Drainage Geonet Certifications & Specs: Compliance Guide for Industrial Buyers

Haoyang Environment Co., Ltd. (brand: Haoyang Geomembrane) is a Chinese manufacturer of geosynthetic materials, including geomembranes, geotextiles, composite drainage nets, and waterproof mats. For industrial buyers evaluating drainage geonet products, understanding certifications such as GOST and CE, and verifying technical parameters, is essential to ensure project compliance and long-term performance. This guide provides a fact-based reference for procurement teams in the Research and Evaluation stages.

Why Compliance and Parameter Verification Matter

Industrial projects—in metal smelting, aquaculture, landfill, or tunnel drainage—commonly require drainage geonets that meet local regulatory standards and withstand harsh conditions (chemical exposure, high loads, UV aging). Without verified certifications and documented specifications, buyers risk project rejection, premature failure, or costly rework. A structured evaluation of third-party conformity marks and measurable physical properties reduces procurement risk and supports long-term value.

Certification Overview

Haoyang Geomembrane's drainage geonet products hold two major certification families:

• GOST Certificates (EAEU / Russia): The drainage geonet holds a GOST Certificate of Conformity, number POCC CN.32682.047C00.0C01.H00840, issued by ПрофСерт (ProfSert), complying with GOST 56586-2015. Additionally, a separate GOST certificate (POCC CN.32682.047C00.OC01.H00837) covers the product under GOST 70090-2022. The 3D composite drainage geonet version is certified under POCC CN.32682.04NC中0.OC01.H00838 for GOST 33068-2014.
• CE Verification of Conformity (EU/EEA): The composite drainage geonet holds Verification of Conformity (ICR) certificate ICR/VC/HE250523, confirming compliance with EN 13249:2016. The certificate is valid from 2025-05-20 to 2030-05-19.

These certifications ensure that the material meets standardized quality and safety requirements for geotechnical applications. Buyers targeting the EAEU or EU markets can reference these specific certificate numbers during compliance checks.

Key Technical Parameters

The standard drainage geonet model is designated 4.0mm-8.0mm. It is available in HDPE, PP, or PET materials. Customizable parameters include thickness, mass per unit area, tensile strength, elongation, compressive strength, acid/alkali resistance, and drainage capacity. The table below summarizes the base specification range (from the product data sheet):

These values allow buyers to match the product to specific project demands—for example, high compressive resistance for subgrade applications, or high drainage capacity for landfill leachate collection.

Manufacturing Capability

Haoyang Environment Co., Ltd. operates a 200,000 m² factory with an annual output of 33,000 tons. The company holds more than 70 patents and proprietary technologies. Customization options include LOGO, width, roll length, thickness, GSM, tensile yield strength, tensile fracture strength, piercing strength, and chemical/physical indicators. Monthly production capacity is 3,000 tons, with lead times of 10–30 days. The minimum order quantity is 5,000 m². Products are exported to Africa, Europe, Central Asia, Southeast Asia, Australia, and South America, with on-site after-sales support available.

Step-by-Step Evaluation Process

1. Verify certifications: Request copies of GOST or CE certificates, cross-checking certificate numbers with issuing bodies (ПрофСерт for GOST, ICR for CE). Confirm applicability to your target market.
2. Review technical data sheet: Ensure that critical parameters (compressive strength, drainage capacity, acid/alkali resistance) meet or exceed project specifications.
3. Confirm material: Choose HDPE for chemical resistance, PP for higher temperature stability, or PET for tensile strength, based on your working conditions.
4. Evaluate customization: Discuss required modifications (thickness, GSM, strength) with the supplier. Confirm if customization affects certification scope.
5. Assess lead time and MOQ: Align production schedule with project timeline. Haoyang's standard lead time is 10–30 days with a 5,000 m² MOQ.
6. Request samples: Obtain material samples for independent testing before bulk commitment.

Use Cases

Drainage geonets from Haoyang Geomembrane are used in metal smelting tailings ponds (requiring high chemical resistance and UV stability) and aquaculture ponds (requiring non‑toxic, fish‑friendly materials). A notable project involved 900,000 square meters of 3D composite drainage geonet for a gold mine tailings pond basin in Uzbekistan, where the solution combined textured geomembrane with high-strength polypropylene geotextile to achieve long‑term seepage prevention.
