Our quality control system covers every major stage from raw material entry inspection to in-line monitoring and final laboratory sampling inspection, helping ensure stable physical performance and full-batch consistency.
We exclusively utilize 100% virgin HDPE resin sourced from globally Tier-1 manufacturers such as Sabic, Chevron Phillips, or Borealis. Every batch is strictly accompanied by the original Certificate of Analysis (COA) to ensure 100% material traceability and to guarantee zero use of recycled content.
Prior to production, all raw materials undergo a secondary verification process. Our Quality Assurance (QA) team audits the documentation accuracy and performs sampling tests for Melt Flow Rate (MFR) and Density to ensure the feedstock aligns perfectly with our internal high-performance specifications.
Our production lines are integrated with advanced automatic ultrasonic thickness-monitoring systems. This real-time, closed-loop control system ensures that thickness deviation across the entire roll is maintained within a strict ±3%, far exceeding the standard industry requirements for structural uniformity.
Upon completion, each roll is subjected to a rigorous inspection. We maintain a full production pedigree for every batch to ensure strict compliance, recording:
Before shipment, samples from every batch are tested in our state-of-the-art laboratory to ensure full compliance with GRI-GM13 and ASTM International standards, specifically:
We utilize a multi-layer protection system designed to withstand the rigors of international sea freight and site-side storage, ensuring material integrity from factory to installation.
Rolls are wound on high-density, 10mm+ wall-thickness reinforced cores to prevent structural collapse during high-stacking in containers.
Each roll is encased in dual-layer UV-stabilized PE wrapping and an outer tear-resistant woven jacket to eliminate dust contamination and mechanical abrasion.
Every roll features a weatherproof thermal-printed label detailing Thickness (to ±0.01mm precision), Width, Length, Batch ID, and a Raw Material MTR (Material Test Report) reference.
For overseas buyers, we provide a comprehensive Container Loading Report, including structural integrity checks of the container, digital photos of the loading process, and verified seal numbers to mitigate transit risk.
Our facility operates under a policy of "Verification over Promise." We facilitate independent testing to ensure all shipments meet or exceed GRI-GM13 (for HDPE) or GRI-GM17 (for LLDPE) international standards.
We support on-site sampling and security sealing by globally recognized agencies, including SGS, Intertek (ITS), BTTG, and TRI Environmental.
Our lab is GAI-LAP accredited, ensuring that our internal testing for Tensile Strength, Puncture Resistance, and OIT (Oxidative Induction Time) aligns perfectly with third-party results.
We welcome third-party technical audits to verify our ISO 9001:2015 Quality Management Systems and raw material silos.
We exclusively utilize 100% Virgin HDPE Resin sourced from Tier-1 global producers (e.g., Chevron Phillips, Borealis, or Sabic) to ensure long-term molecular stability.

Follow the recommended site preparation, overlap control, welding method, and inspection process to achieve stable installation quality and reliable seam performance.
Make sure the subgrade is level and well compacted, with no sharp stones, debris, or other materials that may damage the membrane during installation.
The compaction degree should reach at least 90% to provide a stable and uniform base for membrane laying.
Recommended Compaction: ≥ 90%
The overlap width between adjacent membrane sheets must be accurately controlled to ensure proper welding quality and seam integrity.
The recommended overlap width is between 100 mm and 150 mm, depending on site conditions and installation requirements.
Recommended Overlap Width: 100 mm – 150 mm
Dual-track hot wedge welding is recommended for the main seams, while extrusion welding is suitable for irregular details, corners, and special-shaped areas.
Dual-track welding allows pressure testing of the air channel, helping verify seam continuity and minimize leakage risk.
Main Seams: Dual-Track Hot Wedge Welding
On-site inspection can be carried out using an air pressure test or vacuum box test to check seam tightness and welding consistency.
For air pressure testing, maintain the test pressure at 0.25 MPa and confirm that no pressure drop occurs within 5 minutes.
Air Pressure Test: 0.25 MPa / 5 Minutes / No Pressure Loss
Built for Sea Freight, Cost Control, and Project-Based Supply
We focus on the four details buyers care about most: shipping protection, container efficiency, warranty coverage, and customization flexibility. Each point is prepared to reduce transport risk, lower freight cost, and improve installation efficiency on site.
Each roll is packaged with round cable ties and a sturdy paper or plastic core to improve stability during storage, loading, and long-haul sea transport.
Roll length can be calculated according to container size, including 20GP and 40HQ, so container space is used more efficiently.
A quality warranty agreement of 10 to 20 years can be provided depending on the application environment. Service life can exceed 50 years when buried.
Custom roll width and roll length are available for project-based supply. Width can reach up to 8 meters, which helps improve laying efficiency.
Below are some of the most common questions buyers ask about our geomembrane and geotextile products, including MOQ, lead time, UV resistance, test reports, customization, and quotation requirements.
We usually support trial orders starting from 1–3 tons for regular specifications. For export shipments, we generally recommend at least 1 × 20GP container, as container loading usually offers a more competitive cost per square meter. For customized thickness, width, or roll length, the MOQ may be higher depending on production scheduling and order arrangement.
For standard products, production is usually arranged within 7–15 days after specifications are confirmed and the deposit is received. For customized orders, mixed-container loading, or peak-season production, the lead time is typically 15–25 days. We confirm the delivery schedule before mass production so buyers can plan installation and project timing more efficiently.
We mainly supply HDPE geomembrane, LLDPE geomembrane, textured geomembrane, and PET continuous filament non-woven geotextile. These materials are widely used in mining, landfill, aquaculture, hydraulic engineering, civil engineering, and environmental protection projects.
We supply geomembrane specifications suitable for a wide range of project requirements. For many engineering applications, the commonly requested thickness range is 0.75 mm to 3.0 mm. We also support customized roll width and roll length to help reduce seam quantity and improve installation efficiency on site.
We control UV performance through raw material selection, additive formulation, and batch-based quality control. Raw materials are checked carefully before production, and finished products are tested in our laboratory before shipment. For geotextile products, we also pay close attention to UV durability and flow performance to ensure they are suitable for outdoor engineering applications.
Yes. We provide Technical Data Sheets (TDS) and can also support product test data for project evaluation. Depending on the order and specification, the documents may include thickness, tensile properties, puncture-related indicators, and other key technical values required for approval and procurement review.
We control quality through four main stages: raw material inspection, production monitoring, finished product laboratory testing, and shipment release checking. Shipment is not arranged until the finished goods pass internal inspection. We also keep retained samples for each production batch to support traceability and after-sales service.
Yes. We keep retained samples of finished products as part of our quality control system. This helps us verify batch consistency, review technical questions, and support customers more efficiently if quality confirmation is needed after delivery.
Yes. We support customization in specifications, dimensions, and technical indicators. We can adjust thickness, width, roll length, surface type, and packing marks according to project requirements. For large projects, we recommend confirming the specification sheet before production to reduce procurement risk and avoid repeated revisions.
Yes. We do not only quote material prices; we also help customers evaluate installation efficiency, seam reduction, loading optimization, and overall project cost per square meter. In many cases, better roll sizing and container planning can reduce both freight cost and on-site labor time.
Our products are suitable for six major application areas: mining, hydraulic engineering, aquaculture, landfill, civil engineering, and environmental protection. Based on project conditions, we can recommend suitable materials for containment, separation, filtration, protection, or reinforcement applications.
To prepare an accurate quotation, we usually need six key details: product type, thickness or weight, roll size, order quantity, destination port, and application. If you can also provide drawings, technical standards, or tender requirements, we can often reduce 1–3 rounds of repeated communication and provide a more accurate quotation faster.
