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.
