A: Yes, our factory is very specialized in providing OEM and ODM service according to customers' requirement (including product design, material, color, size, packing, logo etc.).
❓ Frequently Asked Questions (FAQ)
❓ Q: What is the minimum order quantity for smooth geomembrane?
A: We support flexible order quantities to accommodate projects of all sizes. Please contact our sales team with your project requirements and we will provide the most suitable solution and pricing.
❓ Q: What is the difference between HDPE, LDPE and LLDPE geomembranes?
A: HDPE offers the highest strength, chemical resistance and durability, making it ideal for landfills and heavy-duty containment. LDPE is more flexible and easier to install on irregular surfaces. LLDPE combines flexibility with good puncture resistance, suitable for complex terrain and pond linings.
❓ Q: How is the smooth geomembrane installed and welded on site?
A: Smooth geomembrane is typically installed using hot wedge or extrusion welding equipment. Our team provides professional welding guidance and technical support to ensure a secure, leak-free installation. Large-width rolls are available to minimize seam joints and reduce installation time.
❓ Q: How long is the service life of your smooth geomembrane?
A: Our smooth geomembrane is manufactured from 100% virgin HDPE with a high-quality anti-aging additive system, offering an expected service life of 30–50 years under normal installation and operating conditions, depending on the application environment.
❓ Q: Is the smooth geomembrane safe for drinking water and aquaculture applications?
A: Yes. Our geomembrane is made from non-toxic, odorless raw materials and complies with CE, ISO14001 and relevant environmental standards, making it fully safe for drinking water reservoirs, fish ponds, shrimp ponds and other aquaculture applications.
❓ Q: Can the geomembrane be customized in thickness, width and color?
A: Absolutely. We offer full customization with thickness ranging from 0.2mm to 3.0mm, width from 2m to 12m, and available colors including black, green, blue and white. Custom roll lengths and packaging can also be arranged to meet your specific project requirements.
