How is the geotextile made?

The geotextile is manually rolled. It is required that the cloth surface shall be flat, and the deformation allowance shall be reserved properly. During the construction, the geotextile above the geomembrane shall be overlapped naturally, and the geotextile below the geomembrane shall be welded by seam or hot air.

How to inspect the surface of geotextiles laid on that day?

Before the end of each day’s laying, the surface of all geotextiles laid on that day shall be visually inspected to make sure that all the damaged places have been marked and repaired immediately, and to make sure that the laying surface is free of foreign substances that may cause damage, such as fine needles, small iron nails, etc.
