Double rough geomembrane is a geomembrane with rough surfaces on both sides. Double rough geomembrane has a wide range of uses. Double rough geomembrane can contact geotextiles on both sides in the construction of slope anti-seepage projects, thus achieving an anti-slip effect.
Rough surface HDPE geomembrane has excellent temperature adaptability, weldability, weather resistance, aging resistance, chemical corrosion resistance, environmental stress cracking resistance and puncture resistance. It is mainly used for steep slope anti-seepage, and its purpose is to enhance the friction between the geomembrane and the slope surface to prevent sliding and improve the stability of the project.
Double rough surface geomembrane is a waterproof material made of polymer material with the characteristics of double-sided roughness. Its surface roughness is moderate, which can be closely combined with the soil to effectively prevent water penetration and leakage. At the same time, the double rough surface geomembrane also has high tensile strength, elongation and aging resistance, and can adapt to various harsh environmental conditions. In the construction of slope anti-seepage projects, the double-sided rough geomembrane can contact with geotextiles to play an anti-slip role.
✦Advantages and characteristics of double rough geomembrane
Good waterproof performance
Double rough geomembrane is made of polymer materials and has excellent waterproof performance. Its surface roughness is moderate, and it can be closely combined with the soil to form an effective waterproof barrier to prevent water penetration and leakage.
Excellent friction
Double rough geomembrane adopts a double-layer rough surface design, forming a certain degree of roughness, thereby enhancing the friction between it and the soil. This friction can effectively prevent the sliding and displacement of the geomembrane in the soil, and improve the stability and reliability of the geomembrane.
High durability
Double-surface geomembrane has high tensile strength, tear strength and puncture resistance, can withstand large tensile force and deformation, can effectively resist stress concentration and damage risk in the soil, and ensure the stability and safety of the engineering structure
Good aging resistance and chemical corrosion resistance
Double-surface geomembrane is made of polymer materials, has good aging resistance and chemical corrosion resistance, can withstand long-term environmental erosion and load, and can maintain its original performance for a long time under different environmental conditions, and is not affected by ultraviolet rays, oxidation, acid and alkali and other factors.
Convenient construction
Double-surface geomembrane has good plasticity and toughness, is easy to construct, can adapt to various complex construction environments and conditions, and greatly improves engineering efficiency. At the same time, its double-sided roughness can also be closely combined with the soil, reducing the risk of water leakage during construction.
Environmental protection
Double-surface geomembrane has little impact on the environment during production and use. It is made of environmentally friendly materials, non-toxic and harmless and recyclable. During use, it can effectively reduce the damage and pollution of the project to the environment and promote sustainable development.

This product flyer is intended for reference purposes. It should not be used in place of the advice from a licensed Professional Engineer. Nominal pressure (PN) is based on C = 1,25 and an operating temperature of 20°C. Weight is calculated using DN and Minimum wall plus 6% for use in estimating fluid flow. Actual ID will vary. When designing components to fit the pipe ID, refer to pipe dimensions and tolerances in the applicable pipe manufacturing specification. To obtain pressure in psi, multiply bar by 14.5 (1 bar ≈ 14.5 psi). Additional information is available at www.bingopipes.com.
