    Q & A WAZ PLASTIC

    Q Are you a manufacturer or trading company?
    A We are a professional manufacturer and exporter with ISO9001 & SGS Certificates, who is specialized in plastic products for more than 20 years.
    Q Can you do OEM and ODM?
    A Yes, our factory is very specialized in providing OEM and ODM service according to customers' requirements (including product design, material, color, size, packing, logo etc.).

    Frequently Asked Questions WAZ PLASTIC

    Q What is the difference between HDPE, LDPE and LLDPE geomembranes?
    A HDPE offers the highest strength, chemical resistance and UV stability, making it ideal for landfills and industrial containment. LDPE is more flexible and easier to install on irregular surfaces. LLDPE combines flexibility with good tensile strength, suitable for applications requiring more elongation, such as pond liners and canal lining.
    Q What thickness of smooth geomembrane should I choose for my project?
    A The appropriate thickness depends on the application. For general pond lining and agriculture, 0.5mm–1.0mm is commonly used. For landfills, hazardous waste containment and heavy-duty industrial applications, 1.5mm–2.0mm or thicker is recommended. Our technical team can advise the best specification based on your project requirements.
    Q How is the smooth geomembrane installed and welded on site?
    A Smooth geomembranes are typically installed by unrolling panels across the prepared surface and joining them using hot wedge welding or extrusion welding methods. The smooth surface allows panels to lay flat quickly, reducing installation time. We provide professional welding guidance and construction support to ensure proper seam integrity.
    Q What quality certifications does your smooth geomembrane comply with?
    A Our smooth geomembranes comply with GB/T 17643, GRI-GM13, and ASTM standards. We hold certifications including ISO9001, ISO14001, Ministry of Water Resources Certification, and CE certification, ensuring the products meet both domestic and international quality and environmental requirements.
    Q Can the geomembrane be used for drinking water reservoirs and aquaculture ponds?
    A Yes. Our smooth geomembranes are manufactured from 100% virgin, non-toxic and odorless raw materials, making them safe for contact with drinking water and aquaculture environments such as fish ponds, shrimp ponds and sea cucumber breeding ponds. They comply with relevant environmental and food-safety standards.
    Q What is the expected service life of the smooth geomembrane?
    A When properly installed and maintained, our HDPE smooth geomembranes have an expected service life of 30–50 years. The high-quality anti-aging system incorporated into the raw materials ensures long-term UV resistance, chemical stability and mechanical durability even under harsh outdoor conditions.
