When containment runs over slopes, smooth geomembrane slips: the cover soil, the waste or the water push the sheet down the incline and compromise the stability of the works. This textured HDPE geomembrane —also called textured liner or rough geomembrane— solves that problem with a relief surface on both sides that multiplies interface friction. Manufactured by Moltexo with professional-grade virgin resins in gauges from 4000 to 8000 (1.0 to 2.0 mm), it is designed for landfills, mining and steep-walled reservoirs where slope stability is audited: never as a temporary solution.
Key benefits
- Superior interface friction: texture on both sides with an asperity height ≥ 0.40 mm (ASTM D7466), which increases the friction angle against soil and other geosynthetics and keeps the cover stable on steep slopes.
- Certifiable slope stability: verifiable direct shear behavior per ASTM D5321 / D6243, the data required by the stability calculation in landfill cells and leach pads.
- Same UV and chemical resistance as the smooth version: carbon black content of 2.0 to 3.0 % (ASTM D1603) and OIT retention after UV aging, to withstand years under the direct Caribbean sun without degrading.
- HDPE mechanical durability: resistance to tensile stress, puncture, tear and stress cracking (ESCR) in accordance with the GRI-GM13 family of specifications for textured geomembrane.
- Careful Moltexo manufacturing: professional-grade virgin polymer, individual minimum thickness with controlled tolerance and verified ASTM tests on every gauge.
Applications and typical uses
- Lining of slopes and inclined walls in sanitary landfill cells and secure landfills.
- Leach pads (leach pads) and tailings deposits in mining projects.
- Reservoirs, dams and oxidation ponds with steep slopes.
- Final cover systems (capping) where the topsoil must hold on the sheet without slipping.
Quality and durability
Each variant meets the reference tests for textured HDPE: asperity height per ASTM D7466, tensile properties per ASTM D6693 and stress crack resistance (ESCR) per ASTM D5397, with the same UV protection as the smooth line. The texture is produced integrally during manufacturing —it is not a smooth sheet onto which a surface relief is printed— so the relief is not crushed under load nor lost over time. Moltexo also controls the individual minimum thickness with a −10 % tolerance on each roll, a requirement that simply does not apply to low-cost materials.
