Indus Industrial Group supplies high-performance HDPE Double-Sided Textured Geomembrane Liners manufactured in thicknesses of 1.5mm (60 mil), 2.0mm (80 mil), and 2.5mm (100 mil) in seamless roll widths up to 7.0 meters. Certified in accordance with the international GRI-GM19 specification, these specialized geomembranes feature co-extruded textured surfaces with raised friction asperities on both sides. Engineered for steep embankment slopes in municipal wastewater oxidation lagoons, hazardous landfill containment cells, and deep water reservoirs, the textured profile prevents slope slippage of overlying soil, geotextile protective layers, and maintenance personnel.

Wastewater treatment oxidation lagoon slopes, municipal solid waste landfill side-slope containment, oilfield drilling mud pit lining, and steep canal embankments in Basra, Baghdad, Erbil, Sulaymaniyah, and Maysan.
Lining steep earthen slopes (greater than 3H:1V) in water reservoirs, mining tailings ponds, and sanitary landfills presents severe geotechnical challenges. Smooth geomembranes have very low surface friction, causing overlying protective earth layers, sand ballast, or nonwoven geotextiles to slide catastrophically down the embankment. Indus Double-Sided Textured Geomembrane Liners solve this slope stability challenge by co-extruding a dense, uniform matrix of raised polyethylene asperities (minimum 0.40mm texture height per ASTM D5994).
The aggressive textured surface dramatically increases the interface friction angle (shear strength) between the geomembrane and adjacent soil or geosynthetic clay liners (GCL), allowing geotechnical engineers to design steeper canal and lagoon bank slopes (up to 2H:1V). This steeper slope design maximizes effective water storage volume while substantially reducing earthmoving excavation and land acquisition costs across Iraqi infrastructure projects.
Extruded from virgin polyethylene resin fortified with furnace carbon black and antioxidants, the membrane delivers the same chemical and UV resistance as smooth HDPE, resisting corrosive wastewater effluents, leachates, and harsh Middle Eastern desert sunlight. Indus maintains extensive stocks in Erbil and Basra.
Smooth geomembrane has a very low friction angle (approx 8°–11°), which causes protective soil, riprap, or workers to slip on wet slopes. Textured geomembrane increases the friction angle to over 28°, holding cover materials securely on steep embankments.
Yes. Modern dual-track hot wedge welding machines easily weld textured geomembranes. Some contractors prefer using rolls with a smooth welding edge (untextured 100mm margin) for ultra-fast wedge speed.
Double-sided texturing is recommended when the geomembrane sits between an underlying geotextile/GCL and an overlying soil cover layer, locking both interfaces against slope failure.
