The geotextile roll should be protected from damage before installation and unfolding. Geotextile rolls should be stacked in a flat place without water accumulation, the height of the stack should not exceed the height of four rolls, and the identification film of the roll can be seen. Geotextile rolls must be covered with opaque materials to prevent UV aging. In the storage process, the integrity of the label and the integrity of the data should be maintained.
During the transportation process (including the transportation from the material storage site 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 in contact with leaking chemical reagents is not allowed to be used in this project.
