As a Product Manager at Shanghai Lejing Building Materials Co., Ltd., I understand that civil engineering and environmental projects demand zero failure margins. You are not just buying a liner; you are investing in contamination control, water conservation, and structural integrity. Our HDPE geomembrane is a testament to industrial-grade engineering. Manufactured from virgin polyethylene resins, this HDPE geomembrane delivers exceptional chemical resistance, tensile strength, and long-term durability. Whether you are building a hazardous waste landfill or a potable water reservoir, our HDPE geomembrane provides the critical hydraulic barrier your project requires. With over a decade of manufacturing experience, LeJing ensures that every roll of our HDPE geomembrane meets rigorous global standards for waterproofing, anti-UV protection, and environmental safety.

Our HDPE geomembrane is formulated to withstand aggressive chemicals, including acids, alkalis, and hydrocarbons. This anti-corrosion feature makes it the preferred choice for lining chemical plants, mining leach pads, and sewage treatment plants. Unlike traditional concrete or clay liners, our HDPE geomembrane will not crack or degrade when exposed to harsh industrial effluents.
Exposed to direct sunlight? No problem. Our HDPE geomembrane contains 2-3% finely dispersed carbon black, providing outstanding anti-UV stabilization. This durable composition prevents cracking and embrittlement, ensuring a service life of over 50 years in most containment applications. Even after years of outdoor exposure, your HDPE geomembrane will maintain its mechanical properties and impermeability.
Smooth HDPE Geomembrane: Ideal for sub-grade contact and lining base layers, offering low friction for easy installation over surfaces.
Textured HDPE Geomembrane: Single or double textured surfaces increase friction angles by 20-30 degrees, allowing steeper slope installations without sliding—critical for landfill caps and steep reservoir banks. This textured HDPE geomembrane eliminates the need for additional soil cover on slopes.
As an eco-friendly solution, our HDPE geomembrane is inert and safe for potable water applications. It contains no plasticizers or heavy metals that could leach into soil or water. Its impermeability (permeability coefficient <10⁻¹² cm/s) creates a total waterproof barrier, preventing leachate from contaminating groundwater. For environmentally sensitive projects, this HDPE geomembrane is the responsible choice.
We don't just sell rolls; we deliver solutions. Every purchase includes free online technical support, graphic design, 3D model design, and total solution for projects. Our 24-hour online after-sale service ensures you have spare parts and installation guidance whenever you need it. From initial site assessment to final installation inspection, our team helps you succeed with your HDPE geomembrane project.
Project Background: A 50,000m² municipal solid waste landfill in northern Vietnam faced serious groundwater contamination risks. The original clay liner system was failing, and local environmental authorities demanded an immediate upgrade. The landfill's steep side slopes (ratio 1:1.5) made it impossible to use traditional smooth liners due to sliding concerns.
Solution Provided: Shanghai Lejing supplied 35,000m² of 1.5mm thick double-textured HDPE geomembrane. Our technical team provided free online installation guidance and 3D model design to optimize panel layout and reduce field seaming. The double-textured HDPE geomembrane was selected specifically for its high friction angle, which matches or exceeds that of compacted clay.
Installation & Results: The installation was completed in 28 days by the local contractor under our remote supervision. Post-installation tests using electrical leak location methods confirmed zero defects or penetrations. After 18 months of operation, the HDPE geomembrane was inspected and found to have no swelling, cracking, or UV degradation. The client reported a 40% reduction in long-term environmental compliance costs, and the landfill received operating permits for an additional 15 years.
Customer Feedback: "The LeJing HDPE geomembrane performed exactly as specified. Their technical support made a difficult installation smooth and successful."
Project Background: An industrial sewage treatment plant in Mombasa, Kenya, needed a reliable liner for its 20,000m² treatment lagoon system. The existing concrete structure had developed severe cracks due to thermal cycling and chemical attack from high-BOD effluent (pH 3-11). Concrete repairs were proving too expensive and short-lived, lasting only 6-12 months before failing again.
Solution Provided: Shanghai Lejing recommended a 2.0mm smooth HDPE geomembrane with custom 6m width panels to minimize field seams. This thickness of HDPE geomembrane was chosen to withstand the abrasive nature of sludge and the aggressive chemical environment. We provided free online technical support for surface preparation and welding procedures.
Installation & Results: The HDPE geomembrane was installed directly over the prepared concrete surface using mechanical anchors. Total installation time was only 25 days—70% faster than repairing the concrete. After three years of continuous exposure to corrosive effluents, the HDPE geomembrane remained fully intact with no signs of swelling, cracking, or permeation. Annual maintenance costs dropped by 60% compared to the previous concrete-only configuration. The treatment plant has since ordered additional HDPE geomembrane from LeJing for its expansion phase.
Customer Feedback: "We wish we had switched to LeJing's HDPE geomembrane years ago. It solved our leakage problems permanently and saved us a fortune in maintenance."
