|Title||Filament Nonwoven Geotextile Installation|
|Description||Filament Nonwoven Geotextile Installation 1. With manual rolling install, top quality filament nonwoven geotextile surface must be level, and appropriate deformation allowance. 2. The installation of filament nonwoven geotextile price or short fiber nonwoven geotextile usually adopts several methods of splice, suture, and welding. The width of suture and welding is usually quite 0.1m, and therefore the lap width is usually quite 0.2m. polyester nonwoven geotextile factory price which will be exposed for an extended time should be welded or sewn together. 3. Geotextile Suture: All stitches must be continuous (for example, point stitches aren't allowed). Filament nonwoven geotextile purchasable must overlap a minimum of 150mm before overlap. The minimum stitch distance from the sting (the exposed fringe of the material) should be a minimum of 25mm. The filament nonwoven geotextile price joints that are sewn most include 1 line of cable locking chain stitch method. The thread used for suture shall be resin material with a minimum tension of quite 60N and shall have an equivalent or greater resistance to chemical corrosion and ultraviolet as a geotextile. Any “needle leakage” on the geotextile must be re-sewn where it's affected. Appropriate measures must be taken to stop soil, particulate or foreign matter from entering the geotextile layer after installation. The splice of fabric is often divided into natural splice, seam joint or welding consistent with the topography and use the function. 4. within the construction, the HDPE geomembrane above the polypropylene nonwoven geotextile for sale shall be overlapped naturally, and therefore the HDPE geomembrane on the upper layer, the filament nonwoven geotextile purchasable shall be seamed or welded by hot air. Hot air welding is that the preferred connection method of filament geotextile, that is, the connection of two pieces of fabric with a hot air gun is instantly heated at heat, in order that a part of it reaches the melting state, and immediately use a particular external force to form it firmly bonded together. In wet (rain and snow) weather can't be hot adhesion connection, geotextile should adopt another method a suture connection method, that is, a special home appliance for double suture connection, and therefore the use of anti-chemical ultraviolet suture line. The minimum width at suture is 10cm, the minimum width at natural lap is 20cm, and therefore the minimum width at hot air welding is 20cm. 5. For seam joints, an equivalent quality as geotextile should be used, and therefore the suture line should be made from materials with stronger resistance to chemical damage and ultraviolet irradiation. 6. Geomembrane shall be laid after the geotextile laying and approved by the on-site supervision engineer.|
