GEOLINE HD500 is a high-performance 0.5 mm (500 micron) HDPE geomembrane liner designed for waterproofing and containment applications where durability, flexibility, and long-term performance are critical. Manufactured using premium-grade high-density polyethylene, this liner delivers exceptional resistance to chemicals, UV exposure, puncture, and environmental stress cracking.

Engineered for African conditions, GEOLINE HD500 provides a cost-effective yet professional-grade lining solution for:

• Farm dams & irrigation reservoirs

• Fish ponds & aquaculture systems

• Water storage tanks

• Canals & irrigation channels

• Wastewater ponds

• Agricultural containment pits

• Landscaping water features

• Mining and industrial containment

• Temporary water storage projects

Why GEOLINE HD500 Dominates Standard Plastic Liners

Unlike ordinary plastic sheeting or low-density films, GEOLINE HD500 is a true geomembrane liner designed according to geosynthetic engineering principles. This means:

✔ Higher tensile strength
✔ Superior UV stability
✔ Greater puncture resistance
✔ Longer design life
✔ Professional installation compatibility
✔ Weldable seams for large projects

This makes it the preferred choice for engineers, contractors, farmers, and developers across South Africa, SADC, and wider Africa.

Key Specifications

• Material: High-Density Polyethylene (HDPE)

• Thickness: 0.5 mm / 500 micron

• Roll Size: 5.8 m × 100 m

• Coverage: 580 m² per roll

• Colour: Black (UV stabilised)

• Chemical Resistance: Excellent

• Weldability: Hot wedge / extrusion welding compatible

• Design Life: Long-term outdoor durability

Advantages for African Projects

GEOLINE HD500 is specifically selected to perform under African climate extremes, including:

• High UV exposure

• Temperature fluctuations

• Dry-wet soil cycles

• Remote installations

• Heavy equipment traffic nearby

Its wide-width roll format reduces seams, saving both installation time and welding costs - a critical advantage for large agricultural or civil projects.

The post GSE HDPE Smooth Geoliner (1.50mm thick - 7m x 150m Roll) appeared first on Geosynthetics South Africa.

This smooth high-density polyethylene geomembrane is supplied for welded lining installations in engineered containment systems. Product thickness, chemical compatibility, protection layers, terminations and installation details must suit the stored liquid, subgrade, operating conditions and approved design.

Current supplied roll format

Allow for seam overlaps, anchor trenches, terminations and cutting waste when estimating the order quantity. The nominal roll area is not the net installed coverage.

Specification and technical documentation

Use the current technical data and conformity documents for the exact supplied grade. Check the required tensile, puncture, tear, stress-crack resistance and durability properties against the project specification. Suitability for a particular mining, waste, reservoir or pond application requires design approval; the application name alone does not establish that 1.00 mm is the correct thickness.

The linked manufacturer technical data sheet remains the reference for material properties. Its stated roll format may differ from the current supplied 7 m × 220 m format confirmed for this catalogue item.

Supply, delivery and installation

Geosynthetics South Africa coordinates product supply, delivery and specialist installation across South Africa and Southern Africa, supported by our parent, Geosynthetics Africa, and group companies for wider African projects. Installation and QA/QC requirements are defined for the agreed scope.
