1. What Is HDPE Geomembrane Liner?
HDPE (High-Density Polyethylene) geomembrane liners play a crucial role in various civil engineering and environmental applications. These liners are designed to provide reliable containment, barrier systems, and waterproofing solutions. Made from high-density polyethylene resin, HDPE geomembrane liners offer outstanding characteristics such as excellent chemical resistance, durability, flexibility, and impermeability.
The primary purpose of an HDPE geomembrane liner is to serve as a low-permeability synthetic membrane or barrier in conjunction with geotechnical engineering materials. It effectively controls the migration of fluids or gases within man-made projects, structures, or systems. The liner’s composition and formulation provide it with desirable properties, including high tensile strength, impact resistance, anti-penetration capabilities, and resistance to acids, alkalis, heat, weathering, and wear.
HDPE geomembrane liners find extensive applications in landfill projects, catering to waste management needs. They are suitable for waste landfills, industrial waste landfills, hazardous waste landfills, solid waste landfills, tailings landfills, waste slag landfills, tail mine seepage prevention, and other projects related to solid and hazardous waste containment.
When constructing solid waste landfills, it is essential to employ anti-seepage films with a minimum thickness of 1.5mm. Additionally, the width of the liner should exceed 6 meters to minimize the number of welded joints. Studies indicate that a significant portion of leakage in landfills occurs at these joints. To enhance performance, rough-surfaced textured HDPE geomembrane liners can be utilized on slope surfaces, increasing the friction coefficient and maximizing the available volume.
HDPE geomembrane liners are versatile materials extensively used in civil engineering and environmental applications. Their unique properties make them reliable barriers, providing containment and waterproofing solutions in various projects, particularly in landfill applications.
2. What Is The Best Thickness of HDPE Geomembrane Liner for Solid Waste Landfill?
The best thickness for an HDPE geomembrane liner in a solid waste landfill is generally 1.5mm or more. This thickness ensures effective seepage prevention and containment of the landfill. The liner acts as an anti-seepage layer, providing a barrier between the waste and the surrounding environment.
In landfill applications, thousands of tons of garbage are typically deposited, necessitating a robust liner to withstand the weight and pressure. The 1.5mm thickness or greater ensures the liner’s durability and ability to resist punctures and tears caused by sharp objects within the waste.
Additionally, it is recommended that the width of the liner be greater than 6 meters. This wider width reduces the number of welded joints required during installation. Studies have shown that approximately 70% of leakage in landfills occurs at these welded joints. By minimizing the number of joints, the risk of potential leaks and environmental contamination can be significantly reduced.
To enhance performance and stability, a rough-surfaced textured HDPE geomembrane liner can be used on slope surfaces within the landfill. This textured surface increases the friction coefficient, providing additional stability and preventing slippage of the waste material. Moreover, maximizing the available volume helps optimize the landfill’s capacity.
Using an HDPE geomembrane liner with a thickness of 1.5mm or more, a width greater than 6 meters, and incorporating a rough surface texture on slopes ensures effective containment and seepage prevention in solid waste landfills.

4. How To Install HDPE geomembrane Liner?
Roll the surface to be laid and leveled, dig the blind ditch, and vent the exhaust pipe. More specific base processing can be handled according to design requirements.
After laying the geoprotective liner, the HDPE geomembrane liner can be laid. Prepare heavy objects such as sandbags and compact the paved HDPE geomembrane liner so that the wind does not blow up. When laying, the weld seam should be minimized, and the most suitable laying plan should be selected according to the actual site size.
Before welding, test welding first, and select the appropriate welding parameters according to the climate of the day. When welding, professional welding equipment should be used. For large-area welding of HDPE geomembrane liner, double-track hot-melt automatic crawling welding machine is adopted; for T-shaped and cross-shaped welding and filling, hot-melt extrusion welding machine should be used.
Steep slope welding with rope ladders or scaffolding. Welder technicians need to take safety measures.
Anchorage trench excavation: U-shaped ditch with anchorage groove size of 50cm×50cm×50cm, backfill or concrete with concrete; steep slope can be excavated and then anchored for anchoring; anchoring nail and bead can be used for rock layer Perform an anchor seal.
