All seams must be continuous (for example, the point of the slit is not allowed). In the overlap before the geotextile must overlap at least 150mm. Minimum distance selvedge needle (material exposed edges) is at least 25mm. Geotextile sewn seams and most include a line-shaped wire locking chain stitch. Geotextile manufacturers suture line should be used as the minimum tension over 60N resin material, and with equal or exceed geotextile resistance to chemical corrosion and UV resistance. Any geotextile sewn on the "leak needle" in the affected areas must be re-stitched. Must take appropriate measures to avoid after installation, soil, particulate matter or foreign substances into the geotextile layer. Lap cloth according to the terrain and the use of functions can be divided into natural lap, stitched or welded. In construction, geotextile geomembrane above the natural overlap, the upper geotextile geomembrane seam or hot air welding. Hot air soldering is the first connection geotextile filament method, which uses hot air gun connection of the two pieces of cloth instantaneous high temperature heating to achieve the molten state part and immediately using a predetermined force to firmly bonded together . In the wet (rain and snow) weather can not be connected to the case of heat-bonding, geotextile Method one suture should be taken to connect to another method, which uses special sewing machine stitching wire connection, and the use of anti-chemical UV sutures. Seams shall slope lines intersect; and toe balance or stress that may exist where the distance between horizontal joints must be greater than 1.5m. On the slope of the geotextile be anchored at one end, then roll down the slope required to ensure geotextile kept taut state. Must examine all of the pieces and sewn geotextiles. Geotextile sheet defective and stitching must be clearly marked on the geotextile and repair. In the bottom of the landfill, if the geotextile membrane gap width exceeding 10%, shall damaged part removed, and then the two geotextiles connection; if on the slope, rip more than 10% of web width, shall send Volume geotextile removed and replaced with a new roll.
