Cautions for laying composite geomembrane

1. Composite geomembrane materials need to be inspected before construction.

2.Cleaning of embankment slope before construction: leveling the site and removing all sharp corner debris. After the preparatory work is finished, the site shall be checked and accepted. It provides a working face for the laying of composite geomembrane.

3.In order to construct conveniently and ensure the splicing quality, the composite geomembrane should be as wide as possible. This can reduce the amount of field stitching.

Before construction, the composite geomembrane should be tailored in the unit according to its width and site length, and spliced into blocks of the required size. Then roll it on the steel pipe and carry it manually to the working face for laying.

4.Laying method of composite geomembrane:

Composite geomembrane laying is divided into two parts: bottom laying and slope laying.

First, the composite geomembrane is rolled horizontally along the axis of the channel. After checking the slope surface, another piece of geomembrane is rolled along the axis of the slope surface. Finally, it is connected with the composite geomembrane at the bottom of the canal in a "T" shape.

5.Technical requirements for laying composite geomembrane:
