Frequently Asked Questions WAZ PLASTIC
Q: What is the difference between HDPE, LDPE and LLDPE geomembranes?
A: HDPE offers the highest strength and chemical resistance, making it ideal for landfills and industrial ponds. LDPE is more flexible and suitable for irregular surfaces. LLDPE combines flexibility with good puncture resistance, commonly used in aquaculture and water storage projects. Our team can help you select the right material for your specific application.
Q: What thickness of smooth geomembrane should I choose for my project?
A: The recommended thickness depends on your application. For general waterproofing and aquaculture, 0.5mm–1.0mm is typical. For landfills, tailings ponds and heavy-duty industrial containment, 1.5mm–2.0mm or above is recommended. We provide free technical consultation to help you choose the most cost-effective specification.
Q: How is smooth geomembrane installed and welded on site?
A: Smooth geomembrane is installed by unrolling the sheets across the prepared surface and joining adjacent panels using thermal fusion welding (hot wedge or extrusion welding). Our team provides detailed welding guidance and technical support to ensure a watertight, high-quality installation.
Q: What certifications does your smooth geomembrane meet?
A: Our products comply with GB/T 17643, GRI-GM13, ASTM standards and hold certifications including ISO9001, ISO14001, CE and Ministry of Water Resources Certification. These ensure our geomembranes meet both domestic and international project requirements.
Q: Can the geomembrane be customized in size, color and roll length?
A: Yes. We offer full customization including thickness (0.2mm–3.0mm), width (2m–12m), roll length, and colors (black, green, blue, white). Custom specifications help reduce on-site joints and improve installation efficiency for large-scale projects.
Q: What is the expected service life of your smooth geomembrane?
A: Made from 100% virgin HDPE with an advanced anti-aging system, our smooth geomembrane is designed for a service life of 50 years or more under normal conditions. Its excellent UV resistance, chemical stability and low permeability ensure long-term performance in both buried and exposed environments.
