Single / double textured · high friction · slope liners
Textured HDPE Geomembrane: Textured HDPE geomembrane has a roughened surface (texture height ≥0.25mm) to increase interface friction and prevent liner slippage on slopes. Choose single-textured for slopes of 1:2.5-1:3 and double-textured for slopes steeper than 1:1.5, such as landfill side slopes, tailings dam faces and hazardous-waste cells; keep smooth membrane for flat base areas to control cost.
Textured geomembrane carries uniform rough texture (≥0.25mm) that greatly raises interface friction against geotextile and soil, preventing slope slippage. It is mandatory for landfill slopes, tailings dam slopes and steep containment walls. Yurun supplies single and double textured types.

Dezhou Yurun Geosynthetics Co., Ltd. is a source manufacturer with its own geomembrane and geotextile production lines — not a trading company. Textured HDPE Geomembrane is produced and inspected to current national standards with third-party batch test reports. Common specifications are kept in stock, and cut-to-size production is available against your layout drawing. Nationwide supply and export, with free selection advice and welding guidance.
Single-textured suits moderate slopes with the rough side toward the cover; double-textured gives the highest interface friction for slopes ≥1:1.5. Double costs more than single.
Yes for slope stability; base may stay smooth. Thickness ≥1.5mm per GB 55012-2021.
1.5-2.0mm double-textured on dam faces; verify chemical resistance for acidic/alkaline tailings.
Dezhou Yurun Geosynthetics Co., Ltd. is a source manufacturer of geosynthetic anti-seepage materials, located in the geosynthetic industrial cluster of Lingcheng District, Dezhou City, Shandong Province, China.
