Precautions for installation and construction of geotextiles:

1. The geotextile can only be cut with a geotextile knife (hook knife). If it is cut in the field, special protection measures must be taken for other materials to prevent unnecessary damage to the geotextile due to cutting;

2. When laying geotextiles, all necessary measures must be taken to prevent damage to the material below;

3. When laying geotextiles, care must be taken not let stones, large amount dust or moisture, etc., that may damage the geotextiles, may block drains or filters, or may cause difficulties for subsequent connections into the geotextiles. or under the geotextile;

4. After the installation is completed, visually inspect the surface of all geotextiles to determine all damaged areas, mark and repair them, and make sure that there are no foreign substances that can cause damage on the paved surface, such as broken needles and other foreign objects;

5. The connection of geotextiles must follow the following regulations: under normal circumstances, there should be no horizontal connection on the slope (the connection must not intersect with the contour of the slope), except the repaired place.

6. If suture is used, the suture must be made of the same or more than the material of the geotextile, and the suture must be made of anti-ultraviolet material. There should be obvious color difference between the suture and the geotextile for easy inspection.

7. Pay special attention to the stitching during installation to ensure that no dirt or gravel from the gravel cover enters the middle of the geotextile.

Geotextile damage and repair:

1. At the suture junction, it is necessary to re-suture and repair, and make sure that the end of the skip stitch has been re-sutured.

2. In all areas, except rock slopes, leaks or torn parts must be repaired and stitched with geotextile patches of the same material.

3. At the bottom of the landfill, if the length of the crack exceeds 10% of the width of the roll, the damaged part must be cut off, and then connect the two parts of the geotextile.
