White or black Geotextile laying methods:

First of all, Use artificial rolling; the cloth surface should be flat, and the deformation allowance should be left as appropriate.

Secondly,  Filament or short white or black nonwoven geotextile installations are usually lapped, stitched and welded. The width of the stitching and welding is generally 0.1 m or more, and the overlap width is generally 0.2 M or more. White or black nonwoven geotextile that may be exposed for a long time should be welded or stitched.

To the third step, white or black nonwoven geotextile stitching: All stitching must be done continuously. For example, point stitching is not allowed. White or Black nonwoven geotextile should be overlapped a minimum of 150 mm before overlapping. The minimum stitch distance is at least 25 mm from the selvedge, as the exposed edge of the material.

The seams of the well-stitched white or black nonwoven geotextile include the one-line and the chain-locking chain stitching method. The thread used for stitching shall be a resin material with a minimum tension of more than 60 N and a chemical resistance and UV resistance equivalent to or exceeding that of nonwoven geotextile. Any "leakage needle" on the sewed nonwoven geotextile must be re-sewed in the affected area. Corresponding measures must be taken to prevent soil, particulate matter or foreign matter from entering the wihte or black nonwoven geotextile after installation. The lap joint of the cloth can be divided into natural lap joint, seam joint or welding according to the terrain and the function of use.
