Double-smooth surface · best weldability · horizontal liners
Smooth HDPE Geomembrane: Smooth HDPE geomembrane is a double-sided flat liner with stable hot-wedge weldability and the lowest unit cost among geomembranes. Use it on horizontal surfaces and gentle slopes gentler than 1:2.5, such as fish pond bottoms, reservoir basins, lake beds, oxidation pond floors and landfill base. For steeper slopes switch to single or double textured membranes.

Smooth geomembrane has flat glossy surfaces on both sides, offering mature welding practice and lower cost. It is the mainstream choice for pond bottoms, reservoir basins and landfill base liners. Yurun supplies 0.5-3.0mm in 1-8m widths.
| Item | Specification |
|---|---|
| Thickness | 0.5 / 0.75 / 1.0 / 1.25 / 1.5 / 2.0 / 2.5 / 3.0mm |
| Thickness tolerance | within ±10% |
| Width | 1m-8m |
| Elongation at break | ≥700% |
| Yield strength | 1.5mm ≥22N/mm; 2.0mm ≥29N/mm |
| Suitable slope | Horizontal to 1:2.5 |
| Welding | Double-seam hot wedge; extrusion at details |
| Type | Features | Application | Typical works |
|---|---|---|---|
| GH-1 general grade | Standard national indicators | General water works | Fish ponds, canals |
| GH-2 environmental grade | Higher strength & crack resistance | Pollution-risk works | Sewage ponds, landfill base |
| Wide-width 6-8m | Fewer seams per area | Large basins | Reservoirs, lakes, landfill cells |
| Common problem | Yurun Geosynthetics solution |
|---|---|
| Too many seams in large basins | 6-8m wide rolls reduce seam count and leak paths |
| Slipping on slopes | Use smooth only on flat/gentle areas; textured on slopes by zone design |
| Uncontrolled weld quality | Trial weld parameters, air-pressure testing and on-site guidance provided |
Note: the sequence above is general practice. Final parameters follow the project design and site conditions; free technical guidance is provided.
Dezhou Yurun Geosynthetics Co., Ltd. is a source manufacturer with its own geomembrane and geotextile production lines — not a trading company. Smooth HDPE Geomembrane is produced and inspected to current national standards with third-party batch test reports. Common specifications are kept in stock, and cut-to-size production is available against your layout drawing. Nationwide supply and export, with free selection advice and welding guidance.
Smooth for flat and gentle areas (cheaper, easiest welding); single-textured for 1:2.5-1:3 slopes; double-textured for slopes ≥1:1.5. Zoning saves cost while keeping slope safety.
Set by trial weld per machine, film thickness and weather; below 5°C preheat and increase sampling.
