevent residual stress.

5. Quality Control and Testing

Mechanical, physical, and aging tests are performed per batch, contributing to higher but reliable geomembrane price per square meter.

6. Rolling and Packaging

Sheets are rolled, labeled, and packaged to maintain traceability and prevent transport damage.

Industry Comparison

Application Scenarios

• Distributors and Wholesalers: Evaluating cost-performance balance for regional markets

• EPC Contractors: Budgeting liner systems for large-scale infrastructure

• Engineering Consultants: Specifying materials aligned with performance and lifecycle cost

• Project Owners: Managing total installed cost and long-term risk

Core Pain Points and Solutions

• Unclear pricing structure: Break down geomembrane price per square meter by thickness and standard

• Hidden quality trade-offs: Verify test reports and resin origin

• Unexpected installation costs: Align material selection with welding and handling requirements

• Short service life: Prioritize durability over lowest upfront price

Risk Warnings and Mitigation Measures

Selecting geomembranes solely based on low price per square meter can lead to premature failure, leakage, and regulatory non-compliance. Risks are mitigated through third-party testing, verified certifications, and lifecycle cost analysis rather than initial material price alone.

Procurement and Selection Guide

1. Define project function and environmental exposure

2. Specify required material type and thickness

3. Identify applicable standards and certifications

4. Request detailed quotations with test reports

5. Compare geomembrane price per square meter on equal specifications

6. Evaluate manufacturer quality management systems

7. Confirm logistics, packaging, and delivery terms

8. Plan installation method and seam testing

Engineering Case Example

A wastewater treatment project required 1.5 mm HDPE geomembrane over 32,000 m². By standardizing specifications and sourcing directly from a certified manufacturer, the project achieved a competitive geomembrane price per square meter while meeting all mechanical and durability requirements. Post-installation testing confirmed full system integrity.

Frequently Asked Questions (FAQ)

• What determines geomembrane price per square meter? Material, thickness, standards, and order volume.

• Is thicker always more expensive? Yes, material consumption increases with thickness.

• Does certification affect price? Certified products usually cost more but reduce risk.

• Are textured geomembranes more expensive? Yes, due to additional processing.

• How does order quantity influence price? Larger volumes typically reduce unit cost.

• Is installation included in price per square meter? Usually not; material and installation are separate.

• Can recycled materials reduce price? Sometimes, but often restricted in critical projects.

• What is the most cost-effective material? HDPE offers strong durability-to-cost balance.

• Does shipping affect final price? Yes, especially for international projects.

• Should lifecycle cost be considered? Always, especially for environmental containment.
