1. Geotextiles can only be cut with a geotextile knife (hook knife). If cut within the site, special protective measures must be taken for other materials to prevent unnecessary damage caused by cutting the geotextile;
2 2. While laying geotextile, all necessary measures must be taken to prevent damage to the underlying layer of material;
3 3. When laying geotextiles, attention must be paid not to allow substances such as stones, a large amount of dust or moisture that may damage the geotextile, block drainage channels or filter screens, or cause difficulties for subsequent connections to enter the geotextile or beneath the geotextile;
4 4. After installation, visually inspect all geotextile surfaces to identify all damaged landlords, mark and repair them, and ensure that the laying surface is free of foreign substances that can cause damage, such as broken needles;
5 5. The connection of geotextile must comply with the following regulations: under normal circumstances, there must be no horizontal connection on the slope surface (the connection must not intersect with it along the contour of the slope surface), except for the repaired area.
6 6. If stitching is used, the suture must be made of materials that are the same or more than the geotextile material, and the suture must be made of material that is resistant to chemical ultraviolet radiation. There should be a significant color difference between the suture and the geotextile for easy inspection.
7 7. Pay special attention to stitching during installation to ensure that no soil or gravel from the gravel cover layer enters the middle of the geotextile.
