Method of laying the geotextile
Use manual rolling; the cloth surface shall be flat and have appropriate deformation allowance.
Suture of the geotextile: All sutures must be performed continuously (for example, the point seam is not allowed). Before the overlap, the geotextile must overlap at least 150mm. The minimum needle distance is at least 25mm (the edge of the exposed material). The sewn geotextile joint includes 1 line and line lock chain joint method. The thread for suture shall be resin material with minimum tension exceeding 60N and have chemical corrosion and UV resistance equivalent to or beyond the geotextile. Any "missed needle" on sewn geotextiles must be resewn in the affected area. Corresponding measures must be taken to avoid entering the soil, particulate material or foreign material into the geotextile layer after installation. The lap of cloth can be divided into natural lap, seam connection or welding according to the terrain and use function.
