❓ Frequently Asked Questions WAZ PLASTIC
What is a smooth geomembrane and what materials is it made from?
A smooth geomembrane is an impermeable synthetic liner used to control fluid migration in engineering projects. It is manufactured from HDPE, LDPE, or LLDPE materials, with HDPE being the most common due to its excellent chemical resistance, high tensile strength, and long service life.
What thickness of smooth geomembrane should I choose for my project?
The appropriate thickness depends on your project requirements. For general waterproofing applications such as ponds and canals, 0.5mm–1.0mm is typically sufficient. For landfills, tailings dams, or high-pressure environments, 1.5mm–2.0mm or thicker is recommended. Our technical team can assist you in selecting the optimal thickness based on your specific engineering conditions.
How is smooth geomembrane installed and welded on site?
Smooth geomembranes are installed by unrolling the sheets across the prepared surface and joining them using thermal fusion welding (hot wedge or extrusion welding). The smooth surface allows for efficient and fast laying. We provide professional welding guidance and construction plan support to ensure proper installation and long-term performance.
Is smooth geomembrane safe for use in drinking water reservoirs and aquaculture?
Yes. Our smooth geomembranes are manufactured from 100% virgin, non-toxic, and odorless raw materials. They comply with CE, ISO9001, ISO14001, and relevant environmental standards, making them fully safe for drinking water storage, aquaculture ponds, fish and shrimp farming, and other food-contact or sensitive water applications.
What is the expected service life of your smooth geomembrane?
Our smooth geomembranes are formulated with a high-quality anti-aging system using 100% new HDPE particles. Under normal installation and operating conditions, the expected service life is 30–50 years. The material remains stable across a wide temperature range of -60℃ to 60℃, ensuring reliable long-term performance even in extreme climates.
Can you provide custom sizes, colors, and packaging for bulk orders?
Absolutely. We offer full OEM and ODM services. Thickness can be customized from 0.2mm to 3.0mm, width from 2m to 12m, and available colors include black, green, blue, and white. Roll lengths and packaging can also be tailored to your project requirements. Please contact us with your specifications for a detailed quotation.
