How to Choose the Width of Geomembrane?
In anti-seepage engineering, geomembrane is an ideal material, and the selection of geomembrane with excellent quality is very important.
Width is an important parameter of geomembrane, and a wider width can bring many benefits to anti-seepage projects.
For projects with larger laying areas such as tailings dams liner, geomembrane materials with wider widths should be used.
In anti-seepage engineering, the most likely leakage point is the welding part of the geomembrane.
The wider the width of the geomembrane, the fewer welds will be needed during the actual welding construction.
In addition, the increase of the width and the reduction of the welding seam also bring two other favorable conditions.
One is to reduce the lap loss during welding construction: comparing 8 meters width geomembrane with 7 meters width geomembrane,
the theoretical loss rate can be reduced by 14%, which is conducive to saving the cost of the project.
Another point is that due to the reduction of welds, the time and labor required for welding will also be reduced,
which can reduce the construction period of the anti-seepage project and the corresponding labor costs.
This advantage is particularly evident in some large-scale anti-seepage projects with strict construction period requirements.
The laying order of the geomembrane should be based on the principle of the bottom first and the bank later.
After the geomembrane is laid, professionals are required to conduct strict inspections, and the unqualified parts need to be dealt with in time.
Width:1-10m. 5.8/7m width is common. Suitable for container shipping.
9m width is also used for large projects.
