High-Strength HDPE Textured Geomembrane for Enhanced Stability and Performance
Overview of Sprayed Rough Geomembrane
Sprayed Rough Geomembrane is a special geosynthetic material, mainly used for anti-seepage, anti-skid and enhancing the stability of engineering structures. It is based on the traditional production process of polyethylene anti-seepage membrane. By updating the production equipment, the surface of the polyethylene anti-seepage membrane produced forms a granular rough surface, thereby improving the friction performance of the geomembrane surface
Characteristics and Applications
Characteristics
Reliable anti-seepage effect: The permeability coefficient of the sprayed rough geomembrane is small, which can effectively prevent liquid penetration.
Easy to lay: Its design is convenient for construction personnel to lay.
High strength: It has high tensile strength, elongation at break and puncture resistance.
Stable material: It has strong resistance to chemical agents and can maintain stable performance in various harsh environments.
High joint strength: The joints are double-seam connected by a hot welding machine to ensure that the joints are not prone to leakage1.
Application
Sprayed Rough Geomembrane is widely used in engineering projects that require anti-seepage and enhanced friction, especially in projects where the surface of the slope membrane needs to be covered with soil and requires a large friction coefficient. For example, landfills, tailings storage sites, channel anti-seepage, dam anti-seepage and subway projects, etc.
Types
Sprayed rough geomembranes are available in two types: single rough surface and double rough surface. The specific choice depends on the project requirements. Both single rough surface geomembranes and double rough surface geomembranes are made of specially formulated virgin resins and produced by special processes. Among them, double rough surface geomembranes have more rough textures on their surfaces, so they perform better in increasing the friction coefficient and anti-slip function, and are more suitable for steep slopes and vertical anti-seepage projects
Manufacturing and materials
Sprayed rough geomembranes are usually made of high-density polyethylene (HDPE) or polypropylene as raw materials, and are refined through professional production equipment and special production processes. This material has excellent temperature adaptability, weldability, weather resistance and good aging resistance, making it an ideal choice for many high-demand projects
Conclusion
Sprayed rough geomembranes are a high-performance anti-seepage material. With its unique surface rough texture, it significantly improves the friction coefficient and anti-slip performance, and is widely used in various projects that require anti-seepage and enhanced friction. Whether it is single-surface or double-surface geomembrane, we can provide reliable solutions according to specific engineering needs.
