HDPE Geomembrane: Textured
A high-performance seepage-proof material, available in single-sided and double-sided textured surface.
HDPE textured geomembrane is a high-performance impermeable material, designed for applications requiring higher interfacial friction. Our products can be manufactured according to GB/T, ASTM, ISO, or other standards, all made from high-purity new HDPE resin. By creating a uniform texture on the geomembrane surface, it significantly enhances friction with contact materials such as geotextiles, sand, or geogrids. HDPE textured geomembrane combines all the superior properties of smooth geomembranes with the engineering performance of a high-friction surface
Production Process: Manufactured using a multi-layer co-extrusion blow molding process, which roughens the surface with nitrogen to create a uniform and durable raised texture. The average roughness height is ≥0.25mm, and the minimum is ≥0.20mm. The texture is firm and not easily worn off during construction.
Quality Control: The entire production process is monitored by automation. Strict factory inspections are conducted in accordance with standards, to ensure that the dimensions, appearance, and key properties (such as tensile strength and puncture resistance) of each roll of product exceed the standard requirements.
After-sales Service: We have over one million square meters of construction experience, and our team can provide on-site construction services. We also offer remote technical guidance to assist with welding and construction.

- Slope Protection Engineering:
- Seepage prevention for landfill slopes, tailings dam slopes, and earth-rock dam slopes of reservoirs.
- Landfill Capping System:
- Used in conjunction with geonets and geotextiles to form a stable final capping layer.
- Special Foundation Treatment:
- Used for soft foundations or sites prone to uneven settlement, utilizing friction to disperse stress.
- Roof Gardens and Green Walls:
- Serves as a waterproof and root-barrier layer, while also providing a surface conducive to the anchoring of vegetation.
