How many sqm per roll hdpe geomembrane 1.5mm
HDPE geomembrane 1.5mm is a medium-thickness high-density polyethylene liner used for impermeable containment in landfills, mining, and water projects, offering a balance between mechanical strength, flexibility, and installation efficiency.
How Many SQM per Roll HDPE Geomembrane 1.5mm?
The square meter coverage per roll depends on roll width and length. The most common configurations are:
| Roll Width (m) | Roll Length (m) | Total Area (sqm) | Approx. Weight (kg) |
|---|---|---|---|
| 5.8 | 100 | 580 | ~810 |
| 6.0 | 100 | 600 | ~840 |
| 7.0 | 100 | 700 | ~980 |
| 8.0 | 100 | 800 | ~1120 |
| 7.0 | 140 | 980 | ~1370 |
Conclusion: Standard HDPE geomembrane 1.5mm rolls typically range from 580 sqm to 980 sqm per roll, depending on factory configuration and logistics constraints.
