Custom Pond Liner Thickness 0.5mm 0.75mm PVC Geomembrane
Manufacturing Process
Raw Material Blending: PVC resin, plasticizers, and additives are precisely dosed in high-shear mixers.
Extrusion Calendering: Twin-screw extruders melt the blend and form a stable sheet.
Thickness Calibration: Automated rollers ensure uniform 0.5mm or 0.75mm thickness.
Cooling & Surface Treatment: Smooth or textured finish depending on project requirements.
Online Quality Inspection: Pin-hole detection, tensile testing, and thickness scanning.
Roll Winding & Packaging: Controlled tension winding to avoid internal stress deformation.

Applications
Distributors: Large-scale pond liner inventory for landscaping and aquaculture supply.

Engineering Firms: Project design for urban water features and lined reservoirs.
Aquaculture Farms: Shrimp ponds, fish tanks, reservoir lining.
Wastewater Projects: Secondary containment basins.
Core Pain Points & Solutions
Uneven Thickness in Low-Grade Liners → Automated calender control ensures uniform 0.5mm/0.75mm thickness.
Poor Seaming Strength → PVC supports hot-air/solvent welding with high seam peel resistance.
UV Degradation → Formulation with TiO₂ and stabilizers improves service life in outdoor ponds.
Installation Difficulties → High flexibility allows easy cold-weather installation and tight corner fitting.
Risk Warnings & Mitigation
Do not install at temperatures below -5°C without preheating to avoid micro-cracking.
Avoid sharp aggregates; apply 150–300 g/m² geotextile cushioning layer.
Confirm solvent compatibility during seaming to prevent joint softening.
Prevent liner stretching over 3% during installation to avoid long-term deformation.
Procurement & Selection Guide
Confirm targeted pond function (aquaculture, decorative, industrial containment).
Select appropriate thickness (0.5mm for light-duty, 0.75mm for medium-duty).
Verify mechanical parameters (tensile, puncture, elongation).
Check production certificates (CE, ISO 9001, material traceability).
Request roll width/length customization based on installation layout.
Assess welding method compatibility (hot air / solvent / extrusion).
Evaluate supplier QC reports for each batch.
Confirm logistics and packaging suitability for overseas transport.
Engineering Case Study
An EPC contractor executed a 5,000 m² aquaculture pond requiring flexible lining in a temperate climate. Custom Pond Liner Thickness 0.5mm 0.75mm PVC Geomembrane was supplied in 6 m wide rolls to minimize seams. Hot-air welding achieved seam strength of 90% of parent material. A 200 g/m² geotextile provided underlay protection. Installation was completed in 3 days with zero leakage detected during the 72-hour water retention test.
