There is no fixed price for geomembranes; the cost depends primarily on thickness and quality standards. Prices for standard specifications range from approximately 1 to 20 yuan per square meter; thinner versions used for fish ponds are cheaper, while thicker versions used in engineering projects are significantly more expensive.
**Approximate prices by thickness**
* **Around 0.3 mm:** Enterprise-standard products cost about 1.6–3 yuan/m²; National-standard products made from virgin resin cost 2.5–5 yuan/m². Suitable for shallow lotus ponds or seedling nurseries.
* **Around 0.5 mm:** Enterprise-standard products cost about 3–5 yuan/m²; National-standard products made from virgin resin cost 4–7.5 yuan/m². This specification is commonly used for standard aquaculture ponds.
* **1.0 mm and above:** Enterprise-standard products cost about 5–9 yuan/m²; National-standard products made from virgin resin cost 9–15 yuan/m². This thickness is typically used for landfills or wastewater treatment ponds.
**Why is there such a price difference?**
* **Material standards:** National-standard products are more expensive than enterprise-standard ones because they undergo stricter testing and offer superior aging resistance, resulting in a significantly longer service life.
* **Raw material composition:** Virgin resin is more expensive than recycled material; while recycled material is cheaper, it generally has lower tensile strength and poorer corrosion resistance.
* **Purchase quantity:** Prices are negotiable for large wholesale orders, whereas unit prices are higher for small-scale purchases; shipping costs are sometimes calculated separately.
**How to get the best deal**
* **Determine the application scenario:** For fish pond seepage control, 0.5 mm National-standard virgin resin material offers the best value; for engineering projects, it is recommended to select 1.0 mm or thicker material in accordance with design specifications.
* **Compare quotes from multiple suppliers:** Prices for the same specification can vary by several yuan between manufacturers; clarify whether the product meets National or Enterprise standards and whether it is made from virgin or recycled resin.
* **Check the actual transaction price:** Online listed prices are sometimes just 'teaser' rates to attract traffic; before placing an order, ask the manufacturer for the final delivered price, including shipping and potential waste/loss costs.
