Rough geomembrane is an anti-seepage material with a rough texture on the surface through a special process. It is mainly used to enhance the stability of engineering structures.
1. Basic composition
Using high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE) as raw materials, it is manufactured through processes such as blow molding and calendering, and the surface presents a uniform granular or columnar texture.
2. Main types
Manufacturing process
Use special formula resin, through film blowing or calendering process, some products add nitrogen blowing to enhance surface friction performance.
Implementation standards
National standard GB/T17643-2011, urban construction standard CJ/T234-2006, some products are equivalent to American standard GRI-GM13.
1. High friction coefficient
The rough surface design increases the friction coefficient by 30%-50%, which is suitable for steep slopes (>1:3) and vertical anti-seepage projects to prevent slippage between geomembranes and soil.
2. Mechanical properties
The tensile strength can reach 35MPa, the elongation at break is ≥100%, and the environmental stress cracking resistance is excellent.
3. Chemical stability
It is resistant to acid, alkali, oil, and ultraviolet aging, with a service life of more than 50 years, suitable for corrosive environments such as landfills and chemical sewage pools.
1. Environmental protection projects
Landfill base/slope anti-seepage, sewage pool lining, hazardous waste closure.
2. Water conservancy projects
Reservoir dam slope, river slope protection, tailings pond anti-seepage, especially suitable for steep terrain.
3. Agriculture and breeding
Fish ponds, lotus ponds, biogas pools anti-seepage, to prevent soil erosion.
Comparison with smooth geomembrane
| FEATURE | ROUGH | SMOOTH |
| Surface texture | Rough/pillar-shaped | Smooth and flat |
| Friction coefficient | High(0.4-0.6) | Low(0.2-0.3) |
| Applicable scenarios | Steep slope, vertical anti-seepage, anti-slip scenes | Scenarios requiring flat surface anti-seepage and low friction |
| Welding Difficulty | Special equipment is required (such as a large pressure welder) | Ordinary hot melt welding |
1. Laying direction
Extend from high position to low position, leaving 1.5% margin to accommodate settlement deformation.
2. Welding process
High-pressure welding equipment is required for rough surface areas, and the weld overlap width is ≥10cm to avoid impurity contamination.
3. Edge treatment
Some products are designed with smooth edges (width 10-30cm) to facilitate traditional welding processes.
