The geotextile roll should be protected from damage before installation and unfolding. Geotextile rolls should be stacked in a flat and waterlogged area, with a height of no more than four rolls and visible identification plates of the rolls. Geotextile rolls must be covered with opaque material to prevent UV aging. During storage, it is important to maintain the integrity of the labels and information. During the transportation process (including on-site transportation from the material storage location to the work site), the geotextile roll must be protected from damage.
Geotextile rolls that have been physically damaged must be repaired. Geotextiles that are severely worn cannot be used. Any geotextile that comes into contact with leaked chemical reagents is not allowed to be used in this project.
