6. Polyester Geotextile Installation Method
6.1 Manual Laying
Geotextiles should be laid manually; the surface should be flat and allow for deformation.
6.2 Overlapping and Joining Methods
Nonwoven geotextile fabric is typically installed using overlapping, sewing, and welding methods. The width of seams and welds is generally 0.1m or greater, and the overlap width is generally 0.2m or greater. Geotextiles that may be exposed for extended periods should be welded or sewn.
6.3 Polyester Geotextile Sewing
All seams must be continuous (i.e., spot seams are not permitted). Before overlapping, the geotextile must overlap by a minimum of 150mm. The minimum distance between stitches and the selvedge (exposed edge of the material) is at least 25mm.
Sewn geotextile seams must consist of a single row of double-threaded chain stitches. The sewing thread should be a resin material with a minimum tension exceeding 60N and possess chemical and UV resistance equal to or greater than that of the geotextile.
Any "missed stitches" in a sewn geotextile must be resewn at the affected location.
Appropriate measures must be taken to prevent soil, particulate matter, or foreign matter from entering the geotextile layer after installation.
Overlapping geotextiles can be categorized as natural overlap, sewing, or welding, depending on the terrain and intended use.
6.4 Installation Above Geomembranes
During construction, the geotextile above the geomembrane should be naturally overlapped, while the geotextile above the geomembrane should be sewn or hot-air welded. Hot-air welding is the preferred method for joining filament geotextiles. This involves using a hot air gun to instantly heat the two pieces of fabric to a high temperature, partially melting them, and then applying a certain amount of force to firmly bond them together. In humid weather (rain or snow), when hot-gluing is not possible, the geotextile should be joined using an alternative method: sewing. This involves double-stitching with a dedicated sewing machine, using chemically UV-resistant thread.
The minimum width for sewing is 10 cm, while the minimum width for natural overlap and hot-air welding is 20 cm.
6.5 Seam Material Requirements
For seams, use sutures of the same quality as the geotextile, and use materials that are more resistant to chemical damage and ultraviolet light.
7. Summary
Selecting Polyester Geotextile is a systematic manner that requires a complete contrast of more than one factors, inclusive of geo fabric properties, overall performance indicators, software scenarios, producer reputation, and market price.
