What Is The Difference Between PVC And HDPE Geomembrane?

PVC geo membrane is a geomembrane made from polyvinyl chloride raw materials. It is a new type of anti-seepage material. HDPE geomembrane(HDPE Impermeable Membrane) is made from high-density polyethylene (HDPE) and is produced through a three-layer co-extrusion blow molding technology. No plasticizers are added, and its chemical stability is more pure. It is a flexible waterproof material with a very high seepage resistance coefficient. Apart from the differences in raw materials, there are also certain variations in their performance parameters (such as waterproofing performance, tensile strength, weather resistance, chemical corrosion resistance, and puncture resistance). Therefore, their application scenarios are also different:

PVC geotextile membrane:

Suitable for scenarios with high requirements for flexibility and low environmental temperatures, such as:

Subterranean garages for waterproofing, rooftop greening, artificial landscape lakes

Small channels, lotus ponds, fish ponds

Note: Avoid prolonged exposure to strong sunlight or contact with strong solvents

HDPE Geomembrane:

Suitable for large-scale projects with high requirements for impermeability and durability, such as:

Landfill sites, sewage treatment plants, hazardous waste landfill sites; large reservoirs, dams, channel seepage prevention, tailings ponds;

Chemical tanks, foundation of oil tanks, waste residue sites;

Advantages: Can last for over 30 years in outdoor exposed environments, with low maintenance costs.
