Textured Geomembrane liner has rough surface on either one or both sides which can highly improve the friction coefficient which fits more suitable for steep slope and vertical engineering design work which maximize the effective volume of geomembrane. As the leading geomembrane manufacturer and supplier, GEOSINCERE textured geomembrane is produced with approximately 97.5% virgin polyethylene, 2.5% carbon black and trace amounts of anti-oxidants and heat stabilizers by the automatic extrusion and spraying technology, the edges are also carefully processed smoothly to allow for high quality thermal fusion welding between adjacent connection. Textured geomembrane meets or exceeds the requirements of is ASTM D7466 – Standard Test Method for Measuring Asperity Height of Textured Geomembrane. This test method measures the height from the core membrane to the top of the texture peak.
Compared with smooth HDPE geomembrane, the textured HDPE geomembrane not only has the same features such as high tensile strength, tear resistance, puncture resistance, lowest permeability, alkali and acid resistance, also has superior shear strength, high multi-axial performance, excellent interface friction properties in combination with outstanding longevity. The textured surface processing is the only one that produces a textured material without significant reduction of any physical properties. The product allows project for greater slopes to be designed since frictional characteristics are enhanced. The textured geomembrane is suitable for such applications as retaining backfill on steep side slopes, landfill and pad baseline, heap leach pads, solid waste landfills, hazardous waste landfills, mining, coal ash pond, animal waste containment, etc.
GEOSINCERE provides high quality custom textured geomembrane with complete thickness, size and specifications at competitive factory price.

Textured geomembrane material is primarily made from high-density polyethylene (HDPE) raw material. HDPE is a commonly used polymer that possesses excellent chemical resistance, durability, and flexibility, making it well-suited for geomembrane applications. The textured surface is created during the manufacturing process by imprinting patterns or textures onto the HDPE material.
This texturing enhances the geomembrane’s frictional properties and stability, allowing it to effectively prevent seepage and provide slope protection in various engineering projects. The use of relatively virgin HDPE raw material ensures that the textured geomembrane meets the necessary quality standards and provides reliable performance in environmental and civil engineering applications.
Similar to smooth geomembrane, the industry standard textured geomembrane thickness is typically measured in millimeters (mm) or mils (thousandths of an inch). Common thicknesses range from 0.5 mm (20 mils) to 3.0 mm (120 mils) or more. The selection of the appropriate thickness depends on factors such as the type of containment, environmental conditions, and the level of protection required.
The textured HDPE geomembrane liner is specifically engineered for geotechnical projects that necessitate slope stability. Its high-friction textured surfaces make it an optimal choice for anti-seepage lining, delivering heightened frictional resistance, excellent chemical resistance, and exceptional durability. The textured surface bolsters its capacity to confront slope design challenges, fortifying stability and averting seepage. With its distinctive attributes, the textured HDPE geomembrane liner is well-suited for applications that require augmented frictional resistance, thereby ensuring dependable performance across diverse geotechnical endeavors.
These applications include retaining backfill on steep side slopes, landfill and pad baseliners, heap leach pads, solid waste landfills, hazardous waste landfills, mining operations, coal ash ponds, and animal waste containment. By employing the textured HDPE geomembrane liner, these projects benefit from its ability to mitigate seepage, provide stability against slope-related issues, and maintain performance integrity in the face of various environmental factors. The liner’s tailored design and enhanced frictional properties make it an indispensable solution for geotechnical projects where slope requirements and effective anti-seepage measures are of paramount importance.
