geomembrane and geotextile supplier

A geomembrane and geotextile supplier provides engineered polymer-based barrier and filtration materials used in civil, environmental, and hydraulic engineering projects to control seepage, reinforce soil, and improve long-term structural stability.

Technical Parameters and Specifications

All parameters listed below reflect commonly accepted international engineering standards (ASTM / ISO) and are adjustable according to project requirements.

• Geomembrane Thickness: 0.5 mm – 3.0 mm

• Geomembrane Density (HDPE): ≥0.94 g/cm³

• Tensile Strength: ≥15–28 MPa (ASTM D638)

• Elongation at Break: ≥700%

• Carbon Black Content: 2.0–3.0%

• Geotextile Mass: 100–1200 g/m²

• Geotextile Tensile Strength: 8–120 kN/m

• Water Permittivity: ≥0.05 s⁻¹

Structure and Material Composition

• Geomembrane Layers

• Primary polymer resin (HDPE / LLDPE / PVC)

• Carbon black dispersion for UV resistance

• Antioxidant and thermal stabilizers

• Geotextile Structure

• Nonwoven needle-punched fibers (PP / PET)

• Continuous filament or staple fiber layout

• Thermally or mechanically bonded matrix

Manufacturing Process

1. Raw Material Inspection: Polymer resin melt index and density verification

2. Extrusion or Spinning: Flat die extrusion for geomembrane; filament spinning for geotextile

3. Calendering / Needle Punching: Thickness control and mechanical reinforcement

4. Surface Treatment: Texturing or calendared smooth finish

5. Inline Quality Control: Thickness gauge, tensile sampling, and visual inspection

6. Final Winding and Packaging: Controlled tension winding to avoid micro-cracking

Industry Comparison

Application Scenarios

• Distributors: Stock supply for regional infrastructure projects

• EPC Contractors: Landfill lining, tailings dams, canal systems

• Engineering Firms: Road subgrade stabilization and drainage layers

• Developers: Water reservoirs and industrial ponds

Core Pain Points and Solutions

• Inconsistent Quality: Resolved through batch traceability and standardized testing

• Premature Aging: Addressed with verified antioxidant packages

• Installation Failure: Mitigated by welding guidance and field support

• Supply Delays: Managed via production planning and inventory buffering

Risk Warnings and Mitigation

• Avoid non-certified materials without test reports

• Confirm chemical compatibility with site liquids

• Ensure subgrade preparation meets design tolerance

• Use qualified welding technicians on-site

Procurement and Selection Guide

1. Define project function (lining, filtration, reinforcement)

2. Confirm design standards and specifications

3. Match material type to chemical and mechanical exposure

4. Request third-party test reports

5. Evaluate production capacity and delivery schedule

6. Assess technical support and after-sales service

Engineering Case Example

In a municipal landfill project covering 120,000 m², a geomembrane and geotextile supplier delivered 2.0 mm HDPE liners combined with 800 g/m² nonwoven geotextiles. The system achieved verified leakage control below regulatory limits after 36 months of operation.
